reticulated foam vs open cell foam

Choosing between reticulated foam vs open cell foam comes down to one question: will your cushion get wet? Both foams let air move through them, but they handle moisture very differently. Picking the right one keeps your seating comfortable, fresh, and long-lasting.

How the Two Foams Differ

Reticulated Foam

Often sold as dry fast foam or quick dry foam, reticulated foam starts as open cell foam. The thin membranes between its cells are then removed, leaving an airy, skeletal structure. Water drains straight through instead of soaking in, which helps the cushion dry quickly and discourages mildew. That makes it a top choice for outdoor cushion foam, boat seats, and poolside loungers.

Standard Open Cell Foam

Traditional polyurethane upholstery foam has open cells that breathe well but still trap moisture. It feels soft and supportive, comes in many firmness levels, and shapes easily, making it ideal for indoor sofas, dining chairs, headboards, and window seats.

What to Look For

• Exposure: outdoors or damp areas call for reticulated foam.
• Feel: standard open cell foam usually offers a smoother, plusher sit.
• Cover fabric: pair dry fast foam with breathable outdoor fabric so water can escape.
