Following our recent blog post ‘chairs for thought’, we promised to discuss some additional features with office chairs because to promote good posture at work it’s important to have appropriate adjustability options to ensure the chair fits the user correctly. So here’s a little information on armrests and seats:

Armrests

It’s surprising how many people develop muscle stress from a poor ergonomic set up. Sometimes conventional seating solutions provide height adjustable armrests however multifunctional armrests not only help provide the arm support you need at your workstation, they allow fine tuning to ensure that the support is extremely adjustable.

What do multi-functional armrests do?

Although some office chairs offer ‘basic’ armrests, we normally recommend 3D or 4D featured armrests to enhance our ergonomic seating solutions. 3D armrests offer the flexibility to adjust the height, width and depth of your armrests while 4D offers height, depth, width and locking twist features.

Human Factor claims seemingly that:

‘unsupported arms can result in up to 80% more effort – leading to tendonitis in the wrist, strain in the shoulders and upper back aches and pains’

A good reason to have fully adjustable armrests!

You should however make sure that if your chair features armrests, they are not restrictive by preventing you from getting sufficiently close to your desk and in turn causing unnecessary stretching – i.e. encouraging movements well outside of your ‘easy reach zone’.

Seat Pans

Seat Slide AKA Depth-Adjustable Seating

Seat PanAll of our ergonomic seating’ range provide around a 5 cm sliding seat. A depth-adjustable seat not only accommodates the longer or shorter femur length user, but can also provide additional support for the thighs and also help to prevent possible leg restriction occasioned by the front of the seat. Many ergonomic seat pan solutions also offer a shaped ‘waterfall’ leading seat edge. But it’s not just the seat slide that is important…

…it’s the size of the seat! Perhaps you need a short, long/deep, wide or narrow seat pan? When choosing an office chair, you’ll need to consider your body measurements, based on your physical size and shape. Human factors provide a great Body Shape Assessment to help you consider your needs based on anthropometric and somatometric measurements.
