Gravity Ice Hybrid Mattress Review

Gravity is a bedding company best known for the Gravity Blanket, a weighted blanket that's designed to improve sleep by reducing stress. Since gaining recognition from a successful Kickstarter campaign in 2017, Gravity has gone on to develop a range of bedding, home, and wellness products. One of the more recent releases is the Gravity Ice Hybrid mattress.

The Gravity Ice Hybrid represents Gravity's first foray into the mattress scene. Utilizing a hybrid design with memory foam over pocketed coils, the mattress aims to capitalize on the benefits of each. It has a medium firmness level, or 5 out of 10, with a neutral feel that many sleepers should find comfortable.

This Gravity Ice Hybrid review covers details on materials and construction, as well as a summary of sleep trial, shipping, and warranty policies. We'll also take a look at how the mattress performs for different types of sleepers to help you decide if the mattress is right for you.

Gravity Ice Hybrid Mattress Review: Our Verdict

The Gravity Ice Hybrid mattress succeeds in uniting the advantages of an all-foam and an innerspring mattress. The mattress offers solid pressure relief and motion isolation, yet it also manages to incorporate satisfactory edge support, temperature neutrality, and ease of movement.

With its carefully constructed blend of support and pressure relief, the Gravity Ice Hybrid welcomes sleepers of all body types and preferred sleeping positions. That said, it performs exceptionally well for side sleepers under 230 pounds and back sleepers under 130 pounds.

In terms of sleep trial and warranty policies, the Gravity Ice Hybrid is right on par with the industry standard. Though reasonably priced for a hybrid mattress, the mattress may be out of range for shoppers on a budget.

Choose the Gravity Ice Hybrid if...
  • You're a side sleeper under 230 pounds, or a back sleeper under 130 pounds
  • You like a balanced, well-rounded feel
  • You sleep with a partner
  • You tend to wake easily from noise or movement
Keep Shopping if...
  • You prefer an extremely plush or extremely firm mattress
  • You need a twin, twin XL, or California king size
  • You're looking for White Glove delivery or old mattress removal

How Much Is the Gravity Mattress?

The Gravity Mattress is one of the more affordable hybrid mattresses on the market. The mattress is made with good-quality foams and a hybrid construction that should promise a fairly long lifespan. Gravity also offers occasional discounts that further lower the price.

The Gravity Ice Hybrid is currently only available in full, queen, and king sizes, which may be a dealbreaker for shoppers needing to outfit a twin, twin XL, or California king size bed.

How Does the Gravity Mattress Feel?

The Gravity Ice Hybrid mattress has a medium feel that provides a balance of support and pressure relief. On a firmness scale of 1 to 10 with 10 being the firmest, this mattress would rank a 5.

The comfort section mostly consists of memory foam that wraps around the sleeper, helping reduce pressure in common problems areas such as the hips and shoulders. The memory foam has a fairly slow response to pressure, and most sleepers have the impression they are sleeping "in" rather than "on" the mattress.

This effect is counteracted by the firmer transitional layer and pocketed coils, which help maintain spinal alignment and prevent sleepers from sinking in too deep. The coils also add responsiveness so sleepers don't feel stuck in the bed.

Overall, the mattress succeeds at providing pressure relief on a level comparable to an all-foam mattress, while still including the extra support that comes from an innerspring base. This makes the mattress suitable for a wide range of sleeper types.

What Is the Gravity Ice Hybrid Made Of?

The Gravity Ice Hybrid mattress has 5 layers in total, consisting of 3 foam comfort layers, a pocketed coil support core, and a high-density polyfoam base. The mattress stands at 12 inches tall. While slightly higher than some mattresses, this is an average height for a hybrid mattress, allowing room for a full comfort section over the pocketed coils.

  • Cover Material: The Gravity Ice Hybrid has a cover made of ice cooling fabric and mesh side panels to allow for better breathability. These features are designed to help keep the surface of the mattress cool and dry. The bottom mattress cover is made of polyester.
  • Comfort Layers: An inch of medium-density gel memory foam lies just below the mattress cover. This provides an initial plush, cushy feel, and the gel helps combat the heat retention that sometimes occurs with memory foam. Beneath this top layer is a 2-inch layer of memory foam for deep conforming and pressure relief. Finally, a 1-inch layer of firmer polyfoam helps ease the transition onto the support core.
  • Support Core: The mattress has a 6-inch support core constructed with pocketed coils, which provide robust support for heavier frames. The coils have a high-density polyfoam encasement running along the perimeter of the bed to ensure edge-to-edge support. There is also a 2-inch layer of polyfoam underneath the mattress that acts as a stable base for the mattress.

Does it Isolate Motion?

Rating: 4/5

The Gravity Ice Hybrid mattress performs very well on motion isolation. This is largely thanks to the memory foam comfort layer section, which conforms closely to the sleeper without transferring movement to the surrounding areas. People who share the bed should find they are able to freely shift positions without causing too much disturbance to their sleeping partner.

Hybrid mattresses made with pocketed coils tend to transfer less motion than those with interconnected coils, because the coils move independently of each other. Moreover, where most hybrid mattresses have a 1-inch foam base, the Gravity Ice Hybrid has 2 inches of foam below the coils. This adds a little extra absorption to blunt motion transfer in the support core.

Does it Sleep Cool?

Rating: 4/5

Most sleepers should find that the Gravity Ice Hybrid stays at a relatively neutral temperature through the night. The breathable cover and pocketed coils help boost airflow to reduce heat build-up.

