“Brilliant idea. These are great on the boat!! Hold up nicely in the wind when my can is almost empty.”
A CUP HOLDER FOR YOUR FLOATING MAT
Put your drink down.
Enjoy the float.
Steadi gives your drink a wider base on the mat, so you can keep it beside you instead of holding it the whole time.
From $14.95 · Free US shipping · 90-day guarantee
Fits cans, bottles, cups & tumblers.
For use on top of a supported mat. Steadi does not float or attach; keep it clear of the edges.

MAKE ROOM FOR BOTH OF YOU
One for you.
One for your floating partner.
Choose your pack, then give each drink its own color.
Support the full base and leave room around it. Steadi can still tip, slide or be knocked off; your mat and conditions matter. See the inflatable platform shown.

REAL MAT. REAL MOVEMENT.
See what happens
on the water.
Three fitted cans sit on the gray deck of an inflatable lake platform. The holders remain upright through the movement shown.
This continuous, normal-speed clip shows drinks already placed on the mat. It does not show the full placement-and-pickup sequence or establish results on flexible foam mats.
Fill levels and inflation pressure were not recorded. Steadi can still tip, slide or be knocked off. Support its complete base, away from the edges.

A WIDER PLACE TO LAND
A little more
room to relax.
Grip your drink.
Six flexible fins hold the lower part of a compatible container.
Give it a wider base.
The 5.2-inch base broadens its support footprint to help resist tipping. No suction, adhesive or attachment.
Keep it beside you.
Set the entire base on a supported part of the mat, within easy reach.
BRING YOUR USUAL
Can today.
Tumbler tomorrow.
Start with the bottom of your drink. That’s the part Steadi holds.
That’s the regular base-fit range. Up to 3.15 inches is a snug fit. Measure the base, not the widest part of the cup.
Measure the base, not the rim. A very narrow base can be loose, and a low handle can block a fin.
Fit is specific to the container. The Quencher H2.0 example doesn’t mean every 40 oz tumbler fits.
FROM STEADI OWNERS
A little thing.
A welcome addition.
Steadi goes beyond a day on the mat. Here’s what customers have shared about using it.
“My friends love the Steadis. Their motorboat had no place for drinks, and no flat surfaces!”
These are customer accounts of boat use, not floating-mat tests. Read Steadi reviews ↗
Does the cup holder float?
No. Steadi sits on a mat or another supported surface; it is not a floating drink ring. If it goes overboard, it sinks. Keep it clear of the edge.
Will it work on my floating mat?
The real video shows an inflatable lake mat/platform. Steadi needs its full base supported. We haven’t shown a controlled test on every mat, including soft foam lily pads. The mat’s firmness, slope, movement and the drink you use all matter. We have not verified flexible foam-mat performance.
Does it stop every spill?
No. The broad base and gripping fins help resist tipping; they don’t make the drink spill-proof or attach it to the mat. A strong impact, a sharply tilted surface or a kick can still knock it over.
Do I need to attach it to the mat?
No. It’s freestanding. Fit the lower part of your drink between the fins and place the complete base on the surface. There are no clamps, suction cups or adhesives.
Will my drink fit?
Fits cans, bottles, cups & tumblers with compatible bases. The regular range is 2–3 inches across; up to 3.15 inches is snug. The exact 40 oz Stanley Quencher H2.0 and 7.5 oz mini cans are owner-confirmed examples. See the fit guidance.
How do I clean it?
Rinse it, wipe it down, or put it in the dishwasher. Steadi is one molded piece of TPU, with no springs or hardware to take apart.
What comes in the box?
The number of Steadi holders in your selected pack, in your chosen colors. Drink containers, drinks and the floating mat are not included.
