The Herald Superb is available in standard mattress sizes, with King size described as having 1,716 Vanadium steel springs in the full system. King can be specified in split firmness for partners with different preferences, helping you choose a fit that matches your bed and sleep style.
It uses three rows of hand-nested calico pocket springs with individually nested coils, designed so each sleeper’s movement doesn’t affect the other. The spring system is paired with natural fibre upholstery for a clean, breathable feel and a clearly defined support under the surface.
The spring system uses Vanadium steel, chosen for fatigue resistance and consistent tension over years of use. The border is reinforced with wool and two rows of hand side-stitching to anchor the edge and protect the sleeping surface.
The upholstery layers are made from natural fibres, including bonded British fleece wool and cotton, plus blended wool and cotton. This combination helps regulate temperature, maintain loft, and prevent the filling from compressing unevenly over time.
Four tension options are available at order: Soft, Medium, Firm, and Extra Firm. King sizes can be split for varying firmness, allowing partners to tailor support without compromising the spring system.
The Herald Superb elevates the Vispring experience with a deeper spring architecture, featuring three rows of hand-nested calico pocket springs that respond to individual movement while maintaining a clean, uncluttered upholstery. With tension choice as the primary variable, this design emphasizes precise comfort and long-term support, ensuring a balanced feel across all sizes.
In a King size, 1,716 Vanadium steel springs are individually nested in calico pockets so each coil moves independently, minimizing partner interference. The spring is paired with natural fibre upholstery—breathable wool and cotton—that regulates temperature and preserves loft, while the finest ticking and hand-tufted construction keep the surface even and durable. Enhanced features like side-stitching, reinforced borders, felt washers, and perimeter air vents work together to protect the spring edge and optimize airflow for nightly comfort.
