This rotationally molded chair is foam filled and has an aluminum inner frame for added strength and durability. Ergonomically designed for maximum comfort, the seat is contoured in the front to eliminate any discomfort on long trips. The contoured front also allows the chair to be used as a leaning post when it is necessary to stand at the helm. A positive locking fore and aft slide assembly allows for quick and sure adjustments and the stylish removable cushions eliminate water absorption.
