GhostBed Flex Mattress Review

Materials: Foam and coils

Firmness: 6.5

Warranty: 25 years

Trial Period: 101 nights

Price Range: $1,145-$2,700

The Mattress Nerd’s Take: If you’re in the market for an innovative, yet affordable hybrid mattress then the GhostBed Flex may be for you. With gel-cooling technology, the comfort of memory foam, and a durable innerspring coil layer, the GhostBed Flex can accommodate many different types of sleepers. The GhostBed Flex features great edge support and individually wrapped coils which reduce motion transfer, making this an best mattress for couples. But still, the GhostBed might not work best for stomach sleepers and some back sleepers who need something firmer and more supportive.

Who is GhostBed Flex Best For?

Lightweight (< 130 lbs): 4 2 3
Average weight (130 – 230 lbs): 3 2 4
Heavyweight (> 230 lbs): 4 2 4

1 = Very poor     2 = Not good     3 = Fair     4 = Good     5 = Excellent

Back Sleepers

 Back sleepers require proper support for their lumbar region in order to keep the spine aligned. Spine alignment is important for promoting a healthy posture and relieving back pain. That’s why the GhostBed Flex is a smart choice for back sleepers; the durable coils offer superior spine alignment, promoting a straight back all night long. Back sleepers who are lightweight or plus-sized will appreciate the pressure relief from the GhostBed, but some average-weight back sleepers might feel the need for a bit more support. For the most supportive options, see the best mattress for back sleepers.

Stomach Sleepers

 If you are a strict stomach sleeper, it’s critical you consider the firmness level of your mattress. A softer bed will run the risk of hip sinkage, causing your spine to curve inwards. The GhostBed Flex uses a nice blend of foam and coils to smoothly contour to your curves, and the bed’s medium-firmness provides ok support to keep your hips elevated. Some stomach sleepers, particularly average-weight and heavyweight sleepers, may need a firmer bed to prevent their hips from sinking. Lightweight sleepers might find enough support in the GhostBed flex to keep the hips elevated, but it’s no guarantee. 

Side Sleepers

The GhostBed Flex has many qualities side sleepers need for a rejuvenating night’s rest. A soft foam layer contours to lightweight and average-weight sleepers, providing pressure relief for areas of tension and helping to distribute weight evenly, keeping weight off of your hips and shoulders. However, because the bed falls somewhere in the middle of the firmness scale, lightweight side sleepers may prefer a more plush bed for greater pressure relief. For more options, see our best mattresses for side sleepers guide.

Combination Sleepers

Most lightweight, average-weight and plus-size combination sleepers would really enjoy this GhostBed mattress thanks to its quick responsiveness and ability to minimize motion transfer. The responsive innerspring coil layer combined with the memory foam layers works to isolate motion and move with your body as you shift throughout the night. Couples and co-sleepers would rarely feel their partner’s movements on this mattress. As long as you’re not a lightweight sleeper who spends a lot of time on your side or a plus-size combination stomach sleeper, the bed should work well. If you change positions frequently and need a responsive mattress, check out the best mattress for combination sleepers.

How Does It Feel?

Responsiveness, Bounce & Ease of Movement

If you’re a combination sleeper who likes to move around in your sleep, you’re going to want a bed that’s responsive to movement and allows you to feel free to move, rather than bogged down in layers of plushness. The individually-wrapped coils of the GhostBed Flex, as well as the latex layer, make the bed feel responsive. It won’t feel like a struggle to get up out of bed in the morning or even change positions. If you are looking to sink further into the layers or more contouring, check out the best memory foam mattress.

How Firm Is the GhostBed Flex Mattress?

Because it has coils in the support layer, the GhostBed Flex will sleep slightly firmer than its Luxe edition, which is considered softer than medium firm. Do the math and it should be considered medium firm: around a 6.5 on our firmness scale. 

This mattress is designed to accommodate sleepers “of all shapes and sizes” but lighter and heavier customers by body weight will exert less and more pressure on the mattress, respectively. The GhostBed Flex may feel and sleep differently for anyone who hits those extremes.

Does It Sleep Hot? 

GhostBed Flex utilizes most of the same cooling features that the Luxe features use—cooling fibers in the fabric, quilting of the cover, infusing gel that will absorb and dissipate heat into the support layers. In addition to that, coil mattresses always have good airflow because of the space between the coils themselves. Heat doesn’t get trapped there. See the best mattress for hot sleepers for other mattresses that feature cooling technologies. 

