One of the biggest battles on a boat is fighting moisture due to climate fluctuations. Our mattress foundation is a 3/4″ spun polymer that is bonded to a breathable fabric. The foundation is cut to fit your mattress size and shape and keeps your mattress 3/4″ off the platform, allowing air to circulate. The foundation can not be felt while laying on the mattress and it is maintenance free. An effective and cost efficient way to keep your mattress dry and healthy.
