I have a Scottie terrier that is 10 years old and finally got to the point where she almost misses trying to jump on my high bed.  Bailey is short legged so I looked around at different stair sets looking for a set with wider, carpeted steps that are sturdy.  I ordered these and they came in 10 easily-assembled, well-marked pieces.  I had them together in about 15 minutes.  It took me a lot of treats and a couple days but Bailey was finally enticed to go UP the steps after a few times of me lifting her onto the bed and her going DOWN the steps.  All-in-all it was a great purchase!
