The base hugs the sides of the mattress and is open on the bottom so it goes on easy over the top. We’ve designed SuperGrip corners with vertical elastic and a box structure plus a generous elasticized overlap underneath so your sheet will stay snugly in place and won't pop off the mattress. The zip sheet attaches easily to the base by a zipper that is covered and out of sight. To change: zip off, and zip on a crisp, clean zip sheet.
First time: Zip together base and zip sheet and slip onto mattress.
