For those interested in environmental concerns, the use of recycled materials might also be a factor.
"Consider chairs that are made of recycled materials and that can be recycled at the end of their ' useful lives," Scrivner says. She points to Herman Miller's Aeron chair as an example of a high-quality chair with a sustainable design. It's made largely of recycled materials, and its major components can be easily replaced and then recycled.
The perfect fit
A perfect fit for one person can be lousy for someone else. For that reason, a trial run may be in order. "The best way to tell if a chair is a perfect fit is to learn how to adjust it and then try it out for two to three days," Scrivner says. "Often people sit in a chair on display for a few minutes and then decide whether or not they want to buy it. This is a huge mistake, as the postures and time spent in the chair in the office environment will vary significantly from the postures used when briefly trying out a chair while it is on display in the store."
A good test is to adjust the chair so you can sit with your feet flat on the floor and your knees at right angles. In this position, there should be approximately four fingers' width of distance between the edge of the seat and the back of your knees. At the same time, the arm adjustments should allow you to type comfortably on a keyboard with your arms supported by the armpads. Lumbar support should also align properly with your spine curvature.
Be sure and re - create your most common working positions, such as working on a computer for an extended time. Also while trying out a chair, adjust the height, determine how the back contours fit, and adjust the arms if they're adjustable.
Buying time
Prices for office chairs vary greatly. You can pay as little as $20 for a simple task chair or well over $1,000 for an executive model. Chair prices reflect technology, features, upholstery, and materials as well as warranties.
For most selections, expected longevity is a key factor. If you don't mind replacing a chair or some of its components every fewyears, an inexpensive model can be satisfactory. But for long-term use, a more costly choice may be best. Scrivner recommends that if you want a chair to last 13 years or longer, plan on spending $500 to $875.
The same kind of logic can be applied in deciding where to buy. Chairs that are readily available at superstores, especially the more inexpensive models, will appeal to some buyers. But many office furniture experts advise buying from dealers. With the latter, you're more likely to find expertise in selecting the right chair, a wider selection of high-quality products, and a chance to try out a chair before you buy it.

10 FEATURES TO CONSIDER
Shannon A. Powell, president of Active Ergonomics in Raleigh, N.C., recommends selecting chairs with the following features:
1 a height range of 16 to 21 inches
2 back-angle adjustment (allows some users to sit with a more open hip angle than others)
3 seat-depth adjustment (especially helpful for taller users)
4 back-height adjustment (allows adaptation to different lumbar curves)
5 an option for additional lumbar support
6 the ability to lock the chair in any tilt depending on the tasks
7 adjustability of arms in both height and width (keeps arms from getting in the way and inhibiting your ability to get closer to the work environment)
8 the ability to remove arms completely if needed
9 if applicable, carpet casters for carpet or hard-floor casters
10 a good warranty.
