This is the one. I had to replace my memory foam mattress, and am very happy I bought this mattress instead of a traditional setup. I have a connective tissue disorder so I read a lot, too much, about mattresses before purchasing. I added a 3 natural latex topper and I sleep better than I have in years. 
Upon delivery I unwrapped the mattress and let it expandair out for a day. It puffed up perfectly and the cover is very nice.
