Being an all-foam offering, you may experience some sinkage while sleeping on the Simmons Memory Foam mattresses. The Firm version may cause lesser sinking. You might sink more on the Plush and Medium versions of this bed.

Comfort, Back Support, Pressure Relief


Based on personal reviews, here’s how the Simmons Memory Foam Mattress performs on the bases of Pressure Relief, Responsiveness, Cooling, Motion Isolation, Edge Support:

The Simmons Memory Foam mattress has three firmness options: Firm, Medium, and Plush. While the Firm variant has a firmness level of 3 out of 10 on the firmness scale (with 0 being the firmest and 10 being the plushest), the Medium version rates around 6, and the Plush variant rates 9. The Simmons Memory Foam mattress has an all-foam built. It offers you a perfect balance of support and comfort. These mattresses allow you to sink in slightly and conform to the pressure areas. The memory foam comfort layers provide excellent contouring, while the base of the bed offers great support.

Cooling & Temperature Control


The Simmons Memory Foam mattress models trap heat due to their all-foam construction. However, the gel infusion in the memory foam layers performs to wick away some heat. But the hot sleepers might prefer a cooler mattress to sleep on.

Motion Isolation and Sharing a Bed


Memory Foam mattresses offer more excellent motion isolation, which is true with the Simmons Memory Foam mattress models. The dense foam layers prevent motion from traveling to other sides of the bed. Thus, you won’t feel when your partner moves. The Medium and Plush models perform better in isolating motion due to the varying densities of the memory foam.

Edge Support


The Simmons Memory Foam mattresses do not perform very well when providing firm edge support. The foam layers will sag in somewhat when pressure is applied near the sides, causing some sinkage.

Recommendation based on sleeping style

Q1. Which sleeping position is ideal for the Simmons Memory Foam mattress?

Here’s a list of how each sleeping position would feel on the Simmons Memory Foam mattress.

  • Side Sleepers: The Simmons Memory Foam mattress is a fantastic fit for side sleepers. Its all-foam built allows the shoulders and hips of the sleepers to sink into the bed, reducing the chances of pressure build-up. The Firm version of this mattress should be a good fit for heavyweight sleepers, as it will provide the best balance of support and cushioning. The Medium and Plush versions are best suited for average to lightweight sleepers.
  • Back Sleepers: Back sleepers require a supportive mattress that provides good spinal alignment. The Medium and Firm version of the Simmons Memory foam mattress is a good fit for the back sleepers. They shall experience the necessary support and some plushness near the hips. Average to heavyweight sleepers should go for the Medium or Firm variants for a better experience. Lightweight sleepers might get the required comfort on the Plush version as well.
  • Stomach Sleepers: The stomach sleepers require a firmer mattress that prevents their spine from bending uncomfortably. The Firm Simmons Memory Foam mattress is best suited for such sleepers. This version prevents the stomach sleepers from sinking too deep into the bed and keeps their bodies well supported.
