So far I only put together one of the raised garden beds and it is massive! It took me a little over an hour to assemble one. It was quite the task, time consuming, but not that difficult. I would recommend a wrench to hold the nuts in place and tighten the screws simultaneously. I plan on making the second raised garden bed a bit smaller, making it about a 4 foot by 4 foot bed which you can do, but you'll have leftover panels. Once everything is tightened this seems like a quality and sturdy piece. There are metal support beams in the middle making it even more sturdy. I assembled in my garage and carried it by myself to the back yard. It'll take a lot of soil to fill up! I'd order it again. Lots of screws!
