We bought a king and full size at the same time.We took a chance by buying without testing but you can't really test that much in the store anyway. We love it. I have not woke with my back hurting since sleeping on it. I think it's been about 2 months since we got them. The only negitive is,on only the king size mattress the corners seem to want roll up a little even with no sheets on it. Maybe there is a fix for it.I have not called them to ask about it.
[This review was collected as part of a promotion.] We bought a full size for my two year old son, who has been cosleeping with us. I have moved into his room/bed with him to help the transition, and it is quite comfortable for a pregnant mommy and toddler to share. I think he will get many years of use out of this bed, and it'll be a good guest option over the holidays. It still has a chemical odor after a few weeks that is noticable when the door to his tiny room is shut, but seems ok with the door and window open.
I was having so much trouble sleeping before I purchased my Casper. All I can say is WOW. Life changing. I can’t get out of bed in the morning, this bed is so comfortable. I was hesitant about the price at first, but it is worth every penny. I haven’t slept this comfortably in my life.
