GhostBed Flex Mattress Review

GhostBed launched in 2015 on a mission to provide its customers with “supernatural comfort.” Its hybrid mattress model, the GhostBed Flex, puts emphasis on springy support and cooling, and this bad boy is a bouncy option that could be perfect for folks who need a little lift while they sleep.

But is the bed actually comfortable? To find out, I tested it myself, assessing its firmness, motion transfer, and edge support to determine who would benefit from its unique design… and who wouldn’t.

Curious to see whether or not this mattress could be the one for you? Keep reading my GhostBed Flex mattress review below! Short on time? Zoom on over to my review summary.

Is the GhostBed Flex a Good Mattress for You?

Before we get into the details on this bed, I want to give you an overview of who it might work best for. Take a look at the lists below to learn more.

Who I recommend the GhostBed Flex mattress for

  • I really like this bed for back and side combination sleepers. It offers a mix of pressure relief and mobility that could be great for them.
  • If you’re a hot sleeper, you might enjoy that the Flex sleeps cool. Its cooling cover and gel-infused foams make this a very breathable mattress.
  • The Flex could be a nice bed for couples, you shouldn’t feel overly disturbed by a restless partner on the Flex, and its medium-firm feel could accommodate several different sleeping positions.

Who I don’t recommend the GhostBed Flex mattress for

  • This bed isn’t going to be a slam dunk for stomach sleepers, who tend to need firmer structures for even spinal alignment. These folks may want to check out our best mattresses for stomach sleepers to find a better fit.
  • The Flex also isn’t quite supportive enough for heavier folks (over 250 lbs), who may prefer one of our best mattresses for heavy people.
  • Finally, if you’re looking for an extra firm or extra soft feel, this medium-firm mattress may not work for you.

What Does the GhostBed Flex Mattress Feel Like?

Now that you know the basics, let’s dive in and discuss how this bed actually feels. Keep in mind that feel is subjective, and a mattress will feel different to you depending on your body weight, shape, and preferred sleeping position.

For reference, I’m a lighter sleeper who prefers to sleep on her side, so this mattress may feel firmer to me than it would to you. A few coworkers also gave this bed a try, so the score you see below will be an average of our opinions.

The GhostBed Flex on the mattress firmness scale.

I gave this mattress a 6.5 out of 10 on the mattress firmness scale. That means this mattress is a true medium-firm bed. When I first lay down on the bed, I was immediately hugged by its top memory-foam layer and quilted cover. This immediate pressure-relief and softness make this bed a great option for side sleepers. It should cushion their pressure points in this position, which will help them avoid stiffness over time.

After I sank through that layer I was met with firmer, springy support from a latex-alternative layer and pocketed coil support system. Despite the initial hug-like feeling, I didn’t feel stuck in this mattress at all. This means combination sleepers should really enjoy this bed.

This mattress’s blend of pressure relief and support should also appeal to back sleepers. If you’re someone who likes gentle contouring around your lower back, you should like this mattress. On the other hand, stomach sleepers will need a firmer feel to be comfortable.

Testing the GhostBed Flex Mattress

To give you a better idea of whether or not the Flex could be the right new mattress for you I ran a few tests. Below, I’ll discuss the pressure relief, edge support, and motion transfer on the GhostBed Flex to give you an idea of how it might feel to sleep on this bed.

Pressure Relief

Pressure relief, or how a mattress is going to relieve pressure at sensitive spots along the body (such as the shoulders, hips, and lower back) is an important measure of a mattress’s comfort level.

To demonstrate the Flex’s ability to alleviate tension at these spots, I stretched out on a pressure map, which recorded how my body was reacting to the bed in real time. The graphic below shows areas of low pressure in blue and green and areas of high pressure in red and yellow.

The Flex's pressure map results.

Back — On my back, my weight was pretty evenly distributed across the surface of the mattress. I could feel the top foam layers filling in the space at my lumbar region, which provided some nice pressure relief to this area. This could be a nice perk for sleepers who struggle with back pain. The all-blue pressure map above reflects this well.

I like the Flex for back sleepers.

Side — Turning onto my side, I continued to feel nice relief. My shoulders and hips felt hugged by the bed’s memory foam layers, which is something that I see as a big plus for the side sleepers out there. There’s a little green on the pressure map, but I don’t think that’s anything to worry about.

Side sleeping on the GhostBed Flex
The GhostBed Flex felt comfortable on my side.

Stomach — I didn’t feel super comfortable on my stomach. The softness of the comfort layer caused my hips to sink out of line with my shoulders, which created some bend in my spine. Stomach sleepers will likely need a firmer mattress that supports a healthier spinal alignment. One of our best innerspring mattresses could work better for them.

Motion Transfer

In this next test, I measured the bed’s motion transfer, or the amount of movement detectable from one side of the mattress to the other. Motion transfer is an important factor for all sleepers, but perhaps especially so for those who share their bed with a partner or pet.

To illustrate 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.

I was surprised by how well the Flex isolated motion! This hybrid mattress is pretty bouncy and responsive, so I assumed it wouldn’t do well on this test. But the gel memory foam layers on top of the bed did a great job absorbing motion across the mattress.

It’s rare for a bed to be great for both combination sleepers and couples, and the GhostBed Flex fits this bill. If you’re looking for one of the best hybrid mattresses to share with a partner I’d recommend checking it out.

Edge Support

My last test measured the edge support on the GhostBed Flex. Edge support is a measure of whether or not you’ll be able to sleep all the way on the edge of the bed without the sides collapsing.

