Collection: Heavy Duty Office Chairs

High-Capacity Seating for Demanding Environments

Learn more

Heavy duty office chairs are designed for weight capacities above the standard 110 kg rating. They feature reinforced steel frames, wider seat pans, heavier-duty gas cylinders, and commercial-grade casters rated for higher loads. Many carry AFRDI Level 6 certification, which is the Australian standard for chairs tested under sustained heavy commercial use conditions.

These chairs are suited to industrial environments, healthcare and government facilities, public-access workspaces, and any setting where a wider range of users will be using the same chair across shifts.

For buyers who also need floor protection under heavier seating, chair mats rated for commercial use are available. For standard ergonomic seating without the heavy-duty specification, see ergonomic office chairs.

Frequently Asked Questions

Have questions about this office furniture collection? Here are some answers to help. If you need anything further, our team is here to help.

Heavy duty office chairs are typically rated for capacities ranging from 120 kg to 200 kg depending on the model. Standard commercial chairs are rated to approximately 110 kg. Always check the manufacturer's stated weight capacity for the specific chair before purchase. Exceeding the rated weight capacity reduces structural integrity and voids most warranties.

Heavy duty office chairs are suited to industrial workplaces, government service counters, healthcare facilities, call centres, and any environment where chairs are used continuously across multiple shifts or by users requiring a higher weight capacity. They are also appropriate for any commercial setting where chairs receive heavier daily use than a standard open-plan office.

AFRDI certification is not legally required but is strongly recommended for heavy duty chairs used in commercial, government, education, or healthcare environments. AFRDI Level 6 certification confirms the chair has been independently tested for structural performance under sustained heavy use. Some government and institutional procurement frameworks require AFRDI certification as a minimum specification.
