Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the Dartington if natural materials matter to you. Wool and cotton breathe far better than foam, which means less heat building up around you overnight. If you're a hot sleeper, that alone may justify the price gap over synthetic alternatives. The hand-nested calico pocket springs respond to each sleeper independently, so a restless partner is less likely to disturb you. The gently cushioned medium tension suits most sleepers, although anyone who prefers a firmer feel should know Vispring offers this model in other tensions too. At 21cm deep plus around 6cm of doming, it has a traditional, slightly plump profile rather than the deep, boxy shape of many modern mattresses.
Key Features & what's inside
- Upholstery. Bonded and blended British fleece wool with cotton, encased in high-quality ticking, which means a breathable, temperature-regulating sleep surface with no synthetic foam. It is hand-tufted with felt washers, so the fillings stay anchored rather than migrating and lumping over time.
- Springs. A single layer of 1,558 hand-nested vanadium steel pocket springs in calico pockets, based on the king size. Each spring moves independently, which means the mattress contours to your shape and limits motion transfer between partners.

Who's it NOT for?
This is a poor fit for anyone on a tight budget, as prices start at £3,099. Sleepers who love the sink-in hug of memory foam may find the springy, cushioned feel unfamiliar. And if you need a very firm surface, this medium tension will feel a little too yielding, though firmer tensions of the Dartington exist.

Is the Vispring Dartington a firm mattress?
No. This is the medium tension, which Vispring describes as a gently cushioned feel. The Dartington is made in four tensions, Soft, Medium, Firm and Extra Firm, so a firmer version exists if you need more resistance under your back.
What is the Vispring Dartington made of?
Entirely natural fillings: bonded and blended British fleece wool with cotton, hand-tufted with felt washers. Support comes from hand-nested vanadium steel pocket springs in calico pockets. There is no memory foam or synthetic filling in the build.
How many springs does the Vispring Dartington have?
It has 1,558 hand-nested pocket springs in a single layer, made from vanadium steel. That figure is specified for the king size (150 x 200cm), so smaller sizes will contain proportionally fewer springs.
How deep is the Vispring Dartington mattress?
The stated height is 21cm, plus around 6cm of doming (give or take 2cm) from the generous natural fillings. That makes it shallower than many modern mattresses, which some buyers prefer for fitted sheets and traditional bedsteads.
What sizes does the Vispring Dartington come in?
It is available in UK Single, Small Double, Double, King and Super King. Prices range from £3,099 to £6,399 depending on the size you choose.
