Will the glass on your coffee table fit? A sticky note answers it — the test is below ↓

What's really going on
Five places to put a drink, and you know the catch in every one.
Where the drink goes gets settled fresh each time you sit down — the couch keeps offering the same five spots, and you've learned what each one costs.
The classic gamble. Rolled arms are crowned, track arms are padded, leather adds slick to the tilt — there is no level plane up there, only upholstery that dips the moment an elbow leans anywhere near it.
The official drink surface, moved out of range by the furniture itself. Deep modern seats put the table more than an arm's length from a reclined body, so the drink you responsibly parked there costs a full lean per sip.
A foam block that tilts each time anyone sits, stands, or shifts — and that migrates on its own; keeping couch cushions from sliding is a whole genre of advice. A glass standing there is standing on moving ground.
The wedge spot between cushions, where remotes and sippy cups go to disappear. Foam is the only thing gripping whatever's parked in it, and foam gives — precisely when someone sits down or gets up.
Below your sightline, beside the chaise, directly in the path of stray feet and a dog's tail. Out of the way right up until it isn't.
No one of these is a crisis — which is exactly why it never got fixed. It's a small toll on every evening, and you've paid it long enough to stop counting.
Scenes you'll recognize
You've sat through every one of these.
You've achieved the position — blanket arranged, dog across your legs, remote located — and your seltzer is still out on the coffee table. Reaching it means dismantling everything you just built, so you stare at it instead.
The game's on and your glass is up on the arm, because the table's too far. Now you celebrate from the shoulders up — arms pinned, elbows frozen — because the arm dips whenever weight moves near it, and the glass knows.
Cartoons are on and someone small wants their cup on the cushions. The house rule exists because you know what juice does once it gets past the cover — so the cup stays in the kitchen, and the complaining stays on the couch.
The credits are still twenty minutes out, someone's asleep against your shoulder, and you've been holding your glass since the second act — because setting it down anywhere within reach means trusting the arm.
One-note test
The fit test has been on your fridge the whole time.
lands in here
A square sticky note: exactly 3 inches — same ceiling on the arm, the cushion, or the coffee table.
The standard square is exactly 3 inches on a side. That's a fact about sticky notes — and it happens to be the precise ceiling of what fits.
Use the one sitting on your coffee table right now, and judge the bottom, not the rim. Tumblers taper and glasses flare — the base is the only measurement that counts.
Base inside the square? It fits. Hanging over the edges? Too wide. A small puck adrift in the middle — under 2 inches? Too narrow.
No calipers, no spec chart, no guessing. One sticky note, one glance — with the glass that's been living dangerously on your armrest.
Fit, answered
The bottom inch decides, not the rim.
One rule decides all of it: a container base 2 to 3 inches across settles in. The verdicts below just follow the rule.
- Stanley 40 oz H2.0 FlowState Quencher fits
- Yeti Rambler 30 oz fits
- Pint glass fits
- Stemless wine glass fits
- Water glass fits
- Standard 12 oz can fits
- Slim seltzer can fits
- Beer bottle fits
- Lidded water bottle fits
- Kids' straw cup fits
- Coffee mug, handled handle in the way
- Espresso cup too narrow
The floor matters as much as the ceiling — under 2 inches, a base sits too loose. And the handled mug is the honest exception: its base fits, but the handle lands exactly where a fin needs to grip.

The short version
Three reasons it beats the lean.
Steady on the cushions
Soft, shifting ground is exactly what this was shaped for. The wide, low base spreads its footprint across the cushion instead of sinking a point into the foam — someone sits down, the seat re-tilts, and the base rocks with it while the drink settles back level.
Holds the cup you actually drink from
The pint glass, the can, the stemless wine glass — and the 40 oz tumbler that armrest holders turn away. Every one of them gets taken by its bottom inch, which is the only part the fins care about.
Made to be left out
Matte, flexible, and in colors that belong indoors — no clamp jaws on the arm, no bamboo tray, no gadget shine. It sits on the seat like it came with the throw pillows, and it moves to the chaise when you do.

