Zip On Fitted Sheet Twin XL Size(39X80) - Includes 1 Bottom Fitted Base + 2 Zip Sheets - Fit's 12” In Deep Pocket - Zip Sheets Easy to Change - 600 TC Cotton Fitted Sheet - Silver Grey Color

These sheets are perfect for adjustable beds. I recently purchased an adjustable bed and when ever I adjusted it the sheets would move and come off. So these are convenient, easy to put on and with 2 tops you dont have to change the bottom every washing. The price is steep for the sheets, No more moving sheetsbut they do not move and I love them. You can mix and sheet tops.

I was surprised that this set of sheet fully covers the top and bottom of the mattress. There is no way the sheets are popping off. The first install is hard but then you unzip the top part to wash and leave the rest. I wouldn't put these in the dryer. I'm afraid they would shrink and then the zipper wouldn't work. I'm a little concerned about the plastic zipper lasting. So far, I love this purchase. I'm excited to never put traditional sheet on my kids bottom bunk ever again.
