Avoid Agony of the Feet: Use a Foot Stool for Ergonomic Seating
Some people find that their computer desk is too high, but when they raise their chairs to achieve a neutral typing position, their feet dangle above the floor. The act of pressing your feet against the floor or a stool is essential to help counterbalance the pressure that extended periods of sitting puts on your low back. If you can't replace the desk and a keyboard tray is not feasible to adapt your workstation so your feet reach the floor, a foot stool can help. You can buy adjustable stools where ergonomic office furniture is sold.
