I've slept everywhere; cots, ground, hammocks, futtons, floors, seats of cargo aircraft, etc. and some really nice mattresses. I have had this mattress around a month and have had the best sleep ever. No hot spots, no back aches, no sore joints, no limitation on which side you can lay. Total comfort. A previous review mentioned having to let the chemical smell go away. It's gone. It started dissipating after I removed it from the packaging. It also 'inflated' within a few hours. My only concern was that DHL had it listed as a Queen mattress, when I ordered a Full. It was just the way DHL labeled it and Overstock had it correct and the Customer service rep was very helpful. It you need a great mattress, and don't want to spend a fortune at the 'Bedding Boutique', this is your mattress. I had shopped before buying and $800 was the price which included a foundation I didn't want or need. I will be buying another when the kids outgrow their twins.
