This is a Pet Gear brand step / ramp, or stramp as they call it. It is a great solution to help dogs up and down from the car, couch and bed as it takes up less room than a ramp and is easier for dogs to use than stairs. It worked perfectly for us, except that our dog is not allowed to do jumping of any kind due to a back injury. So he has to use full ramps everywhere, and I no longer have a need for it. Dimensions: Shortest height: 5” Tallest height: 10” Width: 20” Length: 22” Original cost for me was $60, but currently it is listed at $46 on Amazon. Pickup is in Irvine near Alton and Jeffrey, no exceptions. Price is firm. I will not respond to lower offers. Thank you!
