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 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.
