Current chair testing protocols called for in USA industry standards from BIFMA/ANSI are based on criteria that is decades old, and does not include the effects of modern computer based office work, nor the significant trend of increasing weight among the adult working population. Texas A&M researchers Benden, Fink and Congleton conducted an in situ study of user habits that affect office chair design (in situ -- meaning they tested participants in actual chair use in real office conditions). Based on their results, the authors provide specific recommendations for updating existing testing standards, and for developing new standards specifically for emerging Heavy Duty and Bariatric Office Seating standards.
