I was looking for a springless mattress, and took the risk on this one. This is one Kool Mat, the way it comes in a bag, reduced to around 4 inches, and then you open it, and it inflates to 14 inches in seconds. WOW! The mattress is as most have reviewed it. It is definitely on the firm side, but there is wonderful hope, if you put an additional 3 inch memory gel foam topper on it, you will be in heaven!! It's a perfect match! Can't beat that comfort level for the money, no way no how!
