A 100% pure open-cell latex foam core with 5 different support zones, the right support for every part of the body in any position and the guarantee that the spine will assume a correct position constitute the biomechanical properties of this mattress. It has a thermo-regulating filling with a pure wool layer for the winter side and pure cotton for the summer side, both with a hypo-allergenic thermal fibre support that ensures correct temperature control in any season of the year. The anti-bacterial and anti-dust mite Sanitized treated fabric is a natural barrier against dust mites and the proliferation of microorganisms that are the principal cause of allergies.