Still, hot sleepers may find the Gravity Ice Hybrid to be a little warmer than other hybrid mattresses due to the multiple layers of memory foam. Memory foam is known for trapping heat, and the mattress's plusher feel means that sleepers sink into the mattress and leave less room for heat to escape. The Gravity Ice Hybrid has incorporated gel infusions in the memory foam to stave off this effect, but a latex hybrid may be a better choice for those who need standout cooling.

Will It Sag Along the Edges?

Rating: 3/5

The Gravity Ice Hybrid offers decent edge support. While not as sturdy as hybrid models that use thicker coils around the perimeter, the pocketed coils and high-density polyfoam encasement in the Gravity Ice Hybrid ensure minimal compression around the perimeter of the mattress.

Individuals who weigh more than 230 pounds may experience some sinkage when sitting on or lying near the edge of the bed, but most sleepers should be able to sleep right up to the edge of the mattress. Those who rely on the edges when getting in and out of bed may prefer a mattress with extra edge support.

Is It Good for Sex?

Rating: 3/5

The Gravity Ice Hybrid has a fairly responsive surface that meets the requirements of most couples for sex. The pocketed coils and memory foam complement each other, providing sufficient traction as well as some pushback to help enable movement on top of the bed. Reliable edge support allows for unimpeded positioning, and the individually wrapped coils keep noise to a minimum compared with a traditional innerspring mattress.

Some couples may find that the slow-responding memory foam of the Gravity Ice Hybrid makes it difficult to switch positions. Those who like a highly bouncy surface for sex may prefer a firmer foam hybrid or a latex mattress.

What About Off-gassing?

Rating: 3/5

A faint off-gassing smell may be noticeable when the Gravity Ice Hybrid mattress is first unboxed. This is the result of volatile organic compounds (VOCs) coming into contact with the air, and it is a common process with mattresses that contain synthetic foams.

A by-product of the foam manufacturing process, the smell is generally considered harmless and it frequently disappears within a few days. The Gravity Ice Hybrid allows ample room for airflow through the coils, which should help the odor dissipate quicker.

What Type of Sleeper Is the Gravity Ice Hybrid Best For?

With its medium firmness level and balanced feel, the Gravity Ice Hybrid can be used for any sleeping position, although it's ideally suited to side and back sleepers under 130 pounds.

  • Side Sleepers: The Gravity Ice Hybrid mattress is an excellent choice for side sleepers, particularly those who weigh less than 230 pounds. Soft foams cushion the hips and shoulders, allowing the sleeper to sink in just the right amount for optimal spinal alignment. The mattress is also suitable for side sleepers over 230 pounds, although these sleepers may experience some slight pressure build-up where heavier body parts come into contact with the support layers.
  • Combination Sleepers: The Gravity Ice Hybrid accommodates virtually every sleeping position. Despite the slow-responding memory foam, the mattress's hybrid construction allows sleepers to switch positions without too much effort. Stomach sleepers may find the mattress a tad on the soft side, but most combination sleepers should be comfortable in all sleeping positions.
  • Back Sleepers: For back sleepers under 130 pounds, the Gravity Ice Hybrid does a stellar job of providing lumbar support. The memory foam fills in the gap below the lower back, while the coils provide targeted support to encourage healthy spinal alignment. This construction also performs well for back sleepers who weigh more than 130 pounds, though some may prefer a firmer surface to prevent sagging under the hips.
  • Stomach Sleepers: Some stomach sleepers will find the Gravity Ice Hybrid a bit too soft. This is especially true for those over 230 pounds, but may be an issue for any stomach sleeper over 130 pounds.

How Does Body Weight Impact Performance?

The Gravity Ice Hybrid may feel different from one sleeper to the next, depending on body weight. While the mattress firmness is best described as medium, those who weigh less may find it firmer, and those who weigh more may find it softer.

Sleepers under 130 pounds receive excellent cushioning from the Gravity Ice Hybrid. The comfort layers cradle the body when sleeping on the side, and the pocketed coils provide targeted lumbar support for back sleepers.

Side sleepers who weigh between 130 and 230 pounds also rate the mattress highly. For these sleepers, the mattress provides sufficient pressure relief and helps with spinal alignment. Stomach and back sleepers may find some sinkage occurs under the hips, but this should be minimal.

Sleepers over 230 pounds usually require a firmer surface, but the Gravity Ice Hybrid performs better than expected for these individuals. The pocketed coils step in to help distribute body weight and ensure that the hips don't sink in too far. Side, back, and stomach sleepers in this category all receive sufficient support and pressure relief from the mattress.

Is it Good for Couples?

The Gravity Ice Hybrid offers a nice compromise for couples with different body types or preferred sleeping positions. It's quiet and it provides superior motion isolation, making this mattress a good choice for those who share the bed with a sensitive sleeper.

For couples using a smaller size mattress, the Gravity Ice Hybrid offers relatively stable edges. This should give each person the confidence to spread out and take full advantage of their side of the bed. The exception may be couples in which one or both sleepers weigh more than 230 pounds. In this case, the mattress may be somewhat unstable when sleeping near the edge of the bed.

Due to its hybrid construction, the Gravity Ice Hybrid has a responsive feel that enables easy movement. Most couples can also snuggle together without overheating on the Gravity Ice Hybrid. That said, for couples who live in hot climates, it might be a safer bet to invest in a latex or latex hybrid mattress.
