Our Premium Pontoon Boat Seats are ergonomically designed with plush molded soft and dense marine foam for long-lasting comfort. They offer 1.5" more cushioning than our classic line. We use double-top stitching on all stress points, so you never need to worry about torn seams. Our pontoon boat seats look new longer! We have designed our Classic line of seats to look like the OEM seats you see on new pontoon boats. Now you can really make that old pontoon look like it came directly off the pontoon factory floor. Our pontoon seats will last! The quality of your vinyl and foam won't matter if your seams tear or rot. That's why we only use the best UV treated polyester thread. 32 oz marine grade seat vinyl is coated and treated to exceed industry standards for UV resistance. Our pontoon boat seat cushions are built with a mix of soft and dense foam for a plush boating experience. Seat bases with molded drain channels increase the life of your pontoon flooring by allowing water to escape your deck instead of being trapped and left to soak into your carpet and decking. No wood! All of our pontoon furniture frames are plastic. We use injection-molded plastic seat cushion frames and rotationally molded plastic seat bases. High-grade stainless steel hardware and staples are used on our pontoon seats, along with t-nuts, which are inserted into the plastic bases to secure each pontoon seat cushion.
