We owned our old mattress for 20 years and routinely flipped it. In the last couple of years my wife would wake up with aches and pains so we shopped for a new mattress. I researched for hours, shopped around, and bought an iComfort. It really felt great in the store, and felt good at home for the first two months. We did not need to "get used to it" we both slept fine. I began to wake up with some lower back pain but attributed that to increased driving for work.

After 3 months we both had trenches, soft patches, where we slept. The foam would bounce back just fine, and the mattress was flat on the surface, but the places we slept lost significant support. If you slept in the middle of the bed or laid across the bed it was fine. It wasn't as bad for my wife who sleeps on her side, it was terrible for me and I continued to wake with lower back pain.

Two days before the "no hassle return" we returned it. If the foam loses its snapback after three months we figured it was not going to last 5 - 10 years. Of course we felt bad sending a mattress to the shredder but after the 120 days the mattress would need a sustained 2" dip to breach its warranty. This would never happen and we would be out $1000 bucks.

Our options were to go for the $4K Tempurpedic or move back in time to a hand made mattress and box springs. We did the latter. Bought a Shifman for the same price, about a $1000. It has a real box spring and an incredibly heavy cotton stuffed mattress. We are BOTH sleeping great. I have no pain sleeping on my back or stomach, my wife sleeps great on her side. The technology in this brand has not changed for 75 years and folks get 20-30 years out of them, flipping side to side or end to end every couple of years if they feel less support.

I wish I would of found this forum before I bought my Queen sized iComfort Insight matress with adjustable base from Serta. In the store it felt pefect and the price was half the price of the Temperpudic. When we got the matress it was hard as a rock, the delivery guy said it was in the truck all night and it was below freezing that night. He suggested give it a few hours before laying on it.

It did soften up quite a bit but for some reason I can't even get comforable on this matress. I have a bad back and it has made it much worse. I felt better on my 12 year old spring matress. We will be returning the mattress and getting the Temperpudic.

It is not worth saving a couple thousand dollars and getting no sleep.

After several months of mattress shopping, we settled on the Serta I-comfort Genius queen bed set because it was advertised as extra firm. My husband and I are both large, tall people.The salesman assured us that this mattress set would support us comfortably, would recover (any indents our bodies made would go back to flat) and that it was guaranteed for 20+ years. We have to say that for the first 10 days or so, the mattress was very comfortable. But around the 11th day it started to sag and would not recover even when we skipped a night sleeping on it. The edges broke down immediately. We contacted the dealer and he told us to rotate the mattress and try it for another few days. We tried it for 2 more weeks. During that time I slept uncomfortably in the "hole" that my husband made when he was sleeping on that side during the first 4 weeks (he outweighs me by about 90 lbs). We have since returned the I-comfort mattress to the dealer and have been sleeping on the floor on a $399 Costco memory foam mattress ever since. We are going to build a platform and put the Costco mattress on that and hope that we finally can get a good night's sleep!
