Guide
A desk you can sit at all afternoon
Five small changes most people can make in ten minutes, without buying anything.

1
Raise the screen
Top of the screen around eye level. A stack of books under a laptop works, with a separate keyboard.
2
Feet flat
Feet on the floor or a box, knees a little lower than hips.
3
Elbows by your sides
Keyboard close enough that your shoulders can relax.
4
Light from the side
A window beside you rather than behind the screen reduces squinting and leaning in.
5
Get up often
Stand, refill your water, take a call on your feet. Moving often matters more than the perfect chair.
