Meet Our Testing Team
- Sleepers who prefer a balance of contouring and support. Like other all-foam mattresses, the Idle Gel Foam conforms to a noticeable extent, but its medium firm feel prevents excessive sinkage for sleepers who weigh 130 pounds or more.
- Couples. Thanks to its all-foam design, the mattress provides very good motion isolation and does not produce any noise when bearing weight.
- People who normally sleep hot on foam mattresses. The Idle Gel Foam’s ventilated transitional layer promotes extra airflow near the surface of the mattress, allowing sleepers to remain fairly cool despite the polyfoam’s heat-trapping qualities.
- Shoppers looking for a bed with a long sleep trial. At 18 months in length, Idle Sleep’s trial period is among the longest in the mattress industry.
Not Recommended for…
- Sleepers who prefer a very springy mattress. The polyfoam layers offer some responsiveness but the Idle Gel Foam lacks the signature bounce of innersprings and hybrids that many sleepers enjoy.
- Heavier stomach sleepers. While the bed’s balanced medium firm feel is suitable for a wide range of weight groups and sleep positions, stomach sleepers weighing more than 230 pounds are likely to experience excessive sinkage and added pressure.
- People who struggle getting in and out of bed. Due to limited edge support, the mattress tends to sink quite a bit along the perimeter.
Our testing team conducted an extensive evaluation of the Idle Gel Foam. Our review and rating process consists of three parts: in-house evaluation, external sleep testing, and data collection of verified owner experiences. To learn more about our review process, read our methodology here.
Our performance criteria and ratings for the bed are listed in the table below.
As you can see, the Idle Gel Foam has earned mostly favorable ratings from owners and our testing team. For a detailed look at each rating, check out our full breakdown below.
Sleep Position Ratings
As part of our ratings process, we evaluated the Idle Gel Foam across different body types and preferred sleep positions. In addition to physical testing, we surveyed our sleep expert team and analyzed reviews from verified mattress owners and customers. Our findings are listed in the table below.
|Sleep Position||Less than 130 LBS||130 LBS - 230 LBS||Greater than 230 LBS|
How Is the Idle Gel Foam Constructed?
The Idle Gel Foam’s top cover is constructed from a polyester blend with a mid-range weight of 450 grams per square meter (GSM). The mattress also has a bottom cover made from durable base fabric. Both the top and bottom cover can be removed for washing and drying in any household machine.
Inside the mattress, the layers are also encased in a thin cotton sheet that acts as the bed’s fire barrier.
The mattress has a 3-inch comfort layer of Cooling Buoyancy polyfoam. This material is quite adaptive, meaning it will conform to the sleeper’s body and evenly distribute their weight across the surface. Polyfoam is more responsive than memory foam, so there will be a light bounce on the surface when sleepers get in and out of bed – but the mattress is by no means springy.
Beneath the comfort layer rests 2 inches of transitional polyfoam, which prevents sleepers from sinking excessively and coming into contact with the dense base foam. This transitional layer is ventilated with tiny holes to push air currents near the surface of the bed. As a result, the Idle Gel Foam sleeps a bit cooler than many of its all-foam competitors.
The Idle Gel Foam’s support core consists of a solid, high-density polyfoam layer measuring 7 inches thick. The material has a density of 2.4 PCF, making it denser than the base foams found in other mattresses. This layer stabilizes the bed in order to keep sleepers on an even plane and reinforce the perimeter. Despite its dense composition, the foam is still susceptible to sinkage around heavier areas of the sleeper’s body, particularly if they weigh more than 230 pounds.
The Idle Gel Foam measures 12 inches thick and is considered a high-profile model. The above-average height allows room for a thick comfort layer without sacrificing support from the high-density transitional and base foam layers. As a result, the mattress offers a balanced feel with sturdy support and some noticeable body-conforming.
|Product Name||Firmness Level||Support Core Components||Comfort Layer Components||Cover Components|
|Idle Gel Foam||Medium Firm (6)||7″ 2.4 PCF HD Polyfoam||3″ Cooling Buoyancy Polyfoam
2″ Gel-Infused Polyfoam
|Quilted Polyester Blend (450 GSM)|
What Are the Firmness and Feel Like?
The Idle Gel Foam has a medium firm feel. The comfort layer is fairly adaptive and sleepers will notice some body-contouring, but not the close body-hug and deep sinkage they might experience on memory foam. The Idle Gel Foam’s feel could be described as a combination of sleeping “in” and sleeping “on” the mattress.