Is It Good for Couples? 

Couples or people who sleep with their children or pets, should pay close attention to how well a mattress stops motion from traveling from one side of the bed, where you are sleeping, to the other side where a partner might be shifting around.

Foam mattresses usually do an amazing job of this; innerspring coil mattresses less so. The GhostBed Flex is a hybrid so both factors are at play. However, the coils in the Flex are individually wrapped; that reduces motion transfer.

How’s the Edge Support? 

Most mattresses with a coil layer will do a solid job holding up weight around the edges of the unit. This is important if you sleep with a partner and need to sleep on the entire mattress surface.

The core of the GhostBed Flex features both the regular base of coils and an additional two rows of coils around the edge to reinforce the edges of the mattress and allow couples to use the whole thing. You’ll also be able to sit on the edge without feeling like you’re gonna slip off. When considering edge support, it is also important to pick the right size of mattress. See the best queen size mattress and best king size mattress depending on which size mattress works for you.

Construction: What’s Under the Surface

The GhostBed Flex is a 13-inch thick, memory-foam-and-coil hybrid mattress made of seven layers. Again, the selling point here is that the layers combine the cooling aspects of the Luxe version, the comfort of memory foam, and a durable, responsive innerspring coil base layer to accommodate many different shapes, sizes and types of sleepers.

Layer 1: Quilted CoverThe cover is quilted, which enhances airflow to let heat dissipate. One inch of cooling fibers is woven directly into the cover to increase the amount of air flowing through. 

Layer 2: Gel Memory Foam: A layer of 1 inch of gel-infused memory foam lies directly under the cover. The gel transfers heat away from the body, and the foam acts like any memory foam in that it will cover around your body and help keep your spine aligned. That’s why GhostBed added another inch of gel-infused memory foam just below it. 

Layer 3: Ghost Bounce Layer: Next comes the transition foam layer of the mattress. It measures 1 inch and is slightly denser, but still conforms to the body. It’s called a transition layer because it will cushion your body from sinking straight into the coils. The brand advertises this layer as a material that mimics both memory foam and latex; it eases the transition from the comfort to the support layer.

Layer 4: Individually-wrapped Coils: The next layer is 8 1/2 inches of reinforced and individually wrapped coils. The coils make this mattress extremely durable. It will hold up sleepers of all weights and add to the mattress’ durability, giving you the 7-to-10 years of use everyone should expect from a quality mattress. This layer includes an additional 1 1/12-inch of specially reinforced coils around the edges of the unit to enhance edge support.

Layer 5: High-density Support Layer: The final layer is a final inch of solid medium density foam beneath the coils, added for durability.

How Do the Policies Measure Up? 


The GhostBed Flex comes with a 101-night trial period. That amount of time sounds amazing. And while it is longer than industry standard, it’s a longer term than industry standard by only 24 hours. Also, your trial period will start on the day the mattress is shipped (not on arrival day).

After 30 days and before 101 days, you can initiate a return with GhostBed if the mattress just doesn’t work for you. GhostBed will look to fix what is wrong or give you a refund, depending on the situation. GhostBed will not take the mattress back. It does suggest if you do want a refund, to donate it to a charity of your choice.


The GhostBed Flex mattress is backed by a 25-year warranty, but it’s limited. Remember that mattresses should be replaced every 7 to 10 years regardless of the warranty term.

If you engage the terms of the warranty, GhostBed will decide whether the mattress can be repaired or should be replaced minus shipping and handling costs for getting the unit back to them.

Also, for the first 10 years, the limited warranty covers sags or body impressions greater than 1 inch or any material flaw that causes the mattress to split. If you don’t use the mattress on a solid base, boxspring or adjustable base, the warranty is void. The warranty doesn’t cover normal wear and tear or abuse by the owner.

From years 11 through 25, GhostBed may repair the mattress minus the shipping costs, or replace it at a prorated price ranging from 50 percent of the original purchase price in year 11 to 55 percent of the original price in years 21-25.

Delivery & Setup

GhostBed says it will have shipped your mattress to you within 24 hours of you ordering it. Since all of the mattresses are manufactured stateside, it should arrive within 3-5 business days. GhostBed ships via FedEx for free, unless you live in Alaska and Hawaii. To ship to either state costs $600. Sales to residents in either place are also final.

