I actually ordered two of these matresses, one for myself and one for my 25 year old nephew. I also ordered 3 " toppers, but with our without, the matress is super comfortable. My nephew, who is about 190-200lbs said it took awhile to get used to as the matress forms around you and when you move it take a little while for the indentation for refill. Aside from that, he said it was very comfortable. Since I am about 125 lbs, I don't really have this issue. Great value for the price and what you receive. I would recommend to others (and have)! I would recommend the 10-inch over the 8. It is more matress like. Even with the topper, my sheets fit, albiet a little snug. Overstock was great and delivery came quicker then I anticipated. Great Job Overstock!
