Most sleepers find it easy to move around on the Serta Perfect Sleeper mattress in a box.

Many find that all-foam mattresses contours closely and can restrict movement if the comfort layers slowly return to their original shape. Traveling from one end of the mattress to the other is a bit more complicated.

Pocketed springs of extra bounce, making it easier to change positions or move around as needed. Hybrid mattresses of the Serta Perfect Sleeper mattress in a box tend to balance ease of movement with motion isolation due to the blending of coils and foam.

The memory foam isolates movement and pocketed coils provide additional bounce to prevent feeling restricted by the comfort layers.

Comfort, Back Support, Pressure Relief


The hybrid creation of the Serta Perfect Sleeper mattress in a box helps relieve pressure points while promoting spinal alignment. The memory foam comfort layer hugs the body and contours its shape to relax pressure points; the wrapped coils provide robust support.

The Plush model scores exceptionally well for pressure relaxation. The comfort layer of soft foam allows sleepers to sink deep into the mattress. It pads areas like the shoulders and hips, where pressure build-up is more.

The Medium and Medium Firm variations also provide pressure relief for sleepers of the heavyweight category, mainly those who weigh above 130 pounds.

Cooling & Temperature Control


Hybrid mattresses regulate temperature exceptionally well since the wrapped coils circulate air and help remove heat. The comfort layers ab in the mattress can affect temperature neutrality.

An entire foam mattress is more likely to retain heat; using a thin layer of foam above pocketed coils allows better air circulation.

As the Medium and Medium Firm models do not contour closely, air can circulate through the body to help prevent heat build-up. The Plush model is softer, hugs the body closely, and may retain more heat than the firmer models. Still, this only plush model consisting of 825 individually wrapped coils allows air circulation well.

The use of HexCloud™ Gel Memory Foam and Cool Twist® Gel Memory Foam improves the heat dissipation capacity of the mattress and lets Sleeper sleep cool throughout the night.

Motion Isolation and Sharing a Bed


A coiled mattress engrosses movements like all foam, so the Sleeper on one side of the mattress is less likely to be disturbed by motions on the other. This parameter makes Serta mattresses, in general, a good choice for couples. The foams offer outstanding comfort. Depending on personal preference, any bed from the Perfect Sleeper line-up can be selected, but the hybrid versions with 825 individually wrapped coils provide maximum motion isolations.

Edge Support


The Serta Perfect Sleeper Mattress offers some edge-to-edge support. Edge support gives a measure of how sturdy the sides of your mattress are. If a mattress comes with good edge support, it won’t collapse under your weight when you roll to the side of the bed. A good mattress for couples will have strong edge support so that sleepers enjoy the entire surface area of their bed without feeling unstable. People don’t have the sensation of rolling off the border; while sleeping, they want a more excellent surface. Usually, wrapped coils in the hybrid models come with good edge support.

Recommendation based on sleeping style

Q1. How would you describe the Serta Perfect Sleeper mattress based on individual sleeping style?

  • Side Sleepers: more curves are available on our side. Shoulders. Hips. Knees. These areas create tension and pressure. Ideally, a softer mattress cradles the hips and shoulders to prevent stress and injury.
    The Serta Perfect Sleeper Mattress is exceptionally well for side sleepers irrespective of body type. The blend of pocketed coils and memory foam gives these sleepers excellent pressure relief and spinal alignment.
    The Renewed Relief™12model has a more comfortable layer of memory foam, which contours to the body’s shape and helps prevent pressure points. The wrapped coil core delivers adequate support to help keep the spine positioned throughout the night.
    This Plush model is highly rated by side sleepers who weigh below 230 pounds, while those who weigh above 230 pounds prefer the medium option.
  • Back Sleepers: Sleeping on the back is the best for spine health. Sleepers want a mattress that keeps weight off the joints and pressure points and cradles your spine optimally to maintain healthy alignment.
    The Medium firm variety of the Serta Perfect Sleeper Mattress is suitable for back sleepers. The Plush and Medium models are ideal for sleepers who weigh below 130 pounds. For the heavyweight group, the Medium Firm version also works.
    Regarding spinal alignment, support for the shoulders and lumbar region are among the most critical point for back sleepers to check. The Serta Perfect Sleeper mattress in a box combines memory foam and wrapped coils to provide the contouring and backing needed for sleeping on the back.
  • Stomach Sleepers-Stomach sleepers are at the most significant risk of spinal problems as there is a great deal of pressure on the thoracic and lumbar spine.
    Although the Serta Perfect Sleeper Mattress scores well for stomach sleepers, there are a few additional considerations to remember.
    The most common cause of pain for stomach sleepers is spinal misalignment from sinking into the mattress. The more the midsection presses into a mattress, the more likely Sleeper will experience pressure on their lower back.
    Stomach sleepers prefer a firmer mattress that gives more support for the mid-portion, which helps maintain the spine straight and prevents back pain. As a result, most stomach sleepers prefer the Serta Perfect Sleeper Nested night and Tranquil wave Mattress in Medium or Medium Firm. The comfort layer of memory foam cushions the upper body while preventing sleepers from sinking in too deeply.
