The Tiara Superb is the entry point into Vispring's hand-teased horsetail fillings, placing South American horsetail at the centre of the upholstery layer where it does its most consequential work. The ticking is woven from wool and viscose, a surface that breathes without feeling cool, carrying warmth away from the body gradually rather than in pulses.

Beneath it, the filling sequence works from the outside in: blended Real Shetland Wool and organic cotton forms the first and final upholstery layer, providing immediate softness and wicking moisture at the point of contact. The middle layer is hand-teased South American horsetail blended with Real Shetland Wool, its hollow fibres retaining resilience through years of compression and releasing heat steadily through the night. The spring system is a two-layer, hand-nested calico pocket construction built from Vanadium steel, with 2,856 individually pocketed springs in a King size; each spring responds to point pressure without transferring movement across the surface, so two sleepers disturb each other less. The border is upholstered with coir and wool for a defined, supportive edge, then locked with three rows of hand side-stitching that fix the spring perimeter in place and prevent the border from softening unevenly over time. Woollen tufts, hand-tied with twine, compress the filling layers at fixed intervals, holding the upholstery in place and maintaining an even depth of approximately 9.1 inches across the full sleep surface.
