Ergonomics is the study of people’s efficiency in their working environment and in recent years it has focussed on office workers and how they sit at their desks. The result has been a huge raft of advice and guidance on ergonomic chairs, seating positions and healthy working practices for those who work at a desk for most of the day. This can be confusing to say the least and can leave you feeling that you need a qualification in anatomy to set up an office chair. Here is a simple guide to setting up office chairs such as Grammer office chairs in five simple steps.
Simple set up check list for Grammer office chairs
Every chair user is different and when you use a chair for the first time there are some simple checks that you should make. It is important that you do them in the order that they are listed here.
- Start with the seat height. When you first sit in the chair, use the lever (or button) to raise the seat to its full height (your legs may be swinging in mid-air at this point!) Carefully lower it until your feet are flat on the floor but your legs are angled forwards.
- Seat depth is important. Sit with your back flat against the back rest of the seat. Some office chairs have a mechanism that allows you to adjust the seat depth by sliding the seat forwards or backwards. If your upper leg length is large (the distance between your pelvis and your knee) you will need a deeper seat. When you make the adjustments you are aiming to have a gap of about 2 inches between the back of your knee joint and the edge of your seat. If you do not have an adjustable seat depth you may need to use a cushion.
- Position the lumbar support. You then need to position the chair back so that the lumbar support fits neatly into the small of your back. Some chairs have additional mechanisms to independently adjust the lumbar support and you can use this to get it into exactly the correct position.
- Move on to the arm rests (if there are any). If the seat has arm rests these should be adjusted so that your shoulder muscles can relax and your lower arms should be at right angles to your body. Fine tune by adjusting the angle if this is a feature.
- Make adjustments to the tilt tension. Some office chairs allow you to adjust the tilt tension to match your build and weight. This enables the chair user to recline with natural support that is not too stiff and not too easy to move when leaning back in the chair. Some office chairs do not have this function.
