Polysleep, a Canadian company with an environmentally and socially conscious mission, makes regular donations to charitable organizations. It also has shipping policies in place to reduce its carbon footprint. The Polysleep product line includes a pillow, bed foundation, and three mattress models: the Polysleep, the Origin, and the Zephyr. The company uses a proprietary foam blend in its mattresses. The flagship Polysleep, which we cover in this review, is the brand’s mid-level price point model.

The Polysleep mattress includes the company’s Hybrid viscoelastic polyfoam , which is a proprietary memory foam formulation, in its comfort system to relieve pressure points. It conforms to the shape of the body to cushion the shoulders and hips. The mattress features a reinforced perimeter, which is unique for a foam mattress. This results in better edge support for sleepers. With a machine washable, liquid-repellent cover, the Polysleep mattress is easy to keep clean.

For a better understanding of the Polysleep, we’ll cover its construction, sizing, and pricing. Based on sleeping style and body weight, we’ll also break down who will benefit most from the Polysleep mattress. Lastly, we’ll review verified customer feedback and pertinent company policies.

Polysleep Mattress Review Breakdown

The Polysleep is a foam mattress with a height of 10 inches. The mattress has three foam layers, including the company’s viscoelastic Hybrid memory foam and high-density polyfoam. The foams used are CertiPUR-US certified. This means they are made without harmful chemicals or heavy metals.

The Polysleep is available in a medium firm feel, which is considered to be a 6 out of 10 on the firmness scale. The memory foam comfort layer conforms closely, hugging the body for ample pressure point relief. This cradling effect reduces tension and cushions the joints. This is ideal for side sleepers. Most sleepers will find they sink into the comfort layer of the mattress, but the high-density transition layer prevents them from sinking in too deeply.

The cover of the Polysleep mattress is composed of polyviscose, polyester, and spandex. It includes a liquid repellent treatment to minimize any spills or stains. Additionally, the cover can be removed and machine washed. The breathable mesh sides of the cover increase airflow throughout the mattress and help dissipate heat.

The comfort layer is antimicrobial memory foam polyfoam. This layer contours closely, but returns to its original shape quickly when pressure is removed. This helps sleepers change positions without feeling too restricted. The polyfoam comfort layer is aerated for temperature regulation. It also has an open-cell structure that helps dissipate heat. The antimicrobial foam resists dust and bacteria.

Beneath the comfort layer is transition polyfoam. This high-density foam layer provides support and helps keep the spine aligned.

The support core of the Polysleep mattress is made of firm, high-density polyfoam. This base provides even and consistent support for sleepers. There is an edge reinforcement polyfoam system that encases the transition and support layers of the mattress. This high-density perimeter provides better edge support than the average foam mattress. It ensures those who sleep or sit near the edge of the bed feel supported. It also helps prevent sagging along the edges over time.

Mattress Performance

Motion Isolation

There is minimal motion transfer on the Polysleep. The foam layers help isolate motion and minimize sleep disturbances. Generally, foam mattresses isolate motion well and are preferred by those who share the bed with a partner and are easily awakened by their partner’s movements.

The all-foam construction of the Polysleep has minimal bounce. The memory foam comfort layer layer conforms closely to the body. The cradling effect helps minimize motion transfer.

Co-sleepers are unlikely to feel their partner shift positions throughout the night. Larger, more substantial movements like getting in and out of bed may be felt to a certain extent.

Pressure Relief

Foam mattresses typically relieve pressure better than other mattress types. The Polysleep is on par with most foam mattresses. It has a mid-range firmness that lets sleepers sink in to a certain extent. The cradling effect of the comfort layer delivers top-notch pressure relief. It conforms to the shape of the body and cushions areas where pressure would likely develop. The transition layer prevents sinking in deeply, which helps keep the spine aligned.

Side sleepers who weigh less than 230 pounds especially benefit from the pressure-relieving qualities of the Polysleep. The foam construction cushions the shoulders and hips while supporting the body. This balance of support and comfort is also ideal for back sleepers who weigh less than 130 pounds.

Those who weigh more than 230 pounds or tend to sleep on their stomachs may find they sink into the mattress too much. This can put pressure on the spine.

Temperature Control

Foam mattresses have a reputation for sleeping hot, as memory foam responds to heat and pressure to conform closely. The Polysleep regulates temperature better than the average foam bed. The construction of the mattress helps dissipate heat and adds airflow throughout the mattress.

The cover of the Polysleep has mesh side panels, which lets air circulate throughout. The comfort layer is ventilated, and the open-cell structure of the foam retains less heat than traditional memory foam. This prevents heat buildup around the body. Overall, the Polysleep has a temperature neutral feel for most.

That said, the mattress conforms closely and has high-density polyfoam layers. This can result in heat retention for some.

Edge Support

A common issue with foam mattresses is that they lack a reinforced perimeter and have minimal edge support as a result. The Polysleep is unique in that it uses high-density polyfoam as a support system around the perimeter of the mattress. This gives the Polysleep sturdy edge support, especially compared to other foam models.

