The Signatory Superb mattress blends luxurious natural fibers to cradle you in lasting comfort. Generous layers of Shetland wool, organic cotton, Moosburger horsetail, cashmere, and other natural fillings are hand-tufted into a durable ticking, delivering a soft to supportive feel that remains consistently plush night after night. With two rows of Vanadium steel hand-nested pocket springs, this mattress provides exceptional support and motion separation, and is offered in a choice of firmness levels—from soft to extra-firm, including split firmness for king sizes to suit individual preferences.
Crafted with attention to detail, the mattress features two-layer hand-nested calico pocket spring construction and a premium upholstery that emphasizes natural fillings, British fleece wool, and carefully selected horsehair blends. The result is a refined, breathable sleeping surface with reinforced borders, four-row hand side-stitching, and air vents, designed to maintain comfort, support, and durability over the long term. Available in multiple heights to fit your bed setup and room style.
