I'm reviewing this mattress after only having it for a few days, so I may be a bit hasty. However, I can say as of right now, this mattress is so worth the money I didn't spend on Select Comfort. A similar mattress from them is $2,000+! Delivery wasn't the best; UPS left it at my upstairs neighbor's door, with no notice to me. I just happened to check the delivery status online. So I had to drag and push a 70 lb box several feet to my own door, unpack, and drag the mattress inside. Setup wasn't too difficult, though the foam rubs and drags against foam, so more often than not, I was wrestling with the pieces. The memory foam is slightly longer than the frame, so right now, it's bulging at the end, and one of two zippers closing the entire mattress cover popped off with very little effort. My sheet is being held on with sheet straps, as the bed is so thick, only deep pocket sheets will fit decently. The controller only goes "Soft" and "Firm," and the motor is louder than I expected. But it firms up very nicely, the memory foam is incredible, and the cover is so much softer and nicer than my previous mattress. And besides, the memory foam itself is a separate topper you zip into the cover; very easily replaceable, if it loses density.
