Doesn’t hold up

by: Ben1999

No, I would not recommend this to a friend.

Source: serta.com

Was great for the first few months but soon my wife and I were sleeping in the trenches made by the collapsing mattress. We often had to “climb the ridge” in order to kiss goodnight. After a year, we are in the market for a new mattress because we both are having back and neck issues. Definitely does not hold up over time. We’re average weight, probably less than average really, and the mattress just sagged over time. We rotated (not suppose to flip this kind) but that just meant my wife would sleep in my trench and I would sleep in hers.

The Cooling Actually Works!

This bed is amazing! It actually replaced a ten year old Tempurpedic, and we have found the Sealy more comfortable than the Tempurpedic was new. The cooling technology really works, and I have the Sealy cooling mattress cover ordered and on the way!

Actual size 74x80... 2” narrowed than a king

Big problem! The bed frame we bought to go with mattress does not fit this mattress right because it is 74x80 NOT 76x80 which is a king..... we are returning the mattress, the outside edges are not supported properly by the frame Its too bad its a NICE mattress but not a true kind size bed, 2” doesn’t sound like much until it doesn't fit your frame Buyer beware

Best sleep we have had in a long time.

We just love this mattress. We have been sleeping on it for over six months now and we could not believe the difference from our worn 15 year old mattress and this new firm Serta mattress. We get such a good nights sleep now. It's wonderful. No more restless nights. I highly recommend this mattress.

After only 18 months this mattress has failed.

. In the begining it was a good sleep experience. Now after only 2 years there is no support where I sleep. It feels as if I have fallen into a hole which is difficult to get out of. The side where I sit to dress has no support and compresses to the foundation. I would caution anyone who is considering this to be careful in there choice.
