“First time I have ever ordered from Facebook feed. Very easy. Happy with product.”Steve Butler · 8 August 2026
A flexible-finned base holds your coffee, can, or 40 oz tumbler steady on the ground beside the chair — through the stand-up-to-cheer and the wagon ride to the next field.

Will your sideline tumbler fit? A sticky note has the answer — the test is below ↓
The problem, named
The chair came with a cup holder. It just doesn't work.
The whole sideline camp unfolds in minutes — chair, wagon, cooler, the team pop-up — and every piece of it has a job except the drink, which gets handed the same short list of bad spots every single game.
Sewn in when a bare 12 oz can was the only thing anyone brought to a game, it sags with a season of use and flexes with the whole chair frame. A 40 oz tumbler's base runs close to three inches — right at the width the loop was never cut to hold.
Natural fields are built with a deliberate crown or cross-slope so water drains off the pitch, which means the ground behind the touchline was never flat to begin with — and near the line it's already tufted and cleat-chewed before the morning dew has even burned off.
The sling fabric bows into a bowl under any weight. Set a cup on it while you jump up for the goal and the fabric leans it the second anyone else sits back down — which somebody always does, without checking.
The one flat surface at the whole setup, and it has to open every few minutes. Whatever's balanced on it at halftime gets picked up, knocked, or handed off to a kid the instant the lid needs to swing.
Plenty of leagues route spectators to the sideline opposite the bench — one rulebook sets them back two yards from the line itself — so the whole camp is a hike from the lot. Nothing extra makes that walk; whatever isn't already the chair, the cooler, or the wagon gets left behind, a proper drink table included.
It's not a disaster, any one time it happens. It's the relocation you run every few minutes for two hours, every Saturday of the season — chair to grass to cooler lid and back — until somewhere around the second tournament of the fall, it's just what you do without thinking about it.
The moments
You've watched every one of these happen from a folding chair.
Chairs snap open on grass still wet with dew. The drive-thru coffee won't seat in the mesh loop, so it goes down next to the chair leg — and goes over at the first whistle, because the ground under it was sloped toward the sideline all along.
Both hands push off the armrests, the frame racks, and the loop tips right along with it. You end up cheering one-handed, holding the tumbler yourself.
The whole camp — chairs, cooler, pop-up, kids — migrates to Field 6 in the wagon. Whatever was still half-full rides sideways on the fabric bed or gets left behind at the old field, forgotten in the scramble.
Every kid on the roster descends on the cooler at once. The drinks parked on its lid get handed off, set down in the grass, and found again by the first cleat through.
The 10-second check
One sticky note answers what the mesh loop can't.
lands in here
A square sticky note: 3 inches, exactly — the same ceiling the mesh loop never had to answer to.
The classic square is exactly 3 inches on a side. That's a fact about sticky notes — and it happens to be the exact ceiling of what fits.
Bottom, not rim — tumblers taper and a koozie rounds out a can, so the base is the only measurement that decides anything.
Base sits inside the square? It fits. Hangs over the edges? Too wide. A small puck lost in the middle — under 2 inches? Too narrow.
No tape measure at the sporting goods aisle, no guessing under the pop-up — just the tumbler that already rides to every game, checked once at the kitchen counter.
Plain mechanics
Built for ground that was never flat to begin with.
Sideline grass is cleat-chewed and graded to a slope by design. The wide, low base lies across both instead of balancing on one high tuft, so it never needed level ground to begin with.
Flexible fins hold the drink from the sides by its bottom inch, so a passing cleat, a sibling, or the family dog can brush it without knocking it loose.
It sits on the ground, not the armrest, so a flexed frame or a kid climbing over the arm never reaches it. A bump tips it off level and the low, wide base rocks it back.
