Active Pony was designed to encourage movement by gently rocking 7 degrees in all directions. This added movement activates a wider variety of core muscles, which helps build strength and minimizes fatigue. Active Pony features locking casters that stay in place while you are engaging the stool. It also offers the same ergonomic design, support, and comfort as our other Freedom stools. While traditional stools are often uncomfortable, static, and stiff, Freedom Ergonomic Stools incorporate the same ergonomic design considerations as every other Humanscale product. The result is a fun, versatile, and supportive stool that encourages movement while remaining comfortable and promoting workspace wellbeing. WHAT IS A NET POSITIVE PRODUCT?
