While it is possible to rig another type of chair to have lumbar support, using either a rolled-up towel or a small cushion, this is not ideal. A temporary solution is likely to change its position several times over the course of the day, and the user needs to constantly adjust his seat and reposition the cushion. Built-in lumbar support is a key feature for those whose jobs require them to sit for extended periods.

Naturally, tall people have long spines and shorter people have shorter spines. Some people have short torsos and long legs, while for others it is the reverse. To ensure a user's comfort, especially in an office environment where co-workers share workstations, the buyer should consider height-adjustable computer chairs . These chairs allow the user to adjust the positioning of the backrest and the seat pan as well as the height of the armrests. Most seat designs use a dial mechanism or a lever located under the seat pan for these adjustments. Along with its curve for lumbar support, the backrest should be between 12 and 19 inches in width. It should also allow for the user to recline in the seat and lock the backrest in the reclined position. At a minimum, a chair's design should allow the user to recline at an angle of 15 degrees back from vertical. The standard width of a seat pan on an office chair is 17 to 20 inches. To determine the correct height for the seat pan, the user should seat himself at the workstation and adjust the seat up or down until his hands are at the same height as the keyboard and his forearms are parallel to the floor.

The feet should rest comfortably on the floor. When shopping for a computer chair, it is important to inquire about the chair's maximum and minimum height settings. A few chair models also allow the user to adjust the seat pan forward and backward, like the passenger seat in a car. When adjusting the seat pan in this way, the user should allow a minimum space of two inches between the lip of the seat pan and the back of the user's knees while seated. Whether to select a computer chair with armrests is a personal choice. Some computer users like being able to rest their forearms on armrests, but many find that the armrests just get in the way. OSHA advises against computer chairs with fixed armrests. A user that is either too tall or too short for the armrests may find it difficult to sit in the chair comfortably and may encounter problems with getting in and out of the chair. OSHA has identified the following hazards associated with fixed armrests: User's shoulders remain raised, causing muscle tension in the neck and the shoulders

Because the user has to lean to one side, he cannot rest both arms at the same time Too Close Together for the User User cannot get out of the chair quickly Too Far Apart for the User User's arms sit too far away from the body, causing muscle tension and fatigue Another possible issue with fixed armrests is that they may be too tall for the chair to fit under the desk, and the user has to reach further to access the keyboard. Instead of buying a computer chair with fixed armrests, the buyer should consider one that allows the user to adjust the height of the armrests. Some designs allow for users to remove the armrests and attach them again. A chair rests either on legs or on a wheel base. The problem with a legged chair is that greater force is required to push the chair toward or away from the desk while seated. Moving a legged chair from one end of the office to another or from an office to a meeting room becomes a chore. OSHA recommends a computer chair with a wide wheel base that consists of five casters.

The wide wheel base ensures that the chair does not tip over when the user leans forward or back, and the casters make it easy to move the chair around the office. Office chairs with casters are designed to travel across short pile carpets with ease, but if the work environment has a carpet with a longer pile, the office should consider investing in vinyl chair mats, which make it easier to push wheeled chairs across carpets. A seemingly innocuous action like twisting the upper body while seated to reach something on a desk can result in a serious injury. Repetitive strain injuries are among most the common class of injury in workplace settings and are the result of small repetitive movements that compound tissue damage over time. To avoid constantly having to twist the lumbar spine to reach an object, the user should find a chair that swivels 360 degrees. Instead of turning the neck or the upper body to face another direction, the user simply pushes off with his feet to turn the chair.

Nothing puts a damper on a workday quite like the clammy feeling of a sweaty back.

Those who were polled voted Herman Miller Aeron the most popular office chair. The chair sports a silver-grey mesh pulled over a curvaceous metal skeleton, leading to a sci-fi look. While strong enough to support the weight of the user, the mesh allows for ready air flow, keeping the user cool and allowing perspiration to evaporate.

In addition, padding can wear down over time until the chair's cushioning is nonexistent. eBay has an excellent selection of high-quality computer chairs.
