I bought this tree for my three month old kitten and I'm so glad I did! My boyfriend set it up for me in a half hour, which surprised me because we set aside an entire evening to do it together after hearing what a hassle these things can be to put together! I have it placed in a corner of the room to give it some extra stability, but it really doesn't need it. Everything seems to be holding up well and he absolutely loves the little house to hide all his toys in! 

The only weird thing about it is that the flat top of each bolt is exposed (you know, the part that you put the wrench to); sometimes right in the middle of the platform! I've never seen anything like it, but it really doesnt detract from its overall visual appeal and usage. My kitten hasnt given them a second glance so I've ignored it. 

I've been impressed with it and you certainly can't beat the price!
