I recently decided to trade in my old traditional spring mattress for a memory foam. I was a little nervous at first, but after reading all the reviews I was convinced it was the way to go. I was having trouble sleeping throughout the night and would wake up feeling sore. After a couple of weeks with the Slumber Solutions 12" Memory Foam Mattress, I am sleeping more soundly, waking up less throughout the night and don't feel as sore when I get out of bed. The mattress is firm at first, but softens up after laying on it for a little while. My only complaint is that it does get very hot sometimes. I've heard that without the cooling gel that it is even worse. I've just learned to turn my heat down more and to sleep with one less blanket. The heat factor is the only reason I didn't give it a full 5 stars. Otherwise, I would recommend this mattress to anyone thinking of buying a memory foam!
