The Sonno Versa (2003), exclusive to DWR, brings unprecedented versatility to shared beds. Designed as two separate, individual mattresses, both are contained snugly inside a single CoolMax mattress cover (twin is a dual-surface single mattress). CoolMax is a two-sided gradient fabric that wicks moisture away to help the body maintain an ideal temperature while sleeping. Each half of the 9'-high mattress is constructed with a firm side and a soft side, allowing sleepers to adapt the surface according to their needs. The Versa's memory foam provides proper support for the entire body, creating the feeling of floating. The result is increased blood circulation and spinal alignment, fewer aches and pains, and a greater sense of tranquility upon waking. The seam between the mattresses is undetectable, and all Sonno mattresses ship rolled in a compact tube ready for use on a well-ventilated platform or slat bed frame. A 15-year limited warranty guarantees lasting satisfaction. Made in Italy.
