Product Details
The Helix Midnight is one of the most balanced and affordable hybrid models we’ve tested in our lab. Although the mattress is specifically designed for side sleepers between 130 and 230 pounds, our tests also reveal sufficient support for back and stomach sleepers who weigh under 130 pounds. Breathable construction, sturdy edges, and comfortable bounce add to the Midnight’s appealing design.
What It’s Made of
The Midnight begins with a top layer of memory foam, followed by two polyfoam layers. These materials provide some cushioning, but they are dense and responsive enough to keep your body aloft. Pocketed coils and dense base foam make up the base layers. The long sides are lined with thicker coils to push back against your weight, so you shouldn’t notice any sinkage when lying along the edges or getting in and out of bed. A breathable cover encases the mattress. You can swap in a GlacioTex cover with heat-dissipating phase change material (PCM) for an extra fee.
We’ve rated the Midnight as medium firm, or a 6 on our 10-point firmness scale. The mattress measures 11.5 inches thick. Helix also offers an upgraded version of the mattress known as the Midnight Luxe, which builds on the initial design with an extra foam layer encased in a Euro-top cover, zoned coils that provide enhanced support to the midsection, and a cover made of moisture-wicking Tencel fabric.
How It Performed
Foam hybrids have a tendency to sleep hot, but the Midnight resists heat buildup thanks to its medium firm feel. You’re less likely to sink into the mattress and lose surface airflow, and the coils generate enough airflow to maintain a comfortable core temperature. If you’re a hot sleeper, we recommend upgrading to the GlacioTex cover — the PCM makes a noticeable difference in how cool the surface feels.
Ease of movement was another highlight during our tests. Most of our testers encountered little resistance when moving across the surface, and the reinforced edges should help you get on and off the mattress with relative ease.
In addition to a below-average sticker price, the Midnight comes with two free pillows and ground delivery is free to the contiguous U.S. Your purchase includes a sleep trial that runs for 100 nights. If you decide to keep the mattress after the trial ends, you’ll also receive a 10-year warranty against premature sagging and other structural defects.

Product Details
Hybrids are one of the most popular mattress types on the market, but the average model costs at least $1,200 in a queen size and price is a barrier to many shoppers. The Brooklyn Bedding Signature Hybrid is an exception. The mattress features a relatively affordable yet high-quality design, and three different firmness options ensures both great support and wide appeal across different body types.
What It’s Made Of
The Signature Hybrid is available in medium soft (4), medium firm (6), and firm (8) options. All models begin with several layers of polyfoam, with the density and thickness of each layer varying between firmness options. The foams are adaptive, so you’ll notice some cushioning and contouring when you get into bed, but they’re also supportive enough to keep your body on an even plane and help prevent uncomfortable sinkage. Robust coils and dense base foam provide additional stability in all three models, and a cotton cover encases the mattress.
How It Performed
Based on heat gun readings during our temperature control tests, the cotton cover helps offset heat retention from the foam layers. Another cooling component is the coil system, which promotes steady airflow throughout to maintain a comfortable interior temperature. Pressure relief was a major testing highlight. The foam layers offer enough cradling to alleviate sore spots in the shoulders, hips, and other sensitive areas along the spine.
The mattress earned high ratings from most of our testing team. The medium soft model fared well with side and back sleepers up to 230 pounds, while the medium firm model performed best with side and back sleepers between 130 and 230 pounds. The firm option catered to back and stomach sleepers over 130 pounds.
In addition to its below-average pricing, the Signature Hybrid qualifies for free ground shipping throughout the contiguous U.S. Brooklyn Bedding’s sleep trial runs for 120 nights, and you may return the mattress for a full refund after sleeping on it for at least 30 nights. Should you decide to keep the bed, it’s further backed by a 10-year manufacturer’s warranty.
If you’re seeking a mattress with a luxurious feel and sturdy design, the Saatva HD won’t fail you. Responsive latex, a foam-quilted surface, and supportive coils give this bed a firm yet plush quality.

