I admit that I had my doubts that a rolled up piece of foam could solve my distressful nights of sleep, but after a month on this mattress, my doubts have been alleviated! This is my first "piece of foam" - I have been laying down on a traditional mattress for 52 years. I never would have thought I would purchase a mattress online that came rolled up in a box, but I gave it a try and what a great product! No more tossing and turning because of hip and shoulder pain!! I have been telling all my friends and family about this answer to lack of sleep. Go by yourself one now! I do not believe you will be sorry.
