Best Duvet Inserts of 2024

The Brooklinen Down Comforter is made in Canada using ethically sourced down harvested from Europe and Canada. With premium, high-quality materials and multiple warmth options, the Brooklinen is an excellent and highly comfortable pick for a wide variety of sleepers who prefer down.

Made with 100% down cluster fill, the Brooklinen has all of the best features of a down-based duvet including cloud-like loft and incredible insulation power. The fill material is treated with an antimicrobial to help prevent the growth of bacteria or mold and keep your bedding fresh. The outer shell of the Brooklinen is made with soft and breathable 100% long-staple cotton sateen.

The Brooklinen also comes in more than one weight. The all-season weight is made with 700 fill power down that’s extremely warm and lofty. However, for those who sleep warm or live in a slightly warmer climate, the lightweight option contains a 650 fill power down that’s a bit cooler. The ultra-warm weight is constructed with 750 fill power to keep sleepers warm on colder nights.

The insert is designed with baffle box construction to keep the down fill in place. Loops are sewn into every corner to act as tie-in points for a duvet cover.

Brooklinen recommends spot cleaning stains. You should also periodically hang your down duvet outside on a dry day or use a dryer on the no-heat setting to dry it out. Brooklinen provides one of the most generous return policies in the industry. Most products can be returned or exchanged within 365 days for free with a full refund. Shipping is free for customers in the contiguous U.S.

The Quince Premium Down Alternative Comforter is a reasonably priced duvet insert that comes in two weight options for varying levels of warmth. Both offer a cozy feel with strong insulation that won’t trap heat excessively.

The comforter is filled with a down alternative microfiber that mimics the lofty feel of down. The shell is composed of breathable cotton in a smooth sateen weave. You can choose between an all-season or lightweight option. The latter is suitable for spring or summer months — or year-round in warmer climates — while the all-season option features a heavier design that provides strong insulation in cooler months. That said, the microfiber fill has a lightweight feel that should prevent bothersome heat retention for many sleepers.

The Quince Premium Down Alternative Comforter is sewn with baffle boxes to evenly distribute the fill and help keep it from bunching up during the night. You may use corner loops to secure the insert to your duvet cover. The comforter is machine-washable in cold water on a gentle cycle, and you may tumble dry it on low heat. However, dry cleaning may be a better option if your home machines are too small to accommodate bulky bedding.

Quince offers free shipping and a 365-night sleep trial with this comforter.

A duvet insert that effectively regulates temperature based on the current conditions is key if you are an exceptionally hot or cold sleeper. With the Silk & Snow Down Alternative Duvet Insert, you get the best of both worlds at an approachable price. Plush down alternative fill retains minimal heat, and the cotton shell promotes breathability. You shouldn’t feel uncomfortable on hot or humid nights, but the insert is cozy and lofty enough to keep you warm during chillier times of the year. As an added bonus for people allergic to real down, the fill is 100% animal-free and shouldn’t trigger any symptoms.

You can also choose from three different weights based on your personal preferences and local climate. The Lightweight design’s fill consists of 175 grams per square meter (GSM), so this insert is best suited to dry, arid areas and people who don’t need thick covers to sleep comfortably. If you’re looking for maximum heft, the Winter design contains 500 GSM of fill and insulates exceptionally well. The All-Season design with 375 GSM of fill is ideal if you want something in the middle, or if you live in a place with mild, temperate weather throughout the year.

The baffle boxes are sewn through, creating compartments to hold the fill and evenly distribute it across the insert. This minimizes clumping, so you shouldn’t have to fluff the insert too often. Corner loops also allow you to secure the insert to a duvet cover. We recommend using a cover because machine washing the insert can be a hassle — especially if your household washer is too small — and dry cleaning can be somewhat expensive.

