Sitting still for long periods of time may not seem like a big deal, but it can result in back pain, weight gain, and even bad posture. Vivora offers a solution in the form of a ball—an active sitting ball to be exact. The Luno is a beautifully designed active sitting solution that engages your core so you can stay active while sitting down. Sitting on a Luno gives you the freedom to wiggle, bounce, shift all day long to help strengthen your abdominal muscle and improve your posture, avoiding all the negative side effects that come with sitting down for hours.
