Four foam steps climb to bed height, rising through 5, 10.5, 15.5 and 20 inches so a short-legged or older dog can take the whole run in even strides. High-density 30D sponge fills the body, firm enough to hold its shape under 132 lbs and soft enough that a jump down lands safely. The triangular profile is broad at the base and does not rock, and there are no hard corners or edges anywhere on the ramp. A high-friction suede cover grips paws on the way up, and silicone paw prints on the underside stop the steps drifting across a wood floor. The cover unzips for machine washing and a lint brush is included. The whole unit weighs 6.5 lbs and measures 28.5 inches long.
