This navy sheet is made of waterproof material, so you can use it with peace of mind. It's for a double size bed, 140 x 200 x 30 (cm). I used it once or twice after purchasing it, and then washed it. There may be some dog hair attached (it can be removed), so please refrain from purchasing if you are sensitive or have a dog allergy. - Color: Navy - Material: Waterproof material Thank you for looking.
