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 mixed with cashmere. This pairing shapes both the feel and the thermal behavior of the sleep surface, offering a nuanced balance of softness, support, and breathability that none of the fillings could achieve alone.
The ticking is crafted from wool, silk, and viscose to condition the microclimate from first contact, while the upholstery layers build from resilient British fleece wool for moisture regulation, to the long, crimped horsetail that resists compression, and finally a finer layer of Real Shetland Wool blended with cashmere for a comfortable transition. A core blend of Real Shetland Wool and organic cotton adds body and absorptive capacity, complemented by a two-layer vanadium steel calico pocket spring system with 3,296 springs in a King size that respond independently to weight and movement. The border features coir and wool, secured by four rows of hand side-stitching to extend the usable surface and preserve the profile, with hand-tufting in woollen yarns compressing the layers into a stable depth at every tuft point.
