Great mattress and the 100 night no risk warranty is unbeatable. Also returned mattresses are donated and mattress comes to your house in a vet manageable box
I have severe back and knee problems, and I purchased a tuft and needle mattress in the hope that it would help me sleep better and wake in less pain. I've only had the mattress for about a week, and it seems fairly comfortable, but I haven't yet noticed an improvement with my pain. Still, for the price, this is the nicest mattress I've ever had, and I'd recommend it to my friends and family, but with the warning to give it some time for their bodies to adjust!
I choose a 10 because now I can sleep without pain, I have not seen one bad review, every person I know that has one raves about how great it is, and now I will as well.
