The Signatory Superb mattress blends luxurious natural fillings with expert craftsmanship to deliver exceptional comfort and support through the night. Generous layers of Shetland wool, organic cotton, Mooseburger horsetail, and cashmere are hand-tufted into a durable ticking, creating a plush yet resilient sleeping surface. Supported by two rows of Vanadium steel hand-nested pocket springs, this mattress offers customizable firmness options—soft, medium, firm, or extra-firm—so you can tailor the feel to your preference. King sizes are available with split firmness for truly personalized comfort at the pillow and toe edges.
Designed for long-lasting performance, the construction features two-layer hand-nested calico pocket spring systems with a high spring count, paired with natural, breathable upholstery materials and a refined ticking. The combination of premium natural fillings, hand-tied woollen tufts, and breathable borders contributes to steady support, even weight distribution, and a luxurious, cradle-like feel. Availability includes varied heights to fit different bed frames and personal sleeping styles.
