Problem with moisture causing mildew & odour under your mattress?
We can no longer source Hypervent so have found a very similar product - Mattvent. It is the most practical prevention of dampness under foam mattress in boats, motorhomes, caravans & even at home.
Extruded three dimensional black mesh. It provides a space for air to pass under your mattress to help prevent condensation or moisture build-up & help with drying.
I am doubling the Mattvent under my 3m x 3m outdoor daybed mattress. Because it is so large & heavy, I would like it to have extra space underneath. I will lay the two layers at 45° to each other.
