The Harrison Spinks Durham 6950 is rated medium, a tension that suits most sleepers, although anyone wanting a firm orthopaedic feel should look elsewhere. Natural fillings including Egyptian cotton, British wool and flax help it breathe, so hot sleepers are well served. It's a serious spend, but the 28cm depth, glue-free Cortec springs and NBF-approved manufacturing help explain the price. It arrives flat rather than rolled, which is gentler on the materials inside.

Why should you choose this mattress?
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 starting price 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 & layer details
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.

Eco-conscious buyers

Allergy sufferers
The Belgian damask cover is woven without FR chemicals, so fire safety comes from the fabric itself rather than chemical treatments.
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 starting price puts it beyond many rolled hybrid alternatives.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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.
