Choose the Durham 6950 if you value natural materials and spring-based support over foam. The two layers of micro springs contour to your body much like foam does, which means pressure relief at the shoulders and hips without memory foam's warmth or slow response. The wool and flax fillings regulate temperature, so if you're a hot sleeper this construction works in your favour. The British wool is traceable to Harrison Spinks' own Yorkshire farm, a nice reassurance if provenance matters to you. Yes, the from-price of £929 is more than many rolled mattresses, but you're getting a 28cm-deep, glue-free build backed by a Harrison Spinks 10 year guarantee, as listed by MattressNextDay.
Key Features & what's inside
- Cover. A breathable Belgian damask cover, woven without FR chemicals. That means fire safety is achieved through the fabric itself rather than chemical treatments.
- Egyptian Cotton. A generous layer of super fine Egyptian cotton strands gives a soft, plush sleep surface. It also wicks moisture, which means you stay cool and dry through the night.
- British Wool and Flax Blend. A blend of British wool and flax that breathes well and helps regulate temperature. The wool is traceable, collected from Harrison Spinks' own Yorkshire farm.
- Viscose Wool. Viscose wool derived from the wood pulp of eucalyptus, beech and pine trees. It adds another breathable, temperature-regulating layer to the fillings.
- Micro Springs. Two layers of in-house designed micro springs that contour to your body much like foam. They offer support and relief that adapt to your individual shape.
- Cortec™ Pocket Springs. Glue-free Cortec pocket springs that support your pressure points and adapt to changes in your weight as you move. In practice, that means consistent pressure relief whichever position you settle into.

Who's it NOT for?
If you prefer a distinctly firm or distinctly soft mattress, this medium tension won't suit. It arrives flat rather than rolled, so anyone with narrow stairs or tight corners should measure carefully. And if you're on a tighter budget, the £929 starting price puts it beyond many rolled hybrid alternatives.
Harrison Spinks Durham 6950 Mattress

How firm is the Harrison Spinks Durham 6950?
It's a medium tension, which suits most back and side sleepers who want a balance of cushioning and support. It won't suit anyone set on a firm orthopaedic feel or a very soft, sink-in surface.
How many springs does the Durham 6950 have?
It has 6,950 springs in total, combining two layers of micro springs with glue-free Cortec pocket springs. The micro springs contour like foam, while the pocket springs handle deeper support and adapt as you move.
Does the Harrison Spinks Durham 6950 come rolled in a box?
No, it arrives flat rather than rolled and boxed. That's kinder to the natural fillings and springs, but it does mean you should check doorways, stairs and landings before ordering.
What guarantee does the Durham 6950 come with?
The MattressNextDay listing states a Harrison Spinks 10 year guarantee. No trial period is stated on that listing, so check terms with your chosen retailer before you buy.
What sizes is the Harrison Spinks Durham 6950 available in?
It comes in a wide range: UK Small Single, Long Small Single, Single, Small Double, Double, King and Super King, plus EU Single, Double and King. Prices run from £929 to £1,799 depending on size.
