Serta Perfect Sleeper Mattress Review: Test Lab Ratings

The extent to which the Serta Perfect Sleeper X isolates motion will depend on the firmness level. The Plush model stands out with strong motion isolation, while the Medium and Firm models are more likely to transfer some movement.

This is a hybrid mattress that uses both memory foam and pocketed coils in its construction. While memory foam is known for its motion-isolating properties, the coils add bounce and may transfer movements like changing positions or getting in and out of bed.

The Plush model uses soft memory foam that is slower to return to its original shape when pressure is removed, and it absorbs and isolates movement well as a result. The Medium model performs on par with most hybrid models. The Firm model has a thinner memory foam comfort layer, which makes motion transfer from the coils more noticeable. The coils are pocketed to help minimize this effect.

The hybrid construction of the Perfect Sleeper X helps relieve pressure points while promoting spinal alignment.

While the memory foam comfort layer cradles your body and contours to its shape to relieve pressure points, the pocketed coils provide robust support.

The Plush model rates exceptionally well for pressure relief. The softer foam comfort layer allows sleepers to sink into the mattress a bit more. It cushions areas like the shoulders and hips, where pressure is most likely to build.

The Medium and Firm models also provide pressure relief for sleepers, particularly those who weigh more than 130 pounds.

Hybrid mattresses tend to regulate temperature exceptionally well, as the pocketed coils circulate air and help dissipate heat. The comfort layers used in the mattress can affect temperature regulation.

While a mattress made entirely with foam is more likely to retain heat, using a thin layer of foam above pocketed coils allows for better airflow.

Since the Medium and Firm models do not contour closely, air can circulate around the body to help prevent the buildup of heat. The Plush version is softer and more conforming, and it may retain more heat than the firmer models.

If you find yourself slipping off the edge of your mattress while sitting along the side, it is likely the result of poor edge support. The Serta Perfect Sleeper X offers edge support that greatly decreases or eliminates the feeling of rolling off the edge of the bed.

Serta uses a foam rail around the perimeter of the mattress to ensure better support. This design element is effective in each firmness level.

That said, the edges feel more supportive in the Medium and Firm models. Sleepers are likely to notice that the soft foam layer in the Plush model compresses slightly as they near the edge of the bed.

Most sleepers should find it easy to move around on the Perfect Sleeper X.

Many people find that an all-foam mattress contours closely, and can restrict movement if the comfort layers are slow to return to their original shape. This can make movement from one side to the other a bit more difficult.

Pocketed coils provide extra bounce, making it easier to change positions or move around as needed. Hybrid mattresses like the Serta Perfect Sleeper X tend to balance ease of movement with motion isolation, due to the combination of coils and foam.

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