This is a thick, single-size waterproof sheet. The size is approximately 100x210cm. After using it a few times for my child after they finished potty training, I also used it for travel and trips back home, but the frequency of use was low, and it has never been soiled by bedwetting. I used it with a sheet on top and stored it in a closet for several years. It has been washed and thoroughly dried in the sun. One side is cotton and can be machine washed. It's not only for bedwetting protection, but it's also reassuring to have one during the norovirus season. I removed noticeable dust and hair, but there may be some short hairs or feathers from a down comforter remaining. I will take measures to prevent water damage and ship it in simple packaging with compensation via Yu-Packet Post. This item is not eligible for combined discounts. (Thin items like buttons, stickers, and toys are possible. Please inquire.) The packaging materials are reused. There are no pets or smokers in the house.

We will deliver a product that will satisfy you more than the price difference. * 【Reliable 100x210cm】 General waterproof sheets are 200-205cm long, but Ikuzusu's waterproof sheets are 210cm. The difference of 5cm or 10cm will firmly cover the entire futon with余裕. * 【Fully machine washable】 Please wash without using a laundry net. It helps save time on laundry. * 【Tumble dryer can be used】 100 dryer tests have been conducted (in-house test) 【Public quality testing conducted by a third-party organization】 (Quality inspection) Washing, sweat, color bleeding (Water resistance test) 3964mm (Formaldehyde test) Lower adsorption standard (Water-based test) 1 second * 【Thick and sturdy type】 If you're unsure, choose this 100% cotton waterproof sheet! Thin, flimsy waterproof sheets wrinkle easily and are very difficult to use. Because it is a "thick and sturdy type", it is less likely to wear out during washing, so you can rest assured.
