How can you work for 8 hours a day (assuming full-time work by a pc) elevating your wrists everytime you type? That sounds very exhausting.
given the right workspace setup it's like driving a car -- yes your arms are elevated but you have some extra support so you're not just holding your arms out in front of you.
it's not too hard and it actually gets more comfortable as you get used to it. it helps to have arms on your chair that are worth a damn.
Exactly. When looking for a work chair, the arm rests are just as important as the seat. They should at least adjust in height. Adjustment in and out is a plus. But you need to raise the arm rests so that your elbows rest on them in a neutral position. This eliminates having to hold your arms up with your shoulders.
The below link is to Bodybilt chairs. Probably overpriced for what you're looking for, but they're a great example of what arm rests 'should' do...
http://www.ergogenesis.com/products/ergonomic-seating/task-chairs/high-back-taskI had a custom Bodybilt chair built for me about 20 years ago. Cost me $1,800 in leather. I still use it to this day, and I consider it one of the best office equipment purchases I have ever made. All these years and no back, shoulder or neck problems. A good chair is a good investment if you work at a desk all day. 20 years ago, there weren't that many ergonomic chair options. Today you can pick something up that will accomplish the same thing for a lot less.
We are all into keyboards on this forum, and we understand the importance of quality input devices. We all have buddies who have gaming computers and buy $500 graphics cards, yet can't see the value in spending over $30 for a keyboard. Keyboards are one thing most people don't even consider, yet are one of the most important pieces of your computing environment.
My point is...a good chair is just as important as a good keyboard. Your body will thank you for it years down the road.
