Best pet stairs ever. Foam is extremely dense and supportive and the fabric is nice and heavy and durable. The fabric color choices are terrific. The tops of each stair has a nubby textured fabric making it easy to navigate. My blind cat doesn't hurt himself bumping into them going up and down from my bed, and I don't break a toe on it in the middle of the night. Cover zips off easily and does not shrink when washed. (I did not put it in the dryer). Easy to zip back on.
