Staff can visit the office chair trial room located at 10B lower ground between 8:30am – 5pm, Monday to Friday. Here staff can sit on chairs in various sizes then select a suitable one for ordering through OfficeMax. There is information located in the room on how to choose a new chair and additional information is located below.
A good fitting office chair should offer:
- support along the length of the thighs to within a distance of about a clenched fist from the back of the leg to the front of the chair
- sufficient width to fully support the thighs, ideally with about two cm either side between hips and the side of the chair
- firm fitting support to the low back region
- a well padded, rounded front edge
- firm foam that is not easily compressed
- appropriate weight rating of chair stem for user (note most chairs are weight rated to 110-120kg).
Selecting an office chair
The following guidelines should be followed when selecting an office chair:
- chairs must comply with Australian standards and have the Australasian Furnishing Research and Development Institute (AFRDI) blue tick certification (minimum Level five certification)
- fabric seat and back
- curved front seat edge
- five leg star based with a diameter of not less than 580mm
- adjustable seat height
- consider the dimensions of the workforce when choosing chair seat depth.Smaller framed people will generally require a seat depth of 460mm or less and medium to larger framed people generally require a depth of 480mm or greater. The addition to the chair of a sliding mechanism may increase the number of staff the chair will be a suitable fit for
- seat width should be minimum 480mm
- back rest should be sufficiently padded to provide good low back support,and be adjustable for height and angle
- adjustable controls should be easy to use and access
- arm rests are generally not recommended for primarily PC based work. If they are to be purchased select; adjustable arm rests that are set back from the front edge of the seat and will not impede close access to the desk.
Note: foam on office chairs loses its density over time, at a rate dependent on usage. Old foam will compress more quickly, offer less support and lead to discomfort. Most well rated chairs carry a warranty of five years. It is recommended chairs are replaced every five to ten years dependant on level of; usage and condition. The date of manufacture of chairs can usually be found on the underside of the seat.
Alternate office seating
If a staff member wishes to use an alternate seating option (such as a fit ball, a kneeling chair or a saddle seat) in the office environment, advice should be sought from a medical professional.
Fit balls are generally considered to be unsuitable for office use due to hazards getting on and off, inadequate support for buttocks and thighs, lack of ability to swivel or navigate around the workstation and insufficient support for long periods of sitting to support good trunk posture. If use of a fit ball at work is recommended by a treating medical practitioner as part of an injury management plan, recommendations for duration of use should be supplied.
