Every question, answered.

Yes — that's specifically the ground this is designed around. A narrow base tips on grass because it's standing on blades and thatch over soil that's already tilted for drainage; the wide flexible footprint spreads the load instead of balancing on one point, and the fins keep the cup from sliding loose when a chair leg shifts or a ball rolls through. Bump it and it comes back level instead of going over.

Turf can't be staked into the way grass sometimes tempts you to try, and it does run noticeably hotter than grass by an afternoon game. This doesn't stake into anything — the wide base just sits on top, so nothing needs driving into hot rubber infill, and it works the same way it does on grass or any hard, flat surface.

Yes — the 40 oz Quencher-style tumbler is exactly the cup that struggles most in a chair's mesh sleeve, and the one this handles best. The fit rule cares about the base, not the rim: 2 to 3 inches across settles in, and a 40 oz Stanley's base sits right in that window.

No — it doesn't clamp to an armrest or depend on matching a specific chair's tube. It sits on the ground beside the chair, on the bleacher plank, or on the wagon table, so it isn't limited to whichever chair happens to have a holder that fits.

Getting up is exactly when a chair's own mesh holder tends to fail — testing has found some won't keep a drink upright once the sitter's weight leaves the seat. This one holds its footing on its own base on the ground, so a rocking, empty chair next to it doesn't change anything. A stray ball or a direct kick is still a direct kick, but ordinary jostling is exactly what the wide base and the fin grip are built to shrug off.

Not on the bleachers themselves — the standard aluminum plank has no cup holder built in anywhere, and a bottle set on the ten-inch board rolls with the first crowd stomp. Set the base on the plank or the ground beside it instead, and the drink has a wide, gripped spot rather than a narrow rolling one.

No — that's the honest exception here too. The cup's base would be wide enough on its own, but the handle occupies the exact space a fin needs to close, which is also why handled mugs don't work in a chair's mesh holder either.

It's dishwasher-safe, or just rinse it under the tap. There's only one piece of flexible material and no seams or removable parts, so there's nowhere for turf crumb rubber or infield dirt to hide.

It's called the Steadi — molded in small runs in Orange, California by Steadi Labs, veteran-founded and patent pending. Every order ships free from steadilabs.com, with 30 days to send it back if it's not for you.

It fits, and comfortably so — a standard 12 oz can runs about 2.6 inches across the base, the industry-standard size used by nearly every U.S. beverage brand, which sits well inside the 2 to 3 inch window this settles in around. The same is true of a can in a koozie. The fins were built around the base range, not around one particular size of cup.

No, because the fit only cares about the bottom, not the rim. A tapered paper cup's base is what sits in the fins, and most drive-thru cups fall inside the 2 to 3 inch range there even though the cup looks much wider up top. The sticky-note test is built around exactly this — stand the cup on a 3-inch square and look at the base, not the rim.

Yes — the fins grip the outside of the base, not the temperature. An insulated tumbler barely sweats on the outside to begin with, and a paper coffee cup's base is dry cardboard either way, so neither one changes how the fins close around it.

It's one piece of flexible material with no spring-loaded parts, no clamp, and no rigid stake — nothing built to catch a hand or a bare foot. That said, a direct hit from a running kid or a stray ball is still a direct hit; the base is built to shrug off ordinary jostling — a chair leg shifting, a gust, a bump — not to survive being kicked outright.

Either works. It isn't clamped to a specific chair or armrest, so it moves as easily as picking it up and setting it down somewhere else — but because it isn't tied to one chair, plenty of families find it's simpler to keep one with each chair than to hunt for it mid-game.

Those only work where a spike can actually be driven into soil, which rules out turf, bleachers, and any paved lot outright, and even on grass, most roundups of stake-style holders still list wind and uneven ground as the weak point. This doesn't stake into anything — it's a wide base that sits on top, so it works the same way on grass, turf, a bleacher plank, or the wagon table.

That holder is fine while the wagon is parked at the pop-up, but it's a shallow mesh sleeve, and review coverage of these wagons describes it jostling drinks loose the moment the wagon rolls over grass. The drink still needs somewhere to actually sit once you're set up and the game starts — the ground beside the chair, the bleacher plank, or the wagon table itself all work the same way once the base is set on them.

It's a reasonable one for anyone who sits through games — nothing to assemble, one flexible piece that packs flat in a chair bag, and colors that read as sideline-appropriate rather than generic, like Touchline Grass or Home Team Red. It ships free either way.

There's less to wear out than with a clamp or a stake, since those depend on moving parts — a spring, a hinge, a mechanism to open and close. This is one piece of injection-molded material with no seams or hardware, so there isn't a mechanism to loosen or a spring to fatigue over a season of Saturdays.
