Safe PU Foam Material

U foam, a safe material also used in medical hydrocolloid dressings, offers excellent aging and water resistance, as well as superior resilience. Its shape remains stable even after prolonged and frequent use, making it widely used for bedding mattresses. The perforated surface forms an air layer that effectively blocks ground cold.

2-Way Valve

When the valve is opened, the internal foam self-expands, allowing for easy use without additional air inflation. Additionally, the 2-way valve prevents air from escaping during extended use and ensures no air leaks even if the valve is accidentally opened.

Compact Packing Size

This is a roll-up type product—simply deflate, roll it up, and store. Its compact size won’t take up much space, and the dedicated strap ensures a secure finish.

How to Use the 2-Way Valve

Air Inflation

When the outer valve is opened, self-inflation begins. A thin inner membrane inside the cap prevents the injected air from escaping.

2-Way Valve

When the valve is closed, the double-seal structure prevents any air leakage during use.

Air Release

After opening the valve, pull out the inner air flap and roll the mat for easy deflation. Once the air is completely released, place the inner flap back inside and close the valve.
