This wide four-step dog car stair is built from a sturdy aluminum alloy frame that supports dogs up to 250 pounds while staying stable and wobble-free. It adjusts between a 34.8-inch normal stretch and a lower 26.8-inch angle, so you can match the incline to a tall SUV, a sedan trunk, or a lower side door, giving small dogs, elderly pets, or injured pets an easier path up. Each wide step is wrapped in polyester fabric for a relaxed, non-slip surface that keeps paws gripping securely, and non-slip pads on the base stop the stair from sliding once it's set down. Foam-padded handles and a safety tether clip add extra security while your dog climbs. When you're finished, it folds down to a compact 20.1 x 17.3 x 6.3 inches and weighs just 12.79 pounds, so it's easy to store in a trunk or carry between the car and the house.
