The Signatory Superb is available in standard mattress sizes; the King size model mentioned contains 3,296 springs. Larger sizes provide more surface area for independent support, while smaller sizes offer a more compact profile, with the same two-layer pocket spring design and loft-balancing fillings throughout.
It uses two layers of hand-nested pocket springs with independent support to respond to movement and weight across the sleep surface, plus a blend of horsetail and Shetland Wool with cashmere to balance loft and temperature.
It suits sleepers who value a responsive, temperature-balanced surface and a high-loft feel, with luxury fillings that shape both comfort and microclimate. It may be less ideal for those who prefer a very firm or a very soft, non-loft feel.
It features a two-layer pocket spring system with independently reacting springs and a specialized blend of long-stranded horsetail and Real Shetland Wool with cashmere, plus a breathable wool, silk, and viscose ticking aimed at conditioning the microclimate.
It has a durable border with coir and wool and is hand-tufted to maintain depth over time, so ensure your bed frame supports edge stability; the mattress is built to hold its loft and respond to movement due to its layered construction.
Given its luxury materials, hand craftsmanship, and temperature-managed comfort, it can appeal to sleepers seeking premium, long-lasting support and a premium sleep surface.
The Signatory Superb marks the entry into Vispring’s two-layer spring design, 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 beyond what a single filling can achieve. The ticking is crafted from wool, silk, and viscose for breathable softness that begins conditioning the microclimate at first contact, while the interior layers build a resilient, temperature-managed foundation.
Layer by layer, the upholstery blends British fleece wool for resilience and moisture regulation, then the long, naturally crimped horsetail to resist compression and maintain loft. Real Shetland Wool with cashmere provides a finer transition that moderates temperature, followed by a durable mix of Real Shetland Wool and organic cotton to add body and absorbency. The spring system features two layers of hand-nested, vanadium steel calico pocket springs with 3,296 springs in a King size, delivering independent support. The border is finished with coir and wool, reinforced by four rows of hand side-stitching to extend the sleep surface to the edge, while woollen tufts and twine compress the layers into a stable depth at every tuft point.
