How the Five Compare on the Numbers
A station that moves asks one question of everything standing on it: what stops it sliding. Four of these five answer that in their own text and the fifth never raises it. The four answers are not even the same kind of claim, and one of them turns out to be about the machine standing on the tray rather than about the tray itself.
The figures are thinner than the claims. Four publish a weight, from 0.15 lb to 1.9 lb, and Tuni publishes none. Only two attach a number to the rim that holds a spill in, and on one of those two the figure is the thickness of the wall rather than its height. Two of the five dimension triples disagree with the size the same maker states.
What the table cannot tell you is how much any of this matters at the speed you work. A non-slip bottom rated against a portafilter being tapped against it is a different promise from a pad that keeps a stand still while you load needles into it, and no maker here publishes a force, a grip rating or a surface the claim was checked against. The claims are words, and the words differ.
What Each Listing Says Keeps It in Place
Three claims about the product itself
Tuni makes the only claim here that involves impact. Its bullet says a non-slip bottom design locks the box in place during use, with no sliding or tipping over when you tap a portafilter against it, and adds that it prevents scuffs on the counter. The box is stainless steel with a removable rubber knock bar the maker says reduces noise and protects the portafilter.
Splash N Color states a stable freestanding base that stays put during operation without sliding, shifting or rattling on any countertop surface. Alvero goes further and ships a separate part for the job: a completely independent non-slip silicone pad, sitting under a magnetic aluminum alloy stand that holds the tool. Two mechanisms in one listing, magnets above and silicone below.
One claim about the machine, and one listing silent
TOHONFOO publishes a non-slip surface too, and its own sentence says what that surface is for: it prevents the coffee machine from sliding due to external forces and ensures the coffee maker is fixed in place. That is a claim about the object on top of the mat, not about the mat on the counter, and reading it the other way round would be the easy mistake on this page.
KEVLANG makes no claim of either kind. Its five bullets cover a spill proof design, smooth edges for safer use, thicker premium acrylic and a long list of other rooms the tray suits. It is also the only pick with handles, named in the product title, which is a different answer to a station that moves: you pick this one up rather than expecting it to stay.
What the Published Figures Add
Weight is the only figure four of them share
The published weights are 0.15 lb for Splash N Color, 0.38 lb for Alvero, 1.01 lb for TOHONFOO and 1.9 lb for KEVLANG, the heaviest of the four that publish one. Tuni publishes none at all, which is awkward here, because a knock box is the one product on this page whose mass is part of the reason it stays where it is put.
Weight also cuts against the claims in one place. Splash N Color is the lightest of the four that publish a weight, at 0.15 lb, and it is the pick that states its base will not slide, shift or rattle. KEVLANG is 1.9 lb and makes no stability claim at all. Mass is not the mechanism either listing is selling, and neither of them says it is.
Only two put a number on the rim
TOHONFOO publishes a raised edge of 0.6 in, written in the listing as a fraction of an inch, around an external 19.7 by 15 in and an internal 19 by 14.5 in. That is the clearest spill geometry on this page, because it gives the figure, the area it bounds and the area left inside it, all in the maker’s own sentences rather than in a field.
KEVLANG publishes 0.19 in as well, and it is a different measurement. The bullet calls it the thickness of the side walls, not their height, so it describes how stiff the wall is rather than how much it can hold back. Reading it as a depth would be wrong, and no height for that wall is published anywhere. The other three publish neither figure.
Where the Published Fields and the Maker Disagree
A size field in centimeters against inch fields
Alvero is the one listing here whose own size field is metric: it reads 9 by 5 by 3 cm. Its dimension fields read 2.1 by 3.3 by 4.2 in. Those are two descriptions of one object and the listing does not reconcile them, so this page states both and judges the stand by what it supplies rather than by how large it is.
The needle figures in that listing belong to the needles and not to the stand: two sets of 304 stainless steel needles at 0.3 mm and 0.4 mm, twenty in all, with four to eight loaded at a time. The portafilter sizes of 51 mm, 54 mm and 58 mm belong to portafilters. Neither set measures the internal catchment groove, which the listing describes and never measures.
A mat that is not a foot thick and a box that really is tall
TOHONFOO fails in the other direction. Its fields read 7.68 by 10.55 by 12.52 in against its own stated 19.7 by 15 in, and a silicone mat is not 12.52 in thick. This page uses the maker’s sentences for that reason. What the fields are describing is not stated anywhere in the listing, and no warning is attached to them in the data.
Tuni is the opposite case: a figure that looks wrong and is not. Its height field of 6 in sits far above the rest of this pool, where nearly everything is a flat tray, and the source data marks it for checking. The maker’s own bullet states 5.5 in wide and 6 in high, so the field is right and the pool is what makes it look strange.
Which One Fits Your Kitchen
The barista who taps a portafilter hard. Tuni is the only pick whose stability claim covers impact, saying the non-slip bottom stops sliding or tipping when you knock a portafilter against it. Stainless steel, 5.5 in wide and 6 in high, with no weight published.
The one who wants the holding part supplied separately. Alvero ships an independent non-slip silicone pad under a magnetic stand, at 0.38 lb. Its size field reads 9 by 5 by 3 cm while its dimension fields read 2.1 by 3.3 by 4.2 in, so measure the space yourself.
The one with a grinder and a small gap under it. Splash N Color publishes 8.7 by 4.9 by 1 in at 0.15 lb, the lightest of the four that publish a weight, and states a freestanding base that will not slide, shift or rattle. A damp cloth is the only cleaning route it names.
The one catching liquid rather than grounds. TOHONFOO publishes 19.7 by 15 in outside, 19 by 14.5 in inside and a raised edge of 0.6 in, at 1.01 lb. Its non-slip claim is about holding the machine, so the mat itself is not what is being promised.
The one who carries the tray to the table. KEVLANG is the only pick with handles and the only one making no stability claim. It publishes 20 by 12 by 2 in, side walls of 0.19 in thickness and 1.9 lb, in acrylic, and names no washing method.
What We Could Not Verify
Everything above comes from the makers’ own listings. These are the things those listings do not answer.
- Any measured basis for a non-slip claim. Four of these five make one and none publishes a force, a grip figure or the surface it was checked against.
- A weight for Tuni, the one product here that gets struck in normal use, and the one whose mass would matter most.
- A height for the KEVLANG side wall. The 0.19 in figure its bullet gives is the thickness of that wall, not its depth.
- What the TOHONFOO fields of 7.68 by 10.55 by 12.52 in describe, given that the same listing publishes 19.7 by 15 in.
- Any size for the Alvero catchment groove, which the listing describes in words and never measures.
- A washing method from Alvero. Its bullets talk about keeping the workspace spotless and never say how to clean the stand or the pad.
