When I tried the original GhostBed mattress, I enjoyed my experience. I was especially impressed by its value and found it to be a great match for back and stomach sleepers.

So when I heard about the GhostBed Flex, I was very excited to try it out. Unlike the original GhostBed, the Flex is a hybrid mattress with gel memory foam and high-grade support coils.

Having reviewed the original GhostBed and many other hybrid mattresses, I was interested to see how the Flex would compare. This unbiased GhostBed Flex mattress review will cover everything consumers should know, including a full breakdown of the construction, the pros and cons, comfort, support, motion isolation, edge support, breathability, durability, and much more.

GhostBed Flex Mattress Firmness And Feel

When shopping for a new mattress, it’s critical to consider a bed’s firmness and feel. These factors have a big impact on whether a mattress will feel comfortable for different types of sleepers.

How Firm Is The GhostBed Flex?

The GhostBed Flex felt like a 6.5/10 in terms of firmness. You have a soft comfort layer over some firmer, more supportive coils. Combined, this gives the mattress a medium firmness.

Sleeping On The GhostBed Flex Mattress

Back sleepers should enjoy the GhostBed Flex. The individually-wrapped coils will support the sleeper while the top layers should conform to the body shape.

Side sleepers should feel good pressure relief and overall comfort. Because of the 4” of comfort material, side sleepers should sink into the mattress and feel almost no pressure on shoulders and hips.

We think that the GhostBed Flex mattress is probably too soft for stomach sleepers as they will most likely need more support.

What Does The GhostBed Flex Feel Like?

The GhostBed Flex has a hybrid feel with some of that classic memory foam feel on top. The gel memory foam isn’t very quick to respond and has almost no bounce.

That being said, we didn’t have trouble moving around on the mattress. Overall, you should get the feeling of memory foam and coils in one mattress.

Average Weight Sleepers – 130 lb – 230 lb

Back sleepers who are average weight should enjoy the GhostBed Flex most as the individually-wrapped coils will provide an appropriate amount of comfort and support. Average weight people who sleep on their side should feel good pressure relief and overall comfort.

The GhostBed Flex is not one of the best mattresses for stomach sleepers who are average weight. These people will probably need much more support.

Heavyweight Sleepers – Over 230 lb

For heavyweight sleepers, the GhostBed Flex is going to feel much firmer because you will sink through the top comfort layer. This is especially true for heavyweight side sleepers who may experience too much pressure on their shoulders and hips. Heavier stomach sleepers may find the GhostBed Flex lacks overall support.

However, heavyweight back sleepers should feel really well-supported on the GhostBed Flex mattress as their hips should sink in just the right amount while the top layer should support the lumbar area.

Lightweight Sleepers – Under 130 lb

Lightweight side sleepers should feel really comfortable on the GhostBed Flex mattress as they should experience the soft contour of the top comfort layer as well as great pressure relief on the shoulders and hips. Lightweight back sleepers may also really enjoy the GhostBed Flex as they should feel the mattress contour and support the lumbar region of the spine really nicely.

Stomach sleepers who are lightweight probably won’t be as comfortable as they may not feel enough support for their lower back

GhostBed Flex Mattress Construction

It’s time to look under the cover of the GhostBed Flex mattress and see exactly what’s inside. We’ll look at each layer one by one and see what it does for the overall performance of the GhostBed.

Cover

The GhostBed Flex has a plush quilted cover that is instantly cool to the touch, allowing the mattress to feel more breathable so it won’t trap your body heat. The cover is soft, supple, and gently soothing.

The cover of a hybrid mattress

Comfort Layers

Below the cover is 1” of cooling fiber for pressure relief. Then there are two 1” layers of gel memory foam, which provide great pressure relief and body contouring. This is followed by 1” of Ghost Flex Soft transition foam, which acts as a buffer between the comfort and support layers.

Support Layer

For support, there are 8” of individually-wrapped and reinforced support coils, which are highly supportive, breathable, and durable. Finally, there is a 1” layer of high-density support foam that the support coils can rest on.

Mattress Height

The mattress is 13” tall and features a complex construction of coil and foam layers.

GhostBed Flex Mattress Performance

Now that you know what the GhostBed Flex is made of and what it feels like, it’s necessary to understand how the mattress performs before making any purchase decision. Let’s see how the GhostBed Flex did!

