The Signatory Superb marks the entry point into Vispring’s two-layer spring design, pairing hand-opened long-stranded Austrian Moosburger® horsetail with hand-teased Real Shetland Wool blended with cashmere. This refined combination shapes both the feel and the thermal behaviour of the sleep surface, delivering a balanced blend of support and luxurious comfort that remains distinct from a single-filling approach.
The ticking blends wool, silk, and viscose for breathability and softness to condition the microclimate from first contact. The upholstery unfolds in layers: British fleece wool for resilience and moisture regulation, followed by the resilient horsetail fibers, then Real Shetland Wool with cashmere for a finer transition that moderates temperature. A core mix of Real Shetland Wool and organic cotton adds body and absorptive capacity, while a two-layer hand-nested, vanadium steel calico pocket spring system with 3,296 springs in King size adapts independently to weight and movement. The border, coir and wool upholstered, is reinforced by four rows of hand side-stitching to extend the usable surface, and every tuft point is secured with woollen tufts and twine to maintain depth and stability over years of use.
