What Is An Ergonomic Office Chair?

What Is An Ergonomic Office Chair?

by Owen Jones

Before you go out and purchase a chair for your office because you like the look of it, you should realize that not all chairs are equal. An office chair should be seen as a piece of health and safety apparatus, although that does not mean that it does cannot be attractive too. I will explain what you should look for in an office chair over the next few paragraphs.

The most essential feature of any chair that you will have to use for a protracted interval of time is the height of the seat itself off the floor. You most comfortable long-term seated posture is with your thighs parallel to the floor and your feet flat on the floor. If you cannot find a chair to fit your proportions or if the chair will be used by various people, then you will have to obtain an adjustable one.

The chair should be adjustable while you are sitting on it in order to ensure that you get it correct. The old fashioned method was to wind the seat up or down on a screw by spinning it round and round. The modern method is to pump it up hydraulically.

There has to be a back to the seat, a stool is no good for long term seating. The back rest should include a lumber support. This lumber support should be adjustable too. It must go up and down, but some can be blown up as well. The back rest should also extend to the head, if it does not suit, then there should be an adaptable head rest. Often there is a tilt mechanism, which allows the sitter to adopt different postures for short periods of time.

This is a feature of chairs known as recliners. If you go for a recliner, make sure that the base is stable, so that you do not go over. A five-pronged star shaped base is the most common design, but there are others too. The base is usually on five casters to preclude the need to stretch and lean, if you have to get to a near-by filing cabinet.

The seat or the seat pan is important. These are adjustable on some more expensive chairs, but it is better to test these features 'for fit' on those that are not. The leading edge of the seat should be rounded so as not to hinder your circulation. For the same reason, there should be a suitable gap between the leading edge and the back of your knees.

The seat should be at a comfortable incline, one that suits you. Most chairs have seat pans that are parallel to the floor, which suits most people, but a reclining chair fixes this problem automatically, as they recline forwards and backwards. The fabric of the seat should be one that breathes and is comfortable. This is one of the reasons why leather is favoured. It should also be padded and easily cleanable.

While not absolutely necessary, arm rests can be useful for reading or taking a few minutes rest. Good arm rests will be height (and some even width) adaptable. With your arms by your sides, the arm rests should reach your elbows.

These suggestions are given in order to reduce the possibility of strain and injury to those who spend many hours at a time working at a desk.
