Dorma Natural 2000 Pocket Sprung Wool Mattress reviewed

The Dorma Natural 2000 Pocket Sprung Wool Mattress is a 27cm, hand-tufted, dual-sided mattress built around 2,000 pocket springs with British wool and cotton on both faces, sold only at Dunelm from £409 for a single to £709 for a super king at the time of writing (September 2026). Dunelm gives it a 20-year guarantee and sells it in soft, medium or firm tension at the same price.

Construction

The layer order comes from the diagram on the Dunelm product page, which repeats the same fillings on the underside so the mattress can be flipped. There is no foam. Wool is there for moisture handling rather than softness: British Wool states that wool can absorb up to 30% of its own weight in moisture without feeling wet, and releases it again as the air around it dries.

Sizes, weights and prices

Regular Dunelm prices, checked on 28 September 2026; soft, medium and firm cost the same, although the soft tension was out of stock in every size on that date. Weights are Dunelm’s packaging figures.

Feel, upkeep and who it suits

Our rating assumes the medium tension, which we score 5 out of 10. Dunelm lists it for back sleepers. We would steer heavier and front sleepers to the firm tension and lighter side sleepers to the soft one, once it is back in stock. The trade-off for natural fillings is maintenance. Dunelm asks you to rotate and turn it every two weeks for the first three months, then every three months, and integrated side handles make that manageable, though a 32kg double is still a two-person job.

The 20-year guarantee also appears on Dunelm’s mattress guarantee list, where Dorma has the longest mattress term on the list, ahead of 15 years for Hotel and 10 for Fogarty. That is well beyond how long most people keep a mattress: in a National Bed Federation survey of recent bed buyers, 41% had replaced their old mattress within five years or less. The catch is the lack of a sleep trial. Dunelm’s returns policy says mattresses cannot be returned once unwrapped unless faulty, so try the tension in a Dunelm store if you can.
