The Sublime Superb is part of the high-end Sublime line and uses a two-layer hand-nested calico pocket system with Vanadium steel springs, complemented by natural fillings like horsetail, Real Shetland Wool, silk, mohair, and organic cotton for a supportive, breathable sleep surface.
Place it on a suitable bed frame that supports a standard king size (3,496 springs in that size) and allow the top layer to breathe. The cover combines viscose and cotton to wick moisture and promote airflow, contributing to a cooler surface during sleep.
It uses horsetail and Real Shetland Wool for buoyancy and thermal regulation, silk and mohair for softness and warmth retention, and organic cotton for a firm base. The woollen tufts help prevent filling migration, preserving the feel over time.
It uses a two-layer hand-nested pocket spring system with 3,496 springs in a King size, plus a filling blend of horsetail and Shetland wool that combines buoyancy with temperature control, reinforced by hand side-stitching to keep the sleep surface edge-to-edge.
The combination of viscose-cotton cover, wool-based fillings, and natural fibers aims to regulate temperature and moisture, making it suitable for varied climates and seasons.
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.
