I purchased this new to care for my elderly dog, but the size didn't fit after using it once or twice. I used it with a pet sheet. I've cleaned it with a lint roller and sprayed it with disinfectant, but there may still be some hair that I couldn't remove completely. There's a snag where the thread is pulled when taking the dog out. I haven't used it much, but please understand that this is a used item before purchasing. Outer fabric: Polyester Filling: Expanded polyethylene Size: 40cm x 72cm x 30cm
