Read the guide, then continue.
Feet and back
Both feet flat on the floor. Sit back in the chair so your lower back is supported. Do not lean toward the screen.
Arms and wrists
Elbows near a right angle, forearms roughly level with the desk. Wrists float; they do not rest hard on the edge of the table.
Screen
Top of the screen at eye level, about an arm's length away, so you can read without lowering your head.
