Mesh chairs
Choosing a mesh chair for your workstation? Check that it meets the minimum ergonomic requirements for your body and workstation.
These requirements apply to all mesh task chairs used at Monash's Australian campuses.
General requirements
You need to purchase all new chairs through approved suppliers. Chairs must:
- meet Australian/New Zealand Standard AS/NZS 4438:1997 for height-adjustable swivel chairs
- have Australasian Furnishing Research and Development Institute (AFRDI) Level 6 certification.
Functional requirements
Lumbar support
Your chair needs to provide proper lower back support, either:
- built into the mesh design, or
- through an easy-to-use adapter.
Backrest width
The backrest needs to be wide enough to allow full elbow movement at lower back height.
Contact and support
When you adjust the backrest vertically for desk work, your lower back should be the main contact point. You shouldn't feel pushed forward at your mid-back or shoulders.
Size considerations
If you're purchasing mesh chairs, consider smaller sizes and additional adjustment options for people who are shorter or have specific needs.
Adjustment mechanisms
Your chair's adjustment mechanisms need to let you lock the backrest upright, and ideally in other positions, for different tasks.
Free-float option
If your chair has a free-float backrest:
- it needs to be easy to adjust and have adjustable tension to suit your weight
- the seat should move with the backrest to keep you stable.
What else you need to know
Mesh fabric doesn't provide much insulation, so you might feel cold in air-conditioned or open-plan offices.
