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.

- 75cm each for two sharing: That's 75cm each for two people sharing, so an early riser can slip out at six without dragging the duvet off their partner.
- Pocket springs limit disturbance: The glue-free Cortec pocket springs respond individually, which means one person turning over transfers less movement across a 150cm-wide surface.
- 200cm of length for taller sleepers: The UK king is 10cm longer than the UK double, and on a 28cm-deep mattress that extra length stops feet hanging over the edge.
- Natural fillings across a bigger surface: Egyptian cotton, British wool and flax breathe well, useful when two bodies share one mattress and the warm side is a real thing.
- Arrives flat, so measure access: This mattress is delivered flat rather than rolled, and at 150 x 200cm it needs a clear route up stairs and around landings.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, or one of you keeps different hours and you want movement on one side to stay on that side. It also suits couples where the taller partner needs the 200cm length, and anyone whose dog has claimed a corner of the bed as a permanent arrangement.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead, which needs a room of at least 2.6m x 2.8m and still gives a solo sleeper generous space.

Is the Harrison Spinks Durham 6950 UK king good for couples?
Yes, and it's arguably the size this mattress makes most sense in. You get 75cm each for two people sharing, and the glue-free Cortec pocket springs move independently, so one partner shifting position sends less motion across the bed. If you're regularly woken by a restless sleeper, the step up from a UK double is one you'll feel.
What room size do I need for the Durham 6950 in a UK king?
We suggest at least 2.7m x 2.9m, with something closer to 3.2m x 3.2m feeling genuinely comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure the floor with furniture in place rather than trusting the floor plan.
Is the UK king Durham 6950 long enough for tall sleepers?
At 200cm long, the UK king is 10cm longer than the UK double, which matters more than the width if one of you is approaching six foot. Anyone taller than that should still lie diagonally in a showroom before committing, but for most tall sleepers the length here is the real upgrade.
Will the Durham 6950 king size fit up my stairs?
This is the question to answer before you order. The Durham 6950 arrives flat rather than rolled, which is gentler on the natural fillings but means a rigid 150 x 200cm mattress has to make every turn on the way up. Measure narrow staircases, low ceilings and tight landings first.
Should I choose the Durham 6950 in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king and the two are the same length, so the decision is about width and room size. For the UK super king we suggest a room of at least 3m x 2.9m. If your bedroom clears that and you both sprawl, size up; otherwise the UK king is the sensible pick.
