The Sonno Versa (2003) brings unprecedented versatility to shared beds. It comprises two individual reversible mattress halves placed side by side snugly inside a cover made of CoolMax®, a patented ventilating fabric that wicks away moisture to help the body maintain an ideal temperature while sleeping. Each half of the mattress has a firm side and a soft side, allowing both sleepers to suit their needs. (The seam between mattress halves is undetectable.) Unlike other memory foam mattresses, the Sonno immediately adjusts to suit your body position without requiring a warm-up period, supporting your weight whenever you roll. The result is a feeling of floating, which allows you to rest naturally, isolated from vibrations and movement that interrupt sound sleep. Free of metal coils that loosen and shorten the life of most mattresses, the Sonno Versa Mattress never needs to be flipped or rotated. Ships rolled in a compact tube for easy handling and quickly expands to full thickness, ready for use on a well-ventilated platform or slat bed. The mattress should be positioned label side up. Backed by a 15-year warranty. Made in Italy.
