    FAQs

    Do I need to send a template for a boat mattress?
    Yes. Boat berths are rarely square, so a template or DXF file ensures the most accurate fit.

    What is GraviDry® reticulated foam?
    GraviDry® is a premium quick-dry reticulated foam designed for marine and outdoor use. Its open-cell structure allows water to flow through freely, meaning cushions dry quickly and resist mould and mildew.

    Can you cut complex or angled shapes?
    Yes. Our CNC profiling machines cut irregular shapes, curves, and complex angles with ease.

    What foam grades are best for boat mattresses?
    We recommend medium or firm foam for sleeping areas, with the option of adding a memory foam topper. For outdoor seating, GraviDry® reticulated foam is best.

    Is the foam suitable for damp environments?
    Yes. All our foams are durable, but for wet or exposed seating, we recommend GraviDry® reticulated foam for long-lasting performance.

    Do you supply trade orders?
    Yes. We supply boat builders, upholsterers, and marine specialists, with both retail and trade supply available.
