I want to scream.

Arms at 90 degree angles - can't do it.
Legs at 90 degree angles, knees in line with hips - nope.
Knees 2-4 inches away from edge of chair - nuh uh
Top of monitor even with line of sight - yeah, right.

These ergonomic designers have obviously never needed to help someone who's short. Everything is too high or too deep.

And this uneven floor isn't helping any. I keep ending up to the left of the desk because the chair keeps rolling in that direction.
