The GhostBed Flex is an affordably-priced hybrid model constructed of six layers, including a quilted cover, two layers of memory foam, two layers of polyfoam, and a layer of pocketed coils.

GhostBed Flex Mattress Review Breakdown

The GhostBed Flex uses a hybrid construction with six distinct layers. A quilted cover tops the mattress. This fabric is crafted to feel cool to the touch, while a 1-inch layer of cooling fiber quilted into the cover further cools the surface of the bed. Next, there are two 1-inch layers of memory foam that hug to the body to relieve pressure buildup while supporting the sleeper’s natural spinal alignment. This memory foam is infused with gel to transfer heat away from the sleeper’s body.

A 1-inch polyfoam transition layer combines the responsiveness of latex and the conforming of memory foam. This layer serves as a barrier to prevent the sleeper from sinking in against the coil core.

The support core uses 8.5 inches of pocketed coils. Since each coil is individually encased, minimal motion transfers between coils. Substantial airflow through the coil system helps keep the mattress cool. This layer also uses two rows of reinforced coils around the perimeter of the bed to give the edge a sturdier feel. A 1-inch layer of polyfoam acts as a base for the coil system.

With its rating of 6 on the 10-point firmness scale, the GhostBed Flex has a medium firm feel, which is one of the most popular firmness settings. Regardless of their weight or sleep position, most individuals are likely to find a medium firm feel acceptable.

The GhostBed Flex is 13 inches thick, making it a high-profile model. It may require deeper-pocketed sheets to accommodate this thickness.

The GhostBed Flex contains six main layers. A quilted cover with cooling fiber fill is the top layer. Next, there are two layers of gel-infused memory foam. A polyfoam transition layer separates the memory foam layers from a pocketed coil core. Finally, a layer of polyfoam acts as the base of the bed.

Mattress Performance

Motion Isolation

The GhostBed Flex’s comfort system absorbs a moderate amount of motion. A quilted cover and two comfort layers of memory foam help reduce the transfer of vibrations across the surface of the bed.

Since the coil core gives the GhostBed Flex bounce, it could also lead to some motion transfer. However, this is mitigated somewhat by the pocketing of the coils. Most hybrid models have similar motion isolation to the GhostBed Flex.

Motion isolation tends to be particularly important for sleepers who awaken when their partner moves during the night.

Motion Isolation
Pressure Relief

A soft quilted cover, two layers of memory foam, and a polyfoam transition layer give the GhostBed Flex significant pressure relief compared to the average hybrid model. The quilted cover provides cushioning, while the two memory foam comfort layers adjust to the shape of the sleeper to cradle them and relieve their pressure points. The polyfoam transition layer contours more deeply while limiting sinkage.

Since weight influences how deeply a sleeper sinks into a mattress, it also plays a role in how much pressure relief they experience. Sleepers who weigh between 130 and 230 pounds may experience the best balance of pressure relief and support. Individuals who weigh under 130 pounds won’t sink in as deeply, so they may have more pronounced pressure points.

Pressure Relief
Temperature Control

Hybrid mattresses tend to have stronger temperature regulation thanks to their breathable cores, and the GhostBed Flex is no exception.

The GhostBed Flex’s temperature-regulating features start in the cover, which is quilted with cooling fiber to be cool-to-the-touch while allowing ample airflow. Both layers of memory foam used in the comfort system are infused with gel, which helps pull heat away from the sleeper’s body. Airflow through the coil core further allows heat to dissipate.

People who feel hot during the night may appreciate the GhostBed Flex’s degree of temperature control.

Temperature Control
Edge Support

A sturdy edge can allow sleepers to use more of the surface of a mattress. When an edge compresses too much, sleepers tend to gravitate towards the center of the bed to avoid the feeling of instability near the perimeter. Those who sit on the edge of the bed may also find it challenging on a mattress without adequate edge support.

Like many hybrid models, the GhostBed Flex has a reinforced edge that makes it easier to sit or sleep close to the perimeter of the bed. Two rows of reinforced coils around the perimeter of the GhostBed Flex limit edge sinkage and give it a more secure feel.

Edge Support
Ease of Movement

Hybrid models tend to be relatively easy to move on due to their coil cores, and the same is true of the GhostBed Flex. This is beneficial for sleepers who tend to change positions during the night.

Memory foam often makes a mattress more challenging to move on due to its slower response to changes in pressure and its close conforming. However, the GhostBed Flex uses two relatively thin layers of memory foam, so sleepers shouldn’t feel “trapped in the bed.” The polyfoam transition layer is engineered to provide the responsive feel of latex, adding to the mattress’s ease of movement.


The GhostBed Flex combines bounce and contouring, both of which can be beneficial for sex.

Its responsive polyfoam transition layer and coil core give the GhostBed Flex the springiness that many couples prefer for sex. Two layers of memory foam in the comfort system also contour enough to give some traction.


Because foam often has lingering odors left over from the manufacturing process, most mattresses that contain synthetic foam and ship compressed are likely to off-gas at first. These smells are not usually considered harmful, but individuals who find them off-putting can leave the mattress in a well-ventilated room until it airs out. You can generally expect this to take between a few hours and a few days. Since the GhostBed Flex is breathable, we would expect it to air out more quickly than some models.

Sleeping Style and Body Weight

Side Sleepers:
Side sleepers from all weight groups may find the GhostBed Flex comfortable due to its mixture of contouring and support. The quilted cover gives surface-level cushioning, and two layers of memory foam shape to the side sleeper’s curves. A polyfoam transition layer gives deeper contouring while providing support.

Because of its medium firm feel, the GhostBed Flex may be best for side sleepers who weigh between 130 and 230 pounds. People in this weight group are likely to get the best balance of cradling and support, which can help relieve a side sleeper’s pressure points while supporting their spinal alignment.

Side sleepers who weigh less than 130 pounds may find the GhostBed Flex firmer than ideal, which could contribute to more pressure buildup around their hips and shoulders. Those who weigh over 230 pounds may have a harder time keeping their spines aligned since they’ll sink in more than lighter individuals.

Back Sleepers:

Back sleepers generally need a surface that doesn’t sag to support their natural spinal alignment. The GhostBed Flex’s responsive polyfoam transition layer and supportive coil core provide an even plane suitable for back sleeping. Its quilted cover and two layers of memory foam also provide enough cushioning and cradling for added comfort.

Across all weight groups, most back sleepers are likely to receive sufficient support from the GhostBed Flex, though some sleepers over 230 pounds may find the bed’s feel too soft. Those who weigh less than 130 pounds and prefer a plusher sleep surface may find the GhostBed Flex’s medium firm feel slightly firmer than ideal. Back sleepers who weigh more than 130 pounds might experience mild sinkage near their hips, which could impact their spinal alignment.

Stomach Sleepers:

A stomach sleeper’s midsection usually puts the most force on a mattress since it tends to be the heaviest part of the body. This can pull the sleeper’s hips too deeply into the mattress and put a strain on their spine. Because of this, most stomach sleepers need a supportive mattress.

The GhostBed Flex’s supportive transition and coil layers work to prevent sinkage, so most stomach sleepers should get enough support. Many individuals who sleep on their stomachs may also appreciate the cushioning of the quilted cover and two memory foam comfort layers.

With its medium firm feel, the GhostBed Flex may be most suitable for stomach sleepers who weigh less than 230 pounds. Those who weigh more than 230 pounds are likely to experience more midsection sinkage, which may contribute to lumbar strain.
