Coming down the pet stairs was proving difficult for my pet. The vet recommended pain pills, which made him a bit loopy. So, I tried the ramp. It took me time to put it together because the screws weren't marked the same as the instructions, so I did spend time taking it apart because I'd used the wrong screw in the wrong place. But, once put up, my pet adjusted instantly. The ramp runs the length of the bottom of my king-sized bed. It works.
