WinkBeds GravityLux Mattress Review

Built with thick layers of memory foam, the GravityLux mattress from WinkBeds is designed with deep pressure relief and comfort in mind. But does the construction actually pull off this cozy aim?

To find out, I personally tested the GravityLux myself, assessing everything from its build to its firmness, pressure relief, motion transfer, and bounce. After giving it a thorough once-over, I’m ready to share my expert thoughts with you!

Brand Snapshot

WinkBeds got its start in 2014, setting off to disrupt the mattress industry with high-quality beds made from eco-friendly materials. Since then, the brand has become a popular voice in the bed-in-a-box sphere, thanks to its robust line of mattresses and bedding accessories.

We’ll take a moment later on to size up the GravityLux against its mattress siblings: the Original WinkBed and the WinkBed EcoCloud. But before we do that, let’s pull back the cover and see what’s going on in the GravityLux mattress!

What is the GravityLux Made of?

As I teased in the intro, the main player in the all-foam GravityLux is memory foam… a whopping five inches, to be exact! This material is known for its body contouring and sinkage, so should provide targeted pressure relief to the shoulders and hips.

Cover – The cover is made of tencel, an eco-friendly cotton substitute that’s soft and cool to the touch.

Comfort – Up top, you’ll find 2” of gel-infused memory foam. This material has a slow response to pressure, allowing the sleeper to sink in for pressure relief at the shoulders and hips. And while memory foam has a slight reputation for absorbing and trapping body heat, the gel infusion here does a lot to mitigate this stuffiness.

Contour – Directly below the top layer of memory foam, you’ll land on yet another section of memory foam. This 3” layer extends the body contouring of the comfort layer even further into the mattress, producing a deep hug. That said, you’ll likely feel more “in” this bed than “on top” of it, which may not be great for back or stomach sleepers, but could be fantastic for those who sleep primarily on their side.

Transition – To curb the intense sinkage of the top layers, WinkBed has snuck in a 3” transitional section of poly foam. This section is mostly here to help ease the sleeper into the firmer base below.

Support – The construction wraps up with a 4” layer of high-density poly foam. This section provides the mattress with its shape and helps to support the sleeper as they sink into the bed.

Thoughts: Wow, that’s a lot of memory foam! While it may not be the best design for those who like a firm, supportive structure, it could be great for side sleepers or those after pressure relief at sensitive spots such as the shoulders, hips, or lower back.

How Does the GravityLux Mattress Feel?

Now that we’ve gone over what the GravityLux is made of, let’s figure out how it feels, starting with firmness.

As with any sort of feel factor, firmness is highly subjective, and can change a lot depending on one’s body size, shape, and weight. Therefore, I think it’s important to incorporate a few different opinions into my firmness test. The score you see below, then, is the composite of me and my coworkers’ personal firmness ratings.

WinkBed MemoryLux Firmness
I found the GravityLux to have a medium firmness

We were all pretty much in agreement about the firmness of the WinkBeds GravityLux, landing on an average rating of 6.5, which syncs up perfectly with the industry standard for medium firmness.

I personally gave the bed a 6.5 as I found its foam layers worked together to hit a nice sweet spot between pressure relief and support. Though I experienced it as fairly medium firm, some of my coworkers found it to be a touch softer or firmer, and that really has more to do with how individual sleepers experience memory foam.

Testing out the WinkBed GravityLux

At 5’10” and 190 lbs., I sank through the memory foam layers quickly, and interacted pretty directly with the poly foam layers. Lighter sleepers may find that they mostly stay within the memory foam layers, while heavier folks may plunge straight through them. With memory foam, it’s always important to give your body a few minutes to adjust to the structure as the material conforms to your body.

Regardless, thick layers of memory foam like this are going to work best for side or side/combo sleepers. Back and stomach sleepers may not get enough support from such gentle top layers, which we’ll explore in more detail below.

Testing the GravityLux Mattress

To get an even better sense of the GravityLux, let’s run it through a few of my favorite tests for Pressure Relief and Motion Transfer. That way, you’ll be able to see with your own eyes what I’m talking about.