Marsha B. · 2026-07-25I had to order these (in case I didn’t see them again.) I was hoping shipping wouldn’t take too long and it didn’t. We just love them. Our friends are visit and using them while sitting on the sofa with their beers. I can even fit my thinner koozie under mine, for my soda. Happy I purchased them. They’re also a convers
Customer · 2026-06-26Love my Steadi holders! I purchased two but plan to purchase more to give as gifts. Great customer service answering my questions and fast shipping.Where have these been all my life? No more spills on the sofa, trying to balance a drink or a bottle against the pillows. 100% satisfied customer. Great invention.
Catherine B. · 2026-06-19I LOVE my 2 steadis!!! I can now have my cold canned seltzers and sodas on my sofa, my bed, it’s fabulous. I’m considering buying more for when the grandkids are here. You just cannot knock your drink over. It’s fabulous!

Fair questions
You're probably thinking…
The CouchCoaster's weight anchors it to an arm that dips the moment someone leans in — the failure was never the coaster, it was the arm underneath it. This skips the arm entirely and sits on the cushion instead, so the surface that was moving isn't holding your drink anymore.
Plain, non-absolute language — resists tipping, never spill-proof — real reviews with specific detail, and a named small maker in Orange, California. That's the opposite of the faceless five-star wall that's usually the tell.
The 40 oz Stanley and the 30 oz Yeti Rambler both fit. Grab a sticky note — the standard square is exactly 3 inches — stand your cup's base on it, and you'll know in about ten seconds, no tape measure required.
It never touches the arm at all. It sits on the seat cushion, the chaise, or the coffee table, so arm shape doesn't matter — which is the real answer to a doubt you may not have known how to phrase yet.
Set next to a ruined cushion, or the CouchCoaster and clip-on tray already gathering dust in a drawer, this is the one still on the couch a month from now — and it starts at $14.95, free shipping either way.
Thirty days beside you, for real.
Keep it on the couch for a month. If it doesn't do what this page says — on the cushion, on the arm, wherever you actually sit — email hello@steadilabs.com and it gets made right. No forms, no fight.

Why more than one
Two identical Stanleys. Whose is whose?
You bought the same 40 oz tumbler your partner already owns, and movie night now starts with somebody squinting at two identical cups trying to remember whose had the extra ice. Setting them side by side on the table doesn't solve it — a color that's plainly yours does.

Instead of what you do now
Compared to the couch caddies you've already met.
| The weighted armrest coaster | The Sofa Cup Holder | |
|---|---|---|
| Fits the arm you have | Needs about 5.5 inches of relatively flat arm — rolled and curved arms may not qualify | Skips the arm — sits on the cushion instead |
| Holds the 40 oz tumbler | Caps out below the big tumblers — that class doesn't fit | The 40 oz Stanley fits |
| Stays put when you lean on it | Reported to tip once the padded arm dips under a leaning body | Rocks with the cushion, low and wide, and settles the drink back level |
| Moves with you around the couch | Anchored to one qualifying arm — relocating it means finding another | Cushion, chaise, ottoman, coffee table — goes wherever you sit |
| When the couch is full of guests | One per qualifying arm — nothing for the other seats | One per person — any cushion works, arm or not |
| On a genuinely flat table | Holds the cup snugly there — the reported tipping traces to the arm underneath, not the grip | Holds steady there too |
| Cost | A weighted gadget — another purchase to justify | One small piece, not another piece of furniture |
Fit is a lottery: the clamp needs a squared arm inside its stated range, and sofa arms refuse to standardize. Buyers with rolled arms report it simply won't mount, and buyers who get it on keep describing the same slow loosening into a wobble that needs constant re-seating.
It solves the fit problem by bending over any arm — and reviewers keep arriving at the same catch: a mat that conforms to a curve is a curved surface. One puts it flatly: less stable to set a cup on than the bare armrest underneath it.
The best-known one needs a wide, reasonably flat arm and caps out below the big tumblers people actually drink from — and its own reviewers warn it goes over when the padded arm dips under a leaning body. The weight anchors it to a surface that won't stay level.
Its anchor is the cushion itself, and cushions compress. The category's own listings concede that holders gripped only by foam shift when someone sits down or gets up — and that the middle of the seat, where you'd most want one, is the least steady spot to put one.
Know your upholstery
A sofa is soft everywhere you'd want to put a drink.
No one is being careless here. Upholstery is engineered to compress under a body, and everything resting on it moves when you do.
Rolled arms are domed, track arms are cushioned, and leather adds slickness on top of the tilt. Arm shapes vary so much that clip-on tray makers publish fit ranges wide enough to admit they can't count on anything. There's no level plane up there — just padding that dips under a leaning elbow.
Compresses inches under body weight and re-tilts each time anyone sits, stands, or reaches. Cushions also creep out of position under normal use — the surface a drink rests on is itself known to wander.
The compressible seam between cushions — the improvised wedge spot. Foam is the only thing gripping whatever's parked there, and foam gives right when a body lands on the cushion next to it.
Check the tag under your cushions: W means water-based cleaning is fine, S means solvent only, X means vacuum and hope. On solvent-only microfiber, plain water dries into a visible ring — a sweating glass leaves evidence, and erasing one ring means re-wetting the whole panel so it dries as one piece.
Open-cell foam takes a spill like a sponge and holds it. The standard rescue — towels stuffed between cover and foam, baking soda overnight, strictly no heat or the smell sets — tells you everything about what happens once milk gets past the zipper.

