Query: Disappointing Stadium Seat

We were disappointed in the stadium seats. They provided no back support, even though there is a "back" to the chair. The seat portion is too deep to fit on the bench seats of the grand stands, so it was difficult to keep it centered so that it would not collapse or fall when we leaned forward or backward. All-in-all, I found it to be a bit better than sitting directly on the grand stand bench seat, not nearly as nice as the old-fashioned stadium seats with a shallow seat portion and true back support, and about equal to sitting on a cusion seat with no back attached.On the positive side, they were easy to carry back and forth to the game; and, when folded closed, formed a little pocket in which to carry our other game gear. They were also less expensive than traditional stadium seats.
