Beautyrest’s BRS900 extra firm mattress is just the mattress we needed! I didn’t think that a good mattress is so important for your entire day (and night of course!) until I slept on this one. What a difference it has made! I sleep so well, I feel well rested every morning, my day becomes even better because of that. It’s got an antimicrobial performance layer that works to keep my sleep temperature ideal! This is a very well designed mattress for people like myself who prefer to sleep on the stomach and back, I love it! I would highly recommend giving it a try.
