Layer Details
- Pure Belgian Damask Cover. A breathable Belgian damask fabric tops the mattress. It lets air move through the sleep surface, which helps the natural fillings below do their temperature work.
- Wool. Wool gives a soft, cushioned feel, which means gentle give at the surface before you reach the springs. It suits those who prefer a traditional, natural mattress.
- Cotton. Cotton helps regulate body temperature through the night. It also adds a degree of support alongside its natural comfort.
- eOlus™ Fibres. These fibres offer resilient body support while letting air and moisture pass through easily, so you get a soft, foam-like feel without the heat retention foam can bring. Made without harsh chemicals, the fillings are 100% recyclable with no end-of-life disposal issues.
- ReActive™ 8-Turn Pocket Springs. Each spring has 8 turns and works independently, sensing the exact comfort and support needs of you and your partner. In practice that means vertical pressure is spread smoothly, giving total spinal and body support.

- The traditional couples' footprint: At 4ft 6in x 6ft 3in, the UK double is the long-standing standard for two sharing, sized for typical British bedrooms rather than sprawling master suites.
- Independent springs where sharing matters most: With 67.5cm each for two people sharing, the ReActive 8-turn pocket springs respond to each of you separately, which matters at this width.
- Natural fillings for two warm bodies: Two sleepers generate more heat than one, and the wool, cotton and eOlus fibres let that warmth escape rather than trapping it.
- Room left for the rest of the furniture: We suggest at least 2.6m x 2.8m, which in most bedrooms still leaves space for a wardrobe and bedside tables on both sides.
- Generous for one: Sleeping solo, the full 135cm width is yours, useful if a dog or cat has quietly claimed a corner of the bed.
This size suits you if...
You share the bed every night and your room sits comfortably above our suggested 2.6m x 2.8m minimum, or you sleep alone and want space to stretch out. It also suits a guest room that hosts visiting couples, since the medium firm, natural-filled build is the kind of feel most guests get on with. If you and your partner differ in weight, the independent pocket springs help here too.
Consider another size if...
You and your partner both like to spread out, or one of you is over 6ft 3in tall. The UK king is 15cm wider and 10cm longer, and we'd recommend it if your room allows at least 2.7m x 2.9m.

Is the Hypnos Natural Luxury in a UK double big enough for a couple?
For most couples, yes. You each get 67.5cm of width, which is the arrangement British couples have shared for generations, and the ReActive 8-turn pocket springs work independently so one of you turning over disturbs the other less. If you both sleep spread out, though, it can feel snug, and the UK king would suit you better.
What room size do I need for a UK double mattress like this?
We suggest at least 2.6m x 2.8m for a UK double, and around 3m x 3m is the comfortable norm. That allows walking space on both sides and room for bedside tables. Measure with your wardrobe and drawers in mind rather than the empty floor, since those are what usually make a room feel tight.
Should I buy the Hypnos Natural Luxury in a double or a king?
The UK double fits more bedrooms and suits couples happy to sleep fairly close. The UK king is 15cm wider and 10cm longer, so it earns consideration if either of you is tall or a restless sleeper, provided your room offers at least 2.7m x 2.9m. In a smaller room, the UK double usually reads as the better-proportioned choice.
Will the double size fit up a narrow staircase?
A UK double is 135 x 190cm and, at 26cm deep, this is a substantial pocket sprung mattress, so a turning staircase in an older terrace or a tight new build landing deserves a measure before delivery day. Sprung mattresses shouldn't be folded, so check your tightest corner against the mattress dimensions and ask the retailer about access if unsure.
Is the UK double a good size if I sleep alone?
It's a genuinely comfortable solo size: 45cm wider than a UK single at the same length, so you can starfish, change position freely, or share with a pet without running out of mattress. The medium firm feel and breathable wool and cotton fillings stay consistent across that width, so wherever you drift in the night, the support is the same.
