This standard outlines the material, dimensional, and constructional requirements for metal revolving and tilting chairs used in offices. It provides specific guidelines for the pedestal base, tilting mechanisms, fabrication quality, finishes, and mandatory performance testing to ensure safety, durability, and ergonomic function.
metal chairs for office purposes Specification, Part 2: Revolving and tilting (BI-LINGUAL)
Quick Reference Values
adjustable seat height range430 mm to 530 mm
minimum width of seat450 mm

Practical Notes
Modern office safety requirements highly recommend a 5-prong base (star base) to prevent toppling backward when the chair is fully tilted.
During procurement, insist on durability test certificates specifically for the gas lift mechanism and spring tension adjustment.
Welds and joints must be thoroughly ground and finished; sharp edges are a common cause of failure in quality control due to potential injury or clothing damage.
