Ergonomically designed to perfectly contour your body for all-day comfort. The heavy-duty flip-up bolster offers dual functionality: raise it for enhanced seating height during activities like fishing, or lower it for sturdy back support while standing—improving visibility and safety in dynamic marine environments. Constructed with 28 oz marine-grade vinyl and high-density compression foam padding, this seat resists sun, heat, rain and saltwater corrosion. Rigorously tested to endure extreme marine conditions, it maintains structural integrity through years of sun, seawater, and heavy use. Dimensions: 23.5"H x 20.5"W x 26"D. The extra-high backrest is engineered to cradle your shoulders and lower back, reducing fatigue during extended voyages—ideal for captains and anglers alike. Includes a heavy-duty waterproof seat cover that shields against dust, moisture, and scratches. Easily wipe clean after adventures or store compactly when not in use—extending your seat’s lifespan through seasons of harsh weather. Quick-install design fits standard 5”x5” and 5”x12” bolt patterns—hardware included. (For swivel functionality, pair with our compatible 360° base, sold separately.)
