Pros
Cons
The GravityLux is an all-foam mattress from WinkBeds, a company that handmakes its mattresses in the USA. The GravityLux includes a combination of memory foam and adaptive polyfoam that is designed to provide strong all-around performance.
The GravityLux is 11 inches tall and comes in three firmness options: soft, medium, and firm. On our firmness scale of 1 to 10, these correspond to firmness levels of medium soft (4), medium (5), and firm (7), respectively.
We took a closer look at the GravityLux in our Test Lab, and our expert team rated its performance in a host of categories. In this review, we go over the test results and explain other important details about the construction and pricing of the WinkBeds GravityLux Mattress.

Answer a few questions to find the right mattress for your unique needs
To test the GravityLux Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

Talks in sleep (like a lot)
It was refreshing to sleep on the GravityLux, which doesn’t suffer from some of the biggest drawbacks of other all-foam beds. I appreciated that it stayed cool and felt sturdy around the edge of the mattress.

I liked the firm model of the GravityLux, which felt most supportive to me when sleeping on my side. The foams gave just the right amount of cushioning to my lower back without sinking or sagging beneath me.

Showers before bed
As a side sleeper, I liked how the foam layers cradled my hips and shoulders to prevent impact or pressure buildup. For me, the medium firmness option was the most comfortable.

We found that the GravityLux works well for side sleepers, but getting optimal support requires choosing the right firmness level.
Side sleepers need a mix of cushioning for their hips and shoulders as well as sturdiness to keep them from sagging too far into the mattress. Based on our test results, side sleepers under 130 pounds preferred the medium soft (4) model, those between 130 and 230 pounds liked the medium (5), and those over 230 pounds got the best results from the firm (7).
In our testing, back sleepers gravitated toward the firm (7) model of the GravityLux, which offered them the best mix of comfort and spinal support.
Back sleepers usually prefer mattresses with an even surface that supports their natural spinal alignment. The firm (7) GravityLux provides a level plane but also has a touch of cushioning for the lumbar spine. This earned it the highest marks among most back sleepers, although some under 130 pounds preferred the medium (5) version.
The firm (7) model of the GravityLux was far and away the most highly rated option by stomach sleepers in our testing.
Stomach sleepers typically require a firm mattress surface that can support their abdomen and keep it in line with the rest of their spine. The firm (7) version of the GravityLux was the only firmness option that consistently provided that level of support to stomach sleepers regardless of their body weight.

“The GravityLux didn’t absorb all motion, but it had enough motion isolation to keep me from being bothered by movement on the mattress.” – Colin
Thanks to its two-layer foam comfort system, the GravityLux absorbs a significant amount of motion when there’s movement on the mattress. Because it permits more sinkage into the foam, the medium soft (4) model got the highest scores for motion isolation in our testing.
Based on our findings, most co-sleepers should be able to sleep peacefully without being disturbed when their bed partner moves. However, people who are very sensitive to being awakened might do better with the medium soft (4) or medium (5) firmness options.

Medium: 8 / 10
Firm: 7.5 / 10
“The foams in the comfort system are surprisingly balanced. They eliminated sharp impact with the mattress but didn’t feel excessively soft.” – Brad
We found that pressure relief was one of the GravityLux’s biggest strengths.
The gel-infused polyfoam quilted into the cover gives the surface a touch of plushness. The memory foam layer provides deeper contouring, adapting its shape to match the sleeper’s body and take pressure off their hips and shoulders. The transition layer prevents excessive sinkage around the midsection, balancing the GravityLux’s strong contouring with stable support.
That said, finding the right firmness option to match your sleeping position, body weight, and comfort preferences will help determine exactly how well this mattress helps you maintain a healthy spinal posture.

Medium: 7.5 / 10
Firm: 8.5 / 10
“On the firmer models of the GravityLux, I experienced very little heat buildup. Maybe some hot sleepers would still feel too warm, but most people will find that they can avoid overheating on this mattress.” – Jackson
Since the GravityLux uses two layers of breathable foam, it sleeps cooler than many all-foam models.
The Tencel cover is moisture-wicking and breathable, and the top layer of polyfoam resists excess heat buildup. The specialty memory foam is also designed to promote steady airflow.
The softest model retains a bit more heat because of its increased contouring around the skin, but the medium (5) and firm (7) models can be comfortable even for hot sleepers.
Soft: 6.5 / 10
Medium: 7.5 / 10
Firm: 8 / 10
“As you would anticipate, the foam compresses more around the perimeter of this mattress, but it’s not very pronounced. For me, that meant a stable and supportive edge.” Colin
For an all-foam mattress, the GravityLux has strong edge support. It’s not quite on par with most innerspring and hybrid beds, but the perimeter is dependable, especially on the medium (5) and firm (7) models.
Our testing found that most people could lie down or sit near the perimeter without feeling any pronounced foam sinkage. However, the medium soft (4) model clearly had the least robust edges.
Overall, the GravityLux’s edge support should allow most people to use the full surface of the bed.

The GravityLux Mattress is 11 inches tall and available in three firmness options: medium 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 and soft to the touch. Quilted into the cover is a layer of gel-infused polyfoam, which adds both cushioning and responsiveness.
Next, a layer of memory foam, known by WinkBeds as AirCell foam, adjusts to the sleeper’s weight to relieve pressure around joints and support the spine. Microscopic air capsules in the foam are engineered to help absorb motion while permitting more air circulation than standard memory foam.
The next layer is made of polyfoam that is reinforced in specific zones to better support areas like the midsection and hips. Beneath that, the bottom layer is a dense polyfoam that serves as a durable and sturdy base.

The GravityLux Mattress is slightly higher in price than the average all-foam mattresses, but its price is in line with other luxury models made with high-quality materials. It is available in all six of the standard mattress sizes.
The GravityLux is sold through the WinkBeds website and can be shipped to addresses in the contiguous U.S. The WinkBeds mattress lineup can also be found in around 20 showrooms across the United States.
The GravityLux ships for free within the contiguous United States. It arrives compressed in a box that is delivered to your front door. It normally takes around two weeks for the mattress to arrive.
After delivery, you simply need to bring the box to your bedroom and carefully remove the packaging so that the mattress can decompress and regain its complete size. Be aware that it may take two people to lift and move the box, especially if you buy a larger mattress size.
WinkBeds does not currently offer any White Glove services for mattress installation or haul-away of an old mattress.
The GravityLux Mattress comes with a 120-night sleep trial. You have to keep the mattress for 30 nights, but after that, you have another three months to decide if the mattress is to your liking.
If you’re not satisfied, you can request a return, and WinkBeds will pick up the mattress and give you a full refund.
The GravityLux Mattress has a lifetime limited warranty that protects against defective materials or manufacturing. It does not cover damage caused by negligence, accidents, or improper use. If a mattress is found to be defective, WinkBeds will replace it at no charge.
