Handmade in the UK exclusively for Heal’s, at the centre of the Premium Sleep Silk Mattress sits 1400 pocket springs each of which has been hand sewn and nested into a honeycomb structure to move independently from one another responding to the natural contours of the body and movements during the night. The springs are then topped with a luxurious cashmere and silk pad, which helps to equalize temperature, as well as hand-teased mohair and merino wool for a supportive yet soft feel. On top of these rest breathable layers of lambswool and cotton, which help wick away moisture from the body during the night as well as regulate body temperature for a fresh night’s sleep all year round. Available in a choice of soft, medium or firm tension, the Natural Sleep Silk mattress is filled, tufted and stitched entirely by hand with Heal’s ticking providing the finishing touch.