Twin/twin XL, full/queen, and king/California king sizes are available. All three options are oversized to provide ample coverage for your sleep surface. Price depends on the size and weight you select. Silk & Snow offers free ground shipping for all orders in the contiguous U.S. and provincial Canada. Your purchase comes with a generous sleep trial that runs for 100 nights, and you’ll also receive a 1-year warranty if you decide to keep the Down Alternative Duvet Insert.

The Cozy Earth Bamboo Comforter is one of two comforter options available, both of which offer exceptional breathability. The bamboo version is composed entirely of viscose derived from bamboo, a material touted for its luxuriously soft feel that can soothe sensitive skin. All of Cozy Earth’s products are made from sustainably sourced materials, making the comforter a great choice if you’re willing to spend more on an eco-friendly product.

Bamboo-derived fabrics are known for their cooling and moisture-wicking properties that cater to hot sleepers and people living in warm or humid locations. You can also opt for a silk version of the comforter for a fluffier, down-like feel. Both the bamboo and silk models come in two fill volume options: standard and extra. The standard option is lightweight but insulates a comfortable amount of warmth, so we recommend it for year-round use. The extra weight is excellent for winter use or if you live in a cooler climate.

The comforter is fully machine-washable. Cozy Earth recommends only using a rinse cycle and drying on low heat with a few tennis balls to prevent the fill from clumping. Three sizes are available – twin, queen/full, and king – and all are intentionally oversized to fit most mattresses.

If you live in the contiguous U.S, you’re eligible for free shipping. Cozy Earth offers a 100-night sleep trial with your comforter purchase, during which you can return it for a full refund. The Bamboo Comforter is backed by a 10-year warranty against structural defects.

The Company Store Legends Hotel Organic Cotton, Down Comforter has a billowy feel and crisp appearance that cater to sleepers who are on the hunt for a comforter that matches the quality and design of luxurious hotel bedding.

The comforter contains European white down with 600 to 650 fill power, which produces a cozy and lofty feel. The down has Responsible Down Standard (RDS) certification to help ensure ethical sourcing. The fill is encased in a shell made of organic cotton with a 230 thread count. Baffle-box stitching helps distribute the fill evenly while also preventing clumping, and corner loops can be attached to your duvet cover to keep the comforter from bunching up.

You can choose from four warmth levels to suit your temperature preferences or climate. The warmth levels are light, medium, extra, and ultra. The comforter is available in four size options — twin, full, queen, and king/California king. The Company Store recommends dry cleaning for proper maintenance.

The comforter qualifies for free shipping to the contiguous U.S. You may return the comforter within 30 days.

Saatva’s All-Year Down Alternative Comforter lives up to its name thanks to a design that’s suited to any season. The fill blend of down alternative clusters and lyocell fibers strikes a nice balance of insulation and breathability. Lightweight construction means the comforter won’t feel too hefty on hot or humid nights, but you’ll get the warmth you need when the temperature is low.

A quilted shell composed of pure cotton encases the fill. Each baffle box is sewn through to contain and evenly distribute the fill, so you won’t need to fluff the comforter too frequently or deal with clumping during the night. Corner loops let you secure the comforter to a duvet cover.

Twin/twin XL, full/queen, and king/California king sizes are available. Although the comforter is machine-washable, your household appliances may not be large enough to accommodate it — especially if you opt for a larger size. Dry cleaning is an alternative care method.

The All-Year Down Alternative Comforter’s sticker price is somewhat steep, but Saatva offers free ground shipping throughout the contiguous U.S. You can test the comforter at home for up to 45 nights before deciding whether to return it for a refund or keep it. If you go with the latter, your purchase is further backed by a one-year manufacturer’s warranty.

Most duvet inserts are on the softer side, but Avocado’s Down Duvet Insert elevates this quality even further with a fill composed of pure down clusters. You can choose between two weights — a light option best suited to hot and humid weather or an all-season insert for year-round use — but both feel exceptionally lightweight and lofty. A soft, quilted cotton shell adds to the timeless design.

