You get to work nice and relaxed, but by the end of the day, you're fidgety and achy. Sound like you? Prolonged sitting can have several negative effects on the body. Leg activity is vitally important for maintaining good circulation and comfort, so a good quality footrest could be your solution. They elevate and support your legs, thus increasing blood flow which can relieve pressure on your lower back. Choose from models that adjust, rock, have stimulating bumps, and even heat up.
