Principles of Ergonomics Office Chair

Principles of Ergonomics Office Chair

December 17, 2008

The principles of ergonomics are used with office chairs to give you comfort and safety. Below, you’ll find some key points to look for in an office chair.

The height of an office chair should always be easy to adjust. In order to do this, the chair must be equipped with a pneumatic adjustment lever. This lever should be able to move your chair between 16 and 21 inches off the floor. The chair shouldn’t be too high or too low, so the user doesn’t slouch or strain at their desk. The important thing to remember is that the knees should be at a lower height than your hips. This will encourage the natural “double C” of the spine and help to provide upright support for your body.

An office chair should always be wide enough to support users of all shapes and sizes. Normally, the width will vary between 17 and 20 inches. The chair depth area is the area found from the front of the seat to the back of the chair. The depth of the office chair should be big enough for you to lean back against the backrest with 2 to 4 inches difference between your knees and the seat of the chair.

Armrests are adjustable and will allow you to rest your elbows, arms, and shoulders in a comfortable manner. The backrest on an office chair will vary from 12 to 19 inches. Like all other parts of office chairs, the backrest should be adjustable enough to move either forwards of backwards. Working in an office requires you moving about, from one computer to another or even to a file cabinet.

Popular Mesh Back Office Chairs

December 11, 2008

A majority of people are concerned that mesh back chairs don’t offer the support that a normal office chair will offer. All mesh chairs have lumbar back support built right in and are designed for support and comfort. A regular office chair can make this worse, as it will cut off the airflow to your back, causing your body temperature to rise. Mesh back office chairs prevent this by allowing your back room to breathe. The mesh material allows for the exchange of air through the chair, making your day at the office less stuffy. You can spend hours and hours in a mesh chair and your back won’t even know it.

Another reason for the popularity of mesh back office chairs is their design. By offering a contemporary design, the mesh back chair lets your clients know that you are up to speed with your office. You can even get your own design and material, customizing your chairs the way you want. Vendors and retailers give you the chance to customize your mesh back chairs, allowing you to blend them in with your conference room. You can turn your conference room or office into a work of art with mesh back office chairs.

Executive office chair, Heavy use chair and Moderate use chair: Which is the Ideal one?

November 29, 2008

For the average security, an office chair that offers the ultimate in comfort is an ideal purchase. You can purchase a heavy use chair, as you’ll probably spend a good amount of time at a desk. Before buying an office chair, there are a few questions that you should ask yourself. Almost all office chairs come with a variety of mechanisms that will control the tilting angle, tension tightness, and a mixture of other controls as well.

Executive office chair
These types of office chairs normally have the same types of mechanical features as moderate use chairs, although they are normally larger, more comfortable, and offer more style for the executive. Comfort, style, and status are the key features when buying one of these types of office chairs.

Heavy use chair
These types of chairs are for those who plan to sitting at their desk for long periods of time. If this is your profession, you should look for a chair with a tilting mechanism and also a fatigue reducing device on the bottom of the chair seat. Because of this device, moving forward or backward will enable the chair move with you in order to provide support.

Moderate use chair
If you are a typical assistant manager or run back and forth between your desk and other areas throughout the day, you should consider getting an office chair with a knee-tilt mechanism. This allows you to lean back in the chair, yet still keep your feet firmly planted on the ground. Chairs that don’t have this will typically lift your feet when you lean back and fort, which can ultimately lead to discomfort over time. Best of all, these chairs are normally more stylish than the average task chair.

Adjust Your Office Chair

November 21, 2008

In most situations, and especially where your job requires you to sit in your chair for an extended period of time, your backrest will need to have an adjustable height so that you can get the maximum amount of support for your back. There are some backrests that can even be moved forward or backwards. If the seat pan is deep, these features can be even more useful. Whatever you do, never sit in a chair for a long period of time without back support. You should adjust the height of the chair so that your feet are able to rest comfortably on the floor, with your thighs horizontal. If your feet cannot rest on the floor, you’ll need a footrest.

If your office chair has a pneumatic level, height adjustment can be accomplished from a seated position. In order to raise or lower the height of older office chairs, you’ll need to stand in front and rotate the seat clockwise or counter clockwise. You’ll know the height is right when the height of the seat pan is just below the height of your knee caps. You should always avoid situations where your feet dangle, as this will compress the tissue on the back of your thighs and behind your knees, also leading to aches and discomfort in the lower legs. There should be a space about the width of a clenched fist between the back of the knees and front of the chair.

If there isn’t, lower the chair slightly. If the chair has the ability, tilt the seat pan forward to slightly relieve the pressure. You may need a foot rest. The rounded edge on many office chairs will also help to prevent uncomfortable pressure behind the knees. At your desk, your office chair should be adjusted to accommodate the working surface. What this means, is that your chair should be raised high enough to keep your sitting comfortably at your desk.
