When you think of railroads, I'll bet office chairs don't come to mind. You may not think that railroads and office chairs have anything in common, but historically, the creation of the office chair links back to the arrival of the railway in the mid-1800s. Of course the focus on the ergonomics of office chairs in those days were minimal, but the idea that the office chair would increase productivity and accessibility spans over the centuries. Most work pre-railway was manual labor and farming - almost 90% of the civilian work force were farmers - but with the railway came a change in labor.
The railway created an expansion of family businesses into larger, more corporate services. With the boom in the business realm, administrative work became essential, introducing jobs like accounting, bookkeeping, and correspondence. Designed to increase productivity of clerical employees in the 1800s, the purpose of the office chair hasn't changed much since. Also, because technology was also booming, office equipment became important for the first time. Employees were expected to sit and work long hours - much like we are expected to do now. Comfort became a key factor, and office chairs began to develop as professions did in the 19th century. Chairs began to be made with wood saddle swivel seats, slatted backs, and armrests.
In the 1970s, an important factor was added to the design of the office chair, with emphasis on ergonomics. Today, we realize more and more how important comfort and support is in an office chair, especially with how much time we spend sitting at work. Most office chairs also have wheels, making moving around easier and faster. Office chairs are now constructed so that an individual can adjust the seat height and tilt, armrests, and chair back. All office chairs should provide proper lumbar support. Back, neck, and shoulder pain are serious issues in the workplace, making it vital that employees are smart about choosing an office chair that fully supports them, and that their office chair is individualized to meet their body's needs. Your individual weight, height and dimensions are important when investing in an office chair.
Each body is unique and today's office chair construction takes that into consideration. Leather office chairs are comfortable, durable, and easy to clean. Others might prefer office chairs with different fabrics, which are sometimes easier on the wallet, but still give great support. Drafting chairs are also a wonderful choice for architects and artists and other people who have professions that involve higher desks than the normal ones you would find in an office. Drafting chairs most often have a footrest. Executive chairs most often have more seat padding than task chairs and give ample comfort and a reclining option that most office chairs don't have. Whichever office chair you end up choosing, you can count on two things: it will be more comfortable than the chairs of the 1800s, and it will be one of the most important purchases you make.
The office chair is no longer just another piece of furniture. A lot of thought and science goes into designing office chairs. This is because a wrong selection of office chair can be harmful for your health.
The principles of ergonomics are frequently used to provide a pain free work environment. Here are some key points to look out for in a well-designed office chair -
1. Chair Height - The height of the office chairs should be easily adjustable. For this, the office chair has to be fitted with a pneumatic adjustment lever. The lever should be able to move your chair height between 16 to 21 inches from the floor.
This is important so that the user can sit according to the height of the table. The office chair should not be too high or so low, that the user is slouching or straining at the table. Elbows should be at a 90 angle to the table. The feet should be flat on the floor.
An important thing is to ensure that the knees are at a lower height than the hips. This encourages the natural 'double C' curvature of the spine that provides upright support to the body.
2. Chair width and depth - The office chairs should be wide enough to support users of any size. Usually, the office chair width should vary between 17 to 20 inches. The chair depth is the area from the front of the seat to the back.
The office chair depth should be big enough for the user to sit back against the backrest with 2 to 4 inches left between the knees and the seat of the chair.
3. Armrests - Adjustable armrests of office chairs allow the users' elbows, arms and shoulders to be rested comfortably.
4. Backrests - The backrest of the office chairs should vary between 12 to 19 inches. Again, like all parts of the office chair, the backrest should also be adjustable enough to move forward and backward as the user desires. A small cushion can be placed against the small of the back to provide a natural curve to the spine.
5. Swivel - Work in the office requires moving around the desk area - moving from the computer to the file cabinet or reaching out for the phone. The office chair should be able to rotate to enable the user to do all these things without putting the body through difficult contortions.
