After a year in use, the mattress sags significantly in the area where I sleep. Also, it's really hot, which the "advanced memory foam" was supposed to prevent. Ridiculous for a mattress that costs this much to perform so poorly.

I should of not bought the second beautyrest mattress at Sit N Sleep, the first one lasted about 6 years, my fault was that I spilled tea on the mattress so it stained the mattress, therefore Simmons refused even to look at the mattress, that stain cancelled the warranty. So my back was hurting so much, and I went and bought a new Beautyrest Mattress at Sit N Sleep again, after a year, now I started to notice the mattress indented a little on the right side where i lie down on the part. I called them and they sent a third party, and sent me a note said it was normal for that little crater. I don't beleive them, so people DONT BUY BEAUTYREST AND DON'T SHOP AT SIT N SLEEP, they just want to take your money.

I have had this mattress for about one month. It is way firmer than the mattress that I tried in the store. It has softened some during the month but still causes a lot of pain in my shoulders and some discomfort in my hips. I will be returning this mattress as soon as I decide on a replacement. I still have 70 more days to make a decision.
