The Devonshire uses a single tier of 1,716 hand-nested vanadium steel coils with wool layers for air flow and temperature regulation, giving independent support with a balanced, traditional feel suitable for those who value structured cushioning and long-lasting support.
It suits sleepers who appreciate handcrafted construction and classic, durable pocket-sprung support, ideal for traditional bedrooms where a firm, responsive surface is preferred.
Its edge-to-edge stability, hand side-stitching, and year-after-year shape retention make it well-suited for master bedrooms or guest rooms that aim for lasting comfort and a timeless look.
Key features include the hand-nested calico-pocketed coils for independent support, wool layers for temperature management, and hand-tufting with felt washers to prevent filling migration and maintain a smooth surface.
The four tension options (Soft, Medium, Firm, Extra Firm) and king-size center split allow partners to choose different firmness preferences while still sharing a single mattress.
The ticking is woven from wool and viscose, a pairing that keeps the cover soft against the skin while the viscose adds durability to a fabric subjected to decades of use. Beneath it, a layer of hand-teased Devonshire fleece wool provides the immediate give — teasing opens the fibres so air moves freely through them, which moderates temperature through the night rather than trapping it. A further layer of British fleece wool beneath that adds depth and resilience, so the surface does not compress unevenly over time.
The spring system consists of a single tier of 1,716 hand-nested, calico-pocketed Vanadium steel coils in a King size. Each spring sits within its own calico pocket and responds to weight independently, so two sleepers of different builds are supported without interference between them. Vanadium steel holds its tension longer than standard carbon steel, which is why Vispring applies it across the range. The Devonshire is available in four tension options — Soft, Medium, Firm, and Extra Firm — and King sizes can be split across the centre for partners with different preferences. Two rows of hand side-stitching secure the border coils to the mattress edge, keeping the sleeping surface firm and consistent to the very perimeter. Hand-tufting with felt washers anchors the fillings in place at regular intervals, preventing any lateral shift that would otherwise create unevenness after years of use.
