Chairs should have an adjustable backrest, allow the seat height to be adjusted, have a 5-caster base and have adjustable arm rests.

Keyboards should be seperate from the screen, should be tiltable, should have a matt surface to reduce glare and should include enough space to rest your wrists. 

There should be no point sources of light (to reduce reflections on screen), adjustable blinds reduce the amount of sunshine entering through windows and matt grey keyboard, mouse, screen etc to reduce glare.

Desks should be at the correct height, have a non-reflective surface and have plenty of room to work on.
