Reaching and lifting material that is at waist height is usually considered the "ergonomicaly correct position" from which to lift. However, not all individuals have the same waist level. Wheelchair users may have difficulty accessing materials considered to be "waist height." Also extremely tall, short, and obese individuals can have problems accessing materials at typical waist levels. Reachers, height adjusters, lift tables, work platforms, and adjustable workstations (e.g., industrial and office) are products that can adjust materials so that they may be reached at waist height.