The polyfoam is also somewhat responsive. When owners change positions or get in and out of bed, they’ll likely feel a light bounce on the surface. Comparatively, memory foam becomes softer when exposed to body heat, so the material responds more slowly to the body.
Next, let’s dig into our performance ratings for the Idle Gel Foam. Each rating listed below is based on reviews and feedback from verified mattress owners, as well as hands-on product analysis from our in-house testing crew.
The Idle Gel Foam is a fairly new model, so we have not had sufficient time to evaluate it against the average mattress lifespan of six to eight years. Our durability rating is based on other factors, such as owner experiences with the mattress, its quality of materials and design, and Idle Sleep’s reputation.
We expect the Idle Gel Foam to perform for about six and a half to seven years before a replacement is needed. Compared to other all-foam mattresses, this estimated lifespan is about average. The medium firm feel and thick support system should prevent excessive sagging and body impressions at first, but over time the foam will soften and lose shape. Sinkage along the perimeter will probably worsen as the Idle Gel Foam nears the end of its lifespan.
Owners can preserve their mattress to some extent by rotating it head-to-foot every three to six months.
To evaluate the Idle Gel Foam for motion isolation, we asked two sleep testers to lie down on the mattress at the same time. One tester moved around on their side while the other felt for this motion transferring across the surface. The mattress demonstrated very good motion isolation during these tests. The foams absorb most movements from sleepers, resulting in minimal transfer.
Although polyfoam tends to be more responsive than memory foam, we did not notice excessive bounciness on the surface of the Idle Gel Foam. This mattress should be suitable for anyone who tends to wake up when their sleep partner changes positions or gets in and out of bed.
Our testers noticed some fairly strong off-gassing odor after unboxing the Idle Gel Foam, but these smells had mostly dissipated when they checked on the mattress a few days later. We don’t foresee any long-term off-gassing issues with this mattress, but owners should know the initial smells can be unpleasant.
Off-gassing is common for all-foam mattresses. The material releases tiny particles known as volatile organic compounds (VOCs) that carry a distinct, plastic-like smell. Owners who notice odor after three or four days should consider moving the mattress into a well-ventilated room, where it can air out its lingering smells.
To evaluate the Idle Gel Foam for pressure relief, our testers took turns lying on the mattress with pressure-mapping sensors around their shoulders, back, hips, and other sensitive areas. They also changed positions to see if pressure increased or decreased when lying on their side, back, or stomach.
Overall, the Idle Gel Foam alleviates pressure quite well. Its adaptive foam layers cushion and contour to side sleepers in order to cradle the spine, promote spinal alignment, and reduce pressure points throughout the body. The medium firm feel also ensures most back and stomach sleepers can rest on an even plane, though some may sink too deeply and feel added pressure around the neck and/or waist.
Most all-foam mattresses are constructed with solid foam layers that can absorb and trap body heat, causing the surface to sleep warm. The Idle Gel Foam is a notable exception thanks to its ventilated transitional layer, which helps air circulate throughout the interior. Sleepers may still notice some heat buildup with this mattress, especially if they weigh more than 230 pounds and sink excessively, but compared to other all-foam beds, this model offers above-average temperature neutrality.
Our testers evaluated the Idle Gel Foam for edge support by sitting along the perimeter as one might do when getting on and off their mattress. They also took turns lying near the edges to test for feelings of “roll-off” that commonly occur with beds that have weaker reinforcement.
Edge support for the Idle Gel Foam is better than average, but our testers still noticed a fair amount of sinkage. This was particularly true for the heavyweight testers. People who weigh less than 130 pounds will have an easier time getting in and out of bed than heavier individuals, and will likely feel more secure sleeping near the edges.
The Idle Gel Foam did not produce any noise during any of our tests, including those that involved position changes and on/off movements. Many all-foam beds share this quality because they lack internal components most commonly associated with mattress noises, such as the coils in innersprings and hybrids, and the air chambers found in airbeds.
Thanks to its low noise potential and great motion isolation, we recommend the Idle Gel Foam to anyone who experiences sleep disturbances due to their partner’s movements in bed.
Most couples prefer springy mattresses for sex that don’t sink excessively and allow them to use the entire surface of the bed. The Idle Gel Foam is not particularly responsive, but sinkage won’t be a major issue for most sleepers due to its medium firm feel and robust support layers. The adaptive foam also provides good traction, which can help couples maintain one position for as long as needed.
The bigger issue for couples will be edge support. While the Idle Gel Foam doesn’t sink as much as many competing all-foam beds, the perimeter may not be strong enough to support two people. As a result, couples may feel confined to the middle of the mattress during sex.