Product Details
An innerspring mattress with a firm (7) feel, the 15.5-inch Saatva HD is designed with heavy-duty elements engineered to support sleepers up to 500 pounds without compromising pressure relief. This is a strong option for shoppers who are willing to spend a little bit more money for a bed with superior support.
What It’s Made of
The Saatva HD has a breathable organic cotton cover certified by the Global Organic Textile Standard (GOTS). Quilted polyfoam adds extra padding with an integrated, hand-tufted Euro-top design. The comfort system also includes five-zone natural Talalay latex and memory foam. These layers contour to the sleeper and provide additional support to the lumbar area to help prevent pressure buildup.
The support core consists of a layer of thick 12.5-gauge innerspring coils. The coils feature a polyfoam encasement around the perimeter, allowing more usable surface area for sleepers. The layer also has a spinal zone wire for additional lumbar support.
How It Performed
The Saatva HD helps maintain spinal alignment for back and side sleepers over 130 pounds. It also supports stomach sleepers across all weight categories, and the combination of latex and springs helps facilitate movement.
This model stands out for its temperature neutrality. The latex is perforated with tiny holes to increase heat dissipation, and the innerspring support core allows air to flow freely.
The Saatva HD is available in the six standard mattress sizes as well as split king. Like Saatva’s other mattresses, the HD is delivered with complimentary White Glove delivery and old mattress removal. Saatva offers a lifetime warranty and a 365-night sleep trial, with a nominal $149 return fee to cover handling costs.

Product Details
Finding a mattress that doesn’t sag too much and also feels comfortable can be challenging, since less sagging is often associated with a firmer, stiffer feel. The Leesa Sapira Hybrid successfully toes that line thanks in part to its deep foam layers near the surface.
What It’s Made of
The Leesa Sapira Hybrid is constructed with a mixed-foam comfort system. The top layer consists of polyfoam that feels both adaptive and responsive, creating a light bounce as the material molds to your body. The polyfoam is perforated with channels to promote ventilation. A second comfort layer of medium-density memory foam provides additional contouring. Although the mattress is medium firm (6), both of these foam layers are fairly plush.
The mattress also contains a transitional layer of high-density polyfoam, followed by a pocketed coil system and another high-density foam layer for base-level support. The coils deliver strong stability with extra reinforcement along the edges. A knit polyester cover encases the entire mattress.
How It Performed
Most of our testers experienced little to no pressure buildup and received adequate support from the coil and base layers. The hybrid was particularly popular among our side sleepers weighing at least 130 pounds, and back and stomach sleepers under 130 pounds. Temperature control is another area where the Leesa Sapira Hybrid excelled during our hands-on tests. The ventilated polyfoam layer pushes air near the surface to keep you comfortable, while the coils circulate additional air to cool off the mattress interior. The knit cover is also breathable. None of our testers felt excessively hot lying on the mattress.
The Leesa Sapira Hybrid is priced competitively and shipping is free of charge for customers in all 50 states. Each order comes with a 100-night trial period and a standard manufacturer’s warranty that covers structural defects for up to 10 years.
Strong support is a must-have if you’re looking for beds that minimize back pain. The WinkBed Plus is a perfect candidate, due to its exceptionally firm feel and sturdy coils. Even better, the coils are zoned to boost support to your lower back.

Product Details
The WinkBed is available in four firmness options, but the WinkBed Plus caters specifically to sleepers who need enhanced support. We found the sturdiness of this hybrid model also makes it a great option for sleepers who need extra support to reduce back pain during sleep.
What It’s Made of
As a mattress designed for people who weigh more than 230 pounds, the WinkBed Plus begins with a top layer of high-density polyfoam and a second layer of zoned latex. Both of these materials are highly responsive, adding extra bounce to the surface and reinforcing the firm (8) feel. A Euro-top surface adds some plushness for comfort without sacrificing the Plus’s supportive qualities.
The support core contains 7.5-inch pocketed coils in a zoned arrangement. Thicker coils lie beneath the midsection to provide push-back and prevent sagging around the sleeper’s heaviest areas. The coils are also bolstered along the perimeter to reduce sinkage when you lie near or sit along the edges. A cover made of breathable, moisture-wicking Tencel fabric encases the mattress.
