The Signatory Superb uses a dual-layer vanadium steel pocket spring system with thousands of individually responding springs, a reinforced border with coir and wool, and hand-tufted woollen tufts to secure layers and maintain edge-to-edge support for years of use.
King size is listed as having 3,296 springs in the core, with the two-layer spring architecture designed to provide independent support across the sleeping surface.
It suits sleepers who want targeted support with resilient edge-to-edge performance and a breathable, thermally regulated surface thanks to natural fibers like horsetail, wool, and cashmere.
The breathable ticking and moisture/temperature regulation from wool and silk blends support a balanced microclimate, making it suitable for a range of climates and climates-based comfort preferences.
It uses natural materials and a high-loft core designed for consistent depth and support; expect a responsive yet supportive feel due to the two-layer spring system and wool/cashmere blend in the comfort layers.
The edge-to-edge support and stable depth across tuft points help maintain a uniform sleeping surface alongside compatible bed frames and bedding setups.
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 to shape both the feel and thermal behavior of the sleep surface. The ticking blends wool, silk, and viscose for breathability and softness at the first point of contact, while the upholstery layers work in concert to regulate moisture and temperature across the night.
Beneath the surface, the core combines resilience and steady loft: British fleece wool for moisture regulation, long-crimped horsetail to resist compression, and a refined transition layer of Real Shetland Wool blended with cashmere. A Real Shetland Wool and organic cotton blend adds body and absorption, complemented by a two-layer hand-nested vanadium steel calico pocket spring system with thousands of individually responding springs. The border is reinforced with coir and wool, four rows of hand side-stitching, and hand-tufted woollen tufts to secure the layers and maintain a stable, edge-to-edge sleep surface for years of use.
