This report describes results for a study of electric height-adjustable worksurfaces (EHAWs) conducted in two companies. A total of 33 computer workers from the two companies worked at fixed-height worksurfaces (FHWs) and then at EHAWs for between 4 and 6 weeks.
Participants completed extensive survey questionnaires immediately before and then 4-6 weeks after using the EHAWs. Results showed significant decreases in the severity of musculoskeletal discomfort for most upper body regions.
In the EHAW condition daily discomfort ratings were lower in the afternoon and productivity ratings improved. Written comments about the EHAWs generally were positive. There was a strong preference for using the EHAWs. Implications are discussed.
