These arrived well packaged, all pieces were present, and they included a parts list/assembly instruction sheet (although, they would be easy to figure out without an instruction sheet). Each planter box only took about 5 minutes to assemble and once assembled, they are rather sturdy. That being said, I cannot imagine it would be smart to assume you could move one of them all about once you have added soil and plants, unless you are supporting the planter from under the base rather than carrying it by the sides. They seem to be a good height (with the legs on) to make them comfortable to work with when kneeling without straining your back.
