Finally, somewhere to put your drink in the bay.
4.9 from 119 Steadi reviewsA flexible-finned base that holds your coffee or energy drink steady on the roll cab, the bench, the cart, or bare concrete — no magnet, no clamp, nothing to bolt on. It moves with the job, not with the box.
Add to the bay — $14.95One flexible piece, nothing to snap or unclip — rinse it clean, and 90 days to prove it wrong if it doesn't earn a spot in your bay.
Will your travel tumbler fit? One sticky note off the service desk answers it ↓
Any of this ring true
You already know these jobs.
You roll out from under the car and your elbow finds the coffee you set on the concrete when you slid in — it's sliding across the slab and soaking into your shirt before you're even upright.
Pushing the service cart to the next job with a full cup riding the tray — every expansion joint in the floor sloshes it, and by the third bay there's a puddle pooled around the socket rail.
The gas-station coffee goes on the fender cover so both hands are free for the caliper bolt. The pull rocks the car, and the cup skates down the vinyl and off the paint.
Reaching across the roll cab top for the torque wrench, a sleeve catches the open tallboy — it drains into the top drawer, over the combination wrenches, right as you're closing out the job.
Working standing with both hands overhead, the drink is wherever it landed — a lift-post ledge or the floor by the wheels. By the time the car comes down, it's cold and wearing a film of shop dust.
Plain mechanics
No hardware, no install, no torque spec.
A slid ratchet or a shoved cart can tip anything standing on a single point of contact. The wide, low base lies flat across the surface instead, painted steel or bare concrete alike.
Flexible fins hold the drink by its bottom inch, so the vibration off a grinder or an impact gun can't walk it toward the edge.
A bumped elbow, a dragged air hose, a cart rolled over an expansion joint — the base's low, wide weight rocks with the knock and brings the drink back level.
Why it earns space
Three reasons it earns bench space.
Grips painted steel the same as concrete
The wide, low base spreads its footprint across whatever's underneath instead of standing on one point — roll cab lid, workbench, cart top, or bare floor. Hard, flat surfaces are exactly what it's built for; no magnet, no clamp, no lip required.
Holds what actually rides in a bay
The gas-station coffee, the energy-drink tallboy, the 40 oz tumbler, the bottle off the parts run. Cans and bottles slide right on; cups and tumblers drop through the fins and get held by the bottom inch, right where vibration would otherwise walk them loose.
Moves with the job, not with the box
One piece of flexible material, nothing bolted or clipped to a single drawer lip or one brand's stacking system. It rides on the roll cab this job, the bench the next, and stows flat in a drawer when the shift's over.
The 10-second check
The whole fit test is one sticky note off the pad.
lands in here
A square sticky note: 3 inches, exactly — the same ceiling as the fit range.
The classic square is exactly 3 inches on a side — a fact about sticky notes, and it happens to land right at the ceiling of what fits.
Stand it on the note on the bench, not balanced on the rim. A tapered tumbler or a flared fountain cup lies about its true size — the bottom is the only measurement that counts.
Base sits inside the square? It fits. Hangs over the edge? Too wide. A tiny puck lost in the middle — under 2 inches? Too narrow.
No calipers, no spec sheet, no guessing between jobs. One sticky note off the pad on the bench, one glance, with the cup you actually bring into the bay.
The fit question
Go by the base, like everything else in the bay.
One rule covers the whole list: a container base 2 to 3 inches across settles in. Everything below follows from it.
- Gas-station coffee cup fits
- 16 oz energy-drink tallboy fits
- 40 oz Stanley-style tumbler fits
- 20-30 oz stainless tumbler fits
- Standard 12 oz can fits
- Disposable 16.9 oz water bottle fits
- 28-32 oz sports bottle fits
- Protein shaker bottle fits
- Break-room coffee mug, handled handle in the way
- Fountain drink, Big Gulp-size too wide
- Paper espresso cup too narrow
There's a floor as well as a ceiling — under 2 inches the base sits too loose. The break-room coffee mug is the honest exception: the base itself fits, but the handle lands right where a fin needs to grip.

