The Signatory mattress combines cashmere, real Shetland Isle fleece wool, and long-stranded horsetail in a dual-layer pocket spring construction for substantial comfort and support. Its 1.32mm wire springs, 50mm in diameter, are sewn into individual calico pockets and hand-formed into a honeycomb-nested unit, providing consistent pressure distribution across the sleep surface. Four rows of genuine hand side-stitching reinforce the mattress border, while hand-tied woollen tufts and twine secure the fillings in place at 23cm depth. Eight horizontal handles aid repositioning, and air vents on all sides promote continuous airflow throughout the mattress.
