WOW! I had no idea how something so simple as a new mattress could change your sleep and outlook on life. This is my first time having a Beautyrest. I love the quality of it. It's built to last which is important. What you invest in is VALUE! I look forward to eventually getting a twin at some point. This supported my body perfectly, and I'm slightly overweight. I bring that up because I want you to know, it's high quality. No sagging!
