Our PIANOMAT foam is not visible at first sight, which does not mean it is not useful.  You walk on it every day without even knowing it because it is concealed as an underlay under carpets. It has the superior properties of a soft foundation that gives a feeling of pleasant softness. It also provides excellent soundproofing for high acoustic comfort. It may also come as a surprise that PIANOMAT foam is an extremely environmentally friendly recyclable material.
