The v9 Hybrid Mattress combines a classic innerspring system with modern latex foam to deliver the benefits of both constructions. This hybrid mattress allows sleepers to enjoy the perfect blend of sound support and contouring comfort through its advanced sleep technology. The knit cover, woven with Tencel yarn, wicks away moisture and is further enhanced by a cooling fabric treatment. Get a great night's sleep on a mattress that offers the best of both worlds.
