Every question, answered.

That's the exact motion this is built for. A graze from a reaching elbow moves the wide base before it moves the drink — the fins hold the cup by its bottom inch and the base rocks back to level. It resists tipping; a direct hard knock is still a hard knock, but the everyday reach across the puzzle is what it's made to shrug off.

No — the base doesn't depend on the table holding still. The wide footprint and the fin grip hold steady whether the tabletop is solid wood or a folding card table with some flex in the legs. On hard, flat surfaces it works at least as well as it does anywhere else.

Measure the bottom, not the top. A base 2 to 3 inches across settles in — the 40 oz Stanley does. A handled mug doesn't; the handle sits right where a fin needs to close around the base.

It's meant for the table or shelf beside the board, not the felt itself — that space belongs to the puzzle. Set it on the tabletop next to the board, the arm of the chair, or the shelf of a folding table, and it holds there the same way it does on a bare desk.

Not on the sloped work surface itself — nothing sits level on a 20-to-30-degree incline, this included. Set it on the table or the stand beside the easel instead, and it holds there the way it does on any hard, flat surface.

Anywhere flat that isn't the puzzle itself — the sliver of table by the box lid, the arm of the chair, the shelf of a card table. It doesn't need a coaster or a dedicated corner, just a few inches that aren't already pieces.

It resists tipping and holds the drink steady through the kind of graze that usually starts a spill — but it's not a sealed lid, so pair it with a lidded tumbler for the sessions where the stakes are highest.

Rinse it or wipe it down — one piece of flexible material with nothing to take apart, and no felt or fabric to catch puzzle dust. Skip the dishwasher; heat is the one thing not recommended.

The Steadi is 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 if it's not for you.

Base width decides it, not shape. A standard 12 oz can measures about 2.6 inches across its base, and the slimmer "sleek" cans common with seltzer run about 2.25 to 2.28 inches — both settle inside the 2-to-3-inch range. Cans and bottles slide on rather than dropping in through the fins the way a glass or tumbler does, but the base still has to land in range either way.

Puzzle dust — the fine cardboard chaff that collects in the box and on a felt board — doesn't have anywhere to hide here. It's one piece of flexible material with no seams or fabric to trap it in; rinse it under the tap between sessions and it comes out clean — skip the dishwasher; heat is the one thing not recommended.

It's molded as one piece of flexible material with no hinge, spring, or clamp mechanism to work loose — the parts that fail first on a clip-on holder simply aren't there. A quick rinse or a wipe-down after a session is all the care it needs — skip the dishwasher; heat is the one thing not recommended.

Yes — the fins grip the bottom inch of whatever's set into them regardless of temperature, so a cold can early on and a hot, handle-less travel cup later in the evening both hold the same way. Container shape and base width are what decide the fit, not what's inside.

Nothing stops it — each base is a single flat footprint, smaller than a coaster stack, so a few can sit around the same table without adding to the clutter the puzzle's already created. Everyone keeps a drink at their own seat instead of sharing the one clear inch on the table.

It's a fair one — it solves a problem every serious dissectologist already has, whether they've named it that or not. The color options are even named for a puzzle's own sections (Sky Section, Meadow Section, Poppy Section, and the rest), a detail that reads as puzzle-specific rather than generic.

No — the wide base and fin grip perform the same on a folding card table as anywhere else; hard, flat surfaces hold this at least as well as any other surface it's used on. A card table set up specifically to free the dining table for meals doesn't change the physics — what matters is a flat few inches, not which room or which piece of furniture supplies it.

It can — this holds the container steady, it doesn't stop a cold glass from sweating in a warm room. If a condensation ring near loose pieces is the real worry, a handle-less insulated cup or a lidded tumbler keeps the outside dry the way a bare glass can't, and either one still sits in the fit range the same as anything else.

A coaster answers the ring; it does nothing when an elbow or a sleeve catches the glass mid-reach, which is when the documented puzzle-table spills actually happen. This is built for that motion specifically — the wide base and the fins gripping the bottom inch mean a graze moves the base before it moves the drink, instead of doing nothing until the glass is already going over.

Yes, the same way it works next to a felt board — set it on the table or shelf beside the mat, not on the mat's rolled fabric itself, which isn't a flat surface to begin with. Once the puzzle's back in the mat and rolled away, the base stows just as flat, in a drawer or alongside the sorting trays.
