Fiberluxe, a combination of athermal fibre and a layer of HR polyether, provides extra-soft comfort and ensures continuous airflow while sleeping so it breathes better. If you share a bed, the Confort Pocket System allows the spring mattress to adapt point by point to the shape of each sleeper and create separate sleeping areas. Versalles is a flippable mattress with four embroidered handles, making it easier to move, with medium firmness and high breathability. All Sema mattresses come with our permanent, effective dust-mite treatment B.A.T. (dust-mite treatment).
