Built for the biggest dogs, this extra-wide four-step car stair uses a heavy-duty metal frame rated to support up to 400 pounds, the highest capacity in the lineup, so it stays rock solid under large or giant breeds. Two adjustable height settings let you match the stair to a car trunk, SUV, or truck bed, or set it up beside a tall bed, sofa, or vet table at home. Instead of fabric, the wide steps use a metal wire-mesh platform coated in durable PVC plastic, giving paws secure traction and holding up to repeated outdoor and indoor use. Foam-padded handles and a safety tether clip help keep your dog steady and confident while climbing. At 14.99 pounds, it's still light enough to lift in and out of a trunk, and it folds for storage in a car, garage, or home corner. It's a dependable pick for owners of large dogs who need real weight capacity.