The Flex has reinforced edges, so it had pretty decent edge support. I have tested mattresses with stronger edges than the Flex, but this hybrid mattress does have a stronger edge than some all-foam bed options.

What is the GhostBed Flex Mattress Made Of?

Next up, let’s take a look inside the GhostBed Flex to see what makes it tick. This 13-inch mattress employs cooling technology and CertiPUR-US® Certified foams to achieve a bouncy, pressure-relieving feel. Keep reading below to learn more about each layer.

Cover — The GhostBed’s quilted cover is made with special cooling fiber that draws body heat away from the sleeper. It’s also quilted with some plush gel memory foam to offer some immediate pressure relief.

Comfort Layer — Below the cover you’ll find a top layer of gel memory foam to offer additional body-contouring and some motion isolation. Couples and side sleepers should enjoy this layer’s soft feel.

Transition Layer — Next up is a latex-like layer of transition foam. Like latex foam, this foam is bouncy and cooling. It helps lift the sleeper up and out of the structure, and eases them down onto the pocketed coil layer below.

Support Layer — The bulk of the mattress is a pocketed coil system. These support coils bring some fantastic bounce to the Flex and help keep the sleeper more on top of the bed. While a lot of sleepers may like this extra lift, I think it could be especially beneficial for combination sleepers who need to change positions with ease.

Base Layer — The base of the mattress is made of high-density support foam. This section acts as a foundation for the pocketed coils to bounce off.

My Final Thoughts About the GhostBed Flex Mattress

The question of the hour: Is the GhostBed Flex mattress the right bed for you? Let me provide you with a few final thoughts to help guide you toward your final decision.

My favorite things about the GhostBed Flex mattress

I really appreciate the combination of bounce and motion isolation in the GhostBed Flex. This unique combination makes it a great fit for both couples and combo sleepers, which can be a rare find!

I also really enjoy the medium-firm feel of this GhostBed. This feel should be comfortable to many different types of sleepers, which is another great perk for couples.

Finally, I appreciate that this mattress is more cooling than a traditional memory foam mattress. Side sleepers won’t have to sacrifice pressure-relief for cooling on this hybrid mattress. And back sleepers should get some nice pressure-relief at the lower back. All in all, it’s a great option for hot sleepers looking for a little body-contouring.

My GhostBed Flex mattress complaints

That said, I do wish the GhostBed offered just a little more support. I think heavier sleepers (over 250 lbs) will find this mattress much softer and less supportive than I did. These folks might do better on one of our best firm mattresses.

And the GhostBed’s cooling cover can be a bit slippery. Some customers have noticed that their fitted sheets don’t stay on the Flex. A solution I’d recommend for that problem is using a mattress protector, which could provide your sheets with some extra traction.

Ghostbed Flex Mattress Vs

To wrap up this review, I’m going to take a moment to compare the GhostBed Flex to one of its external competitors and a few of GhostBed’s other models. First up, I’ll compare it to the Bear Hybrid.

GhostBed Flex vs Bear Hybrid

Bear Hybrid Cover
The Bear Hybrid mattress.
  • Like the GhostBed Flex, the Bear Hybrid is a bed-in-a-box hybrid built with layers of foam and pocketed coils.
  • The Bear features latex over memory foam, so has a slightly firmer feel than the GhostBed Flex.
  • The Bear Hybrid offers great mobility, but the Flex feels just a little bouncier.
  • Price-wise, the Bear Hybrid is a little cheaper than the Flex, which could be a perk for budget shoppers.
  • For more on the Bear, check out the full Bear Hybrid mattress review.

GhostBed Flex vs Casper Hybrid

Casper Hybrid
The Casper Hybrid mattress.
  • Like the Flex, the Casper Hybrid is a bouncy and supportive hybrid mattress.
  • The Casper Hybrid is also a medium-firm bed, but it uses less memory foam than the GhostBed Flex. So side sleepers might get more pressure relief on the GhostBed.
  • The zoned support system in the Casper Hybrid could be especially helpful for folks who struggle with back pain.
  • Interested in the Casper Hybrid? Take a look at my full Casper Hybrid mattress review.

Other Models from GhostBed

GhostBed offers three other models, which I’ll compare to the Flex below. Though these beds do share some attributes (gentle foam, emphasis on cooling), I consider them to be pretty distinct products.

GhostBed Flex vs Original GhostBed

GhostBed
The original GhostBed mattress.
  • Unlike the Flex, the Original GhostBed is built entirely of foam (including aerated latex, memory foam, and high-density poly foam).
  • The original mattress has a fairly balanced feel, but is a bit less bouncy than the Flex.
  • Notably, the Original is much less expensive than the Flex, which could be a deciding factor in your mattress purchase.
  • For more, take a peek at the full GhostBed mattress review.

GhostBed Flex vs GhostBed 3D Matrix

GhostBed 3D Matrix
The GhostBed 3D matrix mattress.
  • The 3D matrix is also a hybrid model, but it feels softer than the Flex. This could be a nice perk for side sleepers.
  • The Matrix uses a special gel polymer layer to be even more cooling than the Flex, so hot sleepers should definitely check it out.
  • Like the Flex, the 3D matrix isolates motion really well, so it could be a great pick for couples.
  • Find out more in my full GhostBed 3D Matrix mattress review.

GhostBed Flex vs GhostBed Luxe

The GhostBed Luxe
The GhostBed Luxe mattress.
  • As the name implies, this mattress is the brand’s luxury model, so it features plenty of body-contouring memory foam.
  • This all-foam mattress feels firmer than the Flex, which could be a bonus for back and combo sleepers who like a firmer feel.
  • Like the Flex, the Luxe is a cooling mattress.
