The Signatory Superb mattress blends natural fibers for a sumptuous, cradle-like sleep. Generous fills of Shetland wool, organic cotton, Mooseburger horsetail, and cashmere create a premium, breathable sleeping surface, with a hand-tufted ticking that ensures durability and consistent comfort. Two rows of Vanadium steel hand-nested pocket springs provide robust support, available in soft, medium, firm, or extra-firm firmness, with king sizes offered in split firmness to accommodate personal preferences.
Designed for luxury and longevity, this mattress uses a two-layer hand-nested calico pocket spring system and premium natural fillings—from British fleece wool to hand-opened horsetail and blended wool with cashmere. The upholstery emphasizes natural materials, refined finishing with hand-tied woollen tufts, and a high-quality ticking or upholstery fabric. The overall construction delivers a balanced feel with precise spring tension and careful layering to support the body through the night.
