For years now, I have dealt with chronic back pain and unexplained fatigue. Turns out my old mattress was partly to blame. When I first sat on the Beauty Rest Black series, I knew it would be beneficial. You get what you paid for, beauty rest. I’ve had my current mattress for a month now and have already started to notice an improvement in my pain and quality of my sleep. I’m glad that I’ve invested into this mattress, it’s a good one.
