Purchased the medium and it is as to be expected for a bed in a box. However, the mattress is 6" smaller than a standard King sized mattress. Therefore, it does not fit correctly on the bed frame. Which is highly disappointing since the closest place to return is 100 mile drive.

Very firm but great

Purchased the KS Firm and couldnt be happier. It molds perfectly to your body and offers excellent support. Cooling layer is really effective. I was worried about the memory foam being too hot for me but I really didnt need to worry at all. I will certainly be buying these for my other beds.

I love this mattress.I paid a small fortune for our old mattress and this one is so much more comfortable.

Bed was nice at first but then 3 months later it lost its luster and started getting soft. Going to return.

Mattress sleeps very good. Makes back feel good in the morning.

The plush mattress is like sleeping on a marshmallow. You totally sink into it. No support whatsoever. And I like a softer mattress. But not this. Also, there is NO reason for it to be 14 inches thick. Making the bed is a nightmare and keeping some expensive deep pocket sheets on it is impossible. Have had the mattress on a guest bed just a few months. Will be putting on the curb for garbage pickup soon.

Painful after lying in it for an hour or so. I bought this a few months ago and was hoping I'd adapt to it but so far no good.

Very happy with this purchase! I was a little worried about the "bed in a box" idea but its great quality and gives a good night sleep.

Had high hope based on prior reviews. Purchased the first of Sept and so far for 2 1/2 weeks it has exceeded my expectations.
