The Signatory Superb ushers in Vispring’s two-layer spring architecture with a refined pairing of hand-opened long-stranded Austrian Moosburger® horsetail and Real Shetland Wool blended with cashmere. This combination shapes both the feel and the thermal behavior of the sleep surface, delivering a breathable, temperature-regulated response that evolves through nightly use.
The ticking blends wool, silk, and viscose for breathability and softness at first contact, while the upholstery core layers provide resilience, loft, and moisture regulation. With two layers of hand-nested vanadium steel calico pocket springs (3,296 springs in a King), each spring responds independently to weight and movement, supporting a continuous, edge-to-edge sleep surface that remains stable over time. Hand tufting, coir and wool borders, and anchor stitching reinforce the perimeter and help preserve the profile and comfort across seasons.
