I have been sleeping on our Purple Plus for a month at least now. Yesterday I shoveled snow quite a bit and I was tired, and my back hurt. What relief I had when I finally crawled into our new bed! I have never had such relief when getting into bed. And I woke up with no pain! Previously, I had slept on a Casper, after that we ordered a dream cloud and returned it immediately. The Purple+ is the best mattress I have owned.
