Convenient Pet Access: The 5-step dog stair for cars adjusts in height between 30.3-31.9'in, making it ideal for small dogs, elderly pets, or injured pets to easily access car trunks, side doors, SUVs, small vans, trucks, beds, sofas, grooming or vet tables. Sturdy and Safe: Built with a sturdy aluminum alloy frame, the folding pet steps can support pets up to 150 lbs. They remain stable and do not wobble. Foam handles and safety tether clips enhance safety, preventing pets from slipping while climbing. Comfortable Stair Surface: The dog car stairs are covered with polyester fabric, providing a relaxed, non-slip surface that gives your pet's paws good traction for easier climbing. The bottom non-slip pads enhance stability and prevent pets from slipping on the ramp.
