Boat cushions live in the harshest environment a cushion can: spray, humidity, sun and salt. Everything we recommend for boats starts from one rule — water has to be able to leave.
V-berths, quarter berths and odd shapes
Boat berths are never rectangles. The V-berth up front is a trapezoid (wider at the foot, tapering toward the bow) — the configurator prices that shape directly. Quarter berths and settees get measured the same way: widest points, ±¼″, rounded corners where hull panels taper. Measure the bunk platform, not the old cushion.
Foam: Dryfast for everything the spray reaches
Dryfast reticulated foam is the marine standard for cockpit cushions, helm seats and deck loungers: open cells let water drain straight through, and airflow dries the cushion in hours. For inside cabins and sleeping berths, use HR45 high-resilience — drier down below, and it holds up to the constant motion. Thickness: 3–4″ for seating, 4–6″ for sleeping berths.
Covers that survive a season on the water
360° waterproof outdoor fabric is the workhorse; for premium marine upholstery, supply your own fabric (COM) — we charge labor only, by covered area. Light colors stay noticeably cooler on deck; whichever you choose, our outdoor cushions care notes apply equally on the water.
Cockpit, flybridge and deck seating
Measure each seat individually — production boats vary seat to seat. Rectangle and trapezoid cover most layouts; semicircles and wedges fill bow riders and transom benches. Everything is priced instantly, so you can work through the whole boat one seat at a time.
