Your pontoon can experience a lot of wear and tear from the weather, people, time and more. If your pontoon corner bench seat is in need of an update, you're in luck. In today's blog, we're going to show you how easy it is to upholster your corner seat in beautiful new vinyl fabric. Join us for this tutorial in our Pontoon Upholstery Series.

Pontoon corner bench seat DIY.

We're using EverSoft™ indoor/outdoor upholstery vinyl for our pontoon upholstery. EverSoft is a beautiful four-way stretch vinyl with a soft hand and excellent durability. It's waterproof, stain resistant, UV resistant and easy to clean. It's a great choice for boat upholstery and cushions. Instead of using a patterning material, we'll show you how to pattern your vinyl from the existing, old vinyl.

There is a lot of shaping and contouring with this corner seat. We'll show you how to number and add matchup marks to every seat panel so that assembly of the new vinyl will be easy and mistake-free. You'll also learn how to add new piping, create a fabric pull, join the panels together and more. The final step is to remove any wrinkles from the seat. We'll show you a trick for using a clothing steamer to gently remove wrinkles in the vinyl.
