Every question, answered.

That's its home ground. Soft, uneven, shifting surfaces are what the shape is for: the wide flexible footprint spreads over the loose grains instead of drilling a socket, the fins hold the drink by its bottom inch, and when the sand re-settles underneath, the base settles with it and brings the drink back level.

The sea breeze mostly beats tall, light, half-empty containers standing on their own — the slim can is its favorite victim. Gripped low in a wide base, that same can resists tipping and holds steady through the gusts. It's not a force field — a direct hit from a stray frisbee is its own event — but wind pushing on a drink is exactly the load it's built for.

That's the one this is sized for. Judge the bottom, not the rim: a base 2 to 3 inches across settles in, and the 40 oz Stanley does. Handled mugs are the exception — the handle lands where a fin needs to grip.

Case by case. Foam widens the can's footprint and koozies vary, so run the sticky-note fit test with the koozie on — base inside the 3-inch square fits. A bare 12 oz can fits.

Sand rinses right out. It's one piece of flexible molded material — no mesh to trap grit, no seams, nothing to come apart. Shake it out at the car, rinse it at the beach shower, or run it through the dishwasher at home. Sand and a soaking don't hurt it.

No — nothing clamps to tubing, nothing stakes into the beach. It sits on the sand wherever your hand naturally falls from the chair, the spot the ankle-height spike and the armrest ring both miss. On the walk-down it packs flat in the wagon or the chair's backpack pouch.

Yes — it works at least as well on hard, flat surfaces. The wide footprint and the grip keep a bottle from skating on the condensation film, and a gust that would sweep a light can off the lid meets a drink held low and steady instead.

Straw cups and small bottles settle in as long as the base lands in the about-2-to-3-inch range — the sticky-note test works on their cups too. No cup holder can save the juice pouch.

It's called the Steadi, molded in small runs in Orange, California by Steadi Labs — veteran-founded and patent pending. Orders ship free from steadilabs.com, and you get 30 days to change your mind.

A stake's stability depends on how well it's planted — guidance for those stakes recommends tamping wetter sand and nesting the stake against a chair leg, which concedes what happens in dry, loose sand alone. It also parks the drink at ankle height, still a reach from a reclined chair, and a snug-fitting cup can pull the whole stake loose with it. This sits flat on top of the sand instead of driving into it, so there's nothing to plant, tamp, or pull out, and it lands wherever your hand naturally falls from the chair.

It's one piece of injection-molded material — no mesh to stretch out over time, no seams, and no metal clamp or hinge to corrode in salt air. Those are the exact failure points reported for armrest holders and clip-on mounts: mesh that quits gripping, clamps that loosen. A single molded piece doesn't have that failure built in.

No. It's one molded piece with no metal parts to corrode and no fabric or mesh to hold grit or salt against itself. Sand rinses out at the beach shower, and it can go through the dishwasher at home — a soaking doesn't hurt it either way.

It doesn't float — like anything solid, it sinks if it goes into the water. Wet hard-pack sand near the waterline belongs to the tide, so anything set down there, holder included, is on borrowed time once the water turns. Keep it up with the chairs in the dry sand and that's not a concern through a normal day of setup, recline, and cooler runs.

Yes — it comes in eight colors, from Storm and Deep Water to Sunset and Lifeguard Red, so each chair or each person can claim their own without a second glance at whose can is whose.

It solves one recurring problem — nowhere flat, dry, or level to set a drink on sand — so it's aimed at anyone hauling chairs and a cooler down for a real beach day. It packs flat enough for a beach bag or the zip pouch on the chair itself, an easy add to gear someone's already packing rather than one more bulky thing to store.

Yes — the fins read the base, not the rim, so the shape above it doesn't matter. A slim seltzer can (about 2.25 inches across), a standard 12 oz can (about 2.6 inches), and a 40 oz Stanley tumbler (about 3.1 inches, tapered) all land inside the 2 to 3 inch range the base is built for, and the flexible fins stretch to seat bases as wide as 3.15 inches for a snug fit. A base narrower than 2 inches sits too loose to grip.

A quick shake and rinse is enough — it's one piece of solid material with no mesh or fabric to trap moisture, so there's nothing inside it to hold water or mildew the way a wet towel or a fabric holder would. Tossing it in slightly damp with the rest of the gear isn't a problem.
