The Signatory Superb represents the entry point into Vispring’s two-layer spring architecture, blending 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 refined balance of support and comfort that a single filling cannot duplicate.

The ticking is woven from wool, silk, and viscose to prioritize breathability and softness from the first touch. The upholstery layers build in sequence: British fleece wool for resilience and moisture regulation, followed by the hand-opened Austrian horsetail to resist compression over time, then Real Shetland Wool blended with cashmere for a finer, softer transition that moderates temperature. A core of Real Shetland Wool and organic cotton adds body and absorptive capacity, while the two-layer hand-nested vanadium steel calico pocket springs—3,296 in a King—respond independently for continuous support. The border uses coir and wool, anchored by four rows of hand side-stitching to extend the usable sleep surface, and each mattress is hand-tufted with woollen tufts and twine to lock the filling layers in a stable, consistent depth at every tuft point.
