The clamp is for the chair. This is for the table.

—Read this before anything else

Two halves of the same day.

Search this category and you get clamps. They are good products and they solve the moving half. This solves the other one, and it is worth knowing which you are buying before you spend anything.

Most people who need the first also have the second. They are not alternatives, and nothing here asks you to choose.

—Where a glass on a table goes wrong

Three moments, and none of them is drinking.

• The set-down

  The glass lands about where it was aimed. A 5.2-inch base is wider than the difference.

• The reach

  Something catches the rim on the way past. On a wide base the glass rocks and settles rather than going over.

• The knock

  The table gets bumped by somebody else entirely, which is the one nobody can do anything about.

—How it holds

The base

5.2 inches across and fixed. It moves the edge the glass would have to tip over much farther out, so the whole thing has to lean much farther before it goes.

The fins

Six of them, holding the bottom inch. Glasses and tumblers drop in; cans and bottles slide on. Glass and base then rock as one piece.

The surface

The rubber plants the base where it is set and lifts away clean. It marks nothing and there is nothing to adjust.

See the packs — from $14.95

—The object

One piece of rubber. Nothing opens, closes or tightens.

There is nothing to assemble, nothing to set up, nothing to fit and nothing to put away. It goes on the table and the glass goes in it.

—What seats and what does not

The glass you already own, or nothing.

Nothing here needs replacing. What seats is a glass, a tumbler, a can, a bottle, or a lightweight plastic cup. A mug with a handle does not seat — the handle lands exactly where the fins grip — and that includes the two-handle mugs this aisle sells.

Or the width across the bottom

A width across the bottom of the glass, in inches.

—Where they end up

Wherever the glass already gets put down.

The table that gets used. The one by the bed. A desk, a side table, a tray that is standing still. They stay where they are put, which is the point — a thing that lives in a drawer is a thing that is in the drawer on the day it was needed.

—What the aisle costs

The aisle, with prices.

Prices were looked up, not estimated, on 3 September 2026. Everything above the line does a different job from everything below it.

A mat grips. This grips and is 5.2 inches wide. Those are two different jobs, and a mat is the right buy if what you need is for things to stop sliding on a tray.

Nothing on that list is meaningfully cheaper — the least expensive mat undercuts us by twenty-five cents — and most of it costs twice what this does or more. That is a fact about the aisle rather than an argument.

—From people who bought one

Two of these are from disabled customers.

They say so themselves; we have not inferred it and we have not asked anybody. They are here because they describe the surface and the reach, which is what this page claims. Verbatim, unedited, not filtered by rating.

—The limits, in one place

What it does not do.

• It does not attach to anything.

  No clamp, no bracket, no strap, no hardware. It cannot be fitted to a chair, a walker, a rail or a frame, and no accessory exists that would let it. Said at the top and repeated here because it is the thing most likely to rule this out.

• A tray being pushed is a different problem.

  It holds well through ordinary movement — the maker has watched an empty can hold in over forty miles an hour of wind. What a wheelchair tray adds is tilt and a drop over a threshold, and nothing that is not clamped down survives that. If the drink has to travel with the chair, a clamp holder is the right product.

• A handled mug does not seat

  Including the two-handle mugs this aisle sells. The handle lands where the fins grip.

• It does nothing for a hand.

  Not grip, not strength, not steadiness. It is a base on a table, and the glass is exactly as easy or as hard to pick up as it was before.

• It is not spill-proof — nothing is.

  It resists tipping. A hard enough knock moves anything.

—If it turns out to be the wrong thing

Ninety days. Used is fine. Nothing goes back in a box.

It goes on the table and stays there for as long as it takes to know. If the answer is no, hello@steadilabs.com reaches a person and the money comes back — no form, no restocking fee, no questions about its condition, and nothing to pack up or post.

1. You order. Free shipping, every order, always.
2. It leaves Orange, California within one business day.
3. USPS, 2–5 days, tracked.

—Who makes it

Steadi Labs. One person, in Orange, California.

Scott Rodriguez made the first one after a full drink went over on a soft cushion with three kids under three in the house. It was built for spills.

It was not designed as adaptive equipment and it is not sold as any. Nobody asked for this page either. It exists because a wide base does the same thing on any table, and because everything it does not do is written above.

Injection moulded in small runs a few miles from his desk; every order ships from the zip code it was made in. Patent pending. The email address on this page reaches him.
