—A base for a blanket on a hill

No chair, a four-by-eight blanket, and a slope they built on purpose.

Name: The Concert Lawn Cup Holder
Brand: Steadi Labs

Of the 37 amphitheatres on Live Nation’s own list, 31 prohibit or plan to prohibit outside chairs. Where they are still allowed, the seat must sit no more than nine inches off the ground. Your blanket is capped at four feet by eight.

And the hill is deliberate: one venue’s own seating guide says the lawn “is designed with a steep slope, which helps improve sightlines”. This is a 5.2-inch base for that blanket, and it goes through a bag check.

The chair

31 of 37

banned, or soon

One shed puts it plainly: “No, outside lawn chairs are not allowed, but they can be rented in advance!” Where chairs survive, the rule is a “low profile style with a seat no more than 9 inches off the ground.”

The blanket

4′ × 8′

maximum

“Blanket: no larger than 4’x8’.” That is the entire surface you are allotted, and it is grass underneath it.

The drink

1 litre

factory-sealed

“Water: up to 1 (one) liter in a factory-sealed bottle, per patron.” So the thing you carry in is a bottle, and there is nowhere to stand it.

So: on the blanket

A 5.2-inch moulded base with nothing sharp on it. It flattens into a tote and it does not need anything pushed into the turf.

—Why the obvious product may not get in

“Spikes, studs, or any items that could cause harm.”

That is a prohibited-items line at a Live Nation shed
Ameris Bank Amphitheatre lists it as a category. Every ground stake in this aisle is a spike, and whether it clears the gate is a decision somebody makes while you are standing in the line.
The lawn is graded steeply enough to be an accessibility issue
One venue’s own page says “the terrain is on an incline, and after bad weather, it can become especially challenging to navigate”. At another, only one of two lawn ramps has “proper grade and handrails to meet ADA guidelines”.
Even where chairs are allowed, height is capped
Saratoga: “Lawn chairs on the center amphitheater lawn must not exceed 26″ in height when opened.” A 32-inch drink stake is taller than the chairs the venue permits.
And a chair rental is about $15
Per person, per show, according to trade coverage of the policy. Two people, three shows a summer, and you have spent ninety dollars renting somewhere to sit.

A hand sliding an aluminium can down into the fins of a Steadi. — Nothing sharp, nothing metal, nothing to declare.

—Does it actually work

It wobbles. Then it settles.

Somebody sits down on the blanket beside it, or steps past in the dark, and the drink comes back level instead of going over. The base is 5.2 inches across and spreads the load rather than balancing on a point.

Filmed on a couch cushion, which behaves a lot like a folded blanket over turf — soft, and it moves when somebody shifts their weight.

—How it holds

Width, and nothing else.

The base

5.2 inches across and fixed. It moves the edge the drink would have to tip over much further out, so the whole thing has to lean much further before it goes.

The fins

Six of them, holding the bottom inch. A sealed bottle drops in; a can slides on from the top. Drink and base then rock as one piece.

The blanket

A wide foot spreads across the fabric instead of pressing through it at a point. It does not make the slope level — nothing does — but it takes a great deal more lean before it goes.

—The object

One piece of rubber. Nothing sharp, nothing metal.

No spike, no stake, no steel, no folding legs and no glass. It is a moulded base that goes flat in a tote bag, and there is nothing on it for anybody at a gate to have an opinion about.

—What seats and what does not

The litre bottle you are allowed to bring in.

A factory-sealed one-litre water bottle is what most venues let you carry, and most of them are inside the two-to-three-inch range across the base. A standard 12 oz can is 2.6. A 40 oz Stanley is 3.1 and seats snug — though a venue may not let it in, which is their call and worth checking. A stemmed glass does not seat, and glass is prohibited at essentially every gate anyway.

Every width below comes from a published specification, not from us. Where a spec is uncertain, the answer says so.

Or the width across the bottom

Width in inches

A width across the bottom of the bottle, in inches.

Without a tape measure

A standard sticky note is three inches square. A bottle standing on one with its base inside the paper will seat.

Anything borderline — hello@steadilabs.com reaches a person, and the answer will be honest either way, including a no.

—Where they end up

The blanket, the cooler lid, and every bleacher after that.

The blanket on the lawn, which is the whole reason. Then the cooler lid at the tailgate before the doors open, a bleacher plank at a ball game, the folding table at a block party, and the arm of a low chair at the venues that still allow one.

Twelve colours, and the picker assigns one per unit, which on a dark lawn with four people on a blanket is how anybody finds theirs.

—What the aisle costs

Almost everything here is a spike, and spikes are on a list.

Prices were looked up on 3 September 2026, not estimated. Every figure is the seller’s own.

The product	Price	What it needs, and what the venue says
geckobrands beverage stake	$7.99	Soft ground to push into, and sized for “average-sized cups and bottles”. Sold as a beach and park item, not a concert one.
Steady Sticks stemware stakes	$9.99	“Holds any stemmed wine or champagne glass.” Glass is prohibited at essentially every amphitheatre gate.
Kreative Dilla sand spike	$15.99	A 6.25-inch spike designed for sand. Packed, sloped turf is a different material.
Steady Sticks picnic stake set	$19.99	A three-piece kit to carry in, against a clear-bag or small-clutch policy.
Yard game drink holder stakes, 32″	$34.95	“32″ tall so no more setting your cans in the ground.” Taller than the 26-inch chair limit on Saratoga’s centre lawn, and it stands in somebody’s sightline.
Heavy duty drink holder set of 7	$59.99	Welded steel. Bulk and metal mass against a bag policy and a wanding line.
The Concert Lawn Cup Holder	$14.95 · four for $39.95, $9.99 each	No spike, no metal, 3.6 ounces, flat in a tote. It stands on the blanket.

