No. 3 introduces Pillow Top. It’s an extra layer of memory wool (60% polyester, 40% wool) that’s added to the mattress surface for an incredible depth of comfort. Beneath that, No. 3 holds 1400 pocketed springs and is filled with even more natural materials – cotton, wool, soft bamboo, fleecy alpaca and silky pashmina. Elsewhere, the hand-tufted filling keeps the mattress at its best and we add further layers of wool for even more comfort. It’s all finished with Belgian Damask ticking with a viscose that gives the mattress surface an incredibly silky feel.