How It Performed
The WinkBed Plus performed well across the board during our hands-on tests – no small feat for a mattress this firm. The testers who felt most comfortable were those weighing more than 230 pounds, but the Plus also fared better than expected with lighter sleepers. This was especially true of testers who primarily use the back and stomach positions.
The latex retains very little heat, air flows freely through the coils, and the Tencel cover is both breathable and absorbent. As a result, the Plus is a great choice for people who frequently sleep hot or sweat in bed. The zoned coils also provide excellent push-back to ensure little to no sinkage around the torso and hips, as well as superior perimeter protection.
WinkBeds offers free ground shipping throughout the contiguous U.S. Each order comes with a 120-night trial. If you find the Plus too firm, you may exchange the mattress for a model with a different firmness level at no extra charge. WinkBeds are backed by lifetime warranties.

Product Details
When choosing a new mattress, we recommend taking your sleep position into account. Side sleepers generally need a softer mattress that provides extra cushioning for their downward-facing shoulder and hip. The Nolah Evolution 15 is a hybrid mattress available in three firmness levels, allowing you to choose a support system based on your body type. All three models offer plenty of padding for side sleepers, and members of our testing team who primarily use this position awarded very favorable ratings to the Evolution 15.
What It’s Made of
The Evolution 15’s comfort system features a Euro-top containing four individual foam layers. Each layer is progressively denser from top to bottom, so you’ll notice some plushness when you get into bed and a cradling feel as your body settles. All four foams have an open-cell composition, so bothersome heat retention shouldn’t be a major issue. A graphite gel infusion in the second layer delivers additional cooling.
The support core consists of pocketed coils in a zoned arrangement. Thicker coils push back against the extra weight in your chest, stomach, and hips, while thinner coils create a gentler feel for lighter areas of your body. Extra perimeter reinforcement also means the mattress won’t sag when you lie or sit along the edges. The Evolution 15’s cover is made of organic cotton woven with cooling ArcticTex fabric.
How It Performed
Our team tested each of the Evolution 15’s three firmness levels. The medium (5) feel was most comfortable for our side sleepers weighing up to 230 pounds, and back sleepers under 130 pounds. At the other end of the spectrum, the firm (8) model provided adequate support for our back and stomach sleepers weighing at least 130 pounds. If you’re looking for something in the middle, we recommend the medium firm (6) design.
Temperature control proved to be a major strength of the mattress during our tests. We detected little to no heat buildup on the medium firm and firm models. While the medium design absorbed slightly more heat, none of our team members felt uncomfortably warm. Our testers also found that the Evolution 15 isolates motion and alleviates pressure better than the average hybrid mattress. We attribute these qualities to the deep, multi-layer foam comfort system.
Nolah offers free ground shipping throughout the contiguous U.S. and you’ll receive a pair of pillows with your mattress order at no extra cost. The Evolution 15 comes with a 120-night sleep trial, but you can opt out of the trial and cut your up-front costs by as much as $150. The standard manufacturer’s warranty covers structural defects for as long as you retain original ownership. You may purchase additional coverage for stains and spills for 10 years.

The Titan Plus is one of the firmest hybrid models we’ve tested firsthand. Rating as an 8 on our 10-point firmness scale, the mattress feels exceptionally supportive and maintains a flat, even surface for most people – even those weighing more than 230 pounds.
What It’s Made Of
The Titan Firm Hybrid is one of the firmest hybrid models we’ve tested firsthand. Rating as an 8 on our 10-point firmness scale, the mattress feels exceptionally supportive and maintains a flat, even surface for most people – even those weighing more than 230 pounds. A thin layer of memory foam is quilted into the cover, followed by 2 inches of dense polyfoam. These materials provide light cushioning. The support core consists of thick pocketed coils over a base layer of high-density polyfoam.
