Wide Height Adjustment Range

Correct elbow angle differs by body, so range decides whether posture is reachable.

Stable at Standing Height

Wobble at full extension makes typing tiring and discourages standing at all.

Smooth, Even Lift Travel

Jerky movement knocks over drinks and makes people stop adjusting altogether.

Soft, Rounded Front Edge

A hard edge digs into forearms during long typing sessions at standing height.

Deep Legroom Under Frame

Crossbars and boxy frames limit knee room and force a twisted seated posture.
