Layer Details
- Sleep surface. A pure unbleached cotton sleep surface, free of harmful chemicals. It's a soft, breathable first point of contact.
- Comfort fillings. Generous layers of cotton and wool, including about 4kgs of traceable British Red Tractor wool, which means good temperature regulation and breathability. The cotton is naturally hypoallergenic, a helpful touch if you're sensitive to dust or synthetics.
- Resilience layer. A plush Solotex polyester fibre filling made from recycled materials, designed for durability. It promotes airflow while adding a cushioned feel between you and the springs.
- Support system. 1000 ReActivePro pocket springs, each with six active turns, so the mattress reacts faster to your movements. That translates to pressure relief and spinal alignment tailored to how you actually sleep.
- Edge support. The Triple Edge Protection system uses three rows of firmer springs around the perimeter for edge-to-edge support. Two rows of traditional hand side-stitching finish the job, a sign of proper craftsmanship.

- Real space for one: The UK small double is 30cm wider than the UK single, which means a solo adult can stretch out without touching the edges.
- Fits where a double won't: At 15cm narrower than the UK double, it can be the difference between a door that clears the bed and one that doesn't.
- Edge support matters more at 4ft: Three rows of firmer perimeter springs and hand side-stitching mean the full 120cm width is usable, with no rolling-off feeling near the sides.
- Cool for a compact room: Smaller bedrooms often run warmer, so the breathable cotton and roughly 4kgs of British wool help you avoid overheating.
- A sensible guest room choice: Two people can share for the odd weekend, and the responsive 1000-spring support system suits a bed that hosts different sleepers.
This size suits you if...
You're a solo adult who has outgrown a single and wants proper room to spread out, your bedroom, box room or loft conversion is too tight for a standard double, or you're furnishing a guest room where couples stay occasionally rather than every night. Allow at least 2.4m x 2.8m of floor space so you can still move around the bed comfortably.
Consider another size if...
You share the bed every night, because 120cm across two adults gets snug quickly. We'd recommend the UK double instead, which is 15cm wider and needs a room of at least 2.6m x 2.8m.

Is a small double Hypnos Clinton Cotton Deluxe big enough for a couple?
For occasional nights, yes, which makes it a reasonable guest room pick. As an every-night couples' bed it will feel snug, since the UK small double is 15cm narrower than the UK double. The firm perimeter springs and hand side-stitching do help, letting both sleepers use the full width right to the edge.
What room size do I need for the Hypnos Clinton Cotton Deluxe in a small double?
We suggest allowing at least 2.4m x 2.8m. The mattress itself is 120 x 190cm, and that guidance leaves enough space to open the door, walk around the bed and get to a wardrobe. In a box room or loft conversion, measure carefully before assuming a UK double would fit instead.
Is the UK small double a good size for one person?
It's arguably the best value in space per sleeper. You get 30cm more width than a UK single at the same length, so a solo adult can spread out, change position freely and keep a book or phone on the mattress without pushing anything off the edge.
Is a small double the same length as a single?
Yes. The UK small double and the UK single are both 190cm long, so the extra room is all in the width. If you're a taller sleeper wanting more length, the UK king is 10cm longer, though it's also 30cm wider and needs a room of at least 2.7m x 2.9m.