We found that the Titan Firm Hybrid sleeps reasonably cool. If you are a hot sleeper, you can opt to include a phase change material (PCM) panel sewn into the cover. PCM is engineered to capture and release body heat on contact, creating a surface that feels cool at all times. Measuring 11 inches thick, the Titan Firm Hybrid is considered a medium-profile mattress.
How It Performed
As a relatively firm mattress, the Titan Firm Hybrid performed well in areas where softer, more adaptive hybrids tend to struggle. These include temperature control, ease of movement, and edge support. Our tester encountered little resistance moving across the surface, and no one sank excessively when positioned near or along the perimeter. The cooling panel makes a noticeable difference to the surface temperature, but we also found the mattress comfortable without the panel.
During our hands-on tests, we found the Titan Firm Hybrid best suited to people over 230 pounds across the side, back, and stomach sleeping positions. The mattress offers plenty of support, which sleepers in this weight range often need. Back and stomach sleepers between 130 and 230 pounds also found the mattress comfortable.
The Titan Firm Hybrid is available in seven sizes, including a split king for couples who share adjustable beds. The price-point falls well below average for a hybrid and shipping is free throughout the contiguous U.S. Your purchase comes with a 120-night sleep trial, and you’ll also receive a 10-year manufacturer’s warranty if you decide to keep the mattress.

If you’re shopping for a new mattress with a partner, you’ll need to take a few extra considerations into account. The Bear Elite Hybrid performed well in all testing categories associated with couples. Findings include consistent motion isolation, a sturdy perimeter, excellent temperature control, and good bounce for sex.
What It’s Made Of
The Elite Hybrid’s comfort system contains memory foam over transitional polyfoam. A cooling gel infusion in the top layer helps dissipate heat and keep you cool, while the transitional foam is divided into five firmness zones based on where most of your weight is concentrated. This helps ensure pushback for the torso and hips, and a gentler feel beneath lighter areas of your body such as the head and legs. The support core consists of pocketed coils and high-density base foam. Thicker coils around the perimeter help strengthen the edges, allowing you and your partner to use the entire surface for sleep and sex.
A cover made with Celliant fabric encases the mattress. Celliant is engineered to capture and release heat on contact, maintaining a cool-to-the-touch feel at all times. You can choose from medium (5), medium firm (6), and firm (8) feels for your Elite Hybrid. The mattress is also available in seven sizes, including a split king for couples who use king size adjustable beds. If you fall into that category, Bear allows you to choose a different firmness level for each side of the mattress.
How It Performed
We tested all three of the Elite Hybrid’s firmness levels. The medium feel earned favorable ratings from side and back sleepers up to 230 pounds, but this model may be too soft for some. Those seeking extra support should consider the firm design, which was popular among our side sleepers over 230 pounds, and our back and stomach sleepers of at least 130 pounds. The medium firm proved to be the most balanced option, and received positive ratings from side and back sleepers across all weight groups.
Cooling is a major strength of this mattress. The cooling cover, gel-infused foam layer, and air-circulating coils work together to regulate your temperature and keep you comfortable throughout the year. The medium and medium firm models performed well during our pressure relief and motion isolation tests, while the firm model earned higher marks for edge support and ease of movement.
The Elite Hybrid is competitively priced and ground delivery is free throughout the contiguous U.S. Each order includes two pillows at no extra cost. Bear’s sleep trial spans 120 nights in length, and includes free shipping on returns. Those who keep their mattress receive a lifetime warranty covering various defects as long as they retain original ownership. An accidental protection plan against stains and other types of physical damage is available for an additional fee.

Product Details
If you share your sleep surface with a partner, both of your needs and preferences should influence your decision when shopping for a new mattress. Emma’s Hybrid Cooling Elite checks a lot of important boxes for couples thanks to its cushy-yet-supportive design. Foam comfort layers absorb movement and isolate motion well but shouldn’t trap too much heat, while the pocketed coil support core promotes airflow and stabilizes the perimeter. A medium firm (6) feel adds to the appeal of this balanced design.