Edge support increases the usable surface area of the mattress, which is important for those who share the bed. It ensures those who sleep near the edge of the bed are as supported as they would be in the center. It also makes it easier to get in and out of bed.

The comfort layer of the Polysleep mattress compresses easily, but returns to its original shape quickly. The reinforced perimeter prevents sinking in too deeply. The support foam also reduces the likelihood of sagging along the edges.

Ease Movement

The proprietary Hybrid memory foam comfort layer of the Polysleep provides better ease of movement than traditional memory foam. It returns to its original shape quickly when pressure is removed, which prevents the feeling of being trapped in the comfort layer. As a result, the Polysleep is not as restrictive as other foam mattresses.

Though the mattress conforms closely, the transition layer helps facilitate movement and keeps sleepers from sinking in deeply. The firm foam base adds support to the mattress.

Combination sleepers should be able to change positions easily. That said, the Polysleep has minimal bounce. It does not facilitate movement as well as a hybrid mattress with innerspring coils might.


The Polysleep is rated similarly to other foam mattresses for amorous activity. Foam mattresses are not as bouncy as hybrid and latex models, which means they are less likely to facilitate movement. This can make it difficult to change positions. The Polysleep may not be sufficient for some couples.

That said, the Polysleep offers better edge support than most foam mattresses. This allows couples to use the entire surface area of the mattress comfortably.

The medium firm feel of the mattress and foam comfort layer provide traction for changing positions. Additionally, the mattress is discreet, as it does not make any noise when bearing weight.


The Polysleep mattress off-gasses, but any initial odor should dissipate within a couple of days.

Off-gassing is the result of volatile organic compounds being released into the air. It is generally not considered harmful. The Polysleep is CertiPUR-US certified, so it is low in VOCs and is made without ozone-depleting chemicals.

The breathable mesh panels of the cover and the ventilated comfort layer help the Polysleep mattress air out. Make sure the bedroom is well-ventilated to expedite the process.

Sleeping Style and Body Weight

Side Sleepers: Side sleepers benefit from the pressure relief that the Polysleep provides. The shoulders and hips of side sleepers need ample cushioning to prevent pressure points. That said, side sleepers also need full-body support to keep the spine aligned. The Polysleep balances this cushioning comfort and support for side sleepers who weigh less than 230 pounds.

Those who weigh less than 130 pounds find that the Polysleep is soft enough for them to experience full-body contouring. The comfort layer cradles the body and keeps pressure from building at the shoulders and hips.

Side sleepers who weigh between 130 and 230 pounds also rate the Polysleep highly. The mattress conforms closely for pressure relief. The transition layer keeps these sleepers from sinking into the support base and helps keep the spine aligned.

Side sleepers who weigh more than 230 pounds will likely find the Polysleep is too soft. These sleepers often need a firm mattress for better support. The lower profile and plush foam comfort layer of the Polysleep allow these sleepers to sink in too deeply. As a result, the mattress is less supportive.

Back Sleepers: Even support helps keep the spine aligned for back sleepers. This sleeping position promotes a neutral posture. Cushioning foam, like that of the Polysleep mattress, helps support the lumbar region. The Polysleep mattress is a good choice for back sleepers who weigh less than 130 pounds. It cradles the body and contours closely for pressure relief. The transition layer helps keep the spine aligned.

Those who weigh between 130 and 230 pounds and sleep on their backs find the Polysleep offers alright support. These sleepers often prefer a firmer mattress, and the Polysleep is considered medium firmer (6). As a result, back sleepers in this weight category are more likely to sink deeply into the mattress. This may cause back sleepers to feel less supported, and can lead to spinal misalignment if sleepers sink in too much.

Back sleepers who weigh more than 230 pounds could also sink in excessively. The 10-inch profile of the mattress is less ideal for sleepers who weigh more than 230 pounds, as they are more likely to feel the firm support core beneath the comfort and transition layers. They are less likely to benefit from the contouring comfort layer, and pressure could build in the lower back. A firm mattress may be more beneficial.

Stomach Sleepers: The Polysleep is a good fit for stomach sleepers who weigh less than 130 pounds. Generally, stomach sleepers need a firm mattress that supports their midsections. This keeps pressure off of the lower back by keeping the spine aligned. Those who weigh less than 130 pounds are not as likely to sink into the Polysleep when sleeping on their stomachs. The foam layers properly support their abdomens and hips while cushioning their chests and shoulders.

Stomach sleepers who weigh between 130 and 230 rate the Polysleep as fair. These sleepers are more likely to feel their lower body sinking into the mattress, but the comfort layer cushions the upper half of the body.

Those who weigh more than 230 pounds and sleep on their stomachs will find the Polysleep is too soft to sufficiently support them. Additional weight is often carried in the midsection, and a firm mattress keeps the hips and abdomen from sinking in. The medium firm feel of the Polysleep is less ideal for stomach sleepers in this weight category, as they typically prefer a firm (7 or 8) surface.
