My cat took to it quickly.  I got the stairs because I bought a new bed where the top of the mattress is about 30 inches from the ground, and my small 20 year old cat cannot jump that high.  Initially, she was fine going up the stairs but still tended to jump down from the bed, but within a day or two she was fine walking down the stairs.  They were easy to put together and seem very sturdy.  The faux fleece has a nice look to it.  Also much more reasonably priced than other stairs of a similar height.  Very highly recommend this product!
