Airmat AG+ 8mm Moisture Reducing Spacer – Stop Damp & Condensation Under Mattresses

Airmat AG+ is a moisture reducing spacer layer designed to stop condensation forming under mattresses and cushions in campervans, caravans, boats, pop-top roofs, and roof tents.

It creates a continuous airflow gap between the mattress and the base, helping prevent damp, mould, and musty conditions in confined environments.

Why You Need It

If your mattress or cushions sit on a solid surface such as wood, metal, or fibreglass, moisture will build up underneath.

This leads to:

• Damp patches under the mattress
• Musty smells in enclosed spaces
• Mould forming over time
• Foam breaking down prematurely

Airmat AG+ addresses the root cause by allowing air to circulate beneath the mattress, rather than trapping moisture.

How It Works

Airmat AG+ is a 3D breathable spacer fabric that sits between your mattress and its base.

It:

• Creates a constant airflow gap
• Allows moisture to escape
• Reduces condensation build-up

This breaks the cycle of trapped moisture that causes damp and mould.

Silver AG+ Anti-Bacterial Protection

Airmat AG+ incorporates Silver AG+ technology, which uses silver ions to help inhibit the growth of bacteria.

This helps to:

• Reduce odours caused by damp conditions
• Maintain a cleaner sleeping environment
• Improve hygiene in enclosed spaces

Widely used in hygiene-sensitive applications, it is particularly suited to campervan and marine environments where moisture is unavoidable.
