Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this mattress if you want natural materials and a genuinely soft, cushioned feel without giving up support. The two-layer pocket spring construction, 2,520 springs in the 150 x 200cm King size, means the springs respond to your body independently, so you sink in where you are heavier and stay supported everywhere else. Horsetail and wool fillings breathe far better than synthetic foams, which matters if you sleep warm. The four rows of hand side-stitching keep the edges firm, so you can sleep right up to the border. Yes, the price is high, but the materials and hand construction are the reason, and the range of tensions lets most sleepers find a fit.
Key Features & what's inside
- Upholstery. Every filling is natural: British fleece wool, hand-teased horsetail blended with real Shetland wool, silk and mohair, plus blended Shetland wool and cotton, all encased in high-quality ticking. In practice that means a breathable, temperature-regulating surface that softens with body shape rather than trapping heat the way foam can.
- Springs. Two layers of hand-nested calico pocket springs made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Nesting the springs by hand in calico pockets lets each one move independently, which you feel as support that follows your shape closely.
- Borders. The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. This stiffens the edges, so the mattress holds its shape over time and supports you when you sit or sleep near the side.

Who's it NOT for?
If your budget is anywhere near typical mattress spending, this is not the one: it starts at £8,649. In the Soft tension it will feel too yielding for heavier sleepers or dedicated stomach sleepers, who would be better served by one of the firmer tensions. Anyone avoiding animal-derived materials should also look elsewhere.

Is the Vispring Sublime Superb only available in soft?
No. Vispring's own page lists four tensions for this model: Soft, Medium, Firm and Extra Firm. The Soft version suits lighter sleepers and side sleepers who want plenty of surface cushioning, while heavier sleepers can pick a firmer tension of the same construction.
How many springs does the Vispring Sublime Superb have?
Vispring states 2,520 springs for the 150 x 200cm size, which is the 5ft x 6ft 6in King. Other sizes will differ, since spring counts scale with mattress area. The springs are hand-nested in calico pockets and made from vanadium steel, arranged in two layers.
How deep is the Vispring Sublime Superb mattress?
Vispring states a depth of 23cm, plus around 6cm of doming on top, give or take 2cm. Doming is the gentle rise created by the natural fillings, so the mattress sits taller in the middle than the border measurement suggests.
What is the Vispring Sublime Superb made of?
The fillings are entirely natural: British fleece wool, hand-teased horsetail blended with Shetland wool, silk and mohair, plus Shetland wool and cotton. The borders use coir and wool with four rows of hand side-stitching. The springs are vanadium steel in hand-nested calico pockets.
How much does the Vispring Sublime Superb cost?
Prices range from £8,649 to £17,599 depending on size, with UK Single, Double, King and Super King available. It sits firmly at the luxury end of the market, and the cost reflects the all-natural fillings and hand-built pocket spring construction.
