Here
is a picture of some shelves I made. I used two horizontal stackers and
put them together so it could collapse. I put hinges on the inside of the
uprights and top shelf so the legs just fold in upon itself when taken
down. I used eye hooks to hold the back in to give the shelves some
stability.
As you can
see we store all kinds of thing here while we are camping and it fits perfectly
over the microwave.
And this is
what it looks like for storage. It all folds down and sits beside our cushions
under the table for travel.
