The Formula Evolution mattress combines technology, comfort, and well-being to provide high-quality sleep every night. The core consists of individually pocketed stainless steel springs, fully independent from each other, capable of responding precisely to every body movement while providing differentiated and silent support. The springs are enclosed in a waterfoam perimeter box, designed to maintain stability, durability, and long-lasting performance. On the top and bottom sides, the spring box is covered with two layers of water-foamed, thermo-sensitive memory foam with open-cell structure, offering ergonomic properties. Medium firmness ensures correct spinal alignment, supporting orthopedic benefits and reducing discomfort or pain caused by incorrect sleeping positions. The pocket spring structure, combined with open-cell layers, guarantees high breathability and continuous airflow, preventing moisture accumulation and maintaining a stable temperature in all seasons. The mattress is covered with safe, certified fabrics suitable for the whole family. The internal padding is 250 g/m² wadding, and the external cover is hypoallergenic, anti-dust-mite, and antibacterial 210 g/m² fabric. Highly breathable 3D side inserts further enhance ventilation. Four side handles make moving the mattress practical and easy. The mattress is shipped folded, rolled, and vacuum-packed for hygiene and easy transport
Clean the surface with a damp cloth and mild detergents; avoid bleach and aggressive products; regularly air the mattress and rotate it head-to-foot and top-to-bottom to preserve its shape, firmness and comfort over time.
