A few years ago, we saw the below article in Cottage Living (Jan/Feb. 2006 issue) about how to make a hinged potting bench.
We made ours out of cedar and used rope instead of chain link. It's so great to have a place to make such a mess and not wreck the patio table (like I was doing before). You can see a bit of the bench in the down position in this post.
It is definitely used and abused ... I mean well loved.
