Every boater knows that condensation is an ongoing issue onboard any boat. In particular, boat beds are often built with solid wood or fibreglass bases, with mattresses snug against the hull. This becomes an issue when body heat and moisture disperses through the mattress and, with no ventilation, turns to damp, condensation and mould under the mattresses. DRY-Mat instantly alleviates this common issue by creating a permanent layer of air-flow under your mattress. Simply cut to shape, and place it under your mattress (no need to fix down) and let it do it’s job! It is more effective than slats, doesn’t degrade over time, is machine washable, and quick and easy to fit. DRY-Mat is a must have product for any boat. Just order the size equivalent to the widest part of your mattress / cushion and cut to shape with a good air of kitchen scissors.
