The Signatory Superb introduces a refined two-layer spring architecture, marrying hand-opened Austrian Moosburger® horsetail with hand-teased Real Shetland Wool blended with cashmere to shape both the feel and the thermal behavior of the sleep surface. The ticking is woven from wool, silk, and viscose—not for display, but for breathability and softness that begin conditioning the microclimate at first contact, while the layered upholstery supports durability and consistent loft over time.
Beneath the surface, a thoughtful progression of materials drives performance: British fleece wool for resilience and moisture regulation, long crimped horsetail to resist compression, and a finer transition layer of Real Shetland Wool blended with cashmere to moderate temperature without trapping heat. A core of Real Shetland Wool and organic cotton adds body and absorptive capacity, complemented by a two-layer, hand-nested vanadium steel calico pocket spring system with 3,296 springs in King size that respond independently. The border is reinforced with coir and wool, anchored by four rows of hand side-stitching to extend the usable sleep surface, while woollen tufts and twine compress the filling layers into a stable depth at every tuft point.
