Wake up feeling completely refreshed with the Harper by GhostBed®, a 12” hybrid mattress designed for cool, responsive comfort. Strategic layers of 3 different types of foam along with 8” pocketed coils create a balanced, supportive feel that’s perfect for back, side and stomach sleepers alike. The individually wrapped coils keep motion transfer to a minimum, while reinforced edges contribute to a larger (and more stable) sleeping area. Plus, 1.5” inches of cooling, gel-infused memory foam gently contours your pressure points and draws heat away from you as you sleep. The Harper by GhostBed® is proudly made in the USA with CertiPUR-US® certified materials and comes with an industry-leading warranty.
