Best foam for outdoor cushions
The best foam for outdoor cushions is open-cell dry-fast foam. Because its cells are open and connected, rain drains straight through and the cushion dries in hours instead of staying soggy, so it resists mold and mildew. Regular indoor foam soaks up water and rots outdoors — dry-fast foam is what keeps patio, boat and poolside cushions usable season after season.

Outdoor cushion foam — answered
What is the best foam for outdoor cushions?
Open-cell dry-fast foam is best for outdoor cushions. It lets rain drain straight through and dries in hours, resisting mold and mildew, while regular foam soaks up water and rots outdoors.
Can I use regular high-density foam outside?
Only under cover where it never gets wet, and even then a waterproof cover is essential. For any seating exposed to rain or dew, use dry-fast foam so water can drain out.
What thickness should outdoor cushions be?
Most outdoor seat cushions are 3–4 inches thick for comfortable deep seating; backs are usually 3 inches. You choose the exact thickness when you customize.
Does the fabric matter as much as the foam?
Yes. Dry-fast foam handles drainage, but you also need a fade- and water-resistant, UV-stable outdoor fabric so sun and rain don't ruin the cover. The two work together.
How long does it take and do you ship to me?
Each cushion is made to order and shipped worldwide with free, tracked delivery — you'll see the current lead time at checkout. If the fit isn't right, our 14-day perfect-fit guarantee means we remake it.
