The new GhostBed Mattress is comprised of five unique layers. The Ghost Ice cover is one of the coolest on the market giving you an immediate cool feel. The plant-based, sustainably sourced, soy Bio Foam is naturally more breathable than conventional memory foam. The two individual convoluted layers create air channels that enhance the faster heat dissipation of the Bio Foam. Gel-infused memory foam provides amazing pressure relief, contouring to the body for ideal support while reducing tossing and turning, as well as aches and pain for a deeper night’s sleep. The high-density base layer is durable, providing years and years of ideal support and longevity. Wake Up Sweat-Free The cool-to-the-touch Ghost Ice cover acts like instant air conditioning with 2" of gel memory foam that absorbs heat and transfers it away from you as you sleep. Opt for Non-Toxic Make the safe choice for you and your family with eco-friendly foam that’s manufactured without the traditional petroleum chemicals found in other memory foam mattresses. Enjoy a Pain-Free Morning The high-density foam core helps keep your spine aligned, while the two contouring Ghost BioFoam layers ease aches and pains.
