Mattress with sheets

Abstract

This product is a mattress-attached sheet in which a mattress is covered with a sheet. As shown in the "bottom view of the sheet laid flat," the sheet in this product is formed so that, when viewed from the bottom, the width of the short sides is shorter than the vertical width of the long sides surrounding the opening for inserting the mattress. Therefore, as shown in the "bottom view," this product appears to have an extremely short width at the short sides of the sheet. Because the width of the short sides of the sheet is extremely short, it is easy to reach the corners, making it easy to remove the mattress (and also easy to insert the mattress into the sheet), and because the vertical width of the long sides is wide, it is possible to prevent the mattress from slipping out naturally.
