• 100% HR+visco 2.50 CMTS 1 SIDE • Core: high resilience HR block. Side 1: visco-graphene, 95% improvement in air circulation compared to traditional viscoelastic foam. When a Coolgraph foam is compressed, the graphene particles absorb the heat and transmit it among themselves due to their proximity. Foams created with this technology have open cells, thus creating space for heat to dissipate quickly (2.5 cm visco-graphene and super soft on the top side). Side 2: high-quality hypoallergenic fiber that offers great comfort and softness, providing firm and adaptable support. The Stretch fabric is of high quality and weight with anti-mite treatment. Approximate height 23 cm. 2-year quality and handcrafted in Spain.
