Support only lasts a few months then it sags and at night you can hardly move out of the ditch. Unless you want to visit with a chiropractor every week forget this bed.

Ok, yes it smells! Badly! Everytine you move into a new position it's like the gases are released.... It's gross of chemicals! It is like a 3.5 stars out of 5 for us. Still getting used to the memory foam mattress feeling.

We purchased a queen Insight mattress and foundation about a year ago, we hate complaining so left it too long but in any case we are very dissatisfied with this bed.
We read reviews (do not believe the ones on the serta site, they only post good ones) we tried all brands and styles several times and this mattress felt good at the time but that all changed rapidly once we started using it.
Within a few months the mattress lost all its support, its like sleeping in quicksand with sand dunes on either side, you cant turn you cant get out and we have spent more than what the bed cost on doctors, chiropractors and physio since we got it.
Finally even we were driven to return to the store and tell them it is unusable, it has a 25 year warranty, 10 years warranty and 15 prorated so we thought it a safe investment. Only one year and its more than used up its 9 lives.
Today they came and took photos and measured the dips and hills and when they lifted the mattress off we found not only was the mattress junk but that the foundation had collapsed in a 2x4 foot section. I had never even moved the mattress off to check that, I turn the mattress around every 2 weeks but hadn't lifted it off yet.
We are seniors, we aren't heavy and we treat our bed with respect, no way this should have happened within such a short time.
I wish I had found these reviews a lot earlier, they are honest, this bed is trash, do not buy one!
We cant turn over, we cant even get out of it, when I do my knees are up on my chest and my butt feels like its on the floor. There is a huge hard high spot in the center that you cant even turn into let alone get over. I have never had so much pain in my life as since we got this bed and my husband is the same. We fight over who gets to sleep on the sofa.
The support foam underneath the memory foam must be very poor indeed to lose its resilience in such a short time
I sincerely hope they will replace this bed with something that is NOT a serta if not I will contact the BBB and file a complaint and am going to leave my review in every place that takes them so others will not go through the hell that we have.
