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 natural materials and traditional craftsmanship rather than synthetic layers. The two-layer calico pocket spring unit uses springs nested by hand, which means each spring can respond independently to your body without the sagging feel that glued spring units can develop. Above that sit British fleece wool and a blend of hand-teased horsetail and Devonshire wool, fibres that breathe well and help regulate temperature, so hot sleepers should find it noticeably cooler than memory foam. Vispring describes the standard feel as gentle yet supportive, though this version is offered in Firm and Extra Firm tensions for those who prefer a more solid surface. It suits heavier sleepers and confirmed back sleepers particularly well.
Key Features & what's inside
- British fleece wool. A layer of British fleece wool sits at the surface, which means added warmth and a soft, breathable feel against the sleeping surface. Wool also wicks moisture, helping the mattress stay fresh.
- Hand-teased horsetail and Devonshire wool. Hand-teased horsetail blended with Devonshire wool gives a soft yet supportive surface. Horsetail is a traditional upholstery fibre prized for resilience, so this layer keeps its shape over time rather than compressing flat.
- British fleece wool. A second layer of British fleece wool cushions the transition between the upholstery and the springs. It adds a little extra softness and insulation above the spring unit.
- Pocket springs. A two-layer, hand-nested calico pocket spring construction with 2,030 vanadium steel springs in the 150 x 200cm size. Hand-nesting lets the springs work independently, which means support that follows your shape and less motion transfer to a partner.

Who's it NOT for?
This is a big investment, so if your budget sits below £7,449 there are capable pocket spring options elsewhere. The Firm and Extra Firm tensions may feel too solid for lightweight side sleepers, who often need more give at the shoulder and hip. It also only comes in UK King and Super King, so smaller bed frames are out.

How firm is the Vispring Kingsbridge mattress?
It depends on the tension you order. Vispring describes the standard Kingsbridge as having a medium-soft feel, gentle yet supportive, but it can be ordered in firmer tensions, and this listing covers the Firm and Extra Firm versions, which suit heavier sleepers and those who prefer a solid surface.
What is inside the Vispring Kingsbridge mattress?
Layers of British fleece wool and hand-teased horsetail blended with Devonshire wool sit over a two-layer, hand-nested calico pocket spring unit. The springs are vanadium steel, with 2,030 of them in the 150 x 200cm size, and the whole mattress is 23cm deep.
How much does the Vispring Kingsbridge cost?
Prices range from £7,449 to £9,349 depending on size. It is available in UK King and UK Super King. That is luxury pricing, though the hand-made construction and natural materials such as horsetail, Devonshire wool and calico spring pockets go some way to justifying it.
Is the Vispring Kingsbridge good for hot sleepers?
It should be. The upholstery is entirely natural fibre, wool and horsetail rather than foam, and these materials breathe and wick moisture well. If you tend to overheat on memory foam, a natural-fibre pocket spring mattress like this is usually a noticeably cooler place to sleep.