Versus what you do now
Compared to what's already bolted to your box.
| A magnetic toolbox cup holder | The Mechanic's Cup Holder | |
|---|---|---|
| On the wood bench or bare concrete | Needs bare steel to grip anything | Holds steady on wood or concrete too |
| Set down fast, not dead level | Slides off if it's not square | Settles in, angle and all |
| A full 40 oz tumbler | Sized for a can, rides top-heavy | Holds steady, same as a can |
| Moving it from bay to bay | Fixed to whichever box it's stuck to | Moves with you, nothing to unclip |
| Mounted under the two-post lift | Built to clip onto the lift post | No flat spot up there, set it on the cart instead |
| Space on top of the roll cab | Rides the side, keeps the lid clear | Sits on the lid, needs its own spot |
| Cost | Another accessory bolted to one box | One small piece that goes wherever you do |
A steel cup on rubber-coated magnets that clips to the side of a box or cart. Users report it slides off unless it's set down dead level, it's sized more for a can than a tall tumbler, and it only holds on to bare ferrous steel — useless on the workbench, the car, or the floor where the actual work happens.
Snaps into a specific stacking system rather than sitting wherever your hands are. Reviewers ask for taller sizes than what's offered, and the insulated version draws reports of leaking, a lid that breaks on a short fall, and not fitting most truck cup holders.
Hooks over one specific box lip or drawer edge — a popular design fits about one-eighth inch of lip and nothing thicker, so what fits one box doesn't fit the next. It's tied to that one drawer, not portable to the bench or the floor, and it's printed plastic living next to brake clean and impact tools.
The default. Sloped, slick sheet metal, a cluttered steel top, and ankle-height concrete are three of the worst places a cup can sit — and trusting one of them is exactly what produces the elbow-knock, the drawer flood, and the creeper-roll spill.
From the reviews
What buyers say.
Recent reviews of the Steadi, from every room and rig it lives in.
I have a tendency to spill my drinks and have two cats. This is one of the best things I’ve ever impulse bought. It works. It actually works. It’s a heavy, wide enough base that it is actually stable. My “spot” in the living room is near a somewhat-cushioned fabric ottoman, which is where I usually put my drinks. It’s
Dixie · 2026-08-30I love mine. I just wish the price was more appropriate. $15 seems a lot for a small plastic item. Reduce it to $9.99 and free shipping and I'll buy a few more!
Carolyn G. · 2026-08-27Excellent!

Why more than one
Two identical tallboys. Whose is whose?
Two techs pull the same energy drink from the same case, and now there are two identical cans sitting on the roll cab lid. Nothing about them says whose is whose until somebody's already had a sip off the wrong one. Give each one its own base and the color settles it before your hand does.
Build your set
Give everyone their own.
Pick a pack, then give each one a color — so nobody has to ask which drink is theirs.
Worth knowing
Asked over the fender, answered here.
Does it actually work on a roll cab or bare concrete?
That's exactly the surface it's built for. Hard, flat ground is where the wide base and the fin grip do their best work — it holds steady on painted steel, concrete, or a workbench at least as well as it does anywhere else, no magnet or clamp involved. Bump it and it settles back instead of walking toward the edge.
My toolbox isn't steel — does that matter?
No. It doesn't rely on a magnet, so it works the same on a wood bench, a painted fender, a plastic cart, or the shop floor. Ferrous or not, flat is all it needs.
Will my 40 oz tumbler fit?
Measure the bottom, not the rim. A base of 2 to 3 inches across settles in — the 40 oz Stanley does. A handled coffee mug doesn't; the handle lands where a fin needs to grip.
Does it clamp or bolt to my box or cart?
No. Nothing clips to a drawer lip, bolts to a frame, or sticks to anything. It sits on top of whatever's flat and moves with you from bay to bay.
What about vibration from the impact gun or a bench grinder?
That's the everyday case it's built around. The base rocks low and wide and resettles the drink when a tool or a cart shoves it — it resists tipping, not a direct hard hit, but the steady shake of shop work is exactly what it shrugs off.
Can it ride on the service cart while I move between bays?
Yes — it holds on the cart top the same way it does on the bench or the roll cab, so crossing expansion joints and thresholds doesn't send the drink sliding into the tray lip.
What happens when the car's up on the two-post lift?
Nothing about this magnets or clamps on, so it doesn't ride the lift post the way an aftermarket magnetic holder can — it needs a flat spot to rest on, and there isn't one up there. Set it on the nearby cart, the bench, or the floor by the post instead of chasing a spot at working height.
How do I clean brake dust and grease off it?
Rinse it, wipe it down, or put it in the dishwasher. It's one piece of flexible material with nothing to trap grit or come apart.
Who makes it, and where do I buy one?
