Always wanted to buy one, but they are so expensive in pet stores so when I came across this Cat tree I was so excited. (under $200.00) It has proving to be a great purchase, well worth the money. My 13 pound cat, Mojo loves it even though he is really too long to fit on any of the three platforms, he makes it work for him. Late at night he plays with the toys and I just smile knowing he is happy in his own space up high. The exterior material is easy to clean with a vacuum, it was easy to assemble, and it is a sturdy Cat tree. I do recommend this particular Cat tree.
