The OkiFlex isolates motion well due to its memory foam comfort layer and the foam-encasement surrounding its pocketed coils. Most sleepers will not be bothered by motion transferring across the surface of the mattress when a sleep partner moves around or gets in or out of bed.
All-foam mattresses tend to isolate motion even better than hybrid mattresses that contain foam comfort layers, such as the OkiFlex. Sleepers who are hyper-sensitive to motion on the mattress might want to opt for a memory foam mattress instead.
Innerspring mattresses isolate the least motion because their coils are all connected to each other, unlike pocketed coils. Hybrids such as the OkiFlex transfer less motion than most innerspring beds do.

Pros & Cons:

Below-average price point, so great option for shoppers on a budget

365-night sleep trial to ensure the mattress is for you
-
Side sleepers weighing under 130 pounds might find that this mattress feels too firm.
The OkiFlex Mattress is one of two hybrid mattresses sold by OkiOki. The company sells four mattress models: the OkiFlex, the OkiEasy, the OkiSoft, and the OkiFirm. The OkiFlex and OkiEasy are both coil and foam hybrids. The OkiSoft and OkiFirm beds are both memory foam mattresses.
All four OkiOki Mattresses are priced identically. Aside from construction materials, the primary differentiating factor among the mattresses is firmness. Of the memory foam beds, the OkiSoft (medium) rates softer than the OkiFirm (firm). Of the hybrid beds, the OkiEasy (medium-firm) rates softer than the OkiFlex (firm).
The OkiFlex Mattress features a layer of graphite-infused memory foam, a transition polyfoam layer, pocketed coils, and a small amount of base polyfoam. Together, these layers provide sleepers a firm yet pressure-relieving feel.
OkiOki offers an unusually generous 365-night sleep trial, which means customers can return their mattress at any point within the first year after purchase. The OkiOki Mattresses are sold at below-average price-points, making them more affordable to more customers.
This guide focuses on how the OkiFlex Mattress performs for people of different weight groups and sleep position preferences. The guide also contains information about OkiOki’s sleep trial, warranty, shipping, and return policies.

Side Sleepers
Some side sleepers, particularly those weighing over 130 pounds, find comfort on the OkiFlex Mattress. The transition layer helps promote spinal alignment for side sleepers. This layer allows the heavier hips and shoulders to sink into the mattress more deeply while still supporting the abdomen.
That said, OkiOki specifies that the OkiFlex bed performs best for stomach and back sleepers. Generally, stomach and back sleepers require firmer mattresses since they are capable of adequately supporting the body in those positions. Some side sleepers might prefer a mattress specifically designed for their needs.
Side sleepers weighing under 130 pounds tend to find the OkiFlex feels too firm. In this group, lying on the mattress could lead to the development of pressure points. When a side sleeper lies on a mattress that is too firm for their body, they tend to experience pressure in their neck and lower back.
Back Sleepers
All back sleepers find comfort in the OkiFlex, but back sleepers weighing over 130 pounds enjoy the mattress the most. This group finds adequate lumbar support in the bed. They experience pressure relief and a nice mixture of comfort and support.
The OkiFlex Mattress is specifically marketed as being ideal for back sleepers. Its firmer feel provides lumbar support to back sleepers of all weights. On the OkiOki website, many reviewers have commented that they experience less back pain as a result of sleeping on this mattress.
When a mattress is too soft, back sleepers tend to experience pressure and discomfort in the lower back. A firmer mattress helps keep the back from arching too much and prevents the lower body from sinking in too deeply to the support core.
Stomach Sleepers
The OkiFlex provides excellent support to stomach sleepers weighing between 130 and 230 pounds. This group of sleepers find that the firmness of the bed helps them to maintain spinal alignment. Softer mattresses tend to allow stomach sleepers’ bodies to sink in more deeply, which can put strain on the neck and cause discomfort.
Stomach sleepers of all weights find comfort in the OkiFlex Mattress. OkiOki markets this bed as one that’s specifically made for stomach and back sleepers due to its increased firmness level.
Some heavier stomach sleepers weighing over 230 pounds might want an even firmer mattress to help them feel more supported. Most stomach sleepers will find the firmness level of the OkiFlex adequate, however. Personal preferences about a mattress’s firmness or softness also factor into whether or not a sleeper enjoys the OkiFlex Mattress.

OkiFlex Mattress Review Breakdown
The OkiFlex Mattress is a hybrid mattress featuring foam and coil layers. The bed measures firm, or 7 out of 10 on the firmness scale. The coil layer gives the OkiFlex a more responsive feel. Although it contains memory foam, the bed doesn’t “hug” the body as much as other memory foam beds.
A comfort layer, transitional layer, and two support layers make up the OkiFlex Mattress, which measures 11 inches thick. Eleven inches is an average mattress profile, so customers can use standard sheet sets with this bed.
The comfort layer is made of two inches of graphite-infused memory foam. Memory foam softens up this firm mattress, and graphite helps the bed sleep cooler. The memory foam layer also contains air holes to promote temperature neutrality.
Two-and-a-half inches of polyfoam sit below the memory foam and act as a transitional layer. Transition layers provide both comfort and support and help keep sleepers from sinking down to the firm support core. Transition layers also allow heavier parts of the body to sink into the mattress more deeply, while holding up lighter parts of the body to maintain spinal alignment.
The OkiFlex’s support core consists of 5.5 inches of pocketed coils above 1 inch of polyfoam. Pocketed coils are individually encased, so one can be pressed down without automatically contracting the coils around it. For this reason, pocketed coils are better than innerspring layers are when it comes to isolating motion.
Customers only have one option when purchasing the OkiFlex, and that is the 11-inch tall, firm mattress. If customers prefer a softer hybrid mattress, they can turn to the OkiEasy. The OkiEasy features identical construction to the OkiFlex, but its memory foam layer is softer. The OkiEasy rates 6 out of 10 on the firmness scale compared to the OkiFlex’s 7 out of 10.
