How to Reupholster a Pontoon Corner Bench Base

Item # X-HT-300489

In this installment of our "Pontoon Upholstery Series," we’re upholstering the base section of our pontoon’s corner seat. This is just one of three videos we created showing you how to reupholster the corner seat on a pontoon. If your backrest (#300487XHT) or seat (#300488XHT) also needs new upholstery, be sure to check out those blogs as well so your entire corner seat can get a fresh new look.

Pontoon corner bench base DIY.

The old vinyl on our pontoon was in pretty bad shape. For our new upholstery, we chose EverSoft™ indoor/outdoor vinyl upholstery fabric only available at Sailrite®. The vinyl is UV, abrasion and stain resistant as well as waterproof — making it a fantastic choice for marine upholstery. There's a lot of shaping and angles on a corner seat, and EverSoft's four-way stretch properties make the vinyl easy to stretch and staple into place.

In this video, we’ll show you how to remove the old vinyl and use it to pattern your new vinyl panels. After sewing the vinyl panels together and stapling the fabric to the pontoon base, we’ll show you a trick for removing wrinkles from vinyl with steam. The final step is hiding the staples with hidem gimp.
