You’ve heard that sitting on normal chairs, even those advertised as “ergonomic,” can be harmful to health, while sitting on an inflated “therapy ball” is best for us. It’s true. Sitting on a ball requires active sitting, constantly using our muscles to adjust to the ball’s subtle movements, thus promoting muscle maintenance and development, and counteracting the negative effects of sitting too much. Spinalis chairs do just this: They replicate sitting on a therapy ball, but add back support and a variety of elegant, practical shapes and designs, to suit any work or home environment.
