Meet Our Testing Team
- Individuals who weigh at least 130 pounds. The GhostBed Flex has a medium firm feel that provides the best pressure relief to average weight and heavyweight sleepers.
- Couples. Sturdy edges increase the usable sleep surface while pocketed coils and memory foam reduce motion transfer, reducing nighttime disruptions when sharing the bed with a partner.
- Those who sleep hot. Comfort layers with cooling features and abundant airflow through the pocketed coils help the bed keep a neutral temperature through the night.
Not Recommended for...
- Lightweight individuals. Individuals who weigh less than 130 pounds tend to be more comfortable on a mattress with softer comfort layers, such as an all-foam mattress.
- Those who prefer close-conforming beds. The memory foam provides some contouring, but the GhostBed Flex has thinner comfort layers and does not offer the full-body “hug” of an all-foam mattress, so some individuals may find it too firm.
We’ve prepared a detailed review of the GhostBed Flex, but you can also watch the video below to see how our sleep team rated the mattress.

In addition to physical testing, we surveyed our sleep expert team and analyzed reviews from verified mattress owners and customers. Our findings are listed in the table below.
|Sleep Position||Less than 130 LBS||130 LBS - 230 LBS||Greater than 230 LBS|
How Is the GhostBed Flex Mattress Constructed?
Made of a sleek viscose-polyester blend, the cover of the GhostBed Flex is engineered to feel cool to the touch. It’s quilted with an inch of fiber padding designed to promote airflow, plus another inch of plush gel memory foam that provides contouring pressure relief.
The main comfort layer consists of an additional inch of memory foam for added pressure relief. Like the layer above it, this memory foam is infused with gel beads designed to draw heat away from the sleeper’s body.
Between the comfort layers and the coil support base is an inch of plush polyfoam that provides additional contouring and acts as a transitional layer to prevent sleepers from hitting the firmer support layers.
In the support core are 8.5 inches of individually wrapped coils, with two rows of higher-gauge coils on the edges to provide extra reinforcement. The coil count in the queen mattress is 682, which is a little on the low side and may shorten the lifespan of the mattress. An inch of high-density polyfoam provides a base for the coils.
The GhostBed Flex is 13 inches tall. This is taller than the average mattress but on par with other hybrid mattresses, as they need room for the comfort layers above the pocketed coils. With 4 inches of comfort and transitional layers, the GhostBed Flex should provide a good enough cradle to relieve most pressure points, especially in average weight and heavyweight sleepers.
Customers should keep in mind that taller mattresses require fitted sheets with a deeper pocket. Moreover, our team found the cover quite sleek, which sometimes caused the sheets to slip off.

What Are the Firmness and Feel Like?
GhostBed describes the mattress as between a 5.5 and a 6.5 out of 10 on the firmness scale. Our team agreed, rating the bed as a 6 out of 10, or medium firm. This places the mattress in the “sweet spot” between 5 and 7 that appeals to the vast majority of sleepers.
The memory foam layers allow the sleeper to sink into the mattress, conforming closely and preventing pressure build-up. In the support core, the springs provide a responsive base that keeps sleepers aloft and helps promote spinal alignment, leading to a balanced feel between sleeping “in” and “on” the mattress.
Overall, this balanced feel is most suitable for individuals who weigh at least 130 pounds, although pressure points were minimal in our lightweight sleep testers as well.
Next, let’s take a closer look at our performance ratings for the GhostBed Mattress. These ratings are based on findings from our internal and external testing teams, as well as verified owner and customer experiences with the mattress.
Since the GhostBed Flex was only released in 2015, we’re primarily basing our assessment of its durability on its materials and construction. Judging by this, we expect the mattress to have a comparatively long lifespan of about seven years
Hybrid mattresses vary widely in durability as they have so many different components. The GhostBed Flex has less soft foams than other mattresses, which may prolong its lifespan before it starts to develop permanent body impressions. We recommend rotating the mattress from head-to-foot every 3 months to prevent these indentations from forming so quickly.
