After doing a lot of research and reading many reviews I decided on this cat tree and couldn't be happier.  It's incredibly easy to put together and unbelievably sturdy.  I love the color and soft yet sturdy carpeting.  The size is perfect for my NYC apartment.  I knocked off a star as I wish the round perches were a little bigger.  My cat is about 12 pounds and while she gets up there and sleeps I wish she had a little more room.  She loves getting on top of the cat condo and staring out the window too.  It's a great size, well constructed and looks amazing in my place.  I highly recommend it!

Pros: Great value!  Easy to put together, sturdy, a beautiful tree!  Love the materials.  
Cons: I only wish the round perches were a bit bigger for my 12 lb cat.  She fits in them but it's snug.
