I found that using a Kinesis freestyle keyboard improved my sitting posture a lot. The keyboard is split in half and connected by a wire and I have them set up about shoulder width apart. With a normal keyboard I pull my shoulders inward which causes me to slouch. Now I can lean back while typing.

I have a Kinesis Advantage: http://jseliger.com/2009/07/20/kinesis-advantage/ , which has also helped me quite a bit.

Consider one of these. They make a huge difference for me.

(My cardboard/duct tape clone cost $4, about 50x less than the official version.)

I've been meaning to build one, especially since I recently bought the 20" version (I have the 8" version at work). No way I can justify spending twice as my keyboard on a keyboard holder though.

I am confused as to what you are suggesting to get or how it works based on the picture.

I have the keyboard in the picture (the Freestyle) but I do not have the "tenting" accessory that is holding the keyboard in a vertical position. He was suggesting I get/build that.

I have the VIP accessory which lifts each half 15 degrees, but that's still pretty far from 90.

When you make a 90 degree angle with your elbows, it is natural for your palms to face each other. When you point your palms down for long periods, it causes torsion in your forearms which can cause pain.

I've reduced that pain by using a vertical layout keyboard.