The Ghost Bed Flex’s coil count is on the low side for a hybrid mattress. Because of this, the coils may start to break down earlier than some hybrids. On the other hand, pocketed coils still last longer than all-foam support cores, and the high-density polyfoam base also helps ensure a longer lifespan.
To test motion isolation in the GhostBed Flex, we asked our heavyweight sleep tester to change positions and get in and out of bed, while another sleeper felt for movement on the other side of the bed. The team found little to no motion transfer, especially when the two individuals were at least 6 to 8 inches away from each other.
The inherent bounce of any coil mattresses naturally transfers some motion across the sleep surface. However, the pocketed coils in the GhostBed Flex absorb much more motion compared with the interconnected coils in a traditional innerspring mattress. Memory foam in the comfort layers and high-density polyfoam in the base also help to isolate motion, making this mattress a workable option for couples.
As with any foam mattress, our team noticed some odors when the mattress first arrived, but these were not bothersome and did not linger. The GhostBed Flex has less foam layers than other hybrid mattresses, and airflow through the coils helps the odors dissipate. All foams in the GhostBed Flex are CertiPUR-US certified and low in volatile organic compound (VOC) emissions.
Our sleep team used a pressure mapping tool to identify pressure points throughout the testers’s bodies when laying on the GhostBed Flex. When lying on the sensory pad, sleepers across all weight categories found ample pressure relief in the GhostBed Flex mattress.
In-house and out-of-house sleep testers agreed that the layers of gel memory foam and the polyfoam transitional layer allow just the right amount of sink to alleviate pressure points that commonly form in heavier body parts, such as the hips and shoulders. Even lightweight sleepers, who often find mattresses too firm, felt sufficiently cradled in the GhostBed Flex.
Our sleep team rated the GhostBed Flex as fairly temperature neutral. As a hybrid mattress, the GhostBed Flex allows strong airflow through the coils which helps it sleep significantly cooler than the average all-foam mattress.
The fiber padding in the cover is intended to promote airflow, and the memory foam is infused with gel beads which are meant to help it sleep cooler. However, people who tend to sleep hot may find the mattress still traps some heat in the comfort layers.
Hybrid mattresses tend to have better edge support than most other types, and all of our sleep testers were able to sleep near the edge and even sit on the edge of the bed without feeling like they were falling off. This is mainly due to the higher-gauge coils used around the edges.
While it may fall short of the edge support provided by a traditional innerspring mattress, the relatively thin comfort layers allow sleepers to sink just several inches into the mattress before being bolstered by the pocketed coil support layer.
Unsurprisingly, we found that the GhostBed Flex mattress produced some subtle squeaks and creaks when our sleep testers switched positions or got in and out of bed. This is typical of hybrid mattresses and is due to the coils in the support core, which have a tendency to produce more noise as time goes on.
The comfort layers help muffle some of the noise, and pocketed coils make less noise than traditional innerspring mattresses. However, sensitive sleepers may prefer an all-foam or latex mattress, both of which are virtually silent.
According to our sleep team, the GhostBed Flex offers the perfect blend of attributes for sex. A moderate amount of bounce from the pocketed coils facilitates motion, while the memory foam comfort layers provide just the right amount of traction. Strong edges allow couples to use the full surface of the bed.
The only slight disadvantage is the somewhat noisy coil layer, which may inhibit couples who wish to be discreet.
Because sleeper ratings can vary depending on body type and position preference, ourk sleep team comprises a variety of different sleeper profiles. While the mattress was ranked highly by all of our sleep testers, the sleeper rating section will discuss how the feel of the GhostBed Flex changed according to the experiences of our different testers.
Lightweight Sleepers – Less than 130 lbs.
Across the board, lightweight sleepers on our testing team found a good level of pressure relief and support in the GhostBed Flex. The comfort layers of the mattress offer close conforming for heavier body areas like hips and shoulders, while the quilted fiber padding and gel memory foam add some initial plushness to prevent the bed from feeling too firm.
