PROBLEM TO BE SOLVED: To simply and efficiently perform a large amount of works for exchanging sheets for covering mattresses in a hospital, a sanatorium, or the like, and to shorten time for works related to collection and delivery and washing. SOLUTION: Colored threads are sewn by a required length along the longitudinal direction from both ends in the longitudinal direction at a specified position from one end side in the width direction of a rectangular sheet fabric 3 being formed longer and wider than the mattress 1 to be covered in the hospital, and by folding both ends in the longitudinal direction to the back surface side, the sheet is partitioned in a sheet surface part 5 and a back surface covering part 6 and the sheet surface part 5 and both ends in the width direction positioned on both ends in the longitudinal direction of the back surface covering part 6 form mattress inserting parts 8 by freely removably fitting parts 7, and there exist no-sleeve opening parts 9 transversely opened on both ends in the width direction by forming the mattress inserting parts 8, and on both end sides in the width direction of the sheet surface part 5, outsides from the mattress are constituted as side laid-in parts 10. |
