🌊 Waterproof Foam for Deck Seating
Upgrade your outdoor or marine space with premium waterproof foam for deck seating, cut precisely to your measurements. Whether you’re restoring garden decking, outfitting a boat, or building custom patio seating, our foam offers durable, all-weather comfort that holds up in demanding environments.
✅ Why Choose Our Deck Seating Foam?
This foam isn’t just comfortable — it’s made for outdoor and marine performance:
🌀 Quick-Dry GraviDry™ Foam – Our most popular waterproof foam. Its fully open-cell structure allows rain and moisture to drain through rapidly, preventing waterlogging.
☀️ UV-Resistant – Designed to resist sun damage, so it won’t degrade, harden, or crack over time.
💪 Firm Support – Choose from firm or medium-grade foams, depending on your seating style and usage needs.
💧 Optional Waterproof Liner – Add extra protection and make your foam easier to insert and maintain.
✂️ Custom Cut – Enter your dimensions for a perfect fit. No trimming required.
📌 Ideal For:
-
Deck bench cushions
-
Garden deck built-in seating
-
Boat deck lounge pads
-
Waterproof poolside seating
-
Balcony and terrace seating
✂️ Precision Cut to Size
Use our Foam Cut to Size Tool to enter your dimensions. If your seating requires curves or angles, upload a template and we’ll cut it exactly to spec.
🧵 Pair with a Breathable Liner or Outdoor Cover
A breathable waterproof liner is highly recommended for deck seating, especially where exposure to heavy rain or spray is expected. Pairing with UV-stable fabric covers adds even more protection and enhances the look.
💡 Tip: Air out the foam periodically for best long-term freshness.
