Gravity launched with a successful Kickstarter campaign for the Gravity Blanket, a weighted blanket designed to help reduce stress and anxiety. Since then, the company has expanded and developed its product line to include a cooling blanket, sheets, bedding, sleep accessories, and the Gravity Ice Hybrid Mattress.

The Gravity Ice Hybrid, which we cover in this review, is designed to be compatible with the Gravity Blanket, but is also supportive and comfortable on its own. The mattress has a hybrid construction with multiple foam layers for deep contouring and coils for sturdy support. High-density polyfoam adds durability to the mattress, while a cooling gel layer and coil base help dissipate heat and regulate temperature.

There are plenty of benefits to sleeping on a foam hybrid mattress, as sleepers can experience the pressure relief and motion isolation of memory foam and the full-body support of innerspring coils. We’ll break down the construction of the Gravity Ice Hybrid so shoppers know what to expect from each layer.

We’ll outline comprehensive performance ratings for the Gravity Ice Hybrid, in addition to pricing and sizing details. We’ll also discuss who the Gravity Ice Hybrid may be best-suited for, in addition to company policies that shoppers should be familiar with when deciding on a mattress.

Mattress Performance

Motion Isolation

A mattress that absorbs movements, such as changing sleeping positions or getting in and out of bed, can minimize sleep disturbances by ensuring these movements are not felt across the bed. This is essential for sensitive sleepers who share the bed with a partner.

Memory foam typically offers standout motion isolation, and the Gravity Ice Hybrid has 3 inches of memory foam in its comfort system. The comfort layers respond to pressure and return to shape slowly, helping to isolate movements.

While coils add bounce to a mattress, the coils used in the Gravity mattress are pocketed so that they respond independently to pressure. Additionally, the coils are encased by layers of polyfoam that help reduce motion transfer. As a result, the Gravity Ice Hybrid isolates motion a bit better than the average hybrid mattress.

Pressure Relief

The Gravity Ice Hybrid responds to pressure and evenly contours to the shape of the body. The thick memory foam comfort system and medium firmness of the mattress results in substantial pressure relief.

The mattress evenly distributes body weight and cushions areas like the hips and shoulders, where pressure is most likely to build. The transition layer and coils give the mattress some push back to ensure sleepers still feel supported.

Pressure relief is important for everyone, but side sleepers and those with chronic joint pain or other orthopedic concerns can often especially benefit from a conforming mattress. The Gravity Ice Hybrid has a body-hugging feel that is ideal for these sleepers.

Temperature Control

Hybrid mattresses tend to regulate temperature well, but memory foam can retain body heat. The Gravity Ice Hybrid offsets any potential heat retention with a cooling top panel and gel-infused memory foam. These layers wick heat away to keep sleepers feeling cooler than they would on a traditional memory foam mattress.

The coils add airflow throughout the mattress, helping to further dissipate any residual heat. This is beneficial for hot sleepers and anyone living in warm or humid climates.

It is important to note that bedding also plays a role in temperature control. Breathable, lightweight materials can help keep sleepers comfortable and ensure that they experience the cooling benefits of the Gravity Ice Hybrid.

Edge Support

The comfort layers of the Gravity Ice Hybrid compress easily, but the edges are boosted by the high-density foam transition layer and the foam encasement around the coils. This helps the edges feel sturdy and supportive, so sleepers can comfortably use the entire mattress.

The Gravity Ice Hybrid has better edge support than an all-foam mattress would likely provide, but some hybrid mattresses use thick steel coils for sturdier edge support.

Edge support prevents sagging along the perimeter over time, helping those who frequently sit on or sleep near the edge of the bed feel supported. It also makes it easier to get in and out of bed.

Ease of Movement

Ease of movement indicates how well the mattress facilitates changing positions or moving around. The medium firmness and thick memory foam comfort system of the Gravity Ice Hybrid offer close contouring for pressure relief, but this can inhibit movement to a certain extent. Memory foam is not as resilient as latex, so it does not spring back to shape as quickly. Users will sink into the first two layers of the mattress and may feel somewhat restricted.

That said, the high-density polyfoam transition layer prevents sinking in too much, and the coils add bounce to the mattress. This makes it easier to change positions and move around on the surface of the bed.

Ease of movement is especially beneficial for combination sleepers who shift positions throughout the night. Most sleepers will find they can comfortably move around on the Gravity Ice Hybrid, though it may not be as bouncy as other hybrid models.


The memory foam comfort layers of the Gravity mattress provide traction, but the lower resilience of memory foam means it returns to shape more slowly and can feel restrictive during amorous activity.

