An increasing percentage of the population is spending longer and longer periods of time in seated postures. There is clear evidence that longer exposures to seated postures are linked with higher rates of reported low back pain. This association between low back pain and prolonged seated office and industrial work has driven preventative strategies that involve alternating standing and sitting postures. The strategy of alternating sit and stand while working has been shown to reduce perceived low back pain and have minimal impact on work efficiency. To accommodate this change in postures a variable height work surface is required, referred to as sit to stand workstations. Current technology prevents these workstations from meeting ergonomic standards of user height accommodation, leg clearance and reach envelopes. The goal of this research partnership is to incorporate current research on the prevention of injuries during prolonged standing and seated work and
