CUSTOM ADAPTATION PURPOSE: To enable an individual with short stature to sit comfortably at her desk. A commercially-available swiveling desk chair was purchased and virtually rebuilt. The seat was removed from its existing base and mounted on a custom-built parallelogram-shaped base which was attached to a screwjack to raise and lower the chair height while keeping the seat horizontal. The screwjack was powered by a 50-watt direct-current (DC) motor. This enabled the user to sit on the chair at its lowest height and then raise it to standard desk height. The arrangement retained the chair's original swivel capability. The seat, lifting mechanism, and motor were then remounted on the original reworked base with casters to retain mobility. A narrow wooden footrest was hung from metal bars below the seat. POWER: Uses a motorbike battery. TITLE: Sitting Comfortably. JOURNAL: TAD Journal. REF: Volume 27, Number 1, May 2007: p. 17-18.
