Negatives:  There were no assembly instructions included.  The corner posts came in two separate lengths and are supposed to be stackable but there is no connector to hold them together other than with gravity.  (I bought the 17 1/2 inch depth.)  The screws to attach the caps  are not pre-drilled.  It would be MUCH better if there were a single longer corner piece when ordering the deeper bed.
Positives:  If you alternate the corner pieces, i.e., longer on the bottom shorter on the top then shorter on the bottom and longer on the top, when the boards are inserted and the bed assembled it holds together much better than if you do them all the same way.  There is just a half inch or so of board in the lower portion of the corner support to hold the two uprights together.  There was very little warpage and nothing that would impact function and when finished it looks good.  Like the smell of the cedar.
Price is right for what seems to be a solid deep garden bed.
