[This review was collected as part of a promotion.] We had not bought a new mattress in quite a few years. This one is like an old school spring mattress with memory foam on top. The whole thing was 13" where our old one was only 8" It's really quite comfortable. It says it has medium support but I would say it might run slightly more to the soft side. The top has a very thick soft layer of foam but underneath there is support. It's supposed to have some cooling properties and while it's not hot, I do not detect any specific cooling effect. Maybe because we have an extra sheet under the bedding to help protect the mattress. One thing I do like is that when you sit on it it feels like a spring mattress and not just foam. I do not like all foam mattresses so I really like the supportive feel of what is under the foam layer. I read that this bed has extra support in the center so two people do not roll together. I would say it does a good job of that. It does not tend to sink down in the middle which is a good thing. We put this on the old box spring from our old mattress. We put the box spring right on the floor and this mattress has enough height that it looks like it's on a frame when you make up the bed. The cover of the mattress is a dark color which to me seems a little odd for bedding. I sort of wish it was lighter so I did not have to put something white over it to make it so the dark does not show through. I guess though that does make it a little bit resistant to the look of any stains. I do wonder over time how long this mattress will last. In the past we have always had a regular spring mattress and a separate memory foam topper. The thing about memory foam is that it breaks down faster than springs, so I could see this in a few years showing it's age on the topper. Since it's all one piece it's not like you can just replace the topper. The cover feels to me a little loose on the top already and I wonder if over time it will look even more out of shape. I realize I've brought up a lot of points of concern here but we really do love the mattress and the comfort level. I just have some concerns about how long this is going to last without feeling like the top portion has lost it's shape. Overall it's great right now, I'm just a little concerned about the top portion failing early and as a result having to replace the entire thing earlier than just a spring mattress. Still as it is right now it's very comfy and gives enough support to get a good nights sleep and wake up feeling rested and comfortable. It's way better than what we were sleeping on. Thanks for reading my review
