Designed for long days on the water, this captain bucket seat pairs a 23.6-inch high back with wraparound support that relieves pressure on the head, neck, spine, and legs. Waterproof Pvc leather over high-elastic sponge padding resists Uv rays, wear, and moisture, while precise stitching keeps the cushion intact season after season. The flip-up bolster folds away to save deck space and lifts into place for a raised, comfortable seating position with reduced leg pressure. A high-toughness Pp frame delivers rust-proof, deform-resistant support, and two mounting patterns of 5 x 5 inches or 5 x 12 inches make installation quick on most fishing boats, speedboats, and canoes. Mounting screws and washers are included pedestal and swivel are sold separately.
