I know Ive only had this mattress for less then a week but I'm comparing it to my beloved Queen size Tempurpedic (which took me 90 days to love). My husband and I have been wanting to upgrade to a king but the Tempurpedics are so $$$$$$. So we were thinking about just getting a cheap mattress with a 2" memory foam topper built in (these mattress sucked). When we were introduced to all the new memory foam type mattress i was shocked at how many were out there. I was scared to get the Serta Icomfort which was close in price to Tempurpedics cheap mattress. The price was the only thing that was comparable between the two. I had to agree with my husband that i felt like we would be getting much more for our money if we went with the Icomfort. We went with the 9" Insight it is a firmer mattress, which i like better. I have had 4 great nights rest in a row.

I'm keeping my fingers crossed that this mattress holds up to its firmness. So far loving this mattress.

We have the iComfort Genius model. This mattress is very firm, but at the same time contours to the body, with what you could call "the marshmallow effect". After seven months of two people sleeping on it, no signs of sag. (I'm 155 lbs, my wife less.) I enjoy sleeping on it very much.

We purchased a new I comfort in late Sept. 2012. They were fairly new and not a whole lot of info. was available, but it had a good warranty, so we bought one. After a short period of time, the mattress began getting soft, and after a few months was sagging over an inch on my side, and an inch and a half on my husbands. We called the store, and they were very nice and said we could switch to another mattress, or retry a new Icomfort. We really liked the bed when new, and hoped we had bought one with faulty foam, so decided to give a new one a try. After a few months the exact same thing happened. I do believe that there is something inherently wrong with the foam they use. I am not sure which part failed. My husband and I are not small people, but we are not humongous. My friend also bought the bed when we purchased ours back in Sept. She is a small person, about 110 lbs. She is also noticing a softening, but hers has not begun to sag. My husband and I weigh about 200-250, and this bed did not work for us. My friend has started sleeping in a different place on her bed every night, hoping to not have the same issue we did.
