Yellow waterproof sheet with a soft 100% cotton surface. - Brand: NITORI - Material: Surface: 100% cotton, Back: 65% polyester, 35% polyurethane - Color: Yellow - Size: 140 x 100 I bought this when my child was in training pants while we were sleeping together, but it wasn't needed as they were able to potty train! I have washed and stored it at home. There are no side rubber bands to hold it in place, but the feel against the skin isn't noticeable when placed under a sheet. How about this for those who are starting out in the coming season? Please refrain from purchasing if you are looking for a new item. Thank you. #NitoriWaterproofSheet #NitoriWaterproofSheetBaby #WaterproofSheetBaby Thank you for looking.
