These raised beds are fabulous!!! Assembly can take a bit of time because there are a lot of nuts and bolts. But they are easy to do. The smallest ones took me about an hour each to do. The largest one I bought was a "U" shaped one standard size and it took 3 1/2 hours. I assembled these by myself. They seem sturdy and durable. I plan to get more next year. I'm hoping that they work the way I want for growing my veggies
