Item Description

Foam Dry Fast Open Cell is an open cell foam (reticulated foam) with open pores that allow water and air to pass through easily. As a result, Dry Fast foams are softer and cooler to sit and sleep on than closed cell foams. This 2" open cell foam is perfect for cockpit cushions and seating.

Dry Fast Foam is proven to be a superior cushioning material alternative with better quality, consistency, airflow, and heat dissipation. It is manufactured using a patented Variable Pressure Foaming (VPF) technology which produces the open pores that enhance airflow, drainability, and durability for more consistent comfort and a better night's sleep. Dry Fast’s open pores give it the unique ability to drain water quickly and easily, straight through the foam. This foam is also formulated with an antibacterial agent so mold and mildew will not grow.

Cut and trim foam to size using a foam cutter or even an electric kitchen knife. Pieces of foam can be glued together to form larger pieces or to reduce waste. We recommend gluing this foam with adhesive.

Sailrite recommends covering the foam with a high-performance, breathable fabric like Sunbrella for the top and sides and Phifertex mesh or Cushion underlining for the bottom to allow for moisture to escape. The result is a virtually maintenance-free foam in sun, rain and snow! Outdoor cushions will not retain water and indoor bedding feels much cooler.

Professionals also suggest laminating a thin sheet of closed cell foam to the bottom of Dry Fast for the ultimate in cushion comfort and performance. Poke holes (with a small grommet hole cutter) in the closed cell foam so the foam will drain.
