Begin your day with a healthy outlook! Transform sitting at your desk into an active experience with this ball chair that promotes healthy posture. Original concept by Pilates instructor Maria Mankin, developed in collaboration with Balanced Body®. Available exclusively from Balanced Body, the Begin Chair® is a beautiful and functional addition to your home or office. It is also the only ball chair available with comfortable lumbar support that adjusts to your spine’s natural curves. The small ball in back adjusts up and down, or in and out, to fit every spine. It will provide friendly yet firm feedback if your posture deteriorates. The large fitness ball (55cm) is our highest quality, burst-resistant ball. It provides the right amount of instability to activate core muscles. If needed, adjust your seated height by slightly deflating the ball. Back away from your desk during the day, and the chair is also great for a seated exercise break. Balls are Storm gray and must be inflated (pump included).
