The Apex series caster chair has the same modern and ergonomic design as the stacking chair with the addition of 2” swivel casters for easier mobility. The patented seat shape is contoured to provide maximum comfort throughout the day. The seat has a contoured back that is shaped and angled for sitting upright or in a slightly reclined position. The front edge of the seat is swept downward for productive, over the desk task work. The stylish shape allows freedom of movement, functional support, and a great value.
