The Acton® Stacker is the perfect solution for any meeting of the minds. This freestanding, sled-base chair is well-suited for use in classrooms, auditoriums, convention centers, libraries and training facilities. Optional connectors allow for ganging together to create row seating, and the co-polymer or case hardened steel frame glides easily across the floor for easy positioning and movement. When not in use, the non-upholstered chairs stack 26 high and upholstered chairs stack 18 high.
