You've lived this
Every movie night has run into one of these.
The drink lands on the carpet by the couch leg because the coffee table's out of reach once the blanket's arranged — and from that moment it's invisible until somebody's foot finds it.
The whole couch flinches at once, and whatever was balanced on a lap, a cushion, or an armrest goes over with it — the spilled bowl of popcorn is such a fixture of horror night that critics joke a scary movie isn't working if nothing spills.
Legs have gone numb, so everyone reshuffles — the cushions re-slope under the new weight, and the can that had been sitting fine for an hour tips straight into the seam between seats.
Someone stands up off the cushion, the foam rebounds, and the neighbor's drink goes with it — while whoever's walking to the kitchen picks through a dark floor lined with everyone else's cups.
A kid climbs across the sectional for the snack bowl, crossing right over the drink zone, and the dog launches off the cushions at a doorbell buried in the soundtrack.
What it does
What holds for the whole runtime.
Holds steady on the cushion, not just the coffee table
The wide, low base spreads across the seat cushion or the blanket over your lap instead of balancing on a single point. Shift your weight, stand up for a refill, sit back down — its wide base of support keeps it from tipping, and the drink settles back down.
Grips what you actually bring to the couch
The can, the tumbler, the wine glass, the kids' sippy cup at family movie night — drinks slide on or drop through the fins and get held by the bottom inch, not by the walls of a tray built for something narrower.
Doesn't care what your armrest looks like
No clamp, no flat-arm minimum, nothing that only works if your sofa happens to be built right. It sits on the cushion, the blanket, or the ottoman lid — wherever you're actually sitting — and clears away in a second when the credits roll.
The sticky-note check
Settle the fit question before the opening credits.
lands in here
A square sticky note: 3 inches, exactly — the same ceiling that decides what stays on the couch.
That size is fixed at exactly 3 inches per side. It's a fact about the sticky note, not about your drink — and it happens to mark the outer edge of what fits.
Set it down the way you would beside the cushion, not on a kitchen counter. Look at the base, not the rim — a Stanley tapers, a wine glass flares, and only the bottom decides whether it stands or tips.
Base sits inside the square, all the way around? It stays wherever you set it. Hangs over an edge? Too wide. A small circle lost in the middle — under 2 inches? Too narrow to grip.
No ruler, no tape measure, no guessing in the dark. One sticky note under the lamp before the movie starts, with the tumbler you're actually bringing to the couch.
Why more than one
Two identical tumblers. Whose is whose?
Movie night rarely means just one drink — it's the couple's standing Sunday-night ritual, or the whole sectional watching together, and more than one person usually reaches for the same 40 oz Stanley color. Once the lights go down and both cups land on the same dark cushion, there's no telling which one is actually yours.
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.
Compatibility
The bottom inch decides what stays for the show.
One rule decides every verdict below: a container base 2 to 3 inches across settles in and stays. Everything else follows from that line.
- 12 oz soda can fits
- Slim seltzer can fits
- 40 oz Stanley-style tumbler fits
- Stemmed wine glass fits
- Stemless wine glass fits
- Handled mug of cocoa or tea handle in the way
- Longneck beer bottle fits
- Pint glass fits
- Kids' straw or sippy cup fits
There's a floor as well as a ceiling — under 2 inches, the base sits too loose to grip. The handled mug is the honest exception on this list: the mug itself fits, but the handle sits exactly where a fin needs to close.

From the reviews
What buyers say.
Recent reviews of the Steadi, from every room and rig it lives in.
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 mine. I just wish the price was more appropriate. $15 seems a lot for a small plastic item. Reduce it to $9.99 and free shipping and I'll buy a few more!
Carolyn G. · 2026-08-27Excellent!

Fair questions
You're probably thinking…
The 40oz Stanley fits — confirmed, no asterisk. If you want to check it yourself before you click buy, a sticky note is exactly 3 inches on a side; stand your tumbler's base on it and see the same fit for yourself.
The wording is the tell: it resists tipping and settles in, not 'never spills' — because it isn't invincible and we're not pretending it is. Real reviews from other movie nights, and 90 days to send it back if it doesn't hold up on yours.
Right on the cushion or the blanket over your lap. Nothing to clip onto, nothing to reach for — the missing side table stops being the problem it is for every clip-on tray.
This doesn't ask your armrest to be anything. No clamp, no flat-arm minimum — it sits on the cushion, the arm, or the blanket, whatever shape your couch actually is.
That's named directly, not glossed over: ordinary bumps from a house with kids and pets in it are what this holds through. It's not indestructible — a hand landing straight on a full cup will still spill it — but a startled couch is exactly what it's built for.
Good to know
Asked before the lights go down, answered here.
Does it actually work sitting on a couch cushion?
That's the terrain it's built for. The wide, low base spreads across the cushion instead of pressing into one spot, and the fins keep the drink from sliding loose when the couch jostles at a jump scare. Bump it off level and it settles back.
My armrest is rounded and padded — will anything actually sit on it?
This doesn't ask the armrest to be flat at all. It sits on the cushion, the blanket over your lap, or the ottoman lid instead, so a crowned or pillow-top arm stops being the problem it is for clip-on trays.
I've got a sectional with no side table anywhere near the chaise end.
Then there's nothing to clip to and nothing to reach for. It sits directly on the cushion or blanket beside you, so the missing side table stops mattering.
Will my tumbler actually fit?
Measure the bottom, not the rim. A base 2 to 3 inches across settles in — the 40 oz Stanley fits. Handled mugs don't; the handle sits where a fin needs to grip.
It's always dark for movies — will I lose track of it like I do with a glass on the floor?
It's not on the floor to begin with. It's on the cushion, the arm, or the blanket you're already touching, right where your hand already is, not down on the carpet where a glass disappears.
What happens during a jump scare, when the whole couch jolts?
That's the exact motion the fins are built to shrug off — they hold the drink's base and it resists tipping when the couch flinches. It's not invincible, so a direct hard knock is still a direct hard knock, but a startled couch is what this is for.
Does it hold up outside, for a backyard projector night?
Yes — uneven, moving ground is where this holds up best, grass included. It plants on damp lawn the same way it plants on a cushion, so the projector setup on the grass gets the same steady base as the couch does.
Does it clip onto the arm or clamp to the couch somewhere?
No. Nothing clips, clamps, or attaches to anything. It sits on top of the cushion, the arm, the blanket, or the ottoman lid, and it tucks into a drawer between movie nights.
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.
Ninety days of real movie nights.
Watch with it for a month. If it doesn't do what this page says — on the cushion, the arm, or the blanket over your lap — email hello@steadilabs.com and it gets made right. No forms, no fight.

Behind it
Molded not far from wherever you're watching.
The maker is Steadi Labs, a small veteran-founded company in Orange, California. It's injection molded in small runs, 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, usually between showings.
Watch the whole movie, not the drink.
The drink stays put on the cushion, the arm, or the blanket — through the jump scares, the reshuffles, and the three-hour epic — while the floor stays clear for the walk to the kitchen.
