Glossary

A safety feature on motorized standing desks that detects obstructions in the path of travel and reverses direction. Implementations vary in sensitivity — premium desks detect a chair arm; budget desks only detect hard impacts.

A cushioned mat designed for standing surfaces. Reduces lower-leg and back fatigue during long standing intervals. Terrain mats (with varied surface contours) outperform flat foam by encouraging active standing.

Business and Institutional Furniture Manufacturers Association — issues standards (e.g. X5.1 for office chairs, X5.5 for desks) covering durability, stability, and structural testing. BIFMA-tested products meet a minimum bar; manufacturers may exceed it.

A monitor arm mechanism that uses a calibrated spring to balance the monitor weight, allowing tool-free repositioning across the entire vertical range. Distinct from gas spring arms, which are cheaper but lose tension over years.

The horizontal beam connecting a standing desk's two legs. Heavier crossbars reduce side-to-side wobble at full height. C-frame, T-frame, and inverted T-frame are the common shapes.

See also: T-Frame, standing-desk, Wobble

Standing desk frame with one motor per leg, synchronized electronically. Required for stable lift under heavy loads (250 lb+) and a prerequisite for serious anti-collision implementations.

See also: single-motor, Anti-Collision

A postural habit where the head sits in front of the shoulders rather than over them. Common with low-monitor setups; correlates with neck and upper-back tension. Raising the monitor so the top of the screen is at or just below eye level is the standard correction.

See also: Monitor Height, posture

A monitor arm mechanism using a sealed cylinder of pressurized gas to counterbalance the monitor weight. Cheaper than constant-force lift; tension drops over 5–10 years and may need re-tensioning.

See also: Constant-Force Lift, Monitor Arm

A keyboard platform that mounts below the desk surface and tilts away from the user (front edge higher than the back). The negative tilt — typically 5–10° — keeps wrists in neutral while typing, reducing flexion strain.

See also: wrist-rest, posture

A backrest feature that fills the curve of the lower spine to maintain neutral lordosis while seated. Quality varies from fixed contours to height-and-depth-adjustable air-bladder systems.

See also: posture, Task Chair

An adjustable mounting system that holds a monitor away from the desk surface using a VESA-pattern bracket. Frees desk space, allows precise height/tilt adjustment, and supports multi-monitor configurations.

See also: VESA, Monitor Stand

The vertical position of the screen relative to the user's eyes. The widely cited ergonomic guideline: the top of the screen should sit at or just below eye level, viewed straight-on or with a slight downward gaze.

See also: Forward Head Posture, Monitor Arm

A fixed riser that elevates a monitor by a single non-adjustable height. Cheaper and simpler than a monitor arm but loses tilt and reach adjustment. Adequate for single-monitor desks with consistent ergonomics.

Herman Miller's lumbar-and-sacral support system, exclusive to Aeron. The newer PostureFit SL adds independent lumbar and sacral pads. Often considered the chair's defining feature.

See also: aeron, Lumbar Support

The cadence of alternating between sitting and standing at a height-adjustable desk. Research suggests roughly 30 minutes seated to 5–15 minutes standing per cycle, but the strongest signal is variation itself rather than a specific ratio.

See also: standing-desk, Anti-Fatigue Mat

A standing desk frame geometry where each leg sits centered under a T-shaped foot. Distinct from C-frames (foot extending toward the back) and inverted T-frames (foot extending toward the front). Affects under-desk clearance and stability characteristics.

See also: Crossbar, Wobble

A height-adjustable office chair with caster wheels designed for desk work. Distinct from executive, conference, or drafting chairs by its emphasis on adjustable ergonomics rather than aesthetics.

See also: Lumbar Support

Video Electronics Standards Association mounting pattern, used to attach monitors to arms, stands, and wall mounts. Common patterns: 75×75 mm (small panels), 100×100 mm (most 24–32" monitors), 200×200 mm (ultrawides and large displays).

Standing desk warranties typically split frame structural coverage from motor and electronics coverage. The longer of the two (often 10–15 years on frame, 2–5 years on motor) tells you the manufacturer's confidence in build quality. Premium brands match both at 10+ years.

Side-to-side or front-to-back oscillation in a standing desk at full height. Correlates with desktop depth, frame design, and load distribution. Measured indirectly by observing how long the desk continues moving after being nudged.
