I always thought I was assembly challenged but I was able to put this together with the Allen wrench provided even though the instructions recommend 2-3 people. From my photo you can see my sweet cat loves it. She had fun playing with the fluffy ball and slept on the top part the first night. She even scratched her nails on the posts. Overall it has a small footprint and doesn't overpower my small space. If you are considering this cat tower, don't hesitate.
