The equipment in your office and its arrangement are vital to your well-being. Your height adjustable computer desks should be roomy enough for your computer, monitor and mouse and any other items you need to have on hand. Your legs should be able to stretch out and relax with plenty of room. Your chair should be comfortable with a healthy design. This could include a padded seat, adjustable height, back support and wheels that are secure and stable. If your feet do not reach the floor and your office chair does not adjust, you should use a foot rest to give your feet and legs support throughout the day.
