Don't waste your money!!!

The first mattress I bought at Sears was horrible and they made me keep it for a full 90 days before I could switch it. The sales person went on about how great the iComfort Prodogy Everfeel was so I paid the extra money for it. It was fine for the first year. I've now had it almost 15 months. I started noticing about a month ago that I was in constant pain when I got out of bed. At first I blamed it on my age and on my work outs, not thinking for a minute it could be the mattress. Now I realize its the mattress. The foam has gotten so soft it no longer supports my body. I weigh 150lbs and my boyfriend weighs 200lbs so the problem is not our weight. There is no visible sagging so Sears says the manufacturer can't help me. They made me buy their box spring and mattress pad to honor their warranty but there is still nothing they'll do for me. $2300 for a mattress that lasted one year is ludicrous. Do yourself a favor and stay away from this mattress. I wish I'd read the reviews before I bought it.
