Why drinks tip on bleachers—and what to check
Separate container fit, base support and surrounding movement before choosing a fix.

The container does not seat fully
An oversized bottom, low handle or added boot can keep a container from seating as intended. Check the measured base against 2–3.15 inches and look at how the holder meets the container. Do not force the pairing or infer fit from the brand name.
The base is partly unsupported
A narrow bench, seam, cushion or sloped section may leave part of the flared base without useful support. Move to an appropriate level supported spot. A wider footprint helps only when there is a surface for that footprint; it cannot fill an open gap.
Someone bumps or moves the setup
Steadi is freestanding. It does not restrain a drink against a kick, crowd movement or bleacher vibration. Create more clearance, keep the drink under your control, or use a suitable permitted mounted holder. Do not treat an illustration as a stability test.
The drink spills without the holder tipping
Liquid can splash out of an open container independently of the holder. Steadi is not a lid or seal. A compatible lid may address splashing, but follow that drinkware maker’s guidance and do not assume every lid is leakproof.
Identify what needs changing
Send support the exact drink model and a photo of the pairing if fit is unclear. For a seating-space problem, review the placement guide. For absent space or an unsuitable attachment, compare different holder categories rather than expecting one accessory to solve every setting.