What It’s Made of
The Hybrid Cooling Elite’s comfort system contains four individual layers, beginning with plush adaptive polyfoam. A graphite infusion in this layer is intended to dissipate heat from your sleep surface. Underlying polyfoam and memory foam layers are a bit denser to keep your body on an even plane, but they also provide extra cushioning. Transitional polyfoam creates a nice buffer between you and the support core.
The pocketed coils are arranged in seven zones based on strength. Thicker springs rest beneath your torso and hips for extra reinforcement, since these areas of the body tend to carry more weight, while the coils under your head and legs provide a gentler feel. A thick layer of high-density base foam provides additional stability, and the entire mattress is encased on a knit polyester cover.
How It Performed
Most of our testing team felt comfortable and sufficiently supported when lying on the Emma Hybrid Cooling Elite. Side sleepers weighing at least 130 pounds, back sleepers up to 230 pounds, and stomach sleepers under 130 pounds were particularly impressed. The zoned coils are a major asset. By delivering targeted support for the entire body, the mattress minimizes sinkage and reduces the likelihood of pain or pressure buildup in sensitive areas.
We found motion isolation and pressure relief to be two major strengths of the hybrid, and strong performance in both areas can be attributed to the thick foam layers in its comfort system. Temperature control is another standout quality. The foam layers don’t absorb much heat thanks to their open-cell composition, and air flows freely through the coil layers. You may notice some strong off-gassing odor after the mattress is unboxed, but these smells should dissipate in a couple of days.
The Hybrid Cooling Elite carries a below-average sticker price and standard shipping is free for all U.S. customers. Emma’s generous sleep trial allows you to test the mattress in your home for up to one. Full refunds are issued for those who return the hybrid during this time frame, but you’ll receive a lifetime warranty if you decide to keep it.

Product Details
Hot sleeping is all too common, and anyone who overheats in bed should consider a mattress with cooling components. The Birch Mattress is constructed top to bottom with temperature-regulating materials, and its medium firm (6) hybrid design also helps ensure above-average durability and little to no sagging over the course of its lifespan. Latex’s naturally springy feel is a great alternative if you want a mattress that cushions your body without the “hugging” sensation of sleeping on memory foam.
What It’s Made Of
The mattress begins with an organic cotton cover and wool fire barrier. Cotton is naturally breathable and the wool has moisture-wicking properties, allowing the Birch to maintain a cool, comfortable surface throughout the year — even on exceptionally hot or humid nights. The latex comfort layer gently contours to cradle your sore spots, but you’ll notice a significant bounce before your body settles. This bounciness helps you move across the surface without sinking.
Pocketed coils and a base layer of wool/rayon fiber batting make up the support core. The coils are thicker along the perimeter, so you should feel secure sleeping near the mattress’ edges and won’t sink too much when getting in and out of bed.
How It Performed
The Birch earned widespread praise from our testing team. Its most favorable ratings came from side sleepers weighing at least 130 pounds, and back and stomach sleepers weighing up to 230 pounds. We were particularly impressed with the Birch’s balance of surface-level cushioning, robust base support, and subtle bounce.
Our edge support tests confirm sufficient pushback along the perimeter. Temperature control was another testing highlight. Our thermal mapping technology revealed very little heat buildup, and none of our testers felt excessively warm lying on the mattress. The responsive latex also allowed us to move across the surface without sinking too much.
The Birch Mattress is competitively priced, shipping is free to customers in all 50 states, and you’ll receive two free pillows at no extra cost. Your order comes with a sleep trial running 100 nights in length. You may return the mattress free of charge during this time frame. If you’re satisfied with your purchase, a 25-year warranty against structural defects kicks in once the trial period ends.
Data-Driven Results You Can Trust
Finding a mattress that will stand the test of time can be a challenging task, especially since many newer manufacturers don’t yet have a proven track record. Our experts are well-versed in mattress construction, and our vast experience has helped us learn how to identify well-built designs with a long-expected lifespan.
We back our recommendations with an extensive testing process during which we analyze every facet of the mattress, including how it performs for people with different body types and preferred sleep positions. Because sleepers over 230 pounds exert more pressure on mattresses, our team incorporates sleepers in this weight range as well.

