How Much Is the GravityLux Mattress?

As a premium model, the GravityLux Mattress carries a higher ticket price than average for all-foam models. This extra expense may be justified by the bed’s proprietary materials and quality construction. WinkBeds produces the GravityLux in the six standard mattress sizes, and your firmness selection does not affect the price.

How Does the GravityLux Mattress Feel?

Three of the GravityLux’s four foam layers use proprietary foams, including AirCell Memory Foam, Zoned Progression Foam, and ATLAS Core Foam. These unique materials greatly affect the feel of the bed, which we’ll detail more below. In general, sleepers can expect cradling without the same close hug often associated with traditional memory foam. The GravityLux is also more responsive and breathable than some all-foam models.

Since the bed comes in three firmness options, the exact feel will vary based on the firmness you select and your weight. The Soft option will feel plusher to most individuals, making it especially appropriate for sleepers who weigh under 130 pounds. Side sleepers who weigh between 130 and 230 pounds and couples with different firmness preferences might prefer the Medium version. The Firm option is likely to provide the best support for back and stomach sleepers who weigh more than 130 pounds.

Because of the GravityLux’s all-foam construction and memory foam comfort layer, most sleepers will likely feel like they’re sleeping “in” the bed rather than “on” the bed. However, the quilted polyfoam cover adds a bit of buoyancy that should prevent the “trapped in the bed” feeling sometimes associated with all-foam models.

What Is the GravityLux Made Of?

Cover Material

The GravityLux has a Tencel cover derived from eucalyptus. This fabric wicks moisture while feeling cool to the touch to help keep the sleep surface dry and reduce overheating. A 2-inch layer of polyfoam is quilted into the cover for cushioning. Its open-cell structure and an infusion of gel also help transfer heat and moisture away from the sleeper’s body.

Comfort Layers

The main comfort layer is made up of proprietary AirCell Memory Foam that contours to the sleeper’s body to relieve pressure. It also contains shock-absorbing air capsules to absorb motion and prevent vibrations from spreading across the surface of the mattress. While some types of memory foam are prone to heat retention, AirCell Memory Foam is engineered to let heat escape.

A polyfoam transition layer separates the comfort system from the core. The transition layer is zoned to promote better spinal alignment by enhancing the support near the sleeper’s hips and lower back.

Support Core

The support core consists of proprietary ATLAS Core Foam, which is a high-density polyfoam that reinforces the sleep surface while resisting sagging to provide lasting support.

Does it Isolate Motion?

Rating 4/5 (Soft, Medium), 3/5 (Firm)

The GravityLux absorbs a significant amount of motion, so sleepers likely won’t notice when their partner stirs. While the quilted cover helps dampen surface-level vibrations, the bulk of the bed’s motion isolation comes from its memory foam comfort layer. Patented AirCell Memory Foam contains air capsules to help absorb shock and limit motion transfer. This motion isolation is in line with most all-foam models.

All of the firmness options of the GravityLux isolate motion well, but the Soft and Medium versions typically perform better in this category due to their softer feels. The Firm option shouldn’t allow much motion to spread across the surface of the bed from most movements, though some vibrations could travel if one partner moves around more significantly.

Does The GravityLux Sleep Cool?

Rating 3/5

Thanks to the GravityLux’s unique materials and construction, it sleeps cooler than many all-foam models on the market. Foam mattresses aren’t usually known for their temperature regulation, especially if they contain memory foam.

The GravityLux fights the tendency toward heat retention with several temperature-regulating features. A breathable Tencel cover feels cool to the touch while transferring moisture away from the sleeper’s body. Gel-infused polyfoam is quilted into the cover, cushioning the surface while wicking away heat and allowing airflow. The memory foam comfort layer uses a patented variety of memory foam engineered to limit heat build-up.

Because the GravityLux is constructed of foam, it is unlikely to sleep as cool as the breathable hybrid models by WinkBeds. Sleepers particularly concerned with temperature regulation might also want to consider the WinkBed and the EcoCloud.

Will It Sag Along the Edges?

Rating 2/5 (Soft), 3/5 (Medium, Firm)

Sleepers could experience some sagging along the edges of the GravityLux Mattress. This is especially true with the Soft version of the bed, which will likely compress more under an individual’s weight. The Medium and Firm options should be somewhat less prone to edge sagging, but the perimeter of the bed may still feel unstable for some sleepers.

Edge sagging is a common issue with all-foam models since they do not typically have reinforced perimeters. This may make it harder to sit or sleep comfortably near the edge of the bed, effectively reducing the total usable surface of the bed. The WinkBed and the EcoCloud earn higher marks in this category thanks to their coil cores.

Is It Good for Sex?

Rating 2/5 (Soft), 3/5 (Medium, Firm)

The GravityLux Mattress is moderately conducive to sex. Its quilted polyfoam surface gives the bed a more responsive feel than some all-foam models, so it’s unlikely to significantly impede the movement of most couples. Conforming from the comfort system can also provide traction, which some couples enjoy. Since the bed doesn’t have springs, it’s virtually silent under movement, lending itself well to discrete activity.

Because of its all-foam construction, however, the GravityLux’s main drawback may be its lack of bounce. Many couples prefer a springier surface for sex, which may give the WinkBed and the EcoCloud an edge in this performance category.

