The zBoard Storage cabinets were VERY simple and easy to put together. The instructions were clear, to the point and had helpful diagrams to help me along. It didn't take long and all the storage cubes were put together and ready to go...and I must say that I was even able to complete the job with 4 of my children present and wanting to help! By the time I was putting together the last one, my 8 year old son knew exactly what to do and was basically able to do it himself...that's proof of how simple these are to assemble. I love it!
