Will your coffee cup fit? A sticky note answers it — the test is below ↓
It's happened to you
These aren't rare mornings. They're most of them.
The first cup goes down next to the keyboard because there's nowhere else on the desk — the same setup behind every "coffee just hit my laptop" story anyone in tech support has heard.
The cup rocks in a cupholder that was never sized for it, and the first hard brake sends the last inch toward the gearshift well.
A half-asleep hand finds the cup's handle before it finds the phone, and the last sip goes toward the carpet instead of a mouth.
The folding table finishes settling into its lean about the same time the enamelware cup does, and neither one stays where it was set down.
Set down for five minutes on a rail built to shed rain, not hold a cup — and it's sliding before anyone's back for it.
Instant answer
You already own the fit test.
lands in here
A square sticky note: 3 inches, exactly — the ceiling of what fits, cup or tumbler alike.
A standard sticky note is exactly 3 inches on a side — a fact about sticky notes, not about this product, and it happens to sit right at the ceiling of what fits.
Camp cup, travel tumbler, the paper cup from this morning's drive-through: look at the bottom, not the rim. A cup tapers and a lid flares; the base is the only number that matters.
Base sits inside the square? It fits. Hangs over the edge? Too wide. A small circle lost in the middle, under 2 inches? Too narrow.
No ruler, no spec sheet, no guessing at the dealership or the campsite — one sticky note, one glance, with whatever's actually in your hand.
Fit check
The bottom inch decides what gets to land.
One line covers it: a base 2 to 3 inches across settles in and stays there. Everything below follows from that single measurement.
- Stanley 40 oz H2.0 FlowState Quencher fits
- Insulated travel tumbler, 20-30 oz fits
- Disposable to-go cup, sleeved fits
- Keep cup, screw-lid fits
- Enamelware camp cup, handle-less fits
- Cold brew mason jar fits
- Ceramic desk mug, handled handle in the way
- Single-serve pod-brewer mug, handled handle in the way
- Moka pot demitasse cup too narrow
- Cortado glass too narrow
There's a floor as well as a ceiling — under 2 inches, the base sits too loose and rattles instead of gripping. The handled mug is the one honest exception on this list: the base itself would fit, but the handle sits where a fin needs to close.

The value
Three reasons it moves with the coffee.
Holds on wherever the surface changes
The wide base and flexible fins resist tipping through a hard brake, a knee bump at the desk, or a folding table finishing its lean — it's not tuned for one surface, it's the same grip wherever the base lands.
Holds what actually leaves the kitchen
Tumblers, to-go cups, and handle-less camp cups drop in and get gripped by the bottom inch. A handled mug is the one honest exception — the handle lands exactly where a fin needs to close, so it doesn't seat the way the rest of the lineup does.
Looks like it belongs on a desk, not bolted to one
One piece of matte flexible material, no clamps and no plastic hardware. It sits on the desk, the console, or the picnic table without announcing itself, and it packs flat enough to ride along to wherever the next cup happens.

Real reviews of the Steadi — these ones mention coffee life.
Sits right next to me on the couch, and now my coffee doesn’t spill
Linda B. · 2026-07-18Love my Steadis! This is one of those products that you don’t know you’re missing in your life until you use it. I’ve been using these to stabilize our drinks on the couch. This way I can put it right by me rather than a few feet away on the coffee table. It’s like a cupholder that goes with your drink. Highly recommen

