I love these stairs and so does my 14 year old 63 pound dog.  They are very sturdy, attractive and easy to move around or change from stairs to a ramp.  I looked at many before I purchased this one and none of the others were as well made.  The wood frame and the carpeting fit in with my decor well and don't have the cheap look that so many I looked at did.  My dog has a very weak arthritic hind leg on which he had surgery two times in his youth and had gotten to where he was not able to jump up on my bed anymore.  He is a very anxious dog and was a little afraid to climb it at first but with a little reassurance from me and a few practice climbs he quickly learned to maneuver the stairs without help.  I would recommend it to anyone who needs a sturdy, attractive ramp or stair for a pet.
