I have two cats one is very active, and the other one prefers to lounge around most of the day. This cat tree serve's as both a fun place for cats to play, and take a cat nap.  This product is very easy to put together and it is sturdy. Plus it's a great price!  Anyone who said it was wobbly probably didn't have the screws in as tightly as possible. I would highly recommend this cat tree!
