It combines horsetail, Real Shetland Wool, silk, mohair, organic cotton, and a viscose and cotton ticking with a two-layer hand-nested pocket spring system (3,496 springs in King). This blend aims to balance buoyant support with breathable, moisture-transporting surfaces, while keeping the feel stable over time.
It suits sleepers who want a responsive, well-supported surface with natural fillings and a high spring count for edge-to-edge sleep. The combination of materials is designed to regulate temperature and maintain comfort without relying on synthetic foams.
The ticking and natural fillings are chosen to manage moisture and promote breathability, which helps with warmer nights. The support layers are designed to stay stable over years of use, making it suitable for varied seasonal temperatures.
Its two-layer pocketed spring system and premium upholstery are designed for a firm yet cushioned feel across the sleep surface, making it suitable for traditional bed frames and rooms that prioritize edge-to-edge support and long-term structure.
Hand-tied woollen tufts lock each filling layer in place, while the side-stitching helps preserve the edge and full surface. The combination of natural fillings and a high-spring-count pocket system is intended to resist compression and maintain the original feel over time.
It blends horsetail with Real Shetland Wool and silk/mohair in a hand-nested pocket system with high spring count, plus woollen tufts and side-stitching to maintain shape. This focused natural-fill construction aims for buoyant responsiveness and sustained comfort.
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.