Baffle-box construction helps evenly distribute the down, so there shouldn’t be much clumping or shifting during the night, and subtle piping along the perimeter helps protect the shell from rips and tears. Each corner has a loop for securing the insert to a duvet cover. Full/queen and king/California king sizes are available. The lightweight insert weighs 20 to 24 ounces, while the all-season insert weighs 24 to 28 ounces. Avocado recommends spot cleaning the shell if stains or smudges occur. The insert should not be machine-washed or dry cleaned.

A certification from the Responsible Down Standard indicates Avocado adheres to humane and ethical standards for animal treatment. The company is also climate neutral, meaning all carbon emissions are offset through sustainable manufacturing and shipping practices. Standard delivery is free of charge for customers in the contiguous U.S. All orders include a 100-night sleep trial and one-year warranty.

Boll & Branch’s Down Alternative Duvet Insert offers a comfortable balance of cooling and insulation, allowing you to stay warm during chilly times of the year without overheating when temperatures rise. You can choose from lightweight, midweight, and heavyweight designs based on your local climate and personal preferences as a sleeper.

PrimaLoft down alternative cluster fill creates a plush, lofty feel, but — unlike natural down — it isn’t made using animal-based materials and won’t trigger any allergy symptoms. A quilted design with sewn-through baffle boxes helps ensure the fill is evenly distributed throughout the interior, and a loop at each corner lets you secure the insert to a duvet cover. The shell is made of soft, breathable organic cotton.

The insert is machine-washable. That said, most washing machines with agitators are too small to accommodate it. The good news is that you should only need to launder the insert every three to six months, and dry cleaning is an alternative care option to visiting the laundromat. Full/queen and king/California king sizes are available. Both have oversized dimensions to provide plenty of coverage for you and your partner.

The Down Alternative Duvet Insert is on the expensive side compared to the competition, but shipping is free within the contiguous U.S. Boll & Branch allows you to return the insert for a refund or exchange it for a different weight within 30 days of receipt.

As many couples can attest, some comforters and duvet inserts don’t provide enough coverage for two people. The Luxome ClimaSense Comforter is specifically designed with co-sleepers in mind. You can choose from full/queen or king/California king inserts, both of which are oversized to cover the entire sleep surface and drape over the sides of your mattress.

The comforter is packed with down alternative clusters to create an exceptionally plush and cozy feel. Each baffle box is sewn through to prevent excessive clumping or shifting. A shell made from a blend of cotton and polyester encases the fill. This fabric is highly breathable and resistant to heat buildup.

The comforter should not be machine washed. We recommend investing in a cover to keep your sleep surface hygienic. Luxome also sells a matching cover composed of viscose derived from bamboo. If you bundle your purchase with both items, you’ll receive a discount on the cover. Standard shipping is free within the contiguous U.S., and Luxome backs each comforter with a 30-night trial.

Most people associate comforters with chilly nights, but the Buffy Breeze proves they can be equally suited to hot and humid conditions. The Breeze’s shell and fiber fill are both composed of Tencel, a eucalyptus-derived textile prized for its cooling and moisture-wicking properties. A lightweight design and luxuriously soft feel add to the comfortable all-season design.

Quilting with wavy baffles helps contain and evenly distribute the fill, so you shouldn’t need to fluff the Breeze too often. Each corner features a loop for securing the insert to a duvet cover. Buffy recommends dry cleaning the Breeze if needed, but a cover should provide some protection against stains and smudges. Twin/twin XL, full/queen, and king/California king sizes are available. All are oversized to provide plenty of coverage, whether you normally sleep alone or with a partner.

The Breeze is completely biodegradable and compostable, which should appeal to eco-conscious shoppers. Although the sticker price is somewhat high, Buffy offers free shipping throughout the contiguous U.S. and each customer can test the comforter for up to one week before their credit card is charged. Returns may be initiated within 50 days of the original purchase date.