The GhostBed Flex is delivered vacuum-compressed and rolled in a box. You will likely need someone to help you handle it. 

It’s fascinating to think that someone can ship a mattress in a box to your door.  But know that, once freed from its plastic wrapping, the GhostBed Flex will take somewhere from several hours to several days to re-inflate to its full thickness. That time depends on factors like the temperature and humidity.

Customer Service

The customer service folks behind GhostBed will field calls or chat online with you during regular business hours 7 days per week. You can email them as well.

GhostBed will work with consumers to find the right solution if the Flex hybrid doesn’t quite meet your expectations. They reserve the right to offer an alternative, repair any accepted defects listed in the warranty, replace the mattress or refund the price if you “return” the mattress.

We say “return” because you don’t give the mattress back. You will be responsible for getting rid of the GhostBed Flex mattress they sent you. GhostBed won’t reclaim the actual mattress, but refund your payment if you ask for a refund after 30 days and before 101 days.

Comparing the GhostBed Flex

GhostBed Flex vs Nectar


The Nectar is an affordable quality mattress with an excellent trial period. It suits all types of sleepers, couples and people who love sleeping on memory foam.

Better suited for side sleepers and lighter back sleepers, the Nectar Mattress uses gel infused memory foam to contour around the body. It will lack the bounce and edge support of a hybrid mattress like the GhostBed Flex and is slightly softer.

GhostBed Flex vs GhostBed Luxe

GhostBed Luxe

Considered one of the best cooling memory foam mattresses on the market, the GhostBed Luxe is a great option for sleepers who love the feel of memory foam but tend to sleep hot.

If you’re looking for ultimate cooling in a GhostBed model, the GhostBed Luxe is here to help. It includes phase-changing material in the construction to adapt to the body heat of the sleeper, but it still has an all-foam construction instead of a hybrid construction with coils. Though it’s a bit more expensive than the GhostBed original, we think it’s a great fit for those with cooling as a main priority.

Read our full GhostBed Luxe Mattress Review to find out more. 

GhostBed Flex vs Leesa


The Leesa mattress adapts to all sleep positions and most body types. With its cooling foam and additional layers that both hug and support you, it's no wonder customers love sleeping on their Leesa.

The Leesa is another all-foam mattress that targets side sleepers with plush comfort, compare to the firmer GhostBed Flex. The Leesa can work for some heavier sleepers and is at a more affordable price point. While the GhostBed Flex may provide a better structure for cooling, the Leesa’s memory foam layers will provide pressure relief and pain relief for struggling sleepers.

What’s the Bottom Line

GhostBed Flex was designed to suit almost every kind of sleeper, but there really is no single mattress that can accommodate every type, size, and shape of the sleeper. It may be a good fit for most, and that is what the GhostBed Flex is really trying to achieve.

The Flex combines most of the cooling features of the GhostBed Luxe and the contouring or memory foam with a coil layer that should give the bed both durability and bounce. The bounce and responsiveness is important because, unlike some all-foam mattresses that you sink into, it will help you get out of bed. It’s great for those who sleep on their back and stomach, but it might not offer enough support and comfort for side sleepers. 

Hybrid mattresses like the Flex are usually good for heavier sleepers because heavier bodies will put more pressure on the mattress and engage all of the support layers. It should work well for combination sleepers, too, because of the amount of gel-memory foam that is used in the top layers. At any rate, the 101-night sleep trial makes it easy to try the mattress out and see if it’s right for you.


Will I experience any off-gassing smells with the GhostBed Flex? 

There is a faint smell when you first unbox your new GhostBed Flex mattress, but this will dissipate quickly and is harmless. All of the materials used in the GhostBed are CertiPUR-US certified meaning they contain no harmful chemicals or heavy metals.

How much weight can the GhostBed Flex support?

The GhostBed Flex can support up to 750 lbs as long as its placed on a strong foundation like a boxspring or adjustable base.

Is there a break-in period for the GhostBed Flex?

When you first unbox your GhostBed Flex, it may take a few hours for the mattress to fully expand, breathe, and adjust to your room’s temperature, but you can still sleep on it almost immediately. A new mattress is a big change for your body so keep in mind it may take a night or two to adjust.
