Our Verdict
Beautyrest Silver BRS900
Allswell Hybrid
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.
