This is the office chair crafted in Langenneufnach, Germany to provide ergonomic task and office seating using a special mesh support system that cradles the body and spine, relying on the sitter's own body weight to automatically control chair alignment without the need for constant adjustments to dials and levers. Mesh tension can be easily tuned to a preferred level of firmness, while a fully adjustable lumbar module allows customization of lower back support. The combination of lumbar support and tension-controlled mesh helps the spine achieve the proper upright curve for correct posture without forcing the back into an uncomfortable position, so the chair molds to the sitter instead of forcing the sitter to conform to the chair. The mesh provides a breathable back that ensures airflow during long periods of sitting to increase comfort and prevent overheating. The chair back can be tilted from 85° to 138° for upright or reclined seating, while the armrests raise and lower at the touch of a button and lock in place at the desired height. The headrest is adjustable to ensure proper positioning at the base of the skull that helps train the body to sit in proper posture and spinal alignment. The seat is comfortably padded with 2" of high-density fire-retardant foam that supports 250 lbs. and the black die-cast aluminum base rolls smoothly on five dual-wheel oversized locking casters. Imported. 55" H x 26" W x 26" L. (45 lbs.)
