Every question, answered.

No — worth saying plainly before anything else: send it into the water off the coping and it sinks straight to the bottom, no float built in. Fish it out and rinse it off and it works exactly the same; the material doesn't mind soaking. It's built to sit at the water's edge, not on it.

Measure the base, not the label. A base 2 to 3 inches across settles in — a standard can, a slim seltzer, and the 40 oz Stanley all land in that range. A handled mug doesn't; the handle sits right where a fin needs to close.

That call belongs to your pool, not this product — glass is banned at essentially every pool because a break underwater is close to invisible and everyone's barefoot. This is built for what the no-glass rule leaves you: cans, pouches, and plastic tumblers, which is most of what actually comes out to the deck anyway.

Yes — that's most of what it's built for. Vinyl straps and sling mesh flex under a narrow can or a rigid clip with nothing to hold onto; the wide flexible base rides that give instead of needing a flat spot to sit on.

Yes, at least as well as it works on the soft and uneven stuff. The wide base and the grip on the drink itself hold just as well on concrete, pavers, or a patio table as they do on a strap chaise or a curved coping edge.

It resists tipping and settles back through the ordinary chop of splashing kids and a bubbler, so plenty of people do. Just remember it isn't a float — if it goes over on its own and drifts into deeper water, it goes to the bottom, same as it would off the coping.

It isn't inflatable and it isn't buoyant, so there's nothing for the wind to grab and walk across the deck the way it does a flamingo float. The wide base and the grip on the drink are what a floating holder has neither of.

Rinse it under the hose or run it through the dishwasher — one piece of flexible material, nothing to unclip and nothing that comes apart.

The product is called the Steadi. It's molded in small runs in Orange, California by Steadi Labs — veteran-founded, patent pending — and every order ships free from steadilabs.com, with 30 days to send it back.

Splash, chlorine, and direct sun aren't an edge case for it — they're the every day. It's one piece of molded material with nothing to unclip, corrode, or spring open, so there's no hinge or fastener for pool chemicals to work on. If a season of real pool days doesn't hold up the way this page says, the 30-day guarantee is there to fix it, no forms required.

No — the base itself is soft, flexible material sitting flat against the surface, not a hard foot or a metal fixture, so it isn't the kind of contact that scratches pavers or travertine. The more common poolside deck mark, a condensation ring, comes from the drink sweating directly onto the tile — setting a can on the base instead keeps that ring off the deck in the first place.

Yes — Yeti lists both the 20 oz and 30 oz Rambler tumblers at a 2.75-inch base, comfortably inside the 2-to-3-inch range that settles in fully.

Those are the honest misses at that size: a 32 oz Hydro Flask Wide Mouth runs about 3.58 inches at the base, a 32 oz Nalgene Wide Mouth about 3.5, and the 32 oz Owala FreeSip about 3.43 — all past the 3.15-inch flex ceiling the fins can seat. Size down and it changes: the 24 oz Owala FreeSip measures 3.12 inches, right at the snug edge of that flex range, and seats with a push.

That's a headcount question more than a design one — nothing clips to one chair or one spot, so however many people are actually holding drinks is the right number. The color names make it easy to tell whose is whose across a crowded deck; Deep End and Shallow End read apart from six feet away the way a matched set doesn't.

It fits that gift well — a new pool owner usually hits the no-flat-surface problem within the first couple of weeks, and this answers a specific, recognizable annoyance rather than being a generic housewarming item. One thing worth knowing before wrapping it: it doesn't float, so it isn't a pool toy — it's built to live on the deck, the chaise, and the ledge, not to bob around in the water.

The sippy cup, yes — most kids' sippy cups fall inside the base range and settle in the same way an adult tumbler does. A juice pouch doesn't, but not because of width: pouches lie flat instead of standing on a round base, so there's no footprint for the fins to close around. It's a shape mismatch, not a size one.

It's a common poolside fix, and it solves a narrower problem than it looks like. A noodle segment floats a can in the water, but it's still untethered — the same breeze that walks an inflatable flamingo across the pool walks a noodle-and-can just as easily — and it does nothing once you're back on the chaise or the deck, where there's no water for it to float on in the first place.

No — it's a grip, not an insulator, and it isn't trying to do a koozie's job. A can in a foam koozie or an insulated tumbler fits the same way a bare can does, so pairing the two is normal: the koozie keeps the drink cold, the base keeps the koozie from sliding off the strap chaise or the coping in the first place.

Nothing special — rinse it, let it dry, and toss it in a drawer or the pool-toy bin until the cover comes back off. It's one solid piece with nothing that corrodes shut or needs re-greasing, so there's no off-season prep beyond getting it clean and dry before it sits for a few months.
