Side Sleepers

The GravityLux’s unique construction can relieve pressure and provide support for side sleepers from all weight groups. A quilted cover gives the mattress a plusher feel, while a layer of memory foam shapes to the sleeper’s body to redistribute their weight. The transition layer uses zoned polyfoam that’s softer near the shoulders and legs and firmer near the hips to support a side sleeper’s spinal alignment.

Since the GravityLux comes in three firmness options, side sleepers may be best served by selecting a version that corresponds to their body weight. Side sleepers who weigh under 130 pounds may get better cradling from the Soft version. Those who weigh between 130 and 230 pounds may prefer the contouring and support of the Medium version. Individuals who weigh over 230 pounds may sleep comfortably on the Medium or Firm versions of the GravityLux, though the Medium may be a bit softer than ideal and the Firm may be slightly firmer than they’d prefer.

Sleeping on a mattress that’s softer than ideal could put a strain on a side sleeper’s spine if their hips sink in too deeply. However, sleeping on too firm of a mattress may not allow a side sleeper to sink in enough for pressure relief.

Back Sleepers

Back sleepers usually prefer mattresses with an even surface that supports their natural spinal alignment. The GravityLux Mattress’s zoned transition layer gives extra support around a back sleeper’s hips to reduce sagging. A quilted cover and memory foam comfort layer soften the surface of the bed and contour to the sleeper’s body. This support and cradling may be a good match for back sleepers.

The firmness of the mattress is particularly important for back sleepers. A mattress that is too firm may not allow the sleeper’s hips to sink in much, while a mattress that is too firm may let their hips sink in too deeply.

Back sleepers who weigh under 130 pounds may find the Soft version of the mattress most suitable. Those who weigh over 130 pounds may prefer the additional support of the Firm version of the mattress.

Stomach Sleepers

The GravityLux’s three firmness options can accommodate stomach sleepers from different weight groups. Individuals who weigh under 130 pounds may enjoy good cushioning and even support from the Soft version of the mattress. The Firm version of the mattress may provide better support for stomach sleepers who weigh more than 130 pounds.

Since an individual’s weight is often centered around their bellies and hips, stomach sleepers usually need a mattress with enough support for their midsections. The GravityLux’s zoned transition layer gives extra support near the sleeper’s hips, while the quilted cover and memory foam comfort layer provide cushioning and cradling that many stomach sleepers may enjoy.

Stomach sleepers who weigh under 130 pounds should get the support they need from the Soft version of the GravityLux, and they may prefer its plusher surface. The Firm version of the mattress might strike the right balance of support and cushioning for stomach sleepers who weigh over 130 pounds.

Mattress Performance

Motion Isolation

9.5 / 10

Soft: 10 / 10

Medium: 10 / 10

Firm: 8 / 10

Thanks to its two-layer foam comfort system, the GravityLux absorbs more motion than some all-foam models on the market. The layer of polyfoam and layer of memory foam work together to isolate motion, preventing vibrations from traveling across the surface of the bed. For individuals whose sleep is disrupted when their partner changes, the GravityLux’s strong motion isolation could contribute to a better night’s sleep.

Of the three firmness options, the soft and medium versions absorb more motion due to their softer feel. The firm option also absorbs a lot of motion, but sleepers may experience slight vibrations when their partner moves around more significantly.

Pressure Relief

6.5 / 10

Soft: 8.5 / 10

Medium: 8.5 / 10

Firm: 7 / 10

Pressure relief is one of the GravityLux’s biggest strengths. The gel-infused polyfoam quilted into the cover gives the surface a touch of plushness. A memory foam layer provides deeper contouring, shaping to the sleeper’s body to take pressure off their hips and shoulders. Zoning in the transition layer prevents excessive sinkage around the midsection, balancing the GravityLux’s strong contouring with stable support.

A sleeper’s weight, sleep position, and the mattress firmness they select will determine how much pressure relief they experience. Sleepers who weigh under 130 pounds will likely get the best pressure relief from the soft option since it will allow them to sink in more.

Depending on their preferred sleep position, individuals who weigh between 130 and 230 pounds are likely to prefer the medium or firm versions of the mattress. People who weigh over 230 pounds will probably get the best pressure relief from the firm version. Their extra weight could cause a softer mattress’s foam to overcompress, reducing its pressure-relieving potential.

Temperature Control

6 / 10

Soft: 7 / 10

Medium: 7 / 10

Firm: 8 / 10

Since the GravityLux uses two layers of breathable foam, it sleeps cooler than many all-foam models, so it may be a good choice for people who tend to sleep hot but like the feel of a foam mattress.

The Tencel cover allows airflow into the mattress. This cover is quilted with polyfoam, which is more breathable than most memory foam, allowing heat to dissipate naturally. A gel infusion in the polyfoam also helps pull heat farther away from the sleeper’s body. Cradling from the AirCell memory foam layer provides pressure relief without trapping excessive heat. This material has an open-cell structure so that air can flow more freely through the material, cooling the mattress surface.

While all of the GravityLux’s firmness options sleep cooler than some foam mattresses, the firm version may sleep the coolest since it does not allow sleepers to sink in as deeply.

Edge Support

7 / 10

Soft: 5.5 / 10

Medium: 5.5 / 10

Firm: 6 / 10

As is standard with all-foam models, the GravityLux does not have reinforced edges. Since the foam compresses when weight is applied, people may notice some slight sinkage when they sit or sleep near the perimeter of the bed. The edge is likely to feel sturdier than those of many all-foam models, but this will vary based on the firmness option and the sleeper’s weight.

The soft version of the mattress is likely to have more edge sinkage because of its softer foams, while the firm version of the mattress should have the most stable edge.

The GravityLux’s edge support should allow most people to use the full surface of the bed without avoiding the perimeter, but this may vary between individuals. Sleepers who weigh less will probably feel more secure near the perimeter of the mattress than heavier sleepers.

GravityLux Mattress Review Breakdown

The GravityLux Mattress is available in three firmness options, including soft (4), medium (5), and firm (7). Each firmness option shares the same basic construction and materials.

A Tencel cover encases the mattress. This eucalyptus-derived fabric is breathable, soft to the touch, and designed to pull heat away from the sleeper’s body to reduce body-heat buildup. Quilted into the cover is a 2-inch layer of gel-infused polyfoam, which adds cushioning.

Next, a layer of AirCell memory foam adjusts to the sleeper’s curves to relieve pressure points and support the spine. Microscopic air capsules help absorb motion while permitting more air circulation than standard memory foam.

The Zoned Progression Foam layer uses five distinct zones for targeted support and softness to allow the sleeper’s shoulders and legs to sink in while supporting the hips. This design promotes better spinal alignment.

A polyfoam support core acts as the base of the mattress. This layer uses high-density, 1.8 pounds per cubic foot (PCF) polyfoam, which is engineered to resist sagging and provide lasting reinforcement for the surface of the mattress.

Mattress Sizing

The GravityLux Mattress is higher in price than average for all-foam mattresses, but it’s in-line with other luxury models on the market. Budget shoppers may find it cost-prohibitive, but the mattress’s quality materials and balanced features may make it a good value for some shoppers. Frequent promotions can also bring the price down. Below is a breakdown of height, weight, and size dimensions.
