Love it!!! 
Husband put it together by himself and said there was enough piece and extra hardware in the package. 
I laid down chicken wire then professional fabric then inside each container cardboard then between three containers  Total of 42 cu ft of garden soil and 9 cu ft of manure. Initially it was wobbly but once the soil was filled it was very sturdy and set in place. 
Amazing purchase. 
Recommend without any hesitation.
