The Signatory Superb mattress blends luxurious natural fibers with meticulous craftsmanship to deliver exceptional comfort and long-lasting support. A generous mix of Shetland wool, organic cotton, Moosburger horsetail, and cashmere is hand-tufted into the ticking, creating a soft, breathable surface that cradles the body. Two rows of Vanadium steel hand-nested pocket springs provide responsive support, while multiple firmness options—soft, medium, firm, or extra-firm—allow you to tailor your sleep experience. King-size configurations also offer split firmness for personalized comfort across partners.
Designed with premium materials and careful engineering, this mattress emphasizes durability and consistent comfort night after night. The internal construction features a two-layer hand-nested calico pocket spring system and an exquisite upholstery of natural fillings, including British fleece wool, hand-opened Austrian Moosburger horsetail, and real Shetland wool blended with cashmere. A high-quality ticking, hand-tied woollen tufts, and robust borders further enhance longevity, while careful dimensioning ensures a comfortable overall depth and height across standard and tall profiles.