What Causes a Mattress to Sag?
Over time, foam breaks down and coils lose their ability to spring back to their original shape. Both of these issues can result in sagging. Most mattresses will sag eventually, but the quality of construction and materials can accelerate or delay the occurrence.
Premature Sagging vs. Normal Wear and Tear
There are two primary components to a mattress: the comfort system and the support core. Ultimately, every layer of the mattress affects its propensity to sag. The comfort system is more prone to localized body indentations, whereas the support core can cause broader structural problems.
Support Core: The support core is usually made of sturdy materials such as steel springs or high-density polyfoam, which are designed to withstand repeated use before they start breaking down.
Mattresses with low coil counts or low-quality steel are quicker to lose their elasticity, and they generally sag sooner than higher-quality builds. A hybrid mattress made with low-quality coils may only last 5 to 6 years, whereas a better-quality base may lengthen the expected lifespan up to 8 or 10 years.
Likewise, low-density polyfoam with thinner cell walls and more air pockets is more susceptible to sagging. Lower quality all-foam models can break down as soon as 2 or 3 years after purchasing, whereas better models may last up to 7 or 8 years.
Comfort System: The comfort system tends to include softer materials such as memory foam, which can break down sooner and develop permanent indentations. Additionally, mattresses with thicker comfort sections may be more vulnerable to forming body impressions. To a certain extent, this wear and tear is considered a normal part of mattress use. Sometimes, manufacturers add firmer transitional layers to reinforce the softer layers on top.
Most manufacturers don’t cover sagging and body indentations under warranty unless they reach a certain level, such as 1-inch indentations that are visible even when no pressure is applied. If your mattress has body impressions that are not covered by the warranty and you find they affect the mattress’ ability to provide pressure relief, you may be able to compensate by using a mattress topper.
Although the warranty length and terms do not always correspond to the quality of the mattress, these can be a good indication of how long the manufacturer expects the bed to last. Warranties that cover body impressions of at least 1 inch — as opposed to impressions of 1.5 or 2 inches — indicate that the construction will likely prevent premature sagging.
Similarly, longer warranties of 15 or 20 years imply that the mattress may last longer before needing to be replaced. These models are often more expensive up-front, but the price may be worthwhile if it saves you the cost of buying another new mattress within that time frame.
How to Choose a Durable Mattress
There are several indications that hint at when a mattress may start sagging, such as the price, the type of materials, and the firmness level. When purchasing a mattress, you should also consider factors that influence the overall comfort, such as temperature regulation and motion isolation, as well as whether the mattress design is appropriate for your body type and sleeping position.
What to Look For in a Mattress That Won’t Sag
Mattress shopping can be overwhelming, as every manufacturer has its own terms to describe proprietary materials. Understanding how the different mattress components contribute to its overall feel and performance can help you narrow down your choices and find a bed suitable for your needs.
Price
Mattress price is an easy way to weed out low-quality mattresses. While prices can vary according to brand, special features, or organic certifications, a cheap mattress will generally sag sooner. These beds may be suitable for guest rooms, but they likely aren’t designed to withstand regular use.
Sleeping Position
Proper spinal support is important no matter what sleeping position you prefer. However, a sagging mattress may be most uncomfortable for stomach sleepers if it allows the midsection to sink in too much. Back sleepers also require a reliable surface to support the lumbar spine.
Quality Materials
Mattresses built with natural materials such as latex and wool tend to outlast other materials. When assessing the quality of your mattress, note the coil count, the coil gauge or thickness, the foam density, and any vulnerable points that may be more susceptible to premature sagging, such as convoluted polyfoam. Look for manufacturers that are transparent with their specs.
Firmness Level
The right firmness level for you depends on your body weight and primary sleep position. Broadly speaking, firmer mattresses tend to be more resistant to body impressions, although there are many exceptions as this also depends on the materials used. Stomach sleepers and individuals who weigh more than 230 pounds may find that a firm (7) or extra firm (9) mattress offers longer-lasting support.
