This is Nitori's "Pet Step (N Shield GY)". It's a convenient step that helps dogs and cats get on and off sofas and beds. The N Shield fabric is stain-resistant, making it easy to use. I bought it this year for my beloved cat, whose legs and back have weakened, and used it for about two months. After that, I stored it at home. There are no noticeable stains, and it appears to be in good condition (please check the photos). I hope those who understand that this is a used item will consider purchasing it. ■Size (approx.): Width 40cm x Length 75 (50+25)cm x Height 12cm (24cm when stacked) ■Side fabric: 100% polyester ■Bottom fabric: Base fabric 100% polyester, Non-slip PVC resin ■Filling: Urethane foam ■(Not washable) ■Color: Gray I will use a recycled box for packaging and send it with simple packaging.
