What goes into the award-winning line of Rio® stackable plastic chairs? Patented flexing technology, for one. Add a fresh, modern color palette and an extra-slim, stackable frame and you’ve got a multipurpose seating solution that allows for more movement, day-long comfort and flexibility than any other chair in its class. Our complete family of Rio® models feature our patented Active Rebound Control (ARC) Technology® - a performance-minded flexor insert that supports a wide range of motion (20 full degrees to be exact) and responds precisely to the amount of weight pressed against it. The Rio is an easy choice for multi-use spaces that require quick set-ups and breakdowns.
