I spent some time reviewing different cat trees on several sites. I choose this one from Armarkat do to the positive reviews it got, and im happy to say I was not disappointed.  my cat was playing on it as I was putting it together, he is a large cat and has played with every feature within 5 minutes of it being up and I have to say it didn't move at all.  I also have to give wayfair 5 stars for their service, I almost purchased this item from another company but the shipping charge was outrageous, after shopping around I found wayfairs site with free shipping and 2 day delivery I ordered right away, to my surprise it was here the next day. so I have to say I am very happy and so is my kitty. thank you wayfair!