The ideal firmness and thickness for a mattress largely depend on a sleeper’s body weight, shape, and preferred sleep position. In order to better inform our readers and avoid subjectivity in our review, our team evaluated the bed with sleep testers of varying body types and position preferences.
Lightweight Sleepers – Less than 130 lbs.
Our lightweight sleep testers were in agreement that the Idle Gel Foam provided adequate comfort and support, but still felt a bit too firm. Side sleepers weighing less than 130 pounds noted some cushioning for the shoulders and hips, but they still felt some pressure around the lower back. Back and stomach sleepers in this weight group rested comfortably without too much sinkage, but the surface did not conform quite closely enough.
Generally, sleepers who weigh less than 130 pounds prefer mattresses with soft, medium soft, or medium feels. These firmness levels ensure decent body-conforming for their lighter frames. Medium firm and firm mattresses, on the other hand, usually do not contour closely enough to alleviate pressure for these sleepers.
Average Weight Sleepers – 130 to 230 lbs.
Our most favorable ratings for the Idle Gel Foam came from the average weight tester group. This is not surprising given the bed’s medium firm feel, which tends to be popular with sleepers who weigh 130 to 230 pounds. Side sleepers in this weight group sink deeply enough to feel ample padding for the shoulders and hips, but the mattress prevents excessive sagging and added pressure.
The mattress represents the best of both worlds for average weight back sleepers, as well. The sturdy transitional and base foams reinforce the sleep surface to maintain a flat, even surface for their bodies. Stomach sleepers weighing 130 to 230 pounds also felt reasonably comfortable, but they noticed more sagging between the shoulders and waist – a common issue associated with this position.
Heavyweight Sleepers – More than 230 lbs.
Among our heavyweight testers, the best ratings for the Idle Gel Foam came from side sleepers. Those who use this position often require a softer feel to ensure sufficient cushioning and spinal support. Our side sleepers weighing more than 230 pounds felt very little sinkage around the shoulders and hips, and felt less pressure as a result.
Back and stomach sleepers in this weight group noticed less support. Back sleepers felt the most sinkage around their waist, which caused their body to rest at an angle rather than flat on the surface. Heavyweight stomach sleepers gave the mattress a fair rating, citing excessive sinkage around the chest, midsection, and hips and some added neck and shoulder pain.

How Does the Idle Gel Foam Compare to Other Beds?
When searching for a new mattress, we always encourage shoppers to compare as many brands and models as possible. This ensures they’ll be able to find a mattress that meets their sleep needs, comfort preferences, and budget. In the next section, we’ll see how the Idle Gel Foam stacks up to other Idle Sleep models and some similar mattresses from competing online brands.
Idle Gel Foam vs. Idle Gel Plush
Essentially a softer version of the Idle Gel Foam, the Idle Gel Plush measures 14 inches thick and has a medium (5) feel with ample cushioning. The mattress contains the same components as the Idle Gel Foam, plus a memory foam transitional layer that promotes close body-contouring.
Aside from construction and feel differences, these mattresses are quite similar. Both provide very good motion isolation and do not produce any noise, making them ideal for couples. They also alleviate pressure quite well; the Idle Gel Plush is better suited to lightweight sleepers due to its softer feel, while the Idle Gel Foam caters to heavier sleepers with less conforming and more support. The Idle Gel Foam does sleep a bit cooler than the Idle Gel Plush due to its ventilated transitional layer, but both beds lack strong edge support.
Since the Idle Gel Plush contains an additional layer, its price-point is slightly higher than the Idle Gel Foam’s. That said, both beds are somewhat expensive compared to the average all-foam model. If budget is not a major concern, buyers should base their decision on how much cushioning and contouring they want from their mattress.
Idle Gel Foam vs. Idle Hybrid
The flagship Idle Hybrid is a flippable mattress, meaning the top and bottom sides are equipped to serve as sleep surfaces. Customers can choose a medium firm (6) or firm (8) feel for both sides, or opt for a different feel on each. Both sides feature three foam layers to cushion the body, while the shared support core contains 6-inch pocketed coils.
The Idle Hybrid has some advantages over the Idle Gel Foam. For one, its coil system provides strong reinforcement to reinforce the edges and prevent heavier sleepers from sinking too deeply. The coils also promote steady airflow to help the mattress maintain a comfortable core temperature. The Idle Gel Foam sleeps cooler than average thanks to its ventilated transitional layer, but the hybrid has the edge in this category. However, the Idle Gel Foam outperforms for motion isolation and pressure relief.
