I ordered the stairs because we of a very large dog (unfortunately died last year) have switched to 2 very small dogs. The two Minis are not able to jump on the sofa, which, incidentally, they should not do so for health reasons. So I had the great and especially ugly ramp that we still (was the big dog is no longer alone in old age in the trunk) from ancient times made the sofa. Because the thing constantly bothered, I decided to buy a "dog stairs" I never really wanted to. Optimal is that the stairs exactly the color of our bed and also almost the same height. It took a few days until my two dogs had figured how to use the stairs, but now she is very helpful and I do not have to constantly bend over to the dogs to lift the sofa. For us a top product that deserves more than 5 stars.
