This mattress is not full the full size length of 25 inches a advertised. Its only 74" and it makes a difference to me as my toes touch the edge and swoop down.

This mattress performed well at first, but by year 3 I began experiencing back pain. The mattress begins to sag where your heaviest body weight is and you begin sleeping in a sagging depression. I contacted Serta (03022079) about warranty coverage and they will keeping pushing it back to the retailer, and Serta will not honor their warranty. They rely on employees from the retailer who come over to "inspect" the mattress, however they don't place any weight on the mattress to test the problem of sagging. They'll tell you the mattress is "conforming to your body", however what I need is a mattress that retains it's original structural integrity and supports my back. I would not recommend this mattress, or Serta. I paid over $2200.00 for a mattress that ended up causing pain.

We bought this bed in hopes that it would be the answer to our problems. We do not like it at all. We liked it for the first month, and then we started having back pain. Now we are stuck with a $1700 mattress.

I had a Costco memory foam mattress prior to purchasing this iComfort CF4000 Hybrid mattress. I purchased two of the twin XL's to form a split king. First off, absolutely ridiculously expensive, but they get you as the claim is it improves your way of life. I fall for this, as it's true and all the competition is very close in price. Still over-priced, okay I'll get off my high horse now. The mattress was not as impressive as all the reviews and everything else I've heard. Especially compared to another memory foam mattress. It is noticeably different, but debatable whether it's worth the cost. My wife claims the old far cheaper memory foam mattress is more comfortable. It was over 10 years old and needed to be replaced either way, I was just hoping for more of an improvement with our sleep and pains this mattress. I sleep about the same as I did before and it's now been a year since I purchased the mattress. Mattresses are one of those things that no matter how much you read or check them out, it's a purchase you are stuck with no matter the outcome. It's not garbage, just not the miracle remedy that everyone claims. If people are claiming a miracle, they were paid to fluff up the positive and ignore the negative! I cannot comment on how this mattress compares to other competitors of the same quality. I did go off my sisters advice, that has purchased 2 other major (high profile) brands and likes this mattress the best. She has neck and back pain as I do. We are all middle age and above average in weight. I am 6'2'' and my sister and wife are 5'2". I fit just fine on the mattress with no problems of the length. We all are hot sleepers and the CF4000 helps a lot in that category. That is most definitely one of the biggest improvements over our last memory foam mattress, which as normal with them are very hot. We tried a 3" latex foam topper (which we had already and wanted to see if it improved the mattress) and it eliminated that cool effect of the CF4000, so we removed it. I just purchased a GB adjustable bed frame to go with this mattress and hope that also improves our sleep. Again outside the expense, people rave that they help a lot. They are over-priced as well. Again what price tag would you place on "Quality of Life"? That's how they get us and we still buy them, so we justify the cost/benefit...

This product support and gives the comfort my body needs. The cooling features make sure I stay nice and cool in the summer. The look i give it a hundred the only problem i have is the sheets wont stay on because it is a slippery mattress. I would recommend
