The Signatory Superb marks the entry into Vispring’s distinctive two-layer spring architecture, marrying hand-opened long-stranded Austrian Moosburger® horsetail with hand-teased Real Shetland Wool blended with cashmere. This pairing shapes both the feel and the thermal behavior of the sleep surface, delivering a balance of responsive support and refined softness that evolves with every night’s rest.
The ticking is woven from wool, silk, and viscose for breathability and a gentle initial contact, while the upholstery layers below build toward lasting comfort: resilient British fleece wool for moisture regulation, followed by the long, crimped horsetail for sustained loft, and a finer blend of Real Shetland Wool with cashmere to temper temperature without trapping heat. Completing the core are Real Shetland Wool and organic cotton for body and absorbent capacity, with a two-layer hand-nested vanadium steel calico pocket spring system delivering independent, zone-relevant support. The edge and border construction—coir and wool with four rows of hand side-stitching—enhance the usable sleep surface and preserve the upholstery profile through years of use, while woollen tufts and twine compress the fillings into a stable depth at every point.
