Suitable for those who want an ergonomic but at the same time breathable pillow. The viscoelastic foam with a "memory effect" has holes for better air circulation and conforms to the shape of the body without any compression. The technological three-dimensions net, covering the memory foam, ensures the air circulation. The 3D net is ecological, fire retardant, insect repellent, anti-mold and anti-allergenic. Even the optional pillow case, removable and washable, contains the same 3D net of 3 mm, thus raising the standard of hygiene.
