This mattress is perfect for my back. Soft, but firm enough to give my back support. We have an adjustable bed. This mattress is compatible with our adjustable frame. It has cooling technology to the touch. Unfortunately I always use a mattress protector so you cannot feel the cooling technology through that and the sheets. I wish I could feel it through the sheets because it feels amazing. I sweat a lot at night. Thats kind of a disappointment. It took a few hours to open up fully and expand all the way since it comes in a box. Which is super easy to get through doorways and unpack.
