GhostBed launched in 2015 on a mission to provide its customers with “supernatural comfort.” Its luxury hybrid mattress model, the GhostBed Flex, puts emphasis on springy support and cooling, while also providing pressure relief and comfort.
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.

GhostBed Flex Mattress Review Video
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, cushioning, 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.
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.
- If you like to feel more “on top” of the bed and have a firm feel, then this probably isn’t the best pick for you. I feel a decent amount of sinkage when I lay on it.
- Although a great deal for its materials, this mattress at full price does run on the more expensive side. Budget shoppers may want to check out our favorite cheap mattresses instead. However, keep in mind we have coupons throughout this mattress review to help save you money.
How Firm is the GhostBed Flex Mattress?
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.
A few coworkers and I gave this bed a try to test its firmness level, so the score you see below will be an average of our opinions.
I ultimately gave this mattress a 5.5 out of 10 on the mattress firmness scale. Since we consider 6.5 to be medium firm, that means the GhostBed Flex is a little softer than average. When I first lay down on the bed, I was immediately hugged by its top memory-foam layer and quilted cover. Overall, it has a doughy, cushiony feel that contours around your body and makes you feel more “in it” than “on it.”

GhostBed Flex Mattress Performance
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. I’ll also share how it performs for sleepers of different weights.
Testing the GhostBed Flex Mattress in Different Sleeping Positions
Depending on your body type and preferred sleeping position, the GhostBed Flex is going to have a unique feel for you. Take a look at how I think it works for three major weight classes.
Is the GhostBed Flex a Good Mattress for Light Sleepers (Under 130 pounds)?
- Light Back Sleepers – I’d heartily recommend this mattress to lightweight back sleepers. These sleepers should find their backs supported and their joints cushioned.
- Light Side Sleepers – I think the Flex works for most light side sleepers. However, if you suffer from hip or shoulder pain, I’d opt for a plusher mattress that will offer a bit more pressure relief. Since lighter sleepers don’t sink into mattresses as deeply, they tend to need a softer bed than average weight sleepers.
- Light Stomach Sleepers – The Flex is a bit too soft for light stomach sleepers. These sleepers need a firmer mattress — one that’s at least a 7 out of 10 on the firmness scale — to feel comfortable.
Is the GhostBed Flex a Good Mattress for Average Weight Sleepers (130 – 250 pounds)?
- Average Weight Back Sleepers – These sleepers should be quite happy with the GhostBed Flex. It’s supportive and would be great for back sleepers who appreciate some contouring and plushness.
- Average Weight Side Sleepers – I also like this bed for average weight side sleepers. They should sink in just enough to keep their spine in a neutral alignment and get the cushiony relief they need at different pressure points.
- Average Weight Stomach Sleepers – These sleepers should opt for a firmer mattress that will help prevent their hips from sinking too far into the mattress, which will throw their spines out of alignment. I’d recommend they check out our roundup of best mattresses for stomach sleepers instead.
Is the GhostBed Flex a Good Mattress for Heavy Sleepers (over 250 pounds)?
- Heavy Back Sleepers – A lot of heavy back sleepers should feel enough support and comfortable on the GhostBed Flex.
- Heavy Side Sleepers – I think these sleepers will sink too far into the GhostBed Flex and not get the pressure relief they need. Instead, I’d recommend looking at a mattress specifically designed for heavy people.
- Heavy Stomach Sleepers – These sleepers will likely want to look for a more supportive bed to better elevate their hips and promote spinal alignment.
GhostBed Flex Mattress Pain Relief Performance
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. A pressure map uses heat mapping technology to track where pressure’s building across my body on a bed. The graphic below shows areas of low pressure in blue and green and areas of high pressure in red and orange.
Back Pain — While sleeping on my back and side, you can see my back is mainly all blue, which indicates low pressure. This means that this bed is unlikely to cause or worsen back pain for these sleepers. However, this is going to be too soft of a mattress to alleviate back pain for stomach sleepers.
Shoulder Pain— I’d say this is a fine mattress for most side and back sleepers who suffer from shoulder pain. However, if you sleep on your side and suffer from severe shoulder pain, you might want to opt for a plusher mattress. Stomach sleepers with shoulder pain will want to look for a firmer mattress. Side sleepers and stomach sleepers with shoulder pain can find alternatives on our best mattresses for shoulder pain page.
Hip Pain – Most side and back sleepers with hip pain should feel comfortable on the GhostBed Flex. Similarly to shoulder pain, I’d recommend side sleepers with severe hip pain to look for a plusher mattress. This mattress will be too soft for stomach sleepers with hip pain, as it won’t keep them elevated enough to keep their spine in alignment.
GhostBed Flex Mattress Performance for Couples
If you sleep with a partner, you’re going to want to weigh a few additional factors before buying a new bed. You’ll want to know if it absorbs movement well, is good for sex, has sturdy edges, and whether or not it’s cooling (two bodies in a bed tend to be hotter than one). Take a look at how the Flex performed on our tests for these factors.
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 especially so for those who share their bed with a partner or pet.
To illustrate motion transfer, I dropped a 10-pound 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 responsive and easy to move around on, so I assumed it wouldn’t do well on this test. But the gel memory foam layers on top of the bed did a good job absorbing motion across the mattress.
Sex
I think the Flex is a good mattress for sex. It performed well on our bounce test (high bounce), which shows that it’s easy to move around on this bed. You won’t feel “stuck” in this mattress.
Cooling
The Flex sleeps really cool! That’s thanks to all the cooling technology GhostBed made this mattress with. Not only does it have a cooling cover to help wick away moisture and dissipate body heat, but it’s comfort layers are made from gel memory foam and a latex-like foam that are both quite breathable.
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 has solid 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. The company calls it ghost bounce 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 make the bed durable and promote airflow to keep the mattress cool.
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.
GhostBed Flex Mattress Unboxing and Off-Gassing
Since the GhostBed Flex is a bed-in-a-box mattress, you will have to unbox it at home. I’d recommend waiting at least 24 hours after unboxing this bed to let it fully decompress and release any trapped gasses.

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 responsiveness 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 plush feel of this GhostBed and how cool it sleeps. 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
I think a lot of heavier sleepers (over 250 pounds) will find this mattress much softer and less supportive than I did. They’ll want to find a bed with a little more support.
I also don’t think stomach sleepers will find the comfort they need on this mattress. These folks might do better on one of our best firm mattresses.

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
- 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 it 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.

GhostBed Flex vs Casper Hybrid
- 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 our full Casper Hybrid mattress review.

Other Models from GhostBed
GhostBed offers other models, which I’ll compare some of them 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
- 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.

GhostBed Flex vs GhostBed 3D Matrix
- The 3D matrix is also a hybrid model and feels softer than average. 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.

GhostBed Flex vs GhostBed Luxe
- 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 and is closer to a medium-firm feel 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.
