What is the proper way to sit at a computer desk? Adjust the chair height so your feet are flat on the floor and your knees are in line (or slightly lower) with your hips. Sit up straight and keep your hips far back in the chair. The back of the chair should be somewhat reclined at a 100- to 110-degree angle. Ensure the keyboard is close and directly in front of you.
