Why a drink can tip in the stands
Seat movement and crowded space matter as much as the holder.
The base cannot stop the seating moving
Steadi widens a compatible drink’s support footprint. It does not lock a folding seat open or prevent another spectator from moving the bench. A stationary broad resting surface is the starting condition, not an outcome the holder creates.
Leave a clear path
A drink near feet, a bag strap or an aisle can be struck regardless of its base. Reposition it when the row fills up. Where no suitable surface remains, use an appropriate attached holder or hold the drink rather than making space by overhanging the base.
Recheck the drink you buy
Concession cups can differ from the bottle you brought. Measure the actual base and check full seating; diameter needs to be 2–3.15 inches. Steadi adds no lid seal. An open cup can still splash, so a wider base should not be described as spillproof.
