The cats love it. I have two decent sized cats (13 and 14 lbs) and this seems quite sturdy. I've had it for over a month and it is only against one wall, not in a corner. One of them loves the ball and plays with it every day. They fight over the top perch. the color is good. Wasn't sure if it was going to be in a room with grey or navy blue. This is a darker grey with some blue in it so it will work for either. The color is a little more modern looking than many cat trees.
