Husband made it seem easy to put together, little over whelming for me but it had all the parts which is really important. We added additional zip ties that were a bit stronger at all the joints to create a very strong structure. The hammocks are not real good but best if you add some of there own items. Our cats haven't yet really taken to it yet, will take some time and added decor so they don't feel like they are being "caged" up.

1. Cheaply made with critical parts made of plastic which break very easily during assembly. 2. Poorly written instructions. Did not translate to English well. Some instructions missing. Pictures very difficult to understand. 3. When box delivered, had measurements of the box and the model of the box written on the outside of the box. No mention of what was actually in the box. Therefore had to open it. 4. Customers service was very responsive. 5. The cage was the only one that I could find that would do what I needed it to do.
