Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the Kingsbridge if you want traditional craftsmanship over foam and technology. The two-layer, hand-nested calico pocket spring construction means each spring moves independently, which you feel as precise, contouring support and less disturbance from a partner. The horsetail and Devonshire wool blend gives a soft yet supportive surface, while British fleece wool adds warmth and breathability, useful if you tend to overheat under synthetic materials. The medium-soft feel suits sleepers who like to settle into the surface a little, although anyone wanting a firmer platform should note the Kingsbridge is offered in multiple tensions, so check the tension before ordering. Yes, the price is high, but these are entirely natural fillings assembled by hand.
Key Features & what's inside
- British fleece wool. A layer of British fleece wool sits at the top for added warmth and comfort. Wool also handles moisture well, which helps the sleeping surface stay fresher.
- Hand-teased horsetail and Devonshire wool. Hand-teased horsetail blended with Devonshire wool creates a soft yet supportive surface. Horsetail is naturally resilient, so it keeps its spring rather than flattening the way cheaper fillings can.
- British fleece wool. A second layer of British fleece wool sits between the comfort fillings and the springs. It cushions the transition so you feel support without any sense of the springs beneath.
- Pocket springs. A two-layer, hand-nested calico pocket spring construction with 2,030 vanadium steel springs in the 150 x 200cm size. Nesting the springs by hand packs them closely together, which means more responsive, evenly distributed support across the whole mattress.

Who's it NOT for?
If you prefer a firm, unyielding surface, the medium-soft feel of this tension will likely be too gentle, though the Kingsbridge does come in firmer tensions. Anyone wanting memory foam contouring should look elsewhere, as this is a purely natural, sprung construction. And at £4,649 upwards, it is simply out of reach for many budgets.

How firm is the Vispring Kingsbridge mattress?
Vispring describes the Kingsbridge as having a medium-soft feel, so it yields gently rather than holding you on the surface. The brand's page notes it is available in multiple tensions, from Soft through to Extra Firm, so you can choose a firmer build if that suits you better.
What is the Vispring Kingsbridge made of?
Entirely natural materials: British fleece wool, hand-teased horsetail blended with Devonshire wool, and a two-layer construction of vanadium steel pocket springs hand-nested in calico pockets. There is no foam or synthetic filling, which means better breathability and a more traditional, responsive feel.
How many springs does the Vispring Kingsbridge have?
The 150 x 200cm King size contains 2,030 hand-nested vanadium steel pocket springs, arranged in two layers within calico pockets. Spring counts vary by size, so smaller mattresses will contain fewer.
How much does the Vispring Kingsbridge cost?
Prices range from £4,649 to £9,349 depending on size, with five UK sizes available from Single up to Super King. That is a significant outlay, but it reflects hand-nested calico springs and entirely natural fillings assembled by hand.
How deep is the Vispring Kingsbridge mattress?
It measures 23cm deep. That is slimmer than many modern mattresses, but the density of natural fillings and hand-nested springs means depth is a poor guide to quality here. Standard fitted sheets should fit without any trouble.
