ergonomics

After working in-place with many analog & digital technologies over the years, i have always experienced fatigue and posture-related pains after long sessions in front of screens(primarily crt, more recently lcd).
I've tried many seating technologies, from 'wheeled kneelers' to high priced 'ergonomically correct' chairs and everything in-between (including bar stools & milk crates!).

It seemed that no matter how much research time I've spent on finding the ideal seating technology, i've ended up tired and achey after several long days, and need to spend much money for massage and many hours on re-alignment.

Recently i've found a solution that has worked wonders for me: the yoga ball! it's a simple, elegant soulution which promotes active posture control and actually helps to tone key muscle groups, something that no backed chair can claim.

The increase in total energy flow through active sitting is noticable at the end of a long day. The yoga ball also allows you to lean back and stretch otherwise clenched joints. I've basically eliminated lower back pain, strengthening muscles there as well as stomach, hips, thighs & calves.

The yoga ball is infinilely customizable by variations in air pressure and posture positioning by the individual sitter.

Another great advantage is cost. i can tell you the ball costs one just one 12th-15th of the cost of the best designer chair i've used. At about $40 dollars, it's the best ergonomic investment i've ever made!
