I have this exact "Beautyrest Recharge Catskills" mattress model. I am finally exchanging it through warranty. I am utterly shocked that they still not only sell this (since its so awful) but they hiked up the price too??? When I bought it, the regular price in the store was $574.99. However, I got it cheaper than that because I shopped during the memorial weekend sale. How does this same mattress years later cost over $1,000 now? Not that it matters to me... i just dont get it. Anyway, I bought this mattress then my friend who lives in my building copied me and bought it too after a few months of me telling her I was satisfied. BTW, she paid that same low price too. After about a year mine started to cave in the middle, slightly in the form of my body. My friends started getting this effect even sooner, within 6-8 months and she got sever back pain. I dont complain much and not picky especially with a mattress so maybe mine got this effect sooner too but I just didnt realize it I guess. Anyway, we are both skinny girls so it has nothing to do with us being heavy people at all. Bottom line, this mattress was not defective.... its just bad! This is a testament as 2 people bought the same mattress and had the same effects. Anyway, do not buy. It doesnt even cool like it claims in the highlights. I am now exchanging for a more expensive mattress and paying the difference. No way I am sticking to this same model.
