I am so Happy I ordered this cat tree!  It is sturdy and because of the smaller base it doesn't take up a lot of room.  I read in other reviews the that the top perch is wobbly.  Yes it is a little but it is also my cats favorite spot in the whole house. If it were going to come off it would have by now.  My cat runs up the tree to the top at full speed!  It is saving my furniture because my cat actually uses the scratch posts.  I've had scratch posts before but my cats never used them.  They love these!!  It was easy to assemble.  I highly recommend this product!! 

Pros: Durable, sturdy, CATS LOVE IT!
Cons: top perch a little wobbly
