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 the sleep surface’s feel and thermal behavior beyond what a single filling can achieve. The ticking combines wool, silk, and viscose for breathability and softness, conditioning the microclimate from first contact and guiding comfort through the night.
Underneath, the upholstery layers build resilience and temperature regulation: British fleece wool for moisture management, followed by the durable, loft-preserving Moosburger® horsetail, and a refined blend of Real Shetland Wool with cashmere for a softer, more nuanced transition. A core of Real Shetland Wool and organic cotton adds structure and absorption, while the two-layer hand-nested vanadium steel calico pocket springs—3,296 in a King size—respond independently to weight and movement for continuous support. The border is finished with coir and wool, reinforced by four rows of hand side-stitching to extend the usable sleep surface, and the entire mattress is hand-tufted with woollen tufts and twine to lock the layers in place over years of use.