Back sleepers tend to prefer mattresses that offer a balanced feel, and the GhostBed Flex kept our back sleepers aloft while cradling the body to reduce pressure build-up. Lightweight stomach sleepers on our team felt properly supported under the hips, keeping the spine properly aligned and leading to a comfortable night’s sleep. Side sleepers sank a little further into the mattress, but received sufficient pressure relief so as not to experience undue pain in the hips or shoulders.
Average Weight Sleepers – 130 to 230 lbs.
Average weight sleep testers gave the GhostBed Flex the highest ratings, with back sleepers in particular finding that the bed evenly distributed their body weight. The pocketed coil support core supports spinal alignment no matter the sleep position, while the comfort layers contour to the body and prevent pressure points.
Typical of a hybrid mattress, the GhostBed Flex combines pressure relief and support for a balanced feel that is best suited to average weight sleepers. Side sleepers on our team experienced minimal pressure in the hips and shoulders thanks to the comfort layers, while the pocketed coil layer provided adequate support for the hips in stomach sleepers.
Heavyweight Sleepers – More than 230 lbs.
More than the other groups, our heavyweight sleepers described the feeling of sleeping on the GhostBed Flex as sleeping “in,” not “on,” the mattress. Individuals who weigh more than 230 pounds will sink just far enough into the mattress to experience the pressure-relieving cradle. Meanwhile, the combination of pocketed coils and high-density polyfoam in the base layers form a stable support core that promote proper spinal alignment in most heavyweight sleepers.
Back sleepers and stomach sleepers on our testing team were properly supported in the hips and lumbar area. Side sleepers found that their hips and shoulders were cushioned enough to relieve pressure points, while still keeping the spine aligned.

How Does the GhostBed Flex Mattress Compare to Other Beds?
There are many hybrid mattresses with similar designs to the GhostBed Flex. To help you in your mattress search, we’ve outlined the key differences between some of its leading competitors, as well as the other GhostBed models.
GhostBed Flex vs. The GhostBed
The flagship GhostBed is an all-foam mattress with aerated latex, gel memory foam, and a high-density polyfoam core. The mattress is 11 inches tall and ranks a 6 out of 10 on the firmness scale, or medium firm.
As an all-foam mattress, the GhostBed lacks the reinforced edges provided by the coils in the GhostBed Flex. This can cause sagging along the perimeter and is not ideal for people who sleep near the edge of the bed. On the other hand, the GhostBed is completely silent when bearing weight, which is better for sensitive sleepers.
Although usually a key strength of all-foam mattresses, both these models do a good job of providing pressure relief and isolating motion transfer. However, heavyweight sleepers are better suited to the GhostBed Flex, which provides extra support thanks to the coil layer. The coils in the GhostBed Flex also allow airflow and provide more responsiveness, meaning this mattress will be better for sex, combination sleepers, and those who tend to sleep hot.
The GhostBed is quite a lot cheaper than the GhostBed Flex, but the GhostBed Flex offers advantages that may be worth the price for some sleepers.
GhostBed Flex vs. GhostBed Luxe
The GhostBed Luxe is an all-foam mattress that incorporates gel memory foam and phase-change materials into the cover designed to keep sleepers cool. Gel memory foam and polyfoam comfort layers rest atop a high-density polyfoam base. In total, the mattress is 13 inches thick with a medium firmness level, or 5 out of 10.
The plusher GhostBed Luxe provides extra pressure relief for lightweight sleepers, but may cause some sagging in the hips for heavyweight individuals who sleep on their back or stomach. Both mattresses perform similarly on motion isolation and pressure relief. Despite being an all-foam mattress, the GhostBed Luxe also holds its own in responsiveness and edge support, and the cooling materials help give the mattress excellent temperature neutrality.
The GhostBed Luxe is priced on the high side for an all-foam mattress, giving it a similar price-point to the GhostBed Flex.
