The Signatory Superb introduces Vispring’s two-layer spring architecture, pairing hand-opened long-stranded Austrian Moosburger® horsetail with hand-teased Real Shetland Wool blended with cashmere. This deliberate combination shapes both the feel and the thermal behavior of the sleep surface, delivering a responsive, breathable experience that a single filling cannot achieve on its own.
The ticking blends wool, silk, and viscose for soft, breathable contact, while the upholstery layer sequence emphasizes resilience, temperature regulation, and loft. British fleece wool provides moisture management, followed by the long, crimped horsetail to resist compression and maintain consistent loft. A refined mix of Real Shetland Wool and cashmere offers a gentle, temperature-moderating transition, with Real Shetland Wool and organic cotton adding body and absorption. The spring system features two layers of hand-nested, vanadium steel calico pocket springs—3,296 in a King—providing independent weight and movement response. The border, reinforced with coir and wool and four rows of hand side-stitching, extends the usable sleep surface and preserves the upholstery profile, while hand-tufting binds the filling into a stable, consistent depth at every tuft point.
