This cat tree is so cute!! It is a lot sturdier than I expected and husband who is NOT mechanically inclined was able to put it together with no problem.  The "kids" love it and 6 our of the 7 were sitting on it right away so it is able to support them.  We have it outside in their enclosure so the nylon/plastic is perfect for weather.  Fast shipping and a great price too! Thank you Wayfair! Now I am going to shop for modules to add to this!
