Marine Exterior Foam

Revamp the cushions in your boat with high-quality marine exterior foam from Sailrite^®. We’re experts when it comes to helping customers create one-of-a-kind boat upholstery and we know that choosing the right marine-grade foam is an important part of the process. The Sailrite team has hand-selected an assortment of high-performance boat cushion foam for sailboats, power boats, pontoon boats and more. Pair any one of these long-lasting options with some of our exterior cushion fabric and lifetime thread for an enduring boat cushion that will handle the demands of the high seas with ease.

We have a variety of types of marine foam in our selection. Polyurethane marine foam is a good choice for upholstering seats on a powerboat or pontoon boat, as it features antimicrobial properties and soaks up water. For that reason, we don’t recommend using it on any cushions that will be covered in a woven fabric. If you plan to upholster your boat cushions with a vinyl fabric, polyurethane foam is a solid choice. Medium Density Polyurethane Antimicrobial Foam is the standard foam used in outdoor cushions and boat seats and can be wrapped in silk foam for moisture protection.

For an even stronger option for applications such as your sailboat’s cockpit cushions, you will want to use a closed cell or Dry Fast foam. This is three times more firm than polyurethane foam and doesn’t absorb moisture, so it can be upholstered with some water-resistant woven fabrics. This type of foam is highly weather-resistant and abrasion-resistant and it also offers no combustion support, so it passes rigid federal motor vehicle safety standards. Regardless of which style you choose, you can tailor your cushions to your desired firmness and thickness with Sailrite’s selection.
