Sheetsnthings Solid 450-Thread-Count, 100-Percent Cotton Queen Size Attached Waterbed Sheets Set, White

Catch up on your sleep with a sheet set made for lasting comfort made of 100% cotton, and woven at 450 thread counts. It's lightweight and breathable. Designed to perfectly fit your waterbed mattress for a snug and secure fit, along with an attached flat sheet to prevent sliding during the middle of the night for a night of uninterrupted sleep. Featuring a Pole Attachment feature that is used to keep the triangular fabric fully opened so the fitted sheet stays tucked in underneath your mattress and doesn’t come off easily. If your bed doesn't include the pole attachment feature, you can insert a 12-inch long wooden or plastic pole that is 1-1.5 inches in thickness (any pole can be used as it’s NOT INCLUDED). That Pole when inserted will keep the triangular fabric fully opened under your mattress and makes it harder for the fitted sheet to come off
