Stable and Durable: The PP frame of our folding fishing boat seat, assembled with corrosion-resistant screws, provides firm support. It ensures the seat won’t deform, break, or bend, even when leaning back fully. Foldable Design: The backrest of our fishing boat seat can be smoothly unfolded or folded, making it easy to store without taking up too much space. No Fatigue After Long Sitting: The backrest and seat cushion are made of high-elastic thick foam, providing softness and resistance to flattening. The flip up boat seat ensures comfort for long hours on the water, relieving pressure on your back, spine, and hips. 5.3" x 5.3" Bolt Hole Installation: The folding boat seat features a 5.3" bolt hole spacing. We provide corrosion-resistant screws and washers, making it easy to securely attach the seat to most boat swivels or bases. Please note, the boat base and swivel are not included. Durable PU Seat: The boat seat surface is made of durable PU polyester fabric, providing water resistance, wear resistance, and UV protection. With precise stitching to avoid tears, it’s built to last in both marine and outdoor conditions.