Versus what you do now
Measured against the rest of the sideline kit.
| The chair's own mesh cup holder | The Sports Chair Cup Holder | |
|---|---|---|
| Fits a wide tumbler base | Sized for a can, not today's tumbler | Built for the wider base too |
| When you stand up to cheer | Frame flexes, the loop tips with it | Off the chair, holds steady through the stand-up |
| Moving to the next field | Stitched to this chair, stays behind | Rides in the wagon, sets down anywhere |
| On the cooler lid at halftime | Back at the chair, out of reach | Settles in there just as well |
| A cleat, sibling, or dog brushing past | Sags and lets go at a bump | Resists tipping through the brush-by |
| Reach from the seat | Right at the armrest, no reaching down | On the ground beside you, a reach down |
| Cost | Already stitched onto the chair | One small piece, a separate purchase |
The pattern across camp-chair reviews repeats itself: holders called shallow, tippy, and unable to secure a wider bottle, with drinks that go over the moment the sitter pushes up out of the chair. It was sized for a different era of cup, and it moves with the frame.
Reviewers report weak hinges and low-grade plastic that flexes under load; a clamp sized for one armrest tube fits few other chairs, and a full tumbler hanging off one side levers the clip loose or tips the whole light chair.
The complaint across buying guides is consistent — wobble — and the format only works where a spike can actually penetrate: not the tailgate lot's asphalt, not a turf field, not a bleacher plank, and it leans in soft ground after rain.
The category's own reviews admit a table that wobbles on uneven ground defeats the purpose — legs never find level on a crowned, tufted field, narrow feet sink into soft turf, and it's one more bulky item competing for space in a wagon that's already full.
From the reviews
What buyers say.
Real reviews of the Steadi — these ones mention sports life.
OMG!!!!! YOU HAVE TO BUY THESE!!!!!! i tested it out today on an old tv tray (wood and very slippery) and put a soda in it and played like “oops i bumped my tray” (and really hard) and NADA, NOPE, NOT AN INCH OF MOVEMENT from the STEADI. everything else went flying!!! cuz dummy me didn’t remove those other items first 🙃 duh!!! and no it was not suctioned to my tray cuz it doesn’t do that. but WOW!!!!! what a great invention. wish i was thinking up this GREAT IDEA, instead of binge watching TRAITORS tv shows and SPILLING my soda as i jump with excitement/anger over the show. the plus side, while flipping thru FB (while the commercial is on) or i’m cleaning up my spilt soda 🤪….. i saw this ad and it was like angels were singing “BUY ME AND UR PRAYERS ARE ANSWERED”. so glad i did. they work great!!! i bought the 4ct from actual website and it shipped quick and packaging was perfect. all 4 colors are great!! black, white, deep terracotta (plant holder) color. very very nice color. especially during the fall. and a muted warm sage color. very nice also. FYI:: i forgot to mention, i even tested this out with a 8oz dinner cup and it worked perfectly. but put the cup in FIRST then add beverage…..LOL learn from my dumb remark of “i can get it around the cup filled to the brim and not drop a lick of this drink. well WRONG!!!! 😑 LOL!!! user error not the STEADI. buy this and trust me u won’t want to return it. oh and it is comfortable to hold. and actually, now i can set my can of soda down with a mighty slap on the table and a huff and puff in disgust, if my tv show is calling for my dark side to come out in anger, of their decision of who to banish on TRAITORS (US/UK/NZ/ and now CANDA)!! ENJOY!!!! and THANK YOU TO THE INVENTOR!!!!! i hear it’s a father of 3. 🤷♀️
rebekah q. · 2026-06-23Steadi- Just what I was looking for! I purchased these to use at our annual NASCAR race this month. They delivered beyond my expectations. Our seats are metal benches with a slight slope towards the back, making it impossible to set down any type of drink. We were able to use these for a 20oz bottle with a koozie on it as well as a slim can with an insulated Brumate on it! They worked perfect, holding our drinks on the bench & on our cooler. I highly recommend for sporting fans, boaters, outdoor adventures. Thanks for making these!
Holly J. · 2026-06-09Steadi works very well in stabilizing my drinks on soft surfaces, like the couch or by the chair I use as a nightstand.