At a park or a back garden, the $7.99 stake is the better buy and it costs half what this does. It pushes into soft ground and holds a bottle upright, which is exactly the job. The reason it is not the answer here is that a shed lawn is packed turf on a grade, and “spikes, studs” appear on at least one Live Nation prohibited-items list.

We are not going to tell you what a specific gate will do on a specific night. Nobody can. Check your venue’s own page before you pack anything.

—From people who bought one

One of these is from a race, on sloped metal benches.

Verbatim, unedited, not filtered by rating. None is from an amphitheatre lawn and we are not going to imply otherwise — they are here because they describe a venue, a slope and a surface that was never meant to hold a drink.

★★★★★

Steadi- 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!

★★★★★

The Steadi has been popular for sitting out under a pop up canopy on lawn chairs and at a picnic at a nearby state park. We brought the four we ordered and have already placed an order for more since family members have claimed the first ones!

Every Friday is game night on the floor at our house and almost every Friday something spills. Not anymore. Thank you Steadi!

They also stay steady on the little wobbly patio table outside.

—The limits, in one place

What it does not do.

It does not make a slope level.
The lawn is graded deliberately, and on a real incline a drink standing in anything will lean. A wider foot buys a lot more tilt before it goes; it does not repeal the hill.
It does not go into the ground.
There is no spike and no stake. On bare turf with nothing under it, a flat foot sinks unevenly. It wants the blanket, a cooler lid or a bench.
We cannot promise what a gate will allow.
It has no spike, no metal and no glass, and it is 3.6 ounces of rubber. But policies differ by venue and change without notice, and no page on the internet can tell you what a specific security line will do on a specific night. Check your venue.
It is not spill-proof — nothing is.
It resists tipping by widening the footprint. A lawn in the dark with people crossing it will still get you eventually.
A handled mug does not seat, and a stemmed glass does not either.
The handle lands where the fins grip and the stem cannot seat. Glass is prohibited at most gates in any case.

—If it turns out to be the wrong thing

Ninety days. Used is fine. Nothing goes back in a box.

Ninety days covers a summer of shows. If the answer is no, hello@steadilabs.com reaches a person and the money comes back — no form, no restocking fee, no questions about condition, and nothing to pack up or post. Grass stains included.

You order. Free shipping, every order, always.

—Who makes it

Steadi Labs. One person, in Orange, California.

Scott Rodriguez made the first one after a full drink went over on a soft cushion with three kids under three in the house. It was built for spills, not for lawns.

Nobody at a shed asked for this page. It exists because a wide base does the same thing on a folded blanket as it does on a couch, and because the venues have published every constraint on the evening and nobody had put them in one place.

We make one thing and we make all of it here — the moulds, the material, the colour runs, everything within about three and a half miles of the shop.

—Questions

Straight answers.

Will it get through the gate?

We cannot promise that, and anybody who does is guessing. What we can tell you is what it is: 3.6 ounces of moulded rubber with no spike, no metal, no glass and no sharp edge. Policies differ by venue and change, so check your venue’s own page.

Does it stick into the grass?

No. There is no spike. It stands on the blanket, and that is deliberate — at least one Live Nation venue lists “spikes, studs” among prohibited items.

Will it work on a slope?

Better than the bottle alone, and not perfectly. The lawn is graded on purpose and nothing standing on it is truly level. A 5.2-inch foot takes much more lean before it tips, which on a hill is the whole benefit.

What about the litre of sealed water they let me bring?

Most one-litre bottles sit inside the two-to-three-inch range across the base and seat fine. If yours is unusual, measure the bottom and use the checker above.

Can I bring a chair instead?

At most Live Nation sheds, no — trade coverage puts it at 31 of 37 venues prohibiting or planning to prohibit them, with rentals around $15. Where chairs are allowed the seat has to be under nine inches.

Does it pack small?

2.8 inches tall, about 3.6 ounces, and they nest. Four go flat in a tote under a folded blanket.

Will it survive being sat on?

It is solid TPU with no hinge and nothing to snap. It will deform under a person and come back.

Why does this site only sell one thing?

Because it is one thing. It is a Steadi, made by Steadi Labs in Orange, California, and checkout finishes at steadilabs.com where the company lives.

—Still deciding

$14.95 when a stake is $7.99.

True, and at a park the stake is the better buy. The difference is a packed slope and a prohibited-items list with “spikes, studs” on it.

I’ll just hold it.

Most people do, for three hours, on a hill, in the dark. That is the actual competitor here and it is free.

Will it look like a gadget on a blanket?

It is a matte base 2.8 inches tall in twelve colours. On a lawn at dusk it reads as part of the drink.

Will I lose it in the dark?

Possibly, and that is a real risk on a lawn at eleven at night. One colour each helps. Stage Light exists for exactly this.

No chair, a four-by-eight blanket, and a slope they built on purpose.
