Desk Height and Height Adjustment
Fixed AODK desks list desktop heights of 29.5-29.92 in where the height is published. The 55 in electric standing desk is the only adjustable one: 29.9 to 46.1 in, per the manufacturer.
Fixed desks
Six fixed desks publish a desktop height, all between 29.5 and 29.92 in. Four don't: on the 48 in, 59 in, 63 in L-shaped and 79 in L-shaped desks the listed height is with the shelf, stand or hutch on top, not the desktop.
Some desks have adjustable foot pads - the 61 in L-shaped gaming desk lists them - which level the desk on an uneven floor rather than change its height.
The standing desk
The 55 in electric standing desk moves from 29.9 to 46.1 in on an electric motor rated 45-55 dB, with 3 memory presets, per the manufacturer. It keeps 2 cloth drawers and a keyboard tray, and its power strip and cable tray move with it.
