Finally, somewhere to put your drink — any can, anywhere you land.
4.9 from 119 Steadi reviewsOne base grips the standard can, the tallboy, and the slim seltzer can — same base, three different widths. No table needed, and no lid to catch a mistake if it goes over.

Will your can fit — standard, tallboy, or slim? A sticky note answers it ↓
The situation
Every holder out there was built for one can. You don't drink one can.
"A can" sounds like one shape, but it isn't — a standard soda or beer, a 16 oz tallboy, and a slim hard-seltzer or energy-drink can are three different widths, and not one of them comes with a lid. A holder cut for one fails the other two, and every failure is a full loss, not a spill.
A standard can runs about 2.6 to 2.7 inches across. A slim seltzer or energy-drink can — White Claw, Truly, Red Bull, Celsius — runs closer to 2.1 to 2.25. Same cooler, two different diameters, and most holders were only ever cut for the wider one.
Some folding and camp chairs skip the cup holder entirely; the ones that have it sew a mesh pocket to one width. Load it with a tallboy and the extra height leans out past the armrest. Load it with a slim can and it rattles loose.
Cup holders didn't show up standard in cars until 1984. Nobody's gotten around to the lawn, the dock, the garage floor, or the tailgate lip since — those surfaces were never designed to hold anything upright, can or otherwise.
No straw lid, no twist cap, no gasket to fail slowly — a can that goes over doesn't leak, it empties. Whatever tips it, the drink is finished before anyone reaches for a towel.
None of that is dramatic. It's just a lidless object, in a size that keeps changing, set down on a surface that was never built for it — over and over, at every place a can turns up.
Sound familiar
You've set a can down in every one of these spots.
Cans line up along the tailgate lip and the cooler lid while everyone stands around the grill. The liner's sloped to shed rain and humming faintly off the idling engine next to it — someone's elbow finds one before the first quarter starts.
A can goes down next to the camp chair leg in the dark. Someone stands up for more firewood, catches it with a boot on the way, and it's gone before anyone even hears it hit the dirt.
The can gets set on the grass at the end of a pass — flat enough, until the mower turns and the ground turns out to be a slope. It's found again on the next lap, empty and on its side.
The can sits at the edge of the workbench, past the sockets and the parts tray, because there's nowhere else for it. An elbow reaching for a wrench finds it instead, and it lands on the concrete before anyone looks up.
The one built-in cup holder is already taken. Every other can on board sits loose on the gunwale or the cockpit floor, and the next wake decides which ones make it back to shore.
The desk-drawer test
One sticky note answers it before the cooler's even packed.
lands in here
A square sticky note: 3 inches, exactly — the ceiling every can in the cooler falls under.
The standard square is exactly 3 inches on a side. That's a fact about sticky notes, and it happens to land right at the ceiling of what fits.
Standard, tallboy, or the narrower slim and sleek cans from the cooler — set whichever one's actually in your hand on the square and look at the base, not the label.
Base sits inside the square with room around it? It fits. Hangs off the edge? Too wide. Lost in the middle with most of the paper still showing? Too narrow.
Skip the guessing before the cooler gets loaded — one sticky note settles it for every can you're likely to bring.
Sizing it up
The bottom inch decides what stays standing.
The spec is one line: a base 2 to 3 inches across settles in — floor and ceiling both. Every can format that shows up in a normal cooler falls inside that range; here's how each one, and its usual tailgate neighbors, actually lands.
- Standard 12 oz can (soda, most domestic beer) fits
- 16 oz tallboy / pounder can fits
- Slim hard-seltzer can (White Claw, Truly) fits
- Sleek energy-drink can (Red Bull, Celsius) fits
- 40 oz Stanley-style tumbler fits
- Can inside a koozie sleeve tighter with the sleeve on
- 12 oz glass longneck bottle fits
- Handled camp mug handle in the way
- Insulated handled travel mug handle in the way
There's a floor as well as a ceiling — under 2 inches, a base doesn't get gripped, it gets lost in the middle. Handled mugs are the one honest exception on this list: the base often fits, but the handle sits exactly where a fin needs to close.

