Better Vinyl - DeckMate uses 30oz marine grade vinyl with larger amounts of UV & mildew protectant chemicals so our seats will last. We spend the extra money to use higher quality materials. * Better Stitching - DeckMate uses stronger and more durable thread as well as double stitched seams so your stitching won"t rip or rot. * More Foam - DeckMate seat cushions are pillowed and use a mix of soft & dense foam to provide comfort & support where it matters. * DeckMate Pontoon Furniture is designed to last with fully enclosed, molded plastic bases and injection molded plastic framework. Lifetime warranty on all 100% plastic framework - 3 year warranty on vinyl. * We will return or exchange, at our expense, any DeckMate Furniture that does not meet your quality expectations.
