—A base for the lid, not a spike for the sand

The cooler lid is the flattest thing out there. There is nothing in it.

Name: The Beach Cup Holder
Brand: Steadi Labs

On a YETI Tundra that is by design — the body and lid are moulded as one piece of polyethylene with no seam, which is what makes it a good cooler and why nothing is sunk into the top of it.

If your drink is going in the sand, buy a spike. They cost $10 to $16, they work, and we name them below. This is for the lid, the flat arm, the table and the towel — where a spike has nothing to push into.

—Three surfaces, three different answers

Only one of these is ours, and we will tell you which.

Every figure below is the seller’s own published number, looked up on 3 September 2026. Where nobody publishes a number, that is said outright, because it is the most useful thing on the page.

In the sand

$10–$16

buy a spike

A sand spike is the right tool and it is cheap. Marshmallow Dream’s Spiker is $10 with an 8-inch body; Kreative Dilla’s is $15.99 with a 3.75-inch holder on a 6.25-inch spike. Not us.

In the chair

Unknown

nobody publishes a size

Tommy Bahama’s holder is described only as “adjustable… to hold almost any size drink.” Their lay-flat chair uses an “insulated zip up cup holder” — fabric. No maker publishes a diameter, so you cannot check before you buy.

On the lid

Nothing there

a bare slab

“No seam construction – body and lid are made out of one piece of Polyethylene.” A Tundra 45 lid is roughly 25.6 by 15.9 inches of flat, unbroken plastic.

So: the lid

$14.95

a flat surface

A 5.2-inch moulded base, 3.6 ounces. The lid, a flat chair arm, a beach table, a towel over packed sand. It does not go in sand, and it does not pretend to.

—Why the chair pocket keeps losing

A pocket has to swallow the cup. This only holds the bottom of it.

A 30 oz Rambler is four inches across the body
YETI publishes it: “The Rambler 30 oz. Tumbler measures 7 7/8″ tall and 4″ wide.” The Spiker’s pocket is three inches. The cup is simply wider than the hole.
Which is the difference between the two designs
A pocket, a well or a spike has to take the widest part of the container. Six fins gripping the bottom inch have to take the narrowest part — the base, which on that same Rambler is well under three inches.
Nobody publishes a chair-pocket diameter. Anybody.
Not Tommy Bahama, not RIO, not Coleman. We went looking specifically to put their number next to ours and there is not one to find. The nearest published figure anywhere is 7 cm — about 2.75 inches — on a moulded Adirondack armrest.
And the chair is low
Tommy Bahama’s raised “easy in-easy out” chair sits at 12.75 inches, and that is the tall one; a Hi-Boy backpack chair reaches 17. Everything at that height is in the sand or nearly in it.

A hand sliding an aluminium can down into the fins of a Steadi. — The fins take the bottom inch. Nothing has to swallow the cup.

—Does it actually work

It wobbles. Then it settles.

Somebody knocks the cooler shutting it, or drops onto the towel beside it, and the drink comes back level. The base is 5.2 inches across and spreads the load rather than balancing on a point.

Filmed on a couch cushion — softer and less predictable than a cooler lid, which is the easiest surface it has.

—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. Cans and bottles slide on from the top; tumblers and glasses drop in. Drink and base then rock as one piece.

The lid

A wide foot on a hard, level, unbroken surface is the easiest job this product has. Salt water and sunscreen do not hurt it, and it rinses under a tap.

—The object

One piece of rubber. Nothing to lose in the sand.

No spike, no clamp, no fabric, no clip and no parts. It is a single moulded piece that packs flat in the bag with the towels and rinses off under the shower on the way out.

—What seats and what does not

Measure the bottom, not the widest part.

This is the whole difference between the two kinds of product. A pocket or a spike has to be wider than the widest part of your cup — which on a 30 oz Rambler is the four inches YETI publishes. Six fins gripping the bottom inch only have to take the base, which is much narrower. Two to three inches across the bottom settles in; three to 3.15 is snug. A handled mug does not seat at all.

Search by container

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

Container

Or the width across the bottom

Width in inches

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

Without a tape measure

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

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

—Where they end up

The lid, the flat arm, the table, the towel.

The cooler lid first, because it is hard and level and already there. Then a chair arm if yours has a flat one, the table at a beach house, a towel spread over packed sand near the water line, and the tailgate on the way home.

Twelve colours, and the picker assigns one per unit, which on a beach with three families on it is genuinely how you find yours again.

—What the aisle costs

Three of these are cheaper than we are. Two of them are better, in sand.

