"The You® chair encourages you to sit actively – all day and regardless of the task at hand. With its U-shaped back suspension, the You chair introduces a revolutionary way of sitting that ‘lifts’ you into the proper position."

From Allseating:
The single most important part of a healthy work environment is your chair. Unfortunately, most people don’t take the time to learn how to adjust their chair so it fits them perfectly. The You chair makes sitting fit both easy and intuitive. All controls are within easy reach so you can quickly make the adjustments you need to be at your best. Similar to sitting on a yoga ball, the You chair engages your core muscles, elongates the back, opens your chest and keeps your shoulders down and relaxed. That means you sit up tall and light on your sit bones.
