Sitting in front of a computer all day is a great way to develop chronic lower-back pain, but if your boss isn't willing to buy you a chair with lower-lumbar support, your next-best bet might be a footrest. Regardless of how often you change your seating position, footrests ensure that your feet and legs are always situated to facilitate proper back curvature, reduce foot fatigue, alleviate pressure points in your chair seat, and ensure proper circulation in your feet and legs.

Consider either version of the ruggedly built Air Tech Computer Ergonomic Flex Foot Rest, which comes in 3-inch-high Standard and double-height Tall models. Both feature a nonskid rubber surface and a clever sliding tilt/height mechanism that can be adjusted with gentle foot pressure.
