Seems to be of good quality, design, and construction. These comments are made at one week after purchase, so durability remains to be seen. The mattress is firm and supportive, as we wanted, yet also soft on the top layers to prevent body-part numbness (when sleeping on one's side). For registering, I did have difficulty locating the requested Serial Number -- better that Sealy in its registration instructions provide a photo/image (like so many other companies do) of where to find the Serial Number. There are a confusing host of other numbers dispersed on the mattress tag and "Warranty Post Label on Boot end".
