Very good mattress that appears to have decent construction. I ordered the softest version and I think it could be a little softer, but I like it overall. I used to have a memory foam mattress. It was really hard in the winter (since I keep the house relatively cool), and sleep pretty warm in the summer. I think this mattress should do the trick. Rather expensive, but mattresses are a hassle to try out and return and I like it enough to keep it and even recommend it to others.
