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.

Key benefits
- Real stretching room for one: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a solo adult can change position freely without meeting the edge.
- Fits rooms a double overwhelms: It's 15cm narrower than the UK double, so a box room, loft conversion or small second bedroom keeps walking space beside the bed.
- Cool for one, workable for two: Egyptian cotton, British wool and flax breathe well, useful when the odd shared night in a guest room puts two warm bodies on a 4ft surface.
- A medium tension guests can live with: Rated medium, it suits most sleepers, which matters in a guest room where you can't tailor the mattress to whoever arrives.
- Proper depth without the footprint: The 28cm build and glue-free Cortec pocket springs give a full-sized feel underneath you, even though the mattress itself takes up less floor than a standard double.
This size suits you if...
You sleep alone and have outgrown a single, perhaps a teenager's room that can't give up any more floor space, or your bedroom simply won't take a 4ft 6in frame without blocking the door. It also fits if you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, and you want natural fillings rather than a budget foam roll-up.
Consider another size if...
You share the bed every night and want it to stay comfortable long term. The UK double is 15cm wider and we'd recommend it instead, provided your room offers at least 2.6m x 2.8m.

FAQ's
How big is the Harrison Spinks Durham 6950 in a UK small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in. The length is the same as a UK single and a UK double; the difference is all in the width. Depth is 28cm across every size, so you get the full layered build in this smaller footprint.
Will the small double Durham 6950 fit in a box room?
Usually, yes, and that's largely the point of the size. We suggest a room of at least 2.4m x 2.8m so you can still open the door and walk around the bed. Measure the room with furniture in place before you decide, especially in loft conversions where sloping ceilings eat into usable space.
Is the Durham 6950 small double big enough for a couple?
For occasional nights, such as guests staying over, two people manage fine, helped by the breathable wool and cotton fillings. As an every-night bed for two, 120cm is tight. The UK double gives you 15cm more width for the same length, which makes a noticeable difference over years of shared sleep.
How much bigger is the small double than a single for this mattress?
The UK small double is 30cm wider than the UK single, and both are the same 190cm length. That extra width is what turns a functional bed into one you can properly spread out on, without stepping up to a footprint your room can't take.
Is a UK small double worth it for one person on a mattress like this?
If you sleep alone and value the extra width, yes. The medium tension and pocket sprung support don't change with size, so you're getting the same feel as the larger sizes in a shape that suits a compact room. Compare the retailers listed on this page for current pricing.
