SO pleased I researched until finding this ramp! It works on the side Toyota sedan door - is sits a bit angled but still allows our girl to walk up instead of jump poorly with her aging spine. Have it set up for the love seat when not needed for the car. The built-in handle works well for carrying. The rubber-like textured surface is wonderful - great traction. After debating a year on this, saw the PetSTEP last week and knew right away it was the one! Kudos on your engineering!
