I am selling this because I no longer need it. Product Dimensions: 57cm depth x 40cm width x 40cm height Assembly Required: No Number of Layers: 3 Dog Breed Size: Small 【Designed for Small Dogs】This dog stair has a soft, curved step design, making it safe for puppies and pets with weak joints.

It is vacuum-compressed, and the shape will recover in 24-48 hours after opening. 【High Density and Strong Support】This dog stair can support a maximum weight of 36kg. It uses 30D high-density sponge to reduce the burden on the pet's joints while providing stable support. The surface is covered with a corduroy cover to enhance the safety of the pet step. Be sure to attach the cover before expansion. 【Easy to Clean】The dog stair cover is removable and can be washed in the washing machine or by hand. A TPU waterproof layer is applied inside, adding water-repellent function. The sponge part of the dog step cannot be washed, but it can be protected by the cover, making it easy to keep clean, and it is lightweight and convenient to move indoors and outdoors. 【Waterproof and Safe to Use】This dog stair has a waterproof surface, so you don't have to worry about accidental leaks. The bottom is made of non-slip nylon material for increased stability.
