I was at a football game the other day and I saw the coolest thing.  It looked like a lawn chair but it didn’t have any legs and it was attached to the bleacher bench.  It was great!  The entire outfit folded up to the size of a small briefcase.  When the guy who brought it walked in, he simply carried it in, unfolded it, and hooked it onto the bleachers.  It had a couple of hooks that latched it to the bench.   The back folded up and locked into the upright position.  It had a couple of straps to adjust the back to the exact position that you are most comfortable in.  It had a couple of arm rests and there was a cup holder in each one.  It even had several pockets and pouches.  I can’t wait to buy a couple of these bleacher chairs.
