Reticulated Foam Cut to Size – Fast Draining Foam for Wet Cushions (Instant Quote)

The Solution for Waterlogged Boat & Outdoor Cushions

Tired of cushions that soak up water, stay wet and start to smell?

Reticulated foam—also known as dry fast foam—is specifically designed to solve that problem. Unlike standard foam that traps moisture, this open-cell foam allows water to drain straight through, making it the go-to choice for:

• Boat cushions exposed to spray and rain
• Outdoor seating left outside
• Garden furniture cushions that won’t dry properly
• Replacement foam for water-damaged seating

If you’re looking for foam that doesn’t hold water and dries quickly, this is the correct material.

All foam is cut to size for a precise fit, so you can properly replace your existing cushion inserts.

Why Standard Foam Fails (And This Doesn’t)

Most cushion foam acts like a sponge—once it gets wet, it stays wet.

Reticulated foam is different:

• Water drains straight through the foam
• Air circulates freely for rapid drying
• Helps prevent mould, mildew and damp odours
• Maintains performance even in wet environments

This is why it’s widely used as:

• Boat cushion foam replacement
• Quick drying foam for outdoor cushions
• Drainage foam for seating
• Breathable foam for damp environments

Marine Cushion Foam – Built for Boats & Wet Conditions

If you’ve got boat cushions that hold water, this is the fix.

Used across:

• Cockpit seating
• Flybridge cushions
• Deck sun pads and loungers
• RIB and open boat seating
• Cabin seating in damp environments

Why it works for marine use:

• Handles repeated exposure to water
• Drains instantly instead of absorbing moisture
• Reduces long-term damp and mould issues
• Ideal for replacement boat cushion foam inserts

For best results, pair with water-resistant marine fabric and breathable cushion covers.

Outdoor Cushion Foam – Stops Garden Cushions Getting Waterlogged

Perfect for replacing foam in:

• Garden sofa cushions
• Patio seating
• Outdoor bench cushions
• Sun loungers
• Commercial outdoor seating

Key benefits:

• Quick drying after rain
• Prevents cushions becoming heavy and saturated
• Improves airflow inside covers
• Extends the lifespan of outdoor seating

If your cushions are constantly damp, this is the upgrade that fixes it.

Cushion Covers Must Be Breathable to Let Water Drain

Reticulated foam only works properly if water can escape the cushion.

If you use fully waterproof or sealed cushion covers, water will become trapped inside the cover—even though the foam itself allows drainage.

For best performance:

• Use breathable or water-resistant fabrics, not fully sealed materials
• Ensure cushions have ventilation panels, mesh bases or zip gaps
• Avoid airtight covers that prevent airflow
• Allow water to drain out and air to circulate through the cushion

Why This Matters

• Trapped water leads to slow drying and damp cushions
• Lack of airflow can still cause mould and mildew
• Even fast-draining foam needs air movement to dry properly

Best Practice Setup

For a fully effective outdoor or marine cushion:

• Reticulated foam (fast draining core)
• Breathable or marine-grade fabric
• Ventilated cushion design (mesh or airflow gaps)

This combination ensures water drains quickly and cushions dry as intended.

Looking for Foam That Doesn’t Hold Water?

This product directly answers searches like:

• foam that doesn’t absorb water
• outdoor cushion foam that drains
• quick dry foam for cushions
• foam for boat cushions that won’t go mouldy
• replacement foam for wet cushions
• breathable foam for outdoor seating

This is reticulated foam cut to size.

Is Reticulated Foam Waterproof?

No—and that’s exactly why it works.

Instead of trapping water, it:

• Allows water to pass straight through
• Dries quickly through airflow
• Prevents moisture build-up inside cushions

Waterproof foam would hold water internally. This avoids that completely.

Understanding PPI (Choosing the Right Foam Grade)

• 10 PPI – maximum drainage, coarse structure
• 30 PPI – best for seating and cushions
• 45 PPI – finer filtration applications

For most boat and outdoor cushions, 20–30 PPI is the correct choice.
