This product was very easy to assemble and is quite sturdy.  It fit nicely into a corner of our living room behind an end table next to a window.  We wanted the cats to be able to enjoy it and be with us, but didn't want it to be an eyesore.  We chose the light tan color which closely matches the color of our walls.  When people enter the room they don;t even notice it unless one of the cats is sleeping on the top level.  One of them usually is because the sun shines in on it and it's a great spot for bird watching!

Pros: Very easy to assemble and sturdy.
