Every question, answered.

No — worth saying plainly. Drop it over the side of the mat and it sinks to the bottom like anything else that isn't foam. What it handles fine is everything short of that: a full soak, standing water, a wake washing straight over it. Rinse it off and it's back to work.

That's the surface it's built around. The wide flexible base spreads across the mat's flex instead of digging a point into it, and the fins grip the can or cup regardless of how wet everything is. Push it off level with a footstep and it settles back.

Measure the base, not the rim. A base of 2 to 3 inches across fits — the slim seltzer can does, and so does the 40 oz Stanley. Handled mugs don't; the handle gets in the way of the fins.

No. It doesn't tie off, clamp to a cleat, or suction to anything — which matters here, since wet gelcoat and wet foam are exactly where suction cups let go. It just sits on the mat, the swim platform, or the cooler lid.

That's the whole design brief. The base flexes with the ripple and settles the drink back level as it moves. It resists tipping, not physics — a direct kick off the mat's edge is still a direct kick — but a wake set or a cannonball two spots down is exactly what it's built to shrug off.

Yes — it holds at least as well on hard, flat surfaces like the swim platform or a cooler lid as it does on flexing foam. Useful, since that's exactly where drinks get parked during the climb on and off.

Rinse it with the hose or run it through the dishwasher. It's one piece of solid material with nothing to trap sand, salt, or lake water inside.

Better not to — most public beaches and swim areas ban glass outright. It's built around what actually makes it onto the mat: cans, seltzers, and lidded tumblers.

It's called the Steadi, molded in small runs in Orange, California by Steadi Labs — every order ships free from steadilabs.com, with 30 days to change your mind.

Large mats are rated for roughly 9 to 10 adults, or about 1,200 to 1,500 pounds of shifting weight, and every one of those footsteps ripples the same shared foam. There's no fixed formula, but most groups do better running one per drink in play rather than sharing a couple across the mat — the wide base holds its own footprint regardless of what's happening six feet away, but it can't hold a drink nobody's minding.

The sleeve's added weight helps once it's seated, but it fits the same way the can inside it does — gripped by the bottom inch, not by how heavy the whole thing is. A hard steel shell on flexing wet foam still tips on its own if nothing's gripping it; what the extra weight changes is how far it goes if it does. It's the same reason a neoprene koozie doesn't solve tipping by itself: it keeps a can cold, not upright.

Once a can or tumbler is seated, it's the fins gripping the container's bottom inch, not your hand, so sunscreen and condensation matter more on the way down than after it's settled in. That's worth knowing because everything on a lily pad compounds the same way — sunscreen hands, wet koozies, condensation on an insulated tumbler — and a stable set-down removes one variable instead of adding to the pile.

A wet dog coming aboard claws-first tilts the whole panel the way a person's knee does, just faster and less predictably. Quality closed-cell foam holds up fine against the claws; a drink standing unassisted near that edge is the part that doesn't. It's exactly the kind of ripple the wide base is built to shrug off — it settles back level instead of riding the tilt over.

It's one piece of solid, flexible material — no fabric, no foam core, no seams for sunscreen oil or saltwater to work into. That's a different failure mode than the mat's own foam or a neoprene koozie, both absorbent materials living in the sun and water all day.

Not on its own — it needs a surface to sit on, the same as anything else. In knee-to-waist water with no mat, platform, or cooler lid nearby, there's genuinely nowhere to set it down, which is why that stretch of the afternoon still means holding the can. Where it earns its keep is everywhere there's a spot to set something: the mat, the swim platform, the cooler lid.

It's built to work across the whole raft-up, not just one spot — the mat, the swim platform, and the cooler lid all hold it the same way. Someone who already owns a lily pad is exactly who's been improvising with a koozie or a suction cup that lets go, so it's a fair bet rather than a guess.

Not really, and it's worth saying plainly: those are high-sided vinyl with no flat spot anywhere on them, so there's nothing for a wide base to rest against. It's built for firm ground — the mat, the platform, a cooler lid — not a floating tube that's spinning and drifting on its own current.
