I love the feel of the mattress. However, I am not sure if it provides proper back support for me. I'm trying to give it some time to see if my body will adjust to it, but that question is up in the air right now. I wake up with slight back soreness some days.
The purchasing experience was seamless. Marketing material was honest and insightful, lots of good metrics without gimmicks. I don't know if everyone would like the mattress though, at this point I believe my wife likes it better than I do, we'll see if we make it to 100 nights.
