Like a typical guy, this mattress advertises 8 inches when it is really only 6 inches. But wow, no viagra needed for this bed. It’s about as firm as it gets. So firm it kinda hurts actually. That being said, I’ve been sleeping long and hard on this bed, usually 9-10 hours with little interruption. But make sure to get a topper pad for it unless you like to wake up in a little bit of pain.
