foam cut to size for boat

Ordering foam cut to size for boat cushions is the easiest way to get seats, berths, and backrests that fit your hull perfectly, with no trimming on a wobbly dock. Whether you're refreshing a pontoon lounger or rebuilding a cabin V-berth, the right marine foam keeps you comfortable while standing up to spray, sun, and humidity.

Choosing the Right Marine Foam

Boats are tough on cushions, so the type of foam matters as much as the fit.

Closed Cell Foam

Closed cell foam doesn't absorb water, which makes it a smart pick for open-deck seating, casting platforms, and anywhere cushions may get soaked. It tends to feel firmer and holds its shape well.

Dry Fast Foam

Dry fast (reticulated) foam has an open structure that lets water drain straight through and air circulate, helping cushions dry quickly and resist mildew. It pairs well with breathable outdoor fabrics or mesh-backed covers.

What to Measure Before You Order

• Length and width of each seat base or backrest
• Thickness that suits how the cushion will be used
• Angles or curves along the hull or console

Finish your project with marine vinyl or outdoor upholstery fabric for a durable, water-ready cover. Browse the custom-cut boat foam options below to find the right fit for your vessel.
