GB Office Chair Standard
The GB office chair standard covers multiple aspects such as dimensions, stability, strength and durability, material safety, and general technical conditions, as detailed below:
Dimension Standard: According to GB/T 3326-2016 'Furniture - Main Dimensions of Desks, Chairs, and Stools' and GB/T 3976-2014, the seat height of adult office chairs should be controlled within the range of 40 to 50 centimeters. This range is designed based on ergonomic principles to accommodate the natural leg bending needs of people of different heights, preventing fatigue or impaired blood circulation caused by improper height.
Stability Standard: Based on GB/T 10357.2-2013 'Furniture Mechanical Properties Test - Part 2: Stability of Chairs and Stools', office chairs must pass stability tests such as forward and side tilting. For example, after loading a specified weight on the front edge of the seat, the front legs must not lift off the ground; during side loading, the chair must not tip over. These tests ensure that the chair remains stable during normal use or minor collisions, reducing safety hazards.
Strength and Durability Standard: According to GB/T 10357.3-2025 'Furniture Mechanical Properties Test - Part 3: Strength and Durability of Chairs and Stools', office chairs must pass dynamic fatigue tests. For example, the seat must withstand tens of thousands of consecutive vertical loads, and the backrest must undergo repeated backward tilting tests to verify its structural strength and resistance to deformation after long-term use. This standard ensures the durability of the chair in high-frequency usage scenarios.
Material Safety Standard: Office chair materials must comply with multiple environmental and safety standards. ABS plastic components must meet GB 28481-2012 'Limit of Harmful Substances in Plastic Furniture', restricting the content of heavy metals such as lead and cadmium; leather materials must comply with GB/T 18599-2018 'Leather for Furniture', controlling the release of formaldehyde and azo dyes; ecological plywood must comply with GB 18580-2017 'Limit of Formaldehyde Emission in Wood-Based Panels and Finished Products for Interior Decoration Materials', ensuring that the formaldehyde emission is below the E1 level standard.
General Technical Conditions: Metal components such as chassis mechanisms must comply with GB/T 3325-2017 'General Technical Conditions for Metal Furniture', specifying requirements for the appearance defects (such as cracks and burrs) of welded and stamped parts, as well as the adhesion and corrosion resistance of the coating. For example, the coating must pass a salt spray test to ensure it does not rust easily in humid environments, extending the service life of metal components.