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

The product	Price	What it needs, in its own words
RIO Beach Multi Sip Clip	$1.59	“Will fit all our wood arms chair.” A specific chair, and sold in packs of twelve ($19.08).
Spiker sand cup holder	$10.00	Sand. Eight inches overall, and the pocket is three inches across — narrower than the four-inch body of a 30 oz Rambler.
Kreative Dilla beach cup holder	$15.99	Sand deep and firm enough for a 6.25-inch spike. Holder 3.75 inches across.
Sand spike, double cup with shelf	$40.00	Sand, and carrying four pounds of HDPE that is 19 inches wide down to the water.
Coleman 316 Series 65-quart wheeled cooler	$59.99	Nothing — it already has drained holders moulded into the lid that “fit up to a 30-oz. tumbler.” If you are buying a cooler anyway, buy this one.
The Beach Cup Holder	$14.95 · four for $39.95, $9.99 each	A flat surface. Any flat surface, and it comes home in the bag.

In sand, the spike wins and it is cheaper. That is not a hedge, it is the correct answer: a spike pushes into sand and this does not. And if your cooler is due for replacement, the Coleman with moulded lid holders solves it for the price of a cooler you were buying anyway.

What none of them do is come back to the house and work on the counter, the patio table and the arm of the sofa, which is where most of these end up living for the other fifty weeks.

One of these names a cooler lid.

None is from a beach, and we are not going to imply otherwise. They are here because they describe outdoor surfaces that are not level and not indoors. Verbatim, unedited, not filtered by rating.

★★★★★

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.

★★★★★

Most of our time is spent outside, at the house and nearby parks. 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!

My friends love the Steadis. Their motorboat had no place for drinks, and no flat surfaces!

—The limits, in one place

What it does not do.

It does not go in sand.
There is no spike and no stake. On loose dry sand it sinks and leans like anything else with a flat foot. For sand, buy a sand spike — they are $10 to $16 and they are the right tool. This needs something firm and level under it.
Wind is not something it resists.
An empty can goes over in enough wind whatever it is standing in. This widens the base; it does not add weight, and 3.6 ounces is not much on an exposed beach.
It is not spill-proof — nothing is.
It resists tipping by widening the footprint. A kicked drink is a kicked drink, and there are a lot of feet at a beach.
A handled mug does not seat.
The handle lands exactly where the fins grip. A stemmed glass is a straight no as well.
It does not insulate.
It is a base. Your koozie, your Rambler and the cooler are doing that job and this does not help them.

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 beaches.

It is about forty minutes from the shop in Orange to the sand, which is the entire reason this page exists — and also why it says plainly that in sand you should buy a spike instead.

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.

Does it stick in the sand?

No. It has no spike and it is not meant to. On loose sand it sinks and leans. If sand is where your drink goes, a sand spike is the right product and it costs less than this.

Then what is it for at a beach?

The cooler lid, a flat chair arm, a beach-house table, a towel spread over packed sand, and the tailgate. Anything hard and level.

Will a 30 oz Rambler fit?

Yes. The four inches YETI publishes is the widest part of the tumbler; the fins only grip the bottom inch, which is much narrower. That is why it clears this and not a three-inch pocket.

Does salt water hurt it?

No. It is Shore 85A TPU with no metal and no moving parts. Rinse it at the shower on the way out, or run it through the dishwasher at home.

Will it blow away?

Empty, in enough wind, yes — it is 3.6 ounces. So will an empty can standing in anything. Nothing here is weighted.

What about the chair I already own?

If the arm has a flat top, it works there. If your chair’s holder is a fabric pouch, that pouch is doing a different job and this is not a replacement for it.

Does it pack flat?

It is 2.8 inches tall and 3.6 ounces, and they nest. Four take up less bag than a folded towel.

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 spike is $10.

True, and in sand the spike is the better buy. The difference is that the spike only works in sand, and this works on the lid, the table, the tailgate and the couch at home.

My chair has a cup holder.

Most do, and most are fabric. Nobody publishes what size cup theirs takes — we went looking. If yours holds your tumbler, you do not need this for the chair.

Will it get lost in the sand?

It is 5.2 inches across and comes in twelve colours, several of which are deliberately not sand-coloured. Order a bright one if that is a real worry — that is what Lemon is for.

Is it another thing to carry?

3.6 ounces each and they nest. Compared with a 4-pound, 19-inch sand caddy, this is the light option.

The cooler lid is the flattest thing out there. There is nothing in it.

Only one of these is ours, and we will tell you which.
