Bought this for my 40th birthday. I didn’t realize I had such back pain until I slept on this for two months and my back felt progressively better. I fall asleep quicker, and get up feeling much more rested than I had on my previous mattress. I didn’t swap a cheap ratty old mattress for this either, I was sleeping on a two year old pillowtop mattress. This is absolutely better. I don’t toss and shift trying to get into a comfortable position, I just plop down on it and I’m out. You might need a helper to get it into place though, it’s heavy.
