No. 3 introduces Pillow Top. It’s an extra layer of memory 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 that gives the mattress surface an incredibly silky feel.
