It is extremely large (almost too large).  The cats like it.  The only thing I don't like is that the carpet/fabric/fur that covers it has no nap - there is nothing for the cats to dig their claws into.  Seemed like we were going to have a real accident a couple of times when they jumped to it and couldn't get purchase on the fabric and almost fell.  But you know what they say about cats-mine are about 8 out of 9 lives now.
