Our Verdict
Beautyrest Silver BRS900
Beautyrest Mattress
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.