The Idle Hybrid costs quite a bit more than the Idle Gel Foam, but its sticker price is actually below-average for a hybrid. Sleepers who want a mattress that contours to the body and reduces pressure points may want to consider the Idle Gel Foam, while those who would rather sleep on a responsive coil mattress should choose the Idle Hybrid instead.
Idle Gel Foam vs. Idle Latex
Another reversible model from Idle Sleep, the Idle Latex features latex comfort layers on its top and bottom sides. As with the Idle Hybrid, customers can select a medium firm (6) or firm (8) feel for both sides, or choose one of each for more versatility. Idle Sleep also offers two types of latex: Dunlop, which is dense and heavy; or Talalay, which is light and bouncy.
The Idle Latex and Idle Gel Foam have very different feels. Latex conforms to a minimal extent and feels highly responsive, so sleepers on the Idle Latex experience more bounciness when they get on the mattress and less sinkage as their bodies settle. The latex layers in this mattress are also highly durable while the coils provide long-lasting support, so its expected lifespan is at least one year longer than the Idle Gel Foam’s. Strong edge support is another advantage. The Idle Gel Foam outperforms in other areas, such as motion isolation and pressure relief for lighter people and side sleepers.
Construction and performance differences aside, the Idle Latex costs – at minimum – about three times as much as the Idle Gel Foam. Understandably, most buyers will base their decision on price-points.
Idle Gel Foam vs. Bear Mattress
The Bear Mattress is an all-polyfoam model. It is constructed with an adaptive, open-cell comfort layer over transitional and support layers of high-density foam, creating a firm firm feel for the mattress that is very comparable to the Idle Gel Foam’s.
Both of these mattresses also sleep cooler than many competing all-foam models. The Idle Gel Foam accomplishes this thanks to a ventilated transitional layer that pushes airflow toward the surface. Likewise, the open-cell comfort layer of the Bear Mattress is fairly breathable and won’t trap too much body heat for most sleepers weighing up to 230 pounds. Other similarities these two models share include very good motion isolation, consistent pressure relief for side and back sleepers, and limited edge support.
Prices for the Idle Gel Foam and Bear Mattress are very comparable, as well. One benefit of selecting the Idle Gel Foam is that customers qualify for Idle Sleep’s 18-month sleep trial, one of the longest in the mattress industry. Bear’s sleep trial spans for 100 nights.
Idle Gel Foam vs. Brooklyn Bedding Signature
The Brooklyn Bedding Signature is a hybrid model available in a soft (3.5), medium (5.5), or firm (7.5) feel. The comfort layer is made of an adaptive polyfoam material similar to the Idle Gel Foam’s, but the Signature’s pocketed coil support core provides more responsiveness and support for this mattress.
Temperature neutrality is better for the Signature thanks to a coil layer that generates steady airflow to keep the mattress cool. The Idle Gel Foam’s ventilated transitional layer promotes some cooling, but not as much. The Signature’s firmness selection is another asset, since it covers a wide range of sleeper preferences and will be suitable for most weight and position groups. However, those seeking a medium firm feel may still find the Idle Gel Foam more comfortable. This mattress may also be suitable for noise-sensitive sleepers, as the Signature’s coils may squeak occasionally.
Compared to the Idle Gel Foam, customers pay more for the Signature and qualify for a shorter sleep trial. However, anyone who feels more comfortable on a hybrid or seeks a mattress with a feel that is softer or firmer than a medium firm should consider the Signature.
Idle Gel Foam vs. Tuft & Needle
The T&N Original from Tuft & Needle is quite similar to the Idle Gel Foam. This all-polyfoam mattress is constructed with a 3-inch comfort layer of graphite-infused foam over a high-density base. Both beds are adaptive yet supportive, and offer comparable medium firm feels. Their comfort layers are lightly responsive, as well.
The T&N Original and Idle Gel Foam have earned similar ratings in other performance categories, as well. Both beds alleviate pressure quite well for side and back sleepers, and also eliminate most motion transfer for couples. These mattresses also sleep cooler than average. The T&N Original’s comfort layer is composed of open-cell foam that traps a minimal amount of body heat. In terms of edge support, the Idle Gel Foam is slightly stronger but both beds tend to sink a bit.
The T&N Original has a lower price-point, but the Idle Gel Foam’s sleep trial is much longer. Since these two mattresses are comparable in most other ways, many customers will base their decision on these factors instead.
