I have two adult cats, who still run around like kittens.  This post and lounge is great for them.  It has a base that is wide enough to keep it steady while they jump and crawl all over it, and the half-pipes provide a great place for napping while still allowing them to see what is going on around them.  I also like the shorter height, so that it is not so obtrusive in the room.  Both of my cats have their claws, and have worn out several scratching posts through the years, so only time will tell how this one will hold up.  So far, so good!