The alternatives
Compared to what's already in the cooler bag.
| A koozie | The Can Cup Holder | |
|---|---|---|
| Standard, tallboy, or a slim seltzer can | One sleeve size, not built for all three | Fins flex for whichever one's in your hand |
| On grass, sand, or a truck liner | Grips the can, not what it's sitting on | Wide, low base — settles in |
| A wake, an elbow, or a boot | Same small footprint, same tip | Rocks and settles, resists tipping |
| Keeping the can cold | Built for exactly this, insulates well | Not insulated — a different job |
| A bottle or a 40 oz tumbler | Cut for a can, nothing wider | Same base holds a bottle or tumbler too |
| Moves from the tailgate to the boat | Still sized to whichever can's inside it | One base, grips whatever shows up next |
| Cost | Cheap, and most people already own one | One small piece, handles the other job |
Koozies — also coozies, huggies, stubby holders — are so common the name genericized right off its own trademark. Their real job, by their own advocates' account, is blocking condensation more than insulating, and nothing about foam or neoprene stops a can from tipping. A slim can and a standard can need different-sized sleeves too, so the one in the glovebox doesn't cover both.
A steel or plastic spike topped with a can cradle, built for lawns, campsites, and beaches — which means it's stake-dependent by design and does nothing on a tailgate bed, a boat gunwale, a dock, or a concrete garage floor.
Drilled into a boat, a golf cart, or a chair arm at one fixed diameter. It solves exactly one can format in exactly one spot and leaves every other can size, and every other surface nearby, exactly where it was.
Built around the standard ~2.6-inch can. Slide in a narrower slim or sleek can and it rattles loose in the same slot that held the last one fine; nothing wider than a can fits at all.
Why more than one
Two identical cans. Whose is whose?
Grab one out of a shared cooler at the tailgate and it looks exactly like the other twenty in there — same size, same sweat running down the side, no name on it anywhere. Somebody's already taken a pull from the wrong one before anyone notices. A color-coded base means you know which one's yours without asking.
Build your set
Give everyone their own.
Pick a pack, then give each one a color — so nobody has to ask which drink is theirs.
From the reviews
What buyers say.
Real reviews of the Steadi — these ones mention can life.
I have a tendency to spill my drinks and have two cats. This is one of the best things I’ve ever impulse bought. It works. It actually works. It’s a heavy, wide enough base that it is actually stable. My “spot” in the living room is near a somewhat-cushioned fabric ottoman, which is where I usually put my drinks. It’s
Dixie · 2026-08-30I love my Steadi can holder. I use an ottoman beside my couch for drinks and remotes. This keeps a can steady and allows me to have a can of soda or water nearby. Im disabled and its hard to get up repeatedly for a drink!
Kathi D. · 2026-08-20I really love these! I can leave my drinks on the couch cushion next to me and not worry about them spilling. I like to sit in the corner seat of my sectional, so there’s no table on either side of me. These are the perfect solution without having to get up every time I want to take a sip.
Andrea C. · 2026-08-18Genius! Finally I can sit in a corner of the couch and have my drink next to me. Works beautifully, sturdy and stable. I'm very happy I found this item.
jlhinckley · 2026-07-28Really does keep your drink cans and bottles from tipping over! We are quite impressed with these!
SPK · 2026-07-25This is a great product. Does exactly as it is advertised. No more turned over water containers due to my nosey cats. My granddaughter can reach it but she can't tip it over. 😁😁

Fair questions
You're probably thinking…
It's one molded piece — no spring, no hinge, no clip to snap. Nothing mechanical inside it to fail. Molded in small batches in Orange, California, with 90 days to send it back if it doesn't hold up.
The fins flex across the 2 to 3 inch range, so the same base grips a standard 12 oz, a 16 oz tallboy, and a narrower slim seltzer or energy can. One base in the cooler bag instead of guessing which can it's for.
A koozie keeps it cold — it doesn't stop it tipping. Different job entirely. Most people run both: koozie for the sweat, this underneath it for the tip.
It's less than the six-pack that just went over in the grass. The multipacks bring it under ten bucks a unit for the whole crew's chairs.
It resists tipping through exactly that — a tail, a boot, a wake, an elbow — and settles back down. A hard direct kick still wins, same as anything sitting loose, and that's said plainly instead of pretending otherwise.
The practicalities
Asked at the tailgate, answered here.
Does it work for a 16 oz tallboy, not just a regular can?
Yes — a tallboy shares the same base width as a standard can, just with more height riding on top. The fins grip the bottom inch the same either way, so the extra height doesn't change what's holding it up.
What about slim cans — the seltzer and energy-drink ones?
Those run narrower than a standard can, closer to 2 to 2.25 inches, and they still settle in. The fit spec is 2 to 3 inches across, and a slim or sleek can sits comfortably inside that range.
Does a koozie mess with the fit?
It can — a sleeve adds bulk the bare can doesn't have, so the fit gets tighter with it on. If it feels snug, pull the sleeve off; the base grips the bare can fine either way.
Does it actually work on grass or sand, or just tables?
That's the point of the wide base — it spreads the can's weight instead of letting a narrow footprint sink in or lean over, on turf, on sand, on a boat gunwale, or on a concrete floor alike.
Do I need to drill it into the boat or stake it into the ground?
No. Nothing drills, stakes, or clips to anything. It sits on top of whatever surface is in front of it and moves to the next one in a second.
Do handled mugs fit?
No — that's the one honest exception on the fit list. The base fits, but a mug with a handle doesn't seat, because the handle lands exactly where a fin needs to close. Handle-less mugs and camp cups within the base range are fine.
Does it hold up on a moving boat or a bumpy tailgate?
Movement is the actual design brief. The low, wide base rocks with a wake or a vibrating liner and settles the can back level. It resists tipping — a direct hard kick still wins, same as anything sitting loose — but the ordinary bumps of a day outside are exactly what it's built to shrug off.
How do I clean it?
Rinse it, wipe it down, or put it in the dishwasher. It's one piece of flexible material with nothing to unclip or take apart.
Who makes it, and where do I buy one?

The people behind it
Molded closer than the tailgate lot itself.
The maker is Steadi Labs, a small veteran-founded company in Orange, California. It's injection molded in small runs, and nothing about it travels far — the mold, the material, and the color runs all sit within about three and a half miles of the shop, closer than some drives to the boat ramp. The people who make it read hello@steadilabs.com themselves, usually before the next batch goes in the mold.
Keep the can standing, wherever it ends up.
The tailgate, the lawn, the boat, the workbench — the can settles in, not over, and nothing about the surface underneath decides whether it makes it back to your hand.