What About Off-gassing?

Rating 3/5

Any new mattress may have a “new mattress” smell at first, and the same is true of the GravityLux Mattress. These smells are usually a result of the manufacturing process, and they don’t have time to air out when a mattress ships compressed.

The GravityLux’s cover is OEKO-TEX certified, and its foams are CertiPUR-US certified, so the bed’s materials have been tested for an array of potentially harmful substances. Most smells should air out within a few days if you leave the mattress in a well-ventilated space.

What Type of Sleeper Is the GravityLux Mattress Best for?

Since the GravityLux comes in three feels, most sleepers can find an option that’s comfortable for them regardless of their weight and preferred sleep position. However, getting the best balance of contouring and support requires taking these factors into account.

Side Sleepers

Side sleepers usually have sharper pressure points since their hips and shoulders dig into the bed more than other parts of their body. The GravityLux’s quilted cover and memory foam comfort layer provide ample cushioning and contouring to accommodate a side sleeper’s curves. Zoning in the polyfoam transition layer also helps prevent their hips from sinking in too deeply and pulling their spine out of alignment.

To get the right blend of cradling and support, side sleepers may want to select a firmness that corresponds to their weight. Side sleepers who weigh under 130 pounds may prefer the Soft option so that they can sink in enough for pressure relief. Those who weigh between 130 and 230 pounds will likely rest most comfortably on the Medium version.

Individuals who weigh more than 230 pounds may like either the Medium or Firm version of the GravityLux. The Medium may be a bit softer than ideal, allowing their hips and shoulders to sink in too deeply for proper spinal alignment. However, the Firm version could be slightly firmer than ideal for some, which could contribute to pressure buildup.

Combination Sleepers

The GravityLux can accommodate any sleep position, making it an excellent match for combination sleepers. Its memory foam comfort layer shapes to the body to relieve pressure, while the zoned transition layer helps keep the spine aligned by limiting midsection sinkage.

Most combination sleepers who weigh under 130 pounds are likely to prefer the Soft option, which receives excellent marks for side, back, and stomach sleeping.

Those who weigh between 130 and 230 pounds may like either the Medium or Firm version. The Medium version may be better for combination sleepers in this weight group who frequently sleep on their sides, while the Firm option can provide better support for those who favor back and/or stomach sleeping. Combination sleepers who weigh more than 230 often prefer the Firm option for its balance of contouring and support.

Back Sleepers

Each firmness option of the GravityLux Mattress can provide exceptional support and cradling for different back sleepers. Its memory foam comfort layer will gently shape to a back sleeper’s hips, reducing pressure buildup and supporting their natural spinal alignment. The transition layer’s zoning adds support to the midsection to help prevent a back sleeper’s hips from sinking in too deeply and putting a strain on their lumbar region.

Back sleepers who weigh under 130 pounds can get the support they need from any of the GravityLux’s firmness options, though the plusher feel of the Soft option may be most comfortable for them. Individuals who weigh over 130 pounds might like either the Medium or Firm version of the mattress. However, the Firm version may be more supportive of proper spinal alignment.

How Does Body Weight Impact the GravityLux Mattress's Performance?

Body weight plays a significant role in how a sleeper experiences their mattress, and the same holds true of the GravityLux Mattress. Individuals who weigh more put more pressure on the mattress, so it may seem softer to them. On the other hand, sleepers who weigh less apply less pressure to their bed, which can make it feel firmer. That means that the same mattress that seems soft to one person may feel firm to another.

As a general rule, most sleepers who weigh under 130 pounds will likely prefer the Soft version of the GravityLux, those who weigh between 130 and 230 pounds may gravitate towards the Medium or Firm version, and individuals who weigh over 230 pounds will probably favor the Firm version.

Sleeping position also influences firmness preferences. Side sleepers usually prefer a slightly softer mattress than back or stomach sleepers. If you’re on the cusp between two of GravityLux’s firmness options after taking your weight into account, you may want to make your final decision based in part on your preferred sleeping position.

Is the GravityLux Mattress Good for Couples?

Each of the GravityLux firmness options has some distinct potential benefits and drawbacks for couples.

The Soft feel has exceptional motion isolation, so a sleeper may be less likely to awaken when their partner moves. However, the Soft version’s plushness may make moving around on the bed more difficult, and the edge may not feel secure enough to allow couples to use the full mattress surface. Additionally, it may not be ideal for partners from different weight groups since it is most popular with those who weigh under 130 pounds.

Couples who want a balance between plushness and support may like the Medium option. Like the Soft version of the mattress, the Medium feel offers notable motion isolation. Thanks to its firmer feel, it should be easier for couples to move around on. The perimeter also has a more supportive feel, so couples may be able to use more of the sleep surface without avoiding the edge. As it tends to perform well for most weight groups and sleep positions, it may also be a good compromise for couples with different preferences.

The Firm option has a more supportive feel, but it shouldn’t be too hard for most sleepers. This may make it a good option for couples from different weight groups and who have different position preferences. The perimeter should be sturdy enough to allow most couples to use the full mattress surface, and the comfort layer provides some hug without significantly restricting movement. However, couples may experience slightly more motion transfer on the Firm version than they would on the Soft or Medium options.