Pressure Relief
Pressure relief is a key factor for all sleepers, especially for side sleepers and those who weigh under 130 pounds. These sleepers can experience pressure points where the hips and shoulders make contact with the mattress, so they benefit from having cushioning materials in the comfort system. High-density memory foam, natural Talalay latex, and wool are examples of pressure-relieving materials with a long-expected lifespan.
Motion Isolation
For people who sleep with a partner, it’s important to find a mattress that doesn’t transfer motion across the bed. All-foam models and hybrids with individually wrapped coils tend to perform well at motion isolation.
Temperature Regulation
Temperature neutrality is especially relevant to hot sleepers and those who live in warm climates. Mattress manufacturers use many techniques to fight against heat retention. For example, mattresses can include moisture-wicking covers, and foams may be perforated or infused with gel beads designed to draw heat away from the bed’s surface. Innerspring cores also perform well at temperature neutrality, as their construction allows air to flow freely through the coils.
Edge Support
Whereas hybrid and innerspring models usually feature a reinforced perimeter, foam and latex models may compress significantly when weight is placed on the edges of the bed. Weak edge support can significantly limit the usable surface area, so it’s an important consideration for people who like to sit on the edges, partners who share a smaller bed, or those who have trouble getting in and out of bed. Foam mattresses may break down sooner, so if you value edge support, consider a bed with a firmer, thinner comfort system.
Contouring
Contouring refers to a material’s ability to mold itself to the sleeper. Mattresses that contour more closely tend to provide better pressure relief, but they may be more apt to develop body impressions over time. Ideally, the comfort system should provide a certain level of contouring, while the transition layers and support core help bolster spinal support and enhance durability.
Mattress Type
Mattresses are classified into different types according to the primary materials used in their construction. While every model is unique, the mattress type plays a significant role in its performance and durability. Latex and hybrid mattresses often outperform foam and innerspring models when it comes to durability.
Mattress Types
The primary mattress types include hybrid, innerspring, foam, latex, and airbed. Mattress type is mainly determined by the materials used in the support core. While a mattress type can describe general characteristics, there can also be variations from model to model depending on the design and the quality of the materials.
Hybrid
Hybrid mattresses combine a substantial comfort system with an innerspring core, which is typically made with pocketed coils to reduce noise and motion transfer. The comfort layers may incorporate polyfoam, memory foam, latex, wool, cotton batting, microcoils, or other pressure-relieving materials.
Hybrid mattresses offer better pressure relief than classic innerspring models, and they also tend to boast sturdy edge support and strong breathability due to the coil layer. This makes them ideal for hot sleepers and those who enjoy using the full surface of the bed.
When looking for a hybrid mattress that won’t sag, aim for a minimum of 1,000 coils in a queen size and dedicated reinforcement around the perimeter. In the comfort system, high-density foams or natural materials like wool or latex are usually the most durable.
Innerspring
Sleepers who favor bounce, edge support, and airflow may be interested in an innerspring model. This mattress type is made almost exclusively of tempered steel coils, with little to no comfort system. These features make innerspring mattresses suitable for stomach sleepers but less suitable for side and back sleepers.
The durability of an innerspring mattress can vary greatly depending on the type, the gauge, and the total number of coils. Thicker-gauge coils and designs such as offset coils can withstand more pressure without losing their resilience. By contrast, older designs such as Bonnell coils may start sinking sooner.
It’s good practice to ensure your mattress has an appropriate coil count for the type of coils used, though several other factors influence a mattress’ performance. Similarly, coils may have different functions depending on their gauge and placement in the mattress. Many manufacturers use thicker low-gauge coils to strengthen the edges and thinner high-gauge coils for the hips and shoulders.
Foam
Foam mattresses contain polyfoam, memory foam, latex, or textiles in the comfort system and sit above a polyfoam support core. Ideally, the support core uses durable high-density polyfoam with a density of at least 1.8 pounds per cubic foot (PCF).
