This mattress uses a blend of horsetail, Real Shetland Wool, silk, and mohair with organic cotton and viscose-cotton ticking. The combination is designed for buoyancy, warmth, and moisture management while maintaining a stable, supportive base.
It suits sleepers who want a responsive, edge-to-edge comfortable surface with a buoyant feel and good thermal regulation, especially those who appreciate natural fibers and a high spring count for minimized movement transfer.
It uses a two-layer hand-nested calico pocket spring system with Vanadium steel and 3,496 springs in King, designed to respond to individual body weight and limit pressure transfer, while four rows of hand side-stitching helps keep the edge firm.
The viscose and cotton ticking aids moisture movement and airflow, helping keep the surface cool. The natural fillings and wool components also contribute to temperature regulation across different sleep phases.
Yes, the high spring count and individually responsive springs help minimize partner disturbance and maintain support across the sleep surface.
The Sublime Superb blends natural fillings like horsetail and Shetland wool with silk and mohair, offering buoyant, warm support that adapts to weight without bottoming out, rather than relying on synthetic foam for contouring.
The Sublime Superb introduces South American horsetail to the Superb line, blending it with Real Shetland Wool to form a filling combination that manages heat through the night while resisting compression over years of use. The sleep surface is covered in a viscose and cotton ticking: viscose draws moisture away from the body, cotton allows air to circulate, and together they keep the surface cool without the need for synthetic materials. Beneath the cover, British fleece wool provides an immediate, responsive cushion that adjusts to body weight without bottoming out. The horsetail and Real Shetland Wool blend that follows works differently — horsetail is coarse and springy by nature, giving the filling layer a buoyancy that neither wool alone nor synthetic foam can replicate, while the Shetland wool moderates its texture and adds further thermal regulation. Silk and mohair sit within the upholstery stack as well, both fine-fibred materials that contribute softness and warmth retention in proportion. Organic cotton rounds out the filling, lending a firm, stable base to the upholstery layers above it.
The spring system is a two-layer, hand-nested calico pocket construction using Vanadium steel: 3,496 springs in a King size respond individually to movement, so pressure at one point does not transfer across the mattress. Four rows of hand side-stitching hold the border firm and square, maintaining the full sleep surface to the edge. Hand-tied woollen tufts drawn through the full depth of the mattress anchor each filling layer in place, preventing migration and preserving the original feel of the upholstery over time.
