An ergonomic footrest makes life a lot more comfortable while sitting at your desk all day. However, there are health benefits to be gained as well. Blood Circulation   Sitting for too long can lead to poor blood circulation, especially in your legs and feet. An ergonomic footrest allows you to elevate your feet and legs or encourage movement to keep the blood flowing. Back Pain Sitting in an office chair for long hours can put strain on your spine and cause back pain. A footrest allows you to sit properly in your chair and take the pressure off your back. Posture An ergonomic footrest can be used as a tool to improve sitting posture. It takes the pressure off the back of your legs and allows you to rest both feet on the device. An under desk footrest can be adjusted to ensure that you sit with your back straight and your hips positioned a little bit higher than your knees. Comfort It can also be much more comfortable to have a footrest especially if your feet tend to dangle off the edge of your chair.
