I bought this mattress about 3 months ago now. It has been one of my better investments. I have no problem sleeping on it, or any thing else anyone can think of doing on a mattress. . Pros: 1. I have found the be to be firm yet form to my body. (I guess NASA knows what they are doing) 2. Friend and Family have also slept on the bed. Some many times some only once. Everyone liked the mattress. 3. Very easy to unpack, and install. 4. Because of the foam thing, you can't tell when someone else gets in the bed. (You know the commercial with the bowling ball and the champagne glasses, this mattress could easily do that. It is a great little added bonus 5. Heat distribution - This mattress does a really nice job of keeping my body at the correct temp. I don't get up in the middle of the night from being overly hot, even though everything else is the same in the house. Temp, humidity, and number of blankets. . . Cons: Disclaimer - I like my bed alot so these are VERY minor . 1. The bed smelled for a couple of days. I just left it in the room closed up, and slept on the couch. I don't sleep well in stinky rooms. Every review typically indicates the mattress will smell in the beginning, so I was aware and prepared for this. 2. The only real complaint I have gotten from any one was "the bed feels funny when you get on it, but after that it was great". I will admitt the bed is a feels little funny when you first sit on it, but after that you don't even notice it any more. . . Things I don't know about; 1. The mattress comes with a mattress cover. I guess you could at some point take it off and wash it, I would imagine it would be a pain to get the cover back on. I have not done this, so I this is only a guess.
