Choosing a drink holder for stadium seating
Match the holder to a fixed bench, portable seat or built-in ring.

A seat attachment needs a real attachment point
A clip, bracket or strap holder must match the seat it is designed for. Check the seat maker’s instructions and venue restrictions. Steadi has no attachment hardware, so it cannot replace a bracket on a folding seat or hang from a narrow armrest.
A built-in ring is its own system
A ring may support a tapered cup differently from a straight bottle. Use it according to the seating instructions and try the actual drink. Steadi’s 5.2-inch base is a resting footprint, not an adapter diameter. Do not balance it across the opening or force it into a ring.
A fixed bench can offer a resting spot
Only consider a broad level section that fully supports the base and leaves other spectators and the aisle clear. If the stands are crowded or the spot is likely to be kicked, keep the drink in the intended holder or choose another location. An available seat does not automatically create safe spare space.