Marie A. · 2026-07-02My Steadi order arrived just as we were packing for our annual three generation family vacation. So into the car they went. Our time away is at a rental property and preventing spills in someone else’s house seems like a good goal. Additionally, most of our time is spent outside, at the house and nearby parks. The

Fair questions
You're probably thinking…
One piece of molded material — no hinge, clip, or fabric to fail — plus 90 days to run it through actual games before deciding it's not junk.
That loop is sewn into the exact part of the frame that flexes whenever you stand up to cheer — this one sits on the ground beside the chair instead, so standing up never touches it.
Base range is 2 to 3 inches and the 40 oz Stanley sits right in it, confirmed — and the sticky-note test lets you check your exact tumbler at the kitchen counter before it even ships.
It's one flat molded piece with no legs or parts, stows flat in the chair bag or a wagon pocket, and there's nothing to assemble or fold.
Free shipping on every order, and it's a rounding error next to the tumbler and the chair already in the trunk — this isn't the expensive part of the sideline kit.
Why more than one
Two identical Stanleys. Whose is whose?
Half the sideline is carrying the same 40 oz tumbler in the same handful of colors, and by halftime they've all landed in the same patch of grass beside the same row of chairs. Grab the wrong one out of the cooler swarm and you're drinking someone else's coffee, or handing your kid a stranger's Gatorade.

The fit question
The bottom inch decides what clears the mesh loop.
One rule covers every container below: a base 2 to 3 inches across settles in. Floor and ceiling both count.
- 40 oz Stanley-style Quencher tumbler fits
- Insulated steel tumbler (Yeti Rambler class) fits
- Drive-thru coffee cup fits
- 32 oz Gatorade squeeze bottle fits
- Standard 12 oz can fits
- Canned drink in a foam koozie fits
- Insulated steel water bottle (Hydro Flask class) fits
- Paper cup, poured from a shared thermos fits
- Kids' straw cup fits
- Coffee mug, handled handle in the way
- Espresso cup too narrow
- Wide-mouth 32 oz water bottle too wide
The floor matters as much as the ceiling — under 2 inches a base sits too loose to grip, and a wide-mouth bottle over 3 inches won't settle either. The handled coffee mug is the honest exception on this list: the base fits, but the handle lands exactly where a fin needs to grip.

The practicalities
Asked between games, answered here.
Does it actually work on sideline grass?
That's the terrain it's shaped for. Fields are graded to slope toward the touchline on purpose, and the grass near the line is tufted and cleat-chewed on top of that — a wide, low base spreads across all of it instead of balancing on the high points, and settles the drink back when it's bumped.
Does this replace my chair's cup holder?
It doesn't attach to it — it sits on the ground beside the chair instead, which solves the actual complaint: the sewn-in loop sags and tips whenever the chair frame flexes, most of all when you stand up. This holds steady because it isn't riding the chair at all.
Will my 40 oz tumbler fit?
Measure the bottom, not the rim. A base of 2 to 3 inches across settles in, and the 40 oz Stanley does — it's the tumbler most mesh loops were never built for. Handled mugs are the exception: the base fits, but the handle gets in the way of the fins.
What happens when I jump up to cheer?
Nothing — the drink isn't on the chair. It's on the ground beside it, so a flexing frame or a knee against the arm never reaches it, which is precisely the moment the built-in mesh loop fails.
Can I use it on the cooler lid or a bench instead of the grass?
Yes — it works at least as well on hard, flat surfaces. On a cooler lid or a bench the wide base and the grip keep a bumped drink from sliding, which matters just as much up there as it does on grass.
Does it travel to the next field for a doubleheader?
It rides in the wagon or the chair bag with the rest of the kit — no legs, no hardware, nothing to fold. Set it back down beside the chair at Field 6 and it works exactly like it did at Field 2.
It rained and the ground is soft. Does that change anything?
It's built for exactly that. Chair legs are small points that sink into soft, wet turf and tilt the whole chair, holder included. The wide base spreads the same weight instead, so it settles into soft ground rather than sinking into it.
How do I clean it after a season of dew, grass, and dropped snacks?
Rinse it, wipe it down, or put it in the dishwasher. It's one piece of flexible molded material with nothing to come apart, and getting soaked doesn't bother it.
