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've washed it at home and stored it. There are no side rubber bands to hold it in place, but the feel against the skin isn't noticeable when it's under a sheet. How about this for those who are starting out in this season? There are some visible stains. Please refrain from purchasing if you are looking for a new item. Thank you. #NitoriWaterproofSheet #NitoriWaterproofSheetBaby #WaterproofSheetBaby Thank you for looking.
