【SMALL DOG STAIR】 The design of the gentle and comfortable curved ramp is more suitable for puppies and pets with knee injuries. It is a pet stair for small and medium-sized dogs. COZY KISS sponge dog stairs are designed to lean against the edge of a bed, sofa or other furniture. Please note that due to vacuum compression, the sponge needs time to rebound. Just cover it with a leakproof cover after opening it, and wait for 24-48 hours for it to rebound completely. | 【DURABLE & LIGHTWEIGHT】 - 30D density pure foam has better support and protects the dog's knee joints. The soft wool cover can reduce the pressure on the pet's joints and provide greater climbing comfort for puppies and kittens. The sponge material is light and easy to carry, can be used indoors and outdoors, is reusable and durable, and is not easy to deform. | 【EASY TO ASSEMBLE or CLEAN】For easy transportation, the dog stairs are purchased in vacuum COMPRESSION PACKAGING. After opening the vacuum packaging, cover it with a leakproof cover. After 48 hours of complete absorption of air, it will return to its original stair shape. Wait for the shape to recover. The leakproof cover supports machine washing or hand washing. Note: Please do not wash the sponge foam. | 【LEAKPROOF & NON-SLIP】The climbing surface of the dog stairs is made of waterproof and leak-proof materials, so you don't have to worry about your dog peeing on the stairs. The bottom is made of non-slip nylon to minimize the movemnt of the stairs. The sides of the stairs are made of wear-resistant cotton and linen for dogs to sharpen their claws, and there is a convenient handle at the back for easy carrying. | 【NOTE & CHOOSE】NOTE: This STAIR IS NOT FOR LARGE DOG.
