Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this if you want deep natural upholstery and a spring system built to last decades rather than years. The two-layer construction uses 2,520 springs in the 150 x 200cm size, giving fine-grained support that adapts to your shape. Horsetail is a rare filling for a reason: it is springy, breathable and hand-teased, which means it recovers its loft night after night instead of compacting. The border is reinforced with coir and wool and finished with four rows of hand side-stitching, so the edges stay supportive over time. If you sleep hot, the wool, silk and mohair blend handles moisture and temperature far better than synthetic foams tend to.
Key Features & what's inside
- Upholstery - Top Layer. British fleece wool sits alongside hand-teased horsetail blended with real Shetland wool, silk and mohair, plus a blend of Shetland wool and cotton, all encased in high-quality ticking. In practice this means a breathable, cushioned surface that regulates temperature well and keeps its shape.
- Springs. A two-layer hand-nested calico pocket spring construction made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Each spring works independently, so you feel support tailored to your shape and less disturbance from a partner's movement.
- Borders. The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. That stitching anchors the fillings to the springs at the edge, which means firmer edge support and a mattress that holds its shape for longer.

Who's it NOT for?
This is a poor fit if your budget has a ceiling anywhere near normal mattress prices: from £8,649, it costs more than most people spend on a bed in a lifetime. It also uses animal-derived fillings throughout, so it is unsuitable for vegans. And if you prefer the contouring hug of memory foam, a traditional sprung feel may disappoint.

How many springs does the Vispring Sublime Superb have?
It uses a two-layer hand-nested calico pocket spring construction with 2,520 springs, a figure Vispring specifies for the 150 x 200cm size. Smaller or larger sizes will have a different count. The springs are made from vanadium steel and pocketed individually so they respond to your body independently.
What is the Vispring Sublime Superb made of?
The upholstery combines British fleece wool, hand-teased horsetail blended with Shetland wool, silk and mohair, and a Shetland wool and cotton blend. Underneath sit calico pocket springs made from vanadium steel, with coir and wool protecting the borders. Every filling is natural, which helps with breathability and temperature regulation.
How deep is the Vispring Sublime Superb mattress?
Vispring states the depth as 23cm, plus around 6cm of doming (give or take 2cm). The doming is the gentle rise in the middle created by the generous natural fillings, and it settles slightly with use, so expect the surface to soften a little over the first months.
What firmness is the Vispring Sublime Superb available in?
Vispring offers it in four tensions: Soft, Medium, Firm and Extra Firm. This is the Medium tension, which suits most sleepers, although heavier builds may prefer Firm and lightweight side sleepers might lean towards Soft. Being able to choose your tension is one advantage of a handmade mattress.
How much does the Vispring Sublime Superb cost?
Prices range from £8,649 to £12,049 depending on size, with UK Single and UK Double listed. That is undeniably a lot, but you are paying for hand-nesting, hand side-stitching and rare natural fillings like horsetail, rather than a marketing premium on a machine-made product.
