An electric standing desk moves for a few seconds at a time, a few times a day. That makes it one of the least important noise sources in a home office, and one of the most heavily marketed on quietness. We checked what the makers actually publish.
We read product pages and specification sheets for twenty one desks and frames from nine brands. Seven brands publish a decibel figure. The figures run from <30 dB to < 55db, and almost all of them are ceilings with nothing attached.
Our 7 picks are listed above, with full specifications for each.
A ceiling is not a reading
<48 dB. <50dB. "lower than 45dB". That is the form nearly every figure in this category takes: a number the desk should not exceed, with no load on it, no distance to the microphone, and no direction of travel.
A ceiling is a promise about the worst case, which is useful. But a ceiling from one brand cannot be lined up against a ceiling from another, because neither says what was tested. For the general problem, see why you cannot compare dB ratings across brands.
Two makers give you slightly more. Fezibo attaches the words "maximum operation" to its figure, which at least names a state. Autonomous, for its L shaped desk, publishes "50 dB at the loudest point in the lift", which is a reading with a condition and the only one in this guide.
Flexispot publishes a range, in the wrong place
Flexispot is the only maker here that publishes a range rather than a single number: "The noise emitted by the FlexiSpot E7 Pro standing desk lies between 34 to 46 dB". A range is more honest than a ceiling, because it admits the number moves.
It lives in a blog post comparing the E7 Pro with an Uplift V2. The E7 Pro product page carries no decibel figure at all, and neither does the E7's. So the most informative Flexispot figure is the one a buyer reading the specification will never see.
Where a number is on a document
Uplift is the only maker here that puts its figure on a numbered specification sheet, "Noise Level <48 dB" on sheet SP-FV3-200T-1.1, next to the travel speed and the lifting capacity. That is not a test standard, and it still has no condition attached, but it is a document you can cite and check later.
Uplift's older sheets show the figure moving. The V2 Commercial sheet gives "50 dB" as a reading; the V3 sheet gives <48 dB as a ceiling. Same maker, two generations, two kinds of number.
Autonomous publishes "Noise level <30 dB" for the Desk Pro. That is 15 dB below every other maker's figure in this guide, with no condition attached and no explanation of what makes the desk that much quieter than its own Desk Core at <=50 dB.
We have recorded it as published and kept it out of the table. A figure that far from everyone else's, with nothing to support it, is not one we would buy on.
More motors, not less noise
The intuition is that a dual motor frame is quieter because each motor works less. Vivo's own range says otherwise: its single motor V102E is rated <50dB, its dual motor V122EB is rated < 55db.
Dual motors buy you lift capacity and speed. The Uplift V3 moves at 2 inches per second with 355 lbs on it; the single motor Autonomous Desk Core moves at 1 inch per second with 176 lbs. Neither figure tells you which one is quieter at your load, because nobody publishes a figure at a load.
Who publishes nothing
Vari says "whisper-quiet" on its product pages and its specification sheets, and prints no number. Branch describes "low-decibel motors" without saying how many decibels. IKEA publishes nothing for the Mittzon, and its US Trotten is a hand crank. SHW publishes nothing on its own site.
We did not measure any of these desks. Every figure here is the maker's own, quoted as published, with the condition attached in the rare case where the maker attached one.
