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.

- Fits where space is tight: At 90cm wide it leaves floor room for a desk, wardrobe or toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Natural fillings for a child or teen: The unbleached cotton sleep surface is naturally hypoallergenic, which means it's a gentler choice for younger sleepers sensitive to dust or synthetics.
- A guest bed worth offering: The 1000 six-turn pocket springs and wool fillings give visitors a proper night's sleep, a step up from the thin mattresses spare rooms often get.
- Edge support in a narrow bed: Three rows of firmer perimeter springs and hand side-stitching matter more at 3ft wide, where you sleep closer to the edge by default.
- Cool for warm sleepers: Cotton and around 4kgs of British wool breathe and wick moisture, so a solo sleeper in a small, warm room is less likely to overheat.
This size suits you if...
You're a solo adult sleeper who wants natural materials and a traditional pocket spring feel in the standard one-person size, you're furnishing a child's or teenager's room and want a mattress built to last through those years, or you're upgrading a guest room and would rather visitors slept on something you'd happily use yourself.
Consider another size if...
You share the bed, or you're a solo sleeper who sprawls and finds 90cm restrictive. We'd recommend the UK double instead: it's 45cm wider than the UK single, the same length, and we suggest a room of at least 2.6m x 2.8m for it.

Is the Hypnos Clinton Cotton Deluxe UK single a good choice for a child's bedroom?
It's a considered one. The unbleached cotton surface is naturally hypoallergenic and free of harmful chemicals, and the wool fillings help regulate temperature, both useful for younger sleepers. The medium tension suits growing bodies without being too firm. It costs more than a basic children's mattress, but it's built to last through the teenage years.
Will the UK single Hypnos Clinton Cotton Deluxe fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. The thing to check is depth: at 26cm this is deeper than many mattresses sold for raised frames, and a top bunk needs the guard rail to sit well above the mattress surface. Measure your frame's maximum mattress depth before buying.
What size room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk alongside the bed and open drawers or wardrobe doors. That makes the UK single a realistic fit for box rooms, loft conversions with a narrow usable footprint, and spare rooms that double as an office.
Is the UK single Hypnos Clinton Cotton Deluxe long enough for a tall adult?
At 190cm (6ft 3in) long, it works for most adults, but taller sleepers may find their feet near the end. The UK king is 10cm longer than the UK single as well as 60cm wider, so if length is the concern and your room allows at least 2.7m x 2.9m, that's the size to consider.
Should I size up from the UK single to the UK small double?
If you're a solo adult who feels hemmed in at 3ft wide, yes. The UK single is 30cm narrower than the UK small double, and the two are the same length, so you gain sprawling room without needing a longer bed. We suggest at least 2.4m x 2.8m of floor space for the UK small double.
