How to Reupholster the Backrest of a Pontoon Bench Seat

Item # X-HT-300450

As part of our Pontoon Upholstery Series, we'll show you how to reupholster a pontoon boat's bench seat. This tutorial will highlight the reupholstering of the backrest. Follow along as we walk you through removing the old vinyl, cutting and shaping foam, patterning new vinyl fabric, sewing and stapling the vinyl to our frame. To ensure our project looks great and lasts a long time, we’ll be using only the highest quality tools and supplies from Sailrite®! Let’s get started.

For our upholstery project, we’ve chosen to use EverSoft™ Indoor/Outdoor vinyl. This waterproof vinyl is incredibly soft and supple, with a grain that closely resembles real leather. This vinyl is easy to clean, as well as resistant to mold, mildew, abrasion and fading. The Nanocide™ Silver Ion Antimicrobial Agent formulation enables EverSoft to withstand harsh conditions, preventing the growth of mold and mildew, while the proprietary Blockade™ special finish ensures years of abrasion and UV resistance. EverSoft promises a strong resistance to bacterial pinking, which can lead to unsightly pink stains on marine seating. Wherever you need a quality vinyl, look no further than EverSoft Indoor/Outdoor Vinyl Fabric, only available through Sailrite.

To cut our medium density polyurethane antimicrobial foam for this project, we’re going to compare using the Sailrite® Blade Foam Saw and a regular electric kitchen knife. While an electric kitchen knife will technically cut through the foam, it takes longer and leaves uneven cut marks because it cannot adequately secure the foam while it cuts. However, our dual-blade Sailrite Blade Foam saw has one stationary blade to secure the foam (no bouncing) and another blade to glide through the foam. This will make your next upholstery project a breeze!