Sleeping Hot Or Cold

Those who sleep hot should enjoy the GhostBed Flex mattress. The coils promote airflow throughout the mattress and the gel memory foam dissipates heat, so people shouldn’t be sleeping hot on this mattress.

Motion Transfer

The GhostBed Flex handles motion transfer well thanks to its gel memory foam. This makes it a good mattress for couples who don’t want to be disturbed by their partner’s movements.

Edge Support

The GhostBed Flex is a hybrid mattress with a reinforced edge where the coils are actually firmer toward the edge of the mattress. You should feel secure when sitting on the edge of the GhostBed Flex mattress because of its solid edge support.

Durability

The GhostBed Flex is fairly durable. The coils in the mattress make the GhostBed Flex more durable than many all-foam mattresses. This mattress should be a good investment because it should last for many years.

Off-Gassing

You may experience a faint smell when first unboxing your new GhostBed Flex mattress. No worries. The odor is harmless and should dissipate quickly. The materials in the GhostBed Flex are CertiPUR-US certified and contain no harmful chemicals.

Noise

Although the GhostBed Flex includes coils in its construction, we didn’t observe any notable noise when we rolled around on the bed. This should be a quiet mattress to sleep on.

Sex

When looking for the best mattress for sex, couples typically look for good bounce, lack of noise and ease of movement. The GhostBed Flex and its commitment to both comfort and support should make it a good mattress for sex.

SUMMARY

The GhostBed Flex has a lot to offer, and while it does cost more than the other GhostBed mattresses, it should be a great investment. Most back sleepers, side sleepers, and hot sleepers should find what they need on the Flex, but stomach sleepers or those who want a very firm or very soft mattress might want to look elsewhere.

GhostBed Flex Mattress Company Policies

In addition to learning all about the mattress, it’s important to understand a company’s policies before making a final decision.

Warranty

The GhostBed Flex mattress is covered by a 20-year warranty. However, certain regulations and fees may apply after 10 years have passed. Learn more about the warranty on GhostBed’s website.

Sleep Trial

The GhostBed Flex offers a 101-night sleep trial and suggests taking 30 to 60 nights to make your decision. This gives you time to try the mattress in your own home and ensure that it meets all of your sleep needs.

Return Policy

If you ultimately decide that you don’t love the GhostBed mattress after a minimum of 30 nights, you can visit the company’s Return Request page for a free and easy return process.

Complaints

Although the GhostBed Flex is advertised as a cooler mattress, heavyweight sleepers and couples have claimed that the GhostBed Flex sleeps too hot for their comfort. If you are a hot sleeper, you may want to look at our list of cooling mattresses for hot sleepers instead.

How Does The GhostBed Flex Compare To Other Mattresses?

Searching for a new mattress can often be overwhelming. Yet, it’s important to compare different mattresses to one another before making a final decision. Let’s see how the GhostBed Flex compares to the Casper Wave Hybrid.

Compare GhostBed Flex to other mattresses on our mattress comparison page.

GhostBed Flex Vs Casper Wave Hybrid Mattress Comparison

GhostBed and Casper are both mattress companies that have expanded beyond their original mattress and now offer a selection of hybrid and all-foam mattresses. If you’re looking for a high-quality hybrid mattress, you may be stuck between the GhostBed Flex and the Casper Wave Hybrid, so we’ll compare the two to help you decide which is best for you.

The GhostBed Flex and Casper Wave Hybrid mattresses are very similar. Both have a cooling cover, followed by memory foam for comfort and coils for support. However, the Casper Wave Hybrid does offer a unique feature of zoned support which allows the mattress to be firmer towards the center and softer towards the head and foot of the mattress. The zoned supports makes the Casper Wave Hybrid an ideal option for sleepers who are in need of more support under their lumbar area.

The firmness ranking for these mattresses will depend a bit on the weight of the sleeper in question, but we ranked both the GhostBed Flex and the Casper Wave Hybrid a 6.5/10.

The most notable difference between the GhostBed Flex and Casper Hybrid is the price. The Casper costs about $800 more than the GhostBed.

Who Should Get The GhostBed Flex?

  • Couples who are looking for a mattress that handles motion transfer well.
  • Back or side sleepers who want a balance of support and comfort.
  • Hot sleepers who are looking for a mattress that sleeps cool.

Who Should Get The Casper Wave Hybrid?

  • People who are in need of more support under their lumbar area.
  • Those looking to purchase a mattress that will be a good long-term investment.
  • Folks who like a balanced foam feel that mixes pressure relief with responsive support
