Stance | A stacking chair for BH, Caliber is constructed of injection-molded polypropylene in one continuous piece. Its seamless construction, structural span and reinforced leg design produces its strength – it has been tested to sustain a 1500lb. static load. A 30” low-back design resists leaning and rocking, and the rear legs have added structural ribs to prevent buckling. It’s easy to clean, weighs only 8lbs. and stacks 10-high without leaning forward. A pilot-hole indicator in the feet provides a bolt-to-floor option. And Caliber meets the CAL TB133 flammability standard.
