The Signatory Superb marks the entry into Vispring’s two-layer spring architecture, blending hand-opened long-stranded Austrian Moosburger® horsetail with hand-teased Real Shetland Wool and cashmere to shape both the feel and thermal performance of the sleep surface. The ticking combines wool, silk, and viscose for breathability and softness from first contact, while the upholstery layers beneath deliver resilience, moisture regulation, and a refined transition that moderates temperature without trapping heat.
Inside, a core of British fleece wool, hand-opened horsetail, and Real Shetland Wool blended with cashmere creates a superior, breathable interface. A final blend of Real Shetland Wool and organic cotton adds body and absorptive capacity, while two layers of hand-nested, vanadium steel calico pocket springs—3,296 in a King—respond independently to weight and movement for continuous support. The border, coir and wool-backed, is secured with four rows of hand side-stitching to extend the usable surface and preserve upholstery profile, with hand-tufted woollen tufts and twine compressing the filling to a stable depth at every tuft point.
