Made to fit Sleep Number beds by Select Comfort. This is standard expanded queen size. This complete shell is for those who need to replace both the top quilted section and the bottom section. This model fits duel chamber beds. The Ultra shell features the same YKK zipper (5cnu) used by Select Comfort. Not only is this shell made in the U.S.A., but all components are as well. We use only the best fabrics, foams, upholstery threads and padding. This complete shell is specifically designed to fit Select Comfort Sleep Number beds; this is not a waterbed encasement that has been re-marketed as a Select Comfort shell. That is why we guarantee a snug fit, just like the original. Questions? Talk directly to one of our experienced craftspeople who sews these covers right here on site!