GhostBed Flex vs. Casper Hybrid
One of the latest mattresses released by Casper is the Casper Hybrid, a hybrid mattress with memory foam and polyfoam comfort layers and a support core constructed with individually wrapped coils. The Casper Hybrid is considered medium, or 5.5 out of 10 on the firmness scale, and measures 12 inches tall.
With its “medium” feel, the Casper Hybrid supplies better pressure relief and is best suited to lightweight individuals. The pressure relief comes at the expense of responsiveness, which is better in the GhostBed Flex. Heavyweight sleepers require a firmer surface and a more robust support core, and should therefore opt for the GhostBed Flex.
The Casper Hybrid has surprisingly weak edges for a hybrid mattress, leading to potential feelings of instability around the perimeter. This may be a problem for people who share the bed, as it reduces the usable sleep surface. On the other hand, the Casper Hybrid doesn’t produce as much noise as the GhostBed Flex, causing less disruption to a sleep partner.
The Casper Hybrid and GhostBed Flex are priced in the same range but the Casper Hybrid is slightly more affordable, which may be the deciding factor for some shoppers.
GhostBed Flex vs. WinkBed
With four firmness options and thick layers of polyfoam and micro-coils over a zoned support core of pocketed coils, the WinkBed aims to appeal to a wide range of sleeper profiles. The mattress is 14.5 inches tall and its firmness levels are Soft (4.5), Luxury Firm (6.5), Firmer (7.5), and Plus (8). The Plus version replaces the micro-coils with a layer of latex, and all four models have a cotton lumbar pad for additional lower back support.
The WinkBed Plus provides above-average support for heavyweight sleepers, and between them, the other WinkBed models rank highly across sleeper profiles as well. A polyfoam casing around the perimeter of the WinkBed adds extra reinforcement to the edges.
For its part, the GhostBed ranks better on motion isolation. Both mattresses succeed at preventing heat build-up and alleviating pressure points. The WinkBed and GhostBed Flex have comparable price-points, while the WinkBed Plus is a little more costly.
GhostBed Flex vs. Brentwood Home Oceano
The Brentwood Home Oceano incorporates organic wool, gel memory foam, pocketed coils, and polyfoam in the comfort layers, with a pocketed coil support core. In terms of firmness the mattress is similar to the GhostBed Flex at 6 out of 10, or medium firm. The Oceano has a 14.5 inch profile.
A thin layer of wool underneath the cover improves breathability in the Brentwood Home Oceano, giving it temperature regulation abilities that are on par with the GhostBed Flex. Like the GhostBed Flex, the Brentwood Home Oceano has lower-gauge coils along the perimeter to reinforce the edges.
In conjunction with the gel memory foam, the microcoils in the Brentwood Home Oceano provide a pressure-relieving cradle which lightweight individuals find very comfortable. Nevertheless, this mattress allows too much sagging in individuals over 230 pounds, for whom the GhostBed Flex is a better choice.
Although the mattresses are sold at almost exactly the same price, we expect the Brentwood Home Oceano to have a slightly longer lifespan, which would make it a better investment, all other things being equal.
GhostBed Flex vs. Helix Midnight
The Helix Midnight is a budget-friendly hybrid mattress measuring 12 inches tall. The mattress combines gel memory foam, a transitional layer of polyfoam, and a pocketed coil support core resting on a high-density polyfoam base. The mattress has a medium firmness level, or 5.5 out of 10. Like the GhostBed Flex, the Helix Midnight offers a balance of support and pressure relief.
Because of the extra inch in its comfort layer section, the GhostBed Flex performs better on motion isolation, pressure relief, and temperature neutrality. The GhostBed Flex also provides more support for individuals over 130 pounds, while the Helix Midnight may be slightly more comfortable for lightweight individuals who sleep on their back.
The major advantage of the Helix Midnight is its competitive pricing. The Helix Midnight is a good entry-level option for shoppers who want a hybrid mattress but can’t afford the prices they usually retail at.
