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.

- A shared size for typical rooms: At 135 x 190cm, the UK double fits comfortably in bedrooms where a UK king would leave little space to walk around.
- Edge support matters more when sharing: Three rows of firmer perimeter springs and hand side-stitching mean neither of you feels perched when you drift towards the edge.
- Springs that respond to two sleepers: The 1000 ReActivePro pocket springs each move independently, which means your partner's turning is less likely to travel across the bed to you.
- Natural fillings for two warm bodies: Cotton and wool breathe well, useful when two people share 135cm of mattress and the heat builds faster than it would sleeping alone.
- Easy to dress and easy to buy: Double bedding is stocked everywhere at every price, and nearly every UK bed frame comes in this size.
This size suits you if...
You share the bed every night and your room sits around the typical UK bedroom size, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since 67.5cm each for two people sharing is workable for occasional stays. Allow at least 2.6m x 2.8m of floor space.
Consider another size if...
You and your partner both like room to sprawl, or one of you is broad-shouldered. The UK king is 15cm wider and 10cm longer; we'd recommend it if your room allows at least 2.7m x 2.9m.

Is a UK double Hypnos Clinton Cotton Deluxe big enough for a couple?
For most couples, yes. Two people sharing get 67.5cm each, which is workable, though a restless sleeper will notice the limit. The six-turn pocket springs help here, absorbing movement so you feel less of your partner's shifting. If you both spread out, the UK king is 15cm wider and 10cm longer.
Will a UK double fit my bedroom with bedside tables on both sides?
We suggest at least 2.6m x 2.8m for a UK double, and that allows a slim table each side with room to walk around the bed. In a room nearer 3m x 3m you'll have comfortable clearance. Measure the wall the bed sits against before deciding, including any radiators or built-in wardrobes.
Should I get the Hypnos Clinton Cotton Deluxe in a double or a king?
It comes down to your room and how you sleep. The UK double suits rooms around the 2.6m x 2.8m minimum we suggest; the UK king needs at least 2.7m x 2.9m and gives you 15cm more width and 10cm more length. Couples who wake each other tend to appreciate the extra width.
How heavy is the UK double to get upstairs?
Hypnos doesn't publish a weight for this size, but a traditional pocket spring mattress with around 4kgs of wool plus cotton fillings is a two-person lift. It doesn't arrive rolled, so measure turning stairs in older terraces and tight new build landings before ordering, and check the retailer's delivery access guidance.
Is a double a good choice for a guest room?
A strong one. The UK double handles visiting couples, and the edge support means guests of different sizes can each use their full half without feeling tipped off the side. This is a considered spend for occasional use, but the natural fillings and 10-year guarantee suit a bed you want to last.
