I bought one a year ago. Not sure of the brand or anything else. Got it from overstock. It was one of the highest and most rated mattresses there. Think I paid maybe $600-$700 for it. Not sure exactly how much since I bout it with a bed and other stuff that totally about $2k.
Absolutely love it though. Maybe the most comfortable mattress I have had. Next mattress will definitely be memory foam.
ETA: Oh yeah, it definitely sleeps hot. Only complaint. Have to keep the air down low at night and only use one sheet. Other thing I would worry about is to use a mattress pad or something similar underneath. After a night out of drinking, I tend to sweat or from bedroom activities sweating and I do not want the foam absorbing the sweat through a single bedsheet.
