Well, the mattress itself is comfy. I have been buying pillowtops/plush for as long as I can remember. I am a stomach sleeper, and always had constant lower back pain, and after some research realized I needed a firm mattress. The mattress arrived quickly, and the delivery company was great, and yes, they did take the old one with them! My only issue is that the dimensions are off... when measuring for a bed, in regards to the headboard, they HAVE to be accurate. The mattress itself DOES NOT have a pillowtop, and measured 10.5 inches. The low profile foundations came in at 5.5 inches. In total, we lost 1.5 inches in height and had to build up the slats, and thankfully the bed that we purchased has siderails high enough to do that. I have only slept on it a few times now, but I have woken to NO BACK PAIN, thankfully! Just be aware that the measurements may be slightly off, as it could be an issue for you... Dad I known we were going to need the 1.5 inches, I would ave purchased the standard sized foundation.
