Well made ....Very sturdy .... Easy to assemble .... 
(about 30 minutes) using the Alan wrench included in box 

and we both love the sisal rope legs for her to use as scratching posts..

Even through I feel it's about $20 over priced, I highly recommend  this cat tree...
 
Notes: 

#1. the "Tepee" is worthless as it is too small for any adult size cat. I suggest not putting in on the tree.

#2. the only thing the "hammock" is good for is storing her toys ... (which she immediately throws out on the floor again..grrrrrrrrr)..
 
Terd supervised the assembly and immediately climbed all over it before climbing to the top shelf and going to sleep..
She loves it and so do I..
