I recently moved across country and knowing that my old mattress was 10 years old and a queen, opted to buy a new mattress rather than pay to move my old one. Picked this one up based on a friend's recommendation and I couldn't be happier. I had the experience a few years back of sleeping on a memory foam, and while I liked how comfortable it was, I couldn't stand waking up in a sweat from how hot it made me. This is not the case with this mattress!
This mattress is also extremely comfortable--I opted for the "soft." My body feels softy cradled on the mattress without a pressure point to be found. I look forward to a soft sleep every night. Quick tip--if you buy the soft and it's a bit too soft--just flip it over! The mattress is a bit firmer on the "wrong" side.
