I am selling this because I no longer need it. [High-Density Foam - Provides Solid Support] The interior uses high-density foam, which is also excellent in breathability and elasticity, and does not easily deform. With moderate firmness and cushioning, it absorbs impact and provides stability, reducing the burden on pets' legs and lower backs. Suitable for dogs, cats, and other pets under 27kg, including large, medium, and small dogs. [Gentle Steps for Easy Climbing] The steps have a 30-degree low-angle slope design, allowing older dogs and short-legged dogs to climb up and down smoothly with less strain on their legs and lower backs. It helps prevent injuries as pets can move up to high beds and sofas without jumping. [Removable Cover - Easy to Clean] The cover is made of durable polyester material and can be easily removed with a zipper. When it gets dirty, you can remove it and wash it in the washing machine, keeping it hygienic. [Non-Slip Processing for Good Stability] The area where pets walk is made of fluffy corduroy fabric, which is gentle on dogs' paws and has a non-slip effect, making it easy for pets to climb the stairs. The bottom is also non-slip, increasing stability and preventing the stairs from shifting when pets are on them. [Convenient Handle] The dog step has a handle on the side, making it easy to grip and convenient for carrying and moving during cleaning.