Couples often prefer foam mattresses because the lack of springs allow less motion to transfer to the other side of the bed when one person moves. Models with memory foam in the comfort layers also offer unparalleled pressure relief for side sleepers and individuals under 130 pounds. Sleepers over 230 pounds, however, may find that foam mattresses lack sufficient support.
In addition to the foam density and quality of the materials used, the thickness of the comfort system can also affect a mattress’ lifespan. Thicker comfort systems are more likely to develop body impressions, especially if they are made with low-quality materials.
Latex
Natural latex is made from sap found in rubber trees, which is whipped into a froth and baked using either the Dunlop or the Talalay process. Dunlop latex tends to be denser on one side, whereas Talalay is more buoyant and uniform. Latex can also be made synthetically using petrochemicals.
Natural latex is considered one of the most durable mattress materials, making it highly resistant to sagging. It can be used in the comfort or support layers, and it is often aerated with pincore holes to improve breathability. Mattresses made with certified organic latex may be appealing to sustainably minded shoppers.
Airbed
Airbeds use air chambers as the support core, which can often be inflated or deflated by the user until they reach the desired firmness level. Provided there are no leaks in the air chambers, this system should be protective against sagging as more air can always be added to increase the firmness setting.
Sleepers who want adjustable firmness levels or couples with differing comfort preferences may be interested in an airbed, as each side of the bed generally includes its own customizable air chambers. Airbeds may have additional layers of polyfoam, memory foam, or other materials to supplement the air chambers as well.
Extending the Lifespan of Your Mattress
By adopting a few proactive habits, you can help keep your mattress in tip-top shape for a longer period of time and delay when you need to invest in a new one.
Use a Mattress Protector and Clean Regularly
A mattress protector is a thin, waterproof membrane designed to protect your mattress against spills and stains. Not only does this help prevent accidental damage to your mattress, it can also prevent you from inadvertently voiding your mattress warranty, as most manufacturers won’t cover mattresses with visible stains.
Rotate Your Mattress
Most mattresses sold today aren’t designed to be flipped. However, you can delay the onset of permanent body impressions by rotating the mattress head-to-foot every 3 to 6 months.
Use Proper Support Under The Mattress
A proper foundation is essential for keeping your mattress supported and preventing pressure points from improper spinal alignment. Consult the manufacturer’s website or the warranty terms to find out what type of base is recommended for your model. Generally, a solid or a slatted foundation will offer sufficient support. You may need to ensure the slats are close enough together to prevent sagging. A full mattress or larger may require additional support in the center of the bed.
Frequently Asked Questions
Gel mattresses aim to offer a cooler sleep experience, which can raise the price-point compared to regular foam mattresses. Gel foam is a good option for sleepers who like the pressure-relieving, motion-isolating feel of memory foam or polyfoam but don’t like sleeping hot.
Because gel must be added to either memory foam or polyfoam, gel mattresses may not be attractive to shoppers who prefer natural materials or those who are sensitive to off-gassing smells.
As gel foam is meant to be used in the comfort layers, gel mattresses can come in either hybrid or all-foam models. All-foam models have a high-density polyfoam support base, whereas hybrid mattresses have an innerspring base that is often made with pocketed coils. More rarely, shoppers might see airbed models with gel foam comfort layers over an inflatable air chamber.
The average price of a gel mattress runs from about $800 to $2,000, though there are plenty of models that fall outside of this range. Foam mattresses are among the cheapest options, while hybrids may be more expensive. Although gel foam is more expensive than regular memory foam or polyfoam, gel mattresses usually cost less than natural latex mattresses.
Pricing can change depending on the brand, the design of the mattress, the quality of the materials, and the shipping and return policies. If you want the feel of gel foam but not the investment in a new mattress, a gel foam mattress topper may also be an option.
On average, buyers can expect a foam or hybrid mattress to last 6 to 8 years if properly cared for.
With all mattresses, the comfort system generally starts to break down before the support core. As a comfort layer, gel foam is not the most durable material, especially in its plusher iterations. However, regularly rotating the mattress from head to foot can delay the onset of permanent body indentations. Using a mattress protector can also help extend the lifespan by shielding the material against accidents.
