How Electric Height-Adjustable Desks Work
A motor built into one or both legs drives a telescoping column up or down, moving the whole desktop between a published lowest and highest setting. Those two numbers are hard limits, not suggestions - the desk cannot go beyond either one, which is the entire basis for the height-fit checks on this site.
What moves, and what doesn't
The desktop itself does not change shape or size - it is the legs that move, telescoping on an electric motor to raise or lower the whole surface as one flat plane. Every desk in this range uses this motorized lift rather than a hand crank or a pneumatic gas-spring mechanism, which is what makes the adjustment electric rather than manual in the first place.
Why the range has a real ceiling and floor
The telescoping column can only extend so far before running out of travel, and it can only retract so far before the sections run out of room to nest inside each other. Those two physical limits are exactly the published lowest and highest settings - not a marketing range, but the actual mechanical travel of the legs. A desk cannot be coaxed past either number by adjusting anything else.
Why that makes the height check different from a footprint check
A desktop that is a little too narrow can sometimes still work with a slightly cramped setup. A desk that will not go high enough to stand at, or low enough to sit at, simply does not do the thing it was bought for - there is no partial version of the wrong height. See the sizing pages for how each desk's published range converts into the heights it actually suits.
What isn't confirmed here
Whether a specific listing includes memory-preset buttons, collision detection, or a particular lift speed is not stated consistently across this range's titles or the data this site draws from - check the individual listing's own bullet points for those features rather than assuming they match across models.
Questions
Can the motor be adjusted to go higher or lower than the published range?
No - the published lowest and highest settings are the physical limits of the telescoping legs, not a conservative estimate with room to spare.
Is the lift mechanism the same across every desk in the range?
Every desk here uses an electric motorized leg lift rather than a manual crank - beyond that, details like lift speed or memory presets are not stated consistently across listings.
Why does this site check height range before footprint?
A desk that never reaches the right height is unusable regardless of how well it fits the wall. Footprint is still checked - see measuring your wall or corner - but it is the second question, not the first.
Does the motor need a special outlet?
No - see cable and power management for what a standard installation actually needs.
