Crimson Underlay 11.4mm

Crimson Underlay is a high-quality underlay and at 11.4mm thick it gives the ultimate feel of luxury, sound reduction, and longer-lasting. Made of sponge rubber which doesn't disintegrate or flatter like other alternatives which allow it to outlast PU and Crumb rubber versions quite easily. The sponge part of its makeup allows it to give you a soft feel while keeping its resilience and returning to its original state.
