Cheaper in Home office, and what changes
Things of the same kind for at least 10% less than $167.99, with the attributes the retailers describe differently. Their words, not our judgement: we compare listings, we do not test products.
Micom Laboratories, a testing lab, describes ANSI/BIFMA X5.1 as the standard giving manufacturers, specifiers and users a common basis to evaluate the safety, durability and structural adequacy of general-purpose office chairs. It says the 2017 edition has 20 tests and that not all tests need to be done on all chairs; which tests apply depends on the chair type (tilting, fixed seat angle with tilting backrest, or fixed seat angle with fixed backrest).
Micom says X5.11 is for occupants with a mass greater than 253 lb and up to 400 lb, adds a minimum seat width for a “Large Occupant Chair”, and increases most of the loads and forces. It adds that X5.11 is not a bariatric chair standard, so chairs tested to it cannot be qualified as “bariatric”.
