An ergonomic footrest is simply what it sounds like! A place to rest your feet when in a seated position. These devices are designed to take the pressure off your legs, feet, and back. They come in many forms and are meant to increase your overall comfort when sitting in a chair. Sitting for too long can cause lower back pain, leg cramps, swollen ankles and fatigue. WebMD also reminds us that it can also cause deep vein thrombosis – a clot that forms in the legs. A footrest helps to encourage ‘active sitting’ by supporting your feet while you sit, and reducing pressure on your legs.   It is also a good solution for shorter folks whose feet are unable to touch the ground while sitting. Office chairs are adjustable, but they have their limits so the footrest allows for proper weight distribution.
