After much shopping around we decided to get this for our two adolescent cats, and it was such a huge hit!  They practically live in this tree and love to climb all over it. The basket at the top took some getting used to, and they still don't really want to try the hammock yet, but I do not regret this purchase one bit! 

The materials are good quality. The sisal rope is such a high quality that even as I write this, ( a few months after purchasing it.) There is barely any signs of fraying at all. And I have one mighty little scratcher in the house. The other thing I really like and haven't really noticed anyone mentioning is that the blue-ish fabric is actually fantastically easy to clean! You can wipe against the fabric with a damp cloth and all the cat hair comes right up. So much better than the basic carpeted trees!
