The Beautyrest Silver BRS900 is a mid-range innerspring mattress. Its 'Dual Cool' cover material and corrugated foam comfort layer are advertised for cooling, while its pocket spring support layer helps with motion isolation versus other types of springs. This mattress also has additional memory foam in the lumbar area.
Our Verdict

Average Weight

Heavy Weight
The Beautyrest Silver BRS900 is best-suited for heavier side sleepers. It offers good body conformity and adequate support for people in that weight category, so your shoulder will sink into it enough to relieve pressure, but your hips will stay reasonably supported. It's not a bad option for average people, with decent body conformity, but you might prefer a plusher mattress to avoid putting pressure on your arms and shoulders. Finally, as you'd expect from a 'Medium-Firm' mattress, it's not ideal for lighter side sleepers. It offers poor body conformity for lighter people, so you won't compress it enough for comfortable side sleeping.
Decent body conformity for average people.
Great body conformity for heavier people.
Highly contouring feel helps with pressure relief.
Poor body conformity for lighter people.

The Beautyrest Silver BRS900 is best suited for lighter back sleepers, but is also an okay option for people in other weight categories. It offers decent support for lighter people, which helps ensure your hips don't sink in overly far. While its pressure relief performance isn't great for lighter people, as you won't sink much into its upper layers, its highly contouring feel helps with pressure relief. It's also fairly supportive for people in the average and heavier weight categories, so while it's not a bad option for back sleeping, it won't keep your spine completely aligned when you're sleeping on your back.
Adequate support for average and heavier people.
Highly contouring feel helps with pressure relief.
Average and heavier people may need more support.

The Beautyrest Silver BRS900 is best-suited for lighter side sleepers. It offers satisfactory support for people in that weight category, so it does a decent job of keeping your spine aligned when sleeping on your stomach. That said, you may prefer an even more supportive mattress for stomach sleeping, where support is especially important to keep your back from arching. Similarly, while it's fairly supportive for average and heavier individuals, its performance isn't sufficient for stomach sleeping.
Adequate support for average and heavier people.
Average and heavier people may need more support.
The Beautyrest Silver isn't a durable mattress. None of the foam layers is dense enough to meet the standard for good quality, so they'll degrade faster than higher-quality foams. As a result, you can expect the mattress to sag and lose its shape more quickly than models made with better-quality foam.
Uses only low-quality foam.
The Beautyrest Silver BRS900 offers different levels of pressure relief depending on your weight. This 'Medium-Firm' mattress offers great body conformity for individuals in the heavier weight category, who will compress it sufficiently to relieve pressure when sleeping on their side. It offers decent body conformity for average people, but average side sleepers may want a mattress with better conformity for comfortable side sleeping. Its performance is worse for lighter people, so it's not a good choice for side sleeping, where pressure relief is especially important. The sleeping surface is highly contouring, creating a hugging feel that helps with pressure relief. However, you'll hardly sink into its upper layers, so it's not a very enveloping mattress.
Decent body conformity for average people.
Great body conformity for heavier people.
Highly contouring feel helps with pressure relief.
Poor body conformity for lighter people.
The Beautyrest Silver BRS900 isn't extremely supportive for anyone, but it offers okay support for most people. It's decently supportive for lighter people, so it'll keep your spine aligned well enough for back and side sleeping. It offers adequate support for average people, and slightly worse support for people in the heavier weight category. While it's supportive enough for side sleeping, it's not ideal for back or stomach sleeping, where you may require more support to maintain spine alignment and sleep comfortably.
Adequate support for average and heavier people.
Average and heavier people may need more support.
The Beautyrest Silver offers very good cooling. It should keep you cool and comfortable throughout the night if you don't typically experience overheating while sleeping. However, for hot sleepers, it may not be sufficiently cooling, especially if you're often bothered by heat during the first hour or so in bed, when trying to fall asleep.
Good cooling.
The Beautyrest Silver offers decent motion dissipation. As a spring mattress, it doesn't isolate movement as well as all-foam mattresses, but it features pocket coils, which transfer less movement compared to continuous coils. When your partner rolls over, you'll feel some motion in the lumbar and head areas. However, it dissipates quickly, so you won't wake up with every little movement.
Motion dissipates quickly, so you only feel motion briefly.
You'll feel most movements, so it's not ideal for sleeping with a partner.
The Beautyrest Silver is very responsive. This mattress is primarily composed of polyfoam and pocket coils, and it recovers its original shape almost instantly after being compressed. You won't feel stuck in place, which is especially important if you frequently change positions while sleeping.
Fantastic responsiveness, so you can easily change sleeping positions.

Popular Mattress Comparisons
The Beautyrest Silver is a hybrid mattress with fantastic edge support, making it a particularly good option for individuals with mobility issues or those who often sleep close to the edge of the bed. While it's fairly good at cooling sleepers throughout the night, hot sleepers will prefer options like the Purple Mattress, since it offers much better cooling performance, especially while falling asleep. Just know that this mattress has a more contouring feel.

The Beautyrest Silver BRS900 and the Sealy Posturepedic Plus Mount Auburn have different strengths. They're both medium-firm, but the Beautyrest contours around you more, while you'll sink more deeply into the Sealy's upper layers. The Beautyrest is bouncier and more responsive, so it's much easier to move around on. The Sealy has a slower-moving feel, but a better motion dissipation performance, so you might prefer it for sleeping with a partner.
The Beautyrest Mattress is better than the Beautyrest Silver BRS900. Both have a medium-firm feel, but the Beautyrest Mattress is more supportive for all weight categories and offers better body conformity for heavier people. This makes it a stronger option for average/heavier back sleepers and heavier side sleepers. It also offers better motion isolation, so light sleepers may prefer it. The Silver has a more responsive feel, which you may prefer if you move around a lot in your sleep.
The Allswell Hybrid is better than the Beautyrest Silver BRS900 for most people. Both are Medium-Firm mattresses, but the Allswell offers better support for most people, so it's a better option for back/stomach sleepers, especially those who are average-weight and heavier people. Its cooling and motion dissipation are much better. However, if you prefer a very responsive, bouncy mattress so you never feel stuck in place or hugged, you might like the Beautyrest.