Pressure Relief

When assessing a bed’s pressure relief (aka it’s ability to alleviate tension at the shoulders, hips, and lower back), I like to use a good ol’ fashioned pressure map. Basically, I roll this device out, hop aboard, and let the device track the force my body exerts on the structure in real time. Areas of low pressure are shaded in blue and areas of high pressure are shaded in red.

Back – Stretching out on my back, I felt some nice pressure relief as the top layers of memory foam filled in space at my lumbar region. While this comfort was satisfying, I usually like a little more support for back sleeping, and was also struck by how difficult it was to move around and change positions.

Side – As we discussed earlier, side sleeping was super pleasant on the GravityLux. I could feel my hips and shoulders sinking deeply into the mattress, which helped to alleviate tension at these sensitive spots.

Stomach – Unfortunately, the comfort didn’t really translate onto my stomach. Though you can’t see it on the map, I could feel my hips sinking out of line with my shoulders, which is a big no-no for those who sleep primarily in the prone position. These sleepers will want a firmer structure, which will support a more neutral spine alignment.

Motion Transfer

For my next test, I’m going to take a look at the GravityLux’s motion transfer, or the amount of movement detectable from one side of the bed to the other. This section will be particularly pertinent for those who sleep with a partner, as it’ll clue you into the disturbances you’re likely to feel as they toss and turn in the night.

To illustrate this motion transfer, I dropped a 10 lb. steel ball from heights of 4 inches, 8 inches and 12 inches and measured the disturbance it caused: the bigger the lines, the bigger the disturbance.

These are solid motion transfer results, which tells me you shouldn’t be too bothered by your bed mate’s nighttime movements. I’m not too surprised by this, as memory foam is traditionally very effective at dampening motion. If both you and your partner like the feel of this contouring material, I think the GravityLux could be a great fit!

GravityLux Vs.

At this point, we know the GravityLux inside and out, but how does it compare to the other beds WinkBeds sells? To find out, I’m going to compare it to two of its mattress siblings: the Original WinkBed and WinkBed EcoCloud.

Original WinkBed

  • The WinkBed is a hybrid mattress with a sturdy innerspring feel.
  • It also comes in three different firmness options (as well as a plus version for heavier folks).
  • The medium firm WinkBed is a good choice for combo sleepers, as its high mobility makes it easy to change positions.
  • Pricewise, it’s starting cost of $1,049 it’s slightly less expensive than the GravityLux’s $1,099 starting price.
  • For more, check out my full WinkBed review.

WinkBed EcoCloud

  • Like the WinkBed, the EcoCloud is a hybrid mattress, though it features a gentler construction of organic cotton, latex, and pocketed coils.
  • The resulting construction is super bouncy, which makes it a nice fit for combo sleepers.
  • I also think it could be a great bed for eco-friendly sleepers, as its materials are all-natural and organic.
  • When it comes to price, the EcoCloud is the most expensive of the three, starting at $1,299.
  • Check out my full review of the EcoCloud for more information

Should You Buy the WinkBed GravityLux Mattress?

After going over its construction, sussing out its feel, and comparing it to a few other WinkBed mattresses, it’s time to decide: Is the GravityLux right for you? I can’t say for sure, but I can leave you with a few final thoughts to help you get there on your own.

The WinkBedsGravityLux has thick layers of memory foam to provide great pressure relief and the classic contouring feel of sinking into bed. 


  • First and foremost, this bed is going to be great for anyone who loves memory foam. With 5” of the stuff up top, the GravityLux really embodies the material’s classic feel of body contouring and sinkage.
  • These attributes could be particularly nice for side and side/combo sleepers who need to sink deeply into their mattress.
  • Truly, anyone after pressure relief at the shoulders and hips could find a lot to love in the GravityLux.


  • Unfortunately, all this memory foam does mean that the GravityLux isn’t very bouncy, which could be a dealbreaker for those after a buoyant lift.
  • It’s also got weak edge support, so may not be the best fit for sleepers who need to use the entire surface area of the bed.
