The Signatory Superb mattress blends luxurious natural fibers with expert craftsmanship to deliver exceptional comfort and support. Generous layers of Shetland wool, organic cotton, Mooseburger horsetail, and cashmere are carefully filled and hand-tufted, ensuring durability and a consistently plush sleeping surface. Supported by two rows of Vanadium steel hand-nested pocketed springs, this mattress offers responsive support and comes in a choice of firmness from soft to extra-firm, with split firmness available for king sizes to suit individual sleep preferences.

Designed for lasting comfort, the construction emphasizes premium materials and meticulous detailing—from hand-tied woollen tufts and fine ticking to a robust border and vented, breathable structure. The mattress sits on a solid timber divan frame and is offered in multiple heights, providing a refined, bespoke sleeping solution that adapts to different sleeping styles while maintaining superior support throughout the night.
