You may already be familiar with the benefits of sitting on a ball as an alternative to a chair; the ErgoErgo is an even better option. The already cool un-chair is now available in a 15″ children’s size. With a kids Ergo there’s no concern of a ball rolling around, picking up dirt, or taking up space. Sitting this way allows the body to rock gently in any direction to build strength and flexibility, and has been proven to help children focus better. Homework problems, be gone! As an added bonus, it looks pretty neat too.
