Before I bought this, I was going to purchase a similar 10 inch mattress. This was significantly less expensive, such that I figured I would take a chance on it first. I had never slept on one of these before and am very satisfied with the product (I got the firm one because I like a firm mattress). The cooling gel takes a little getting used to, but now when I compare this to a traditional mattress or the one I used to have (where you pick a number for your sleep firmness), I have to say I prefer this one. Also, the price.
