  • Nice matress
    Verified Purchase

    I've had this matress for almost a month and I like it a lot. It molds to my body perfectly but doesn't sink in. The gel top does make it cool enough. Although I haven't tried it through summer yet. I injured my back and I was afraid it would be too soff and it's not . The only thing I have to get used to is when I turn to my sides I have to grab onto the head board as it doesn't have the spring that regular matresses have to assist you with turning. Although it is probably healthier as I use more body muscles but with my back injury it was a bit hard before going to the chiropractor. I would totally recommend this matress. Good deal for my money too.
