Drafting chairs were originally designed for use by architects and engineers, who need to sit for long hours at an end at drafting tables in order to come up with plans and sketches. Eventually, however, the use of drafting chairs were extended to other people who are also required to be on their chairs for long durations so they could work, such as secretaries, writers, data-entry workers and such.
Good drafting chairs are always designed with ergonomics in mind. Ergonomics, also called human engineering or biotechnology, is an application of scientific knowledge in the workplace. In ergonomics, the aim is to increase workers' productivity and at the same time minimize the injuries sustained by these workers' bodies in the execution of their work.
Ergonomics is a catch phrase in offices nowadays, and those who want to sell office and industrial furniture are sure to tag the word "ergonomics" to their products just so they could sell more briskly. So, the drafting chairs you may end up buying may not exactly conform to ergonomic standards. It is therefore important to examine the drafting chairs you would purchase before shelling out the cash to see if they really are ergonomic.
What should you look for when buying drafting chairs? The first thing that you should take note of when you are in the market for drafting chairs is that they should be comfortable. If the body is comfortable sitting on the chair despite working for long hours, the chances for sustaining work-related injuries are minimized. The chair will provide ample support for the muscles of the back, the arms and the legs, and will not hamper the circulation of blood in the body.
The drafting chairs that you should buy should also have ample room for the girth of the body. If it pinches at the hips, you should then look for a bigger one. Drafting chairs should be of the right size for your body so it would be comfortable and the flow of blood inside the body will not be hindered.
When purchasing drafting chairs, you should see to it that they are adjustable to fit the length of the leg and the height of the arms. They should also have foot rings. When sitting, the feet should remain flat, whether on the floor or on a raised platform. This is supposed to keep the blood circulation going unhampered in the body. The arms should also be parallel to the ground to prevent the development of carpal tunnel syndrome.
Good drafting chairs also have ample cushioning on the end for supporting the knees, on the curve for the small of the back, and on the seat itself for supporting the weight of the person sitting on it. The cushioning in drafting chairs is important because it prevents the muscles from going sore because of sitting down for so long, particularly for the lower back and the buttocks. The padding on the end of the chair is supposed to prevent the back of the knees from getting pinched, which would prevent the blood from flowing freely through the body.
Other features that you can look at when buying drafting chairs are its recline and tilt, as well as the seat pan angling.
Choose your drafting chairs wisely not just so you could get a good buy, but also to protect your body from work-related injuries.
