foam for deck cushions

Choosing the right foam for deck cushions is the difference between seating that stays plush all summer and cushions that turn soggy, flat, or mildewed after the first storm. Outdoor foam has to handle rain, humidity, and sun while still feeling comfortable, so it pays to know what sets it apart from standard indoor upholstery foam.

What to Look for in Outdoor Cushion Foam

Quick-Dry, Open-Cell Construction

Quick dry foam, sometimes called dry fast foam, uses a large open-cell structure that lets water drain straight through instead of soaking in. That helps cushions dry faster after rain and resist the mold and mildew that thrive in damp padding.

Density and Firmness

Higher-density foam generally holds its shape longer under frequent use. Choose firmer foam for seat cushions that take the most weight, and softer options for back cushions or chaise pads.

Thickness

Match thickness to your furniture: thinner slabs suit benches and dining chairs, while deep seats on loungers and sectionals often call for thicker foam.