Why more than one
Two identical travel mugs. Whose is whose?
Two people in the same house, same brand of travel tumbler, same shelf by the coffee maker — grab either one and there's no way to tell whose coffee is whose until the first sip gives it away. It happens before either cup even leaves the kitchen, let alone makes it to a desk or a car console.
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.
Function
Built for whichever surface it lands on.
A desk is flat but crowded, a car console is hard but moving, a campsite is neither — the wide, low base doesn't need one specific surface. It spreads across whatever's there instead of needing that surface to be level.
Flexible fins hold the cup by its bottom inch, so it can't slide off a rail, roll loose in a cupholder, or walk across a desk on its own.
A hard brake, a knee under the desk, a table finishing its lean — the base's low, wide weight rocks with the motion and brings the cup back level instead of letting the tip continue.
Other routes
What already exists, and the moment none of it covers.
| A self-gripping 'no-tip' cup | The Coffee Cup Holder | |
|---|---|---|
| Setting it down without checking | Only works if the surface checks out first | No checking needed — it settles on its own |
| The car dashboard or console | Ruled out by the maker's own listing | Holds steady through a hard brake or turn |
| Outdoors — the campsite, the porch rail | Where the maker says this grip runs out | Settles in on a table, a rail, or dirt |
| A clean glass or laminate desk | Works fine there — flat, non-porous is the design | Same base, same grip, sits there too |
| Whatever cup's already in your hand | Its own cup, not the one you already own | Holds the cup you already reach for |
| Cost | A whole new cup to switch to | One small base, keep the cup you have |
Only works where there's a graspable edge to clamp onto — typical models need a desktop between about half an inch and two and a half inches thick, and top out around 3.6 inches of cup diameter. Fine for one desk, and left behind the moment coffee leaves the room.
Its grip technology only engages on a flat, non-porous surface — glass, metal, marble, finished wood — and the maker's own listing rules out car dashboards, textured surfaces, and tablecloths. It solves tipping exactly where tipping was already unlikely, and gives up everywhere coffee actually gets set down outside a desk.
Keeps an open cup level while it's moving from one room to another — a real problem, just not this one. The moment the cup gets set down on a console or a folding table, the tray's job is already finished.
Dome lids and tighter lid tolerances cut down on sloshing while a cup's in hand or in motion — industry reporting notes a lid oversized by just over a millimeter and a half can meaningfully raise leak rates. None of it changes what happens once the cup is set down: a tapered paper cup is exactly as tippy on a car console with a well-fitted lid as with a loose one.

Before you buy
Asked between the first cup and the third.
Is it actually safe to use next to a laptop?
That's the scenario it's built around. The wide base keeps the cup from tipping toward the keyboard in the first place, so it holds steady in the exact spot most likely to end in a support-forum thread about drying out a laptop.
Will it actually hold on in the car?
Yes — hard, moving surfaces are within what it's built for. The wide base and the fins keep a cup from rocking loose with a hard brake or a turn, which is exactly where a factory cupholder sized for a can tends to let a cup down.
Does it work on the nightstand?
Yes — it holds steady on hard, flat surfaces at least as well as anywhere else, and a cluttered nightstand is exactly where that matters. It also frees up room for the water glass and the phone charger fighting over the same few inches.
What about camping — folding tables, coolers, the ground?
That's the terrain it was designed to handle. The base doesn't need a level surface to work from; it sits low and wide on whatever's underneath — a wobbling folding table, a cooler lid, bare dirt — so a wobble rocks it instead of tipping it.
Will my cup or tumbler actually fit?
Measure the bottom, not the rim. A base 2 to 3 inches across settles in — the 40 oz Stanley does. Handled mugs don't: the handle lands exactly where a fin needs to close, so it's built for tumblers, to-go cups, and handle-less camp cups instead.
I already have a self-gripping 'no-tip' cup. Why would I need this?
Those grips work on a flat, non-porous surface and stop working on a textured or angled one — car dashboards and popcorn-textured surfaces are explicitly where the leading version says, by its own product description, that its grip fails. This isn't limited to one kind of surface, so it covers the car and the outdoors, exactly where that kind of grip runs out.
Does anything clamp to the desk or the car?
No. Nothing clamps to a desk edge, wedges into a console, or attaches to anything. It sits on top of whatever surface is there and moves with you when you get up.
How do I clean it?
Rinse it, wipe it down, or put it in the dishwasher. It's one piece of flexible material with no parts to come apart or trap old coffee.
Does a handled mug work at all, or does the handle get in the way?
Not well, and it's worth saying plainly: the base would fit most handled mugs, but the handle sits exactly where a fin needs to close around the cup. It's built for tumblers, to-go cups, and handle-less mugs instead.
Who makes it, and where do I buy one?
It's called the Steadi, molded in small runs in Orange, California by Steadi Labs. Every order ships free from steadilabs.com, with 90 days to change your mind.
From
Molded a short drive from your first cup.
The maker is Steadi Labs, a small veteran-founded company in Orange, California. It's injection molded in small runs — never by hand — and none of it travels far: the mold, the material, and the color runs all sit within about three and a half miles of the shop. The people who make it read hello@steadilabs.com themselves, probably over their own first cup of the day.
