Our Earth Friendly Green Line mattresses are unlike any others available on the market today. A dramatic departure from traditional foam and steel innersprings, our eco-friendly mattresses are hypoallergenic, won't produce airborne mold or bacteria particles, and are made from safe, non-toxic, environmentally friendly materials. Our Green Earth slumber set is made of natural bamboo; our Green Karma slumber set is made with flameproof Indura Performance Fibers (IPF). Both mattresses are extremely durable, lushly comfortable, and exceed industry standards for safety and performance.