However, the coils add bounce to the mattress and most couples will find the Gravity Ice Hybrid is sufficient for sex. The mattress offers good edge support with a high-density foam encasement, and couples can use the entire surface area of the bed. Since the coils are encased by a foam perimeter, there is minimal noise.

Some couples may prefer a hybrid mattress with a more resilient comfort system, like latex, for better ease of movement.


Shoppers can expect a new mattress smell when the Gravity Ice Hybrid is first unboxed. This odor is common with mattresses that have foam layers, as volatile organic compounds (VOCs) are released as the mattress airs out.

Since the Gravity mattress has a hybrid construction, there is less off-gassing than is typical of all-foam models. Still, the mattress is likely to off-gas for a couple of days.

Ventilating the bedroom can help expedite this process, and Gravity recommends leaving the mattress uncovered for the first few days for better air circulation. The coil base also helps air flow throughout the mattress to dissipate odors.

The Gravity Ice Hybrid is a good fit for most sleeping positions and body types, as the memory foam layers provide even contouring while the coils ensure proper support. That said, body weight and personal preferences can affect how comfortable and supportive a mattress feels. We’ll break down important considerations for shoppers based on sleeping position and body weight here.

Side Sleepers

Side sleepers benefit from a responsive mattress that offers contouring for their shoulders and hips. This prevents pressure from building up in these key areas, while helping to keep the spine aligned. The Gravity Ice Hybrid evenly distributes body weight and cushions pressure points for side sleepers.

The medium (5) firmness is ideal for side sleepers, especially if they weigh less than 230 pounds. The mattress hugs the body for a feeling of sleeping in, rather than on, the mattress. High-density transition foam keeps side sleepers from sinking in deeply and the coil base offers ample support.

Side sleepers who weigh more than 230 pounds should still feel supported, though some may prefer a firmer surface.

Back Sleepers

Back sleepers typically maintain a neutral posture as they sleep, but pressure can build in the lumbar region. As a result, these sleepers benefit from a contouring mattress like the Gravity Ice Hybrid, as it cushions the lower back and helps relieve pressure.

The supportive coils and high-density foam helps keep sleepers from pressing deeply into the mattress and promote proper spinal alignment. The medium firmness and body-hugging memory foam are best for back sleepers who weigh less than 130 pounds, but the mattress provides adequate support for those who weigh more.

Stomach Sleepers

Stomach sleepers need proper support for their lower backs and tend to prefer a firm mattress. If their abdomens and hips sink in too deeply, pressure builds in the lumbar region and causes discomfort. That said, the mattress should provide some contouring for the upper body to keep the chest and shoulders comfortable.

The Gravity mattress balances thick, conforming comfort layers with high-density transition foam and supportive coils. The supportive layers resist sagging over time, providing an even surface for stomach sleepers. Though sleepers may press into the mattress, the thick comfort system should evenly distribute body weight to help keep the spine aligned.

The Gravity Ice Hybrid is a good fit for stomach sleepers under 130 pounds and supportive enough for heavier stomach sleepers, though most will likely prefer a medium firm (6) to firm (8) mattress instead.

Gravity Ice Hybrid Mattress Review Breakdown

The Gravity Ice Hybrid has layers of memory foam and high-density polyfoam, with a pocketed coil support core. The 12-inch profile is standard for a mattress and deep pocket fitted sheets are not required. Purchasers can use the Gravity Blanket with the Gravity Ice Hybrid for a combination of deep touch pressure from the blanket and full-body support from the hybrid mattress.

Overall, the mattress has a medium firmness, rated as a 5 on the 10-point firmness scale. Sleepers can expect the body-hugging feel of memory foam, but with added bounce and support from the coils below.

The cover of the Gravity Ice Hybrid includes a cooling top panel that helps wick heat away to keep sleepers comfortable. Black mesh side panels encourage airflow throughout the mattress. The bottom of the mattress cover is composed of polyester.

Beneath the cooling top panel is a 1-inch layer of gel memory foam that helps regulate temperature and offsets memory foam’s tendency to retain heat. A second 2-inch layer of memory foam relieves pressure points and conforms closely to the shape of the body, cushioning areas like the shoulders, hips, and lumbar region. Having a thick memory foam comfort system ensures close contouring and top-notch pressure relief. It also helps isolate motion and minimize sleep disturbances for those who share the bed.

A transitional layer of high-density polyfoam provides additional support and keeps sleepers from pressing into the support core. A 6-inch base of pocketed coils circulates air throughout the mattress while providing even support. This foundation increases the durability of the mattress and prevents sagging over time. A high-density polyfoam encasement bolsters the amount of edge support the mattress provides. The Gravity Ice Hybrid has a 2-inch bottom layer of high-density polyfoam to reinforce the coil base and reduce motion transfer.
