I'm not a fan of firm mattresses but have found that I will need to get over that, because as I get older, my back doesn't tolerate really soft mattresses. My biggest complaint about the firm mattresses I've tried is that it felt like I was sleeping on the floor! But the Beautyrest mattress is different, it's firm but also cozy! I can lay on it and feel comfortable and that makes a huge difference to me. I definitely feel the support! My back is a fan!
