Update or replace the seats on your boat with a Wise Mariner Mid Back Boat Seat. In less than a day, and for less than you think, you'll be in command of a more comfortable fishing boat. The frame is built from injection molded high-impact plastic to provide a sturdy base, outfitted with compression foam padding and covered in heavy 28-oz. marine-grade vinyl that is UV treated and mildew resistant. The mid back is joined to the seat frame by a pair of aluminum no-pinch hinges. All together they form a Boat Seat designed to last for years and also give you more comfortable protection against pounding waves on your favorite body of water.
