An innovative solution designed to relieve tension in the spine and promote a natural opening movement of the thorax, thanks to the anatomical pressure exerted by the special longitudinal contouring of the upper layer in elastic and breathable foam. The structure of the panel provides support with its wave contouring with high-density foam micro-springs that adapts perfectly to the weight of the body. Contributing to its comfort is the material of the top layer with its cooling, soothing, emollient and anti-inflammatory properties.
