Ergonomic Chair Tips

What to look for in an ergonomic chair ...

"Finding the right ergonomic chair depends a lot on what kind of work you do. Choose an ergonomic chair with all the necessary features and adjustments that you can afford. It isn't always easy to get a cheap ergonomic chair or low cost ergonomic chair. You may be able to find one used, like the Aeron chair online or at eBay or some other Internet store. The features or components of ergonomic chairs and ergonomic office chairs are listed below.

Ergonomic Chair Cost

How Much Do Ergonomic Chairs Cost?

Good ergonomic chairs, ergonomic office chairs and ergonomic computer chairs usually start at about $400 new. Ergonomic chairs can cost as much as $1000. And some of the Aeron ergonomic chairs cost from $500 to more than $1000. You can think of it as an investment in your health.
Ergonomic Chair Casters and Baset

Use a chair with casters and a 5-point base to ease movement and minimize possible tipping. Generally, nylon carpet casters are standard, but soft wheel casters are available for hard surfaces such as linoleum. Rubber locking casters are useful on stools to prevent tipping.

Ergonomic Chair Seat Pan

The seat pan is the component of the chair that supports the majority of the user’s weight. It is important to purchase a chair which uses dense, small-cell foam padding or spring coils to retain its support and cushioning (this usually involves purchasing a chair over $250.00). The front part of the seat should slope down slightly (waterfall design) and allow a fist size gap between the back of the knees and the front edge of the seat pan to reduce pressure at the back of the thighs. Tilt adjustments are preferred to allow a forward working posture to be attained or a reclined posture. A seat pan with a sliding mechanism is also a beneficial feature. This allows small and tall users to adjust the distance from the back rest.

Ergonomic Chair Backrest

Adequate lumbar support is the most crucial element of a backrest. The backrest should either be small enough to fit into the small of the back, clearing the pelvis and back of the rib cage, or curved to provide adequate support. Many chairs come with a built-in lumbar adjustment which can be adjusted by turning a knob on the side of the chair. Inadequate lumbar support places excess pressure on the spine. Remember, a lumbar support cushion properly placed behind the small of the back can help to accentuate lumbar support. The backrest should also have angle, in-out, and height adjustments to achieve proper spinal alignment. The angle adjustment allows the user to adjust the angle of the back rest relative to the seat pan, as apposed to the tilt mechanism, which moves the seat pan with the backrest. When you change the tilt, the angle between the seat pan and the backrest stays the same."    (Continued via Ergonomic Chair Tips)    [Ergonomics Resources]

I just broke down and finally bought a Herman Miller Aeron and now I wish I'd done it sooner. I work from home and it makes a huge difference when the chair you sit in for 8+ hours a day is ergonomic. Aeron's are known for being super expensive but you can actually get used one's in great condition for a decent price. I used Aeron Deals to find mine and it worked out great!
