This is a bedwetting sheet from the Australian brand, Connie. It's similar to the waterproof sheets used in hospital beds, but this one is absorbent. The main part is thick and not flimsy. It can be used on both futons and bed mattresses. I used it on a mattress to prevent bedwetting for my child, and while there was a small accident once, it never absorbed a large amount of urine. It can be washed at home and can be used with hot water and a dryer, as long as the temperature doesn't exceed 80 degrees Celsius. I think it's in good condition, but please refrain from purchasing if you are very particular. ■ Size / 100 x 100 cm With tuck-in flaps on both sides (46.5cm x 100cm) to prevent slipping ■ Material / Surface: 100% polyester Middle: Absorbent part 100% polyester / Waterproof part 100% polyurethane Back: 100% polyester ■ Absorbency (8 hours) 2.5 liters Retail price: 6490 yen #NursingCare
