MULE Mats - Four Wheel Camper Mattress Upgrade

Upgrade your comfort on the road with the MULE Mat, a premium replacement mattress designed specifically for all Four Wheel Camper (FWC) models. Built to offer real support and long-lasting durability, the MULE Mat is a major step up from standard camper mattresses.

Key Features:

• 4" dual-layer foam – provides proper support (not memory foam, which sinks and lacks firmness).

• Dual-sided textiles – soft, durable vinyl on one side / high-quality fabric on the other. Choose your preferred feel.

• Perfect fitment – sized to match each FWC model exactly, with 1" added thickness for extra comfort.

• Color – sleek black/dark grey design.

• Vacuum packed for shipping – must be opened within 14 days of arrival to avoid damage (warranty void if not opened).

• Lead time – up to 4 weeks production once your order is placed.

Whether you’re a weekend traveler or full-time adventurer, the MULE Mat ensures every night in your camper feels like home.
