I don't know how the people behind you are gonna feel about the reclining part of Ventura's Stadium Seats, but if the chair's thousand+ reviews are to be believed, you'll sure love it.
A wide seat and backrest that reclines to 6 different positions cover the Ventura Seat's steel frame. They, along with the armrests, are cushioned with high density foam for additional comfort during overtime. Chairs also have a reinforced underside that's water-resistant when game day coincides with rain day.
In addition to slipping a Ventura Stadium Seat into your allotted square of bleacher space, the chairs work great at the beach, concerts, and as additional seating in game and dorm rooms. When you're outside and ready to pack up, they fold to 2" flat and have adjustable backpack shoulder straps for toting back home.
