This is the first memory foam mattress I have owned (been sleeping on it for a little more than a month) and I am glad I made the switch. I had purchase a firm mattress previously as I thought I wanted that...I was wrong. Had put a 3 inch memory foam topper on it and that improved it substantially, but we also needed to move up to a king size (the dogs sleep on the bed). I normally wake up with a sore back and hips--no more! This mattress has the right amount of give, but still a sense of firmness that gives support. I also sleep through the night now--not something that was happening before.
