New on the chair front is the Zenergy Swivel Ball Chair from Safco. Unlike traditional ball chairs that set a standard exercise ball on a rolling base, Zenergy uses a smaller, anti-burst ball on a molded rubber base, giving you freedom of movement without the slippage. You can lean and spin to your heart’s content.Zenergy is available with mesh covering (black, blue, orange, or green) or in black vinyl, and every chair comes with its own pump. Visit Source today to take Zenergy for a spin, and discover a new way to sit. Source Office Furnishings — Making Your Office Work Better!