Straight answers
Asked mid-game, answered here.
Does it really work on a couch cushion?
That's its native ground. Soft, uneven, moving surfaces are what the shape is for — the wide base spreads across the foam instead of sinking a point into it, and the fins keep hold of the drink while the seat moves underneath. Nudge it off level and it comes back.
My sofa is microfiber — even plain water leaves a ring.
Then you know why blotting was never the answer. This resists tipping — it holds the drink steady and settles it back when the cushion moves. It isn't a lid, so on solvent-only fabric you can stack the layers: drop a lidded tumbler into it and the couch has two lines of defense.
Will it fit the arm of my sofa?
It doesn't have to — that's the point. Arm shapes are why clip-on trays are a fit lottery. This skips the arm entirely and sits on the seat cushion, the chaise, the ottoman, or the coffee table, with nothing to measure and no clamp range to check.
Will my 40 oz tumbler fit?
Yes — the 40 oz Stanley fits, and so does the 30 oz Yeti Rambler. The rule is the base, not the brand: 2 to 3 inches across settles in. Handled mugs are the exception — the handle lands where a fin needs to grip.
Does it attach to the sofa somehow?
No. Nothing clamps to the arm, wedges into the crease, or straps to anything. It sits on top of whatever surface you give it, moves seat to seat with you, and nothing needs undoing when you're done.
We have a no-drinks-on-the-couch rule for the kids.
Most houses with that rule wrote it after meeting the foam. A straw cup drops in and gets gripped by its bottom inch, which gives the cup one assigned spot instead of a wandering life on the cushions. It resists tipping rather than working miracles — but a held cup beats a loose one by a wide margin.
The dog uses the couch as a runway. Is that a dealbreaker?
A moving seat is the job, not the exception. The base rides the cushion as it pitches and settles the drink back level. It resists tipping, not physics — four paws square on the cup still win — but the bounce from a landing two cushions away is exactly the kind of hit it's built to take.
Can I use it on the coffee table too?
Yes — the table is the easy job. The same wide footprint and fin grip that manage a moving cushion keep a bumped drink from skating off the wood, which earns its keep on game night.
How do I clean it?
Rinse it in the sink or wipe it down — one molded piece, no seams, nothing to trap a spill. Skip the dishwasher; heat is the one thing not recommended. Compared to what the couch demands, it's a vacation.
Who makes it, and where do I buy one?
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 change your mind.
Made by
Molded a shorter reach than your coffee table.
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 together than your coffee table is to the couch you're on. The people who make it read hello@steadilabs.com themselves, usually before halftime.
Keep the drink beside you.
The glass stands on the cushion beside you — the coffee table goes back to holding magazines, the arm goes back to holding elbows, and the crease keeps only the remote.
