Overview
- A yearlong study of more than 10,000 office workers found employees using height-adjustable sit-stand desks averaged 3.66 hours of active computer time per day versus 2.95 hours for fixed-desk users, a gap of about 43 minutes.
- The research paired employee comfort surveys with objective digital tracking of keystrokes, words typed, mouse activity and typing errors to measure engagement and output.
- Using the extra roughly 171 hours per year and a standardized $52 hourly rate, the authors calculated about $9,000 in potential annual productivity value per employee, a figure that depends on the wage assumption and task type.
- The study was observational and not randomized, so researchers warn selection bias is possible because employees chose whether to use sit-stand desks as part of a company program.
- Authors frame the result as evidence of a broader 'workplace effect' where physical design affects health and performance and they call for follow-up work to test causation, generalize findings across jobs, and explore how AI tools might change those links.
