Vispring Herald Superb Medium Mattress

Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.

If you want a mattress with no synthetic foams at all, this is the sort of build that delivers it. The wool and cotton layers regulate temperature naturally, which means hot sleepers should find it noticeably cooler than memory foam. Horsehair adds a springy, breathable quality that keeps the surface feeling fresh. The calico pocket springs are hand-nested, an old-fashioned and labour-intensive method that lets the springs move more independently than machine-made units. Yes, the price is high, but this is a mattress built to last rather than to be replaced in a few years. It suits sleepers who want a supportive, medium-firm natural feel, although anyone after a soft, cradling surface may find it too resilient.

Warm sleepers
Wool and cotton layers plus breathable horsehair regulate temperature naturally, so you should sleep noticeably cooler than you would on memory foam.

Eco-conscious buyers
The build uses no synthetic foams at all, relying on British fleece wool, cotton, horsehair and hand-nested calico pocket springs for a fully natural filling.

Back sleepers
A medium-firm feel from individually responding pocket springs gives steady, even support, which suits lying flat with your spine held in a neutral line.

Combination sleepers
The resilient, springy surface from horsehair and pocket springs makes changing position easy, rather than leaving you sinking into a slow-moving foam hollow.

Couples
Hand-nested springs flex independently in a single layer, which means each person is supported closely to their own shape across the 150 x 200cm King Size.

This is a medium-firm, naturally sprung mattress, so it will not suit anyone hoping for the sinking, contouring feel of memory foam. Lightweight sleepers who prefer a softer surface may find it a little too resilient. At a premium starting price, it is also hard to justify if you are working to a modest budget.

How firm is the Vispring Herald Superb?

Vispring describes this mattress as having a medium-firm feel. The brand's page mentions the Herald Superb is made in Soft, Medium, Firm and Extra Firm tensions, and this listing corresponds to the Medium tension. It should suit most back and combination sleepers, although lightweight side sleepers may find it slightly firm.

What is the Vispring Herald Superb made of?

The fillings are entirely natural: bonded and blended British fleece wool, cotton and horsehair, with no synthetic foams. Support comes from hand-nested vanadium steel pocket springs in calico pockets, finished with high-quality ticking, felt washers and protective wool borders.

How deep is the Vispring Herald Superb mattress?

The mattress is 21cm deep, and Vispring states there is an additional 6cm of doming on top, give or take 2cm. The doming is the natural rise created by the generous layers of wool, cotton and horsehair fillings.

How many springs does the Vispring Herald Superb have?

Vispring quotes 1,476 hand-nested vanadium steel pocket springs, arranged in a single layer, for the 150 x 200cm King Size. Spring counts vary with mattress size, so other sizes will contain a different number.

Is the Vispring Herald Superb good for hot sleepers?

It should be. The fillings are wool, cotton and horsehair, all of which breathe and wick moisture far better than synthetic foam, which means heat is less likely to build up around you overnight. If you regularly overheat on a memory foam mattress, a natural-fill design like this is a sensible switch.
