Well packaged and easy to build. The cat condos are a good size and the overall height is great for active cats.

Use the numbered F81 manual and the assembly video on this page. Hardware and an Allen wrench are in the box; you do not need your own tools. A step ladder helps on a tall tree. Follow the numbered steps, then finish the final tightening only after every floor-contact point sits flat. See assembly
When a matching part exists, replace the worn post or hammock without discarding the tree. Contact Support with your order number and the part you need.
