"Swop" out your old office chair from time to time for a little fun with the buoyant Swopper Chair. Designed to compliment traditional ergonomic chairs, the Swopper's active seating design allows for you to move vertically and horizontally to promote dynamic movement (or "swopping") using your core muscles. This new approach to ergonomic seating engages your core, strengthening and conditioning your body through subtle movement while also improving circulation, alertness, and productivity. The Swopper comes in a plethora of vibrant colors with hundreds of fabric, suede, and leather options, with multi-color seats and user-chosen fabric options also available. For an extra bounce of color, the Swopper Special edition offers a matching dyed spring to give your chair a striking modern appearance.
