I also have a Coleman camp chair in there (it has a side table that pops up).
So I can sit with a cup of coffee, and rummage my books, binders and magazines in peace!
It's not gorgeous, but it folds up, AND it is really comfortable. It supports my back just right! I got mine at Fred Meyer when they run their camping equipment sales! But it is also for sale
Mine is tan canvas, not gray.
