I've only been sleeping on the mattress for a week. I find that I am getting a better nights sleep and I don't expect that to change for the long term; however, I don't tell other people what to do unless they ask. Am I satisfied? You bet I am.
I haven't slept good for years and ever since I received my new Tuft and Needle mattress I have no problem falling asleep and staying asleep, I don't wake up sore anymore either.
