Sized for smaller vehicles and lighter dogs, this four-step aluminum car stair adjusts between a 25.4-inch normal stretch and a lower 24-inch angle, letting you fine-tune the incline for a sedan trunk, side door, or a bed or sofa at home. The aluminum alloy frame stays stable under dogs up to 150 pounds, and polyester fabric on every wide step gives paws a soft, non-slip surface, backed by non-slip pads on the base so the stair doesn't shift once it's positioned. Foam handles and a safety tether clip help you guide your dog up with confidence instead of lifting them by hand. At only 9.17 pounds, it's the lightest stair in the lineup and folds down to a compact 16.9 x 13 x 6.3 inches, small enough to tuck into a trunk, closet, or under a car seat when it's not in use.
