Layer Details
- Belgian damask cover. A breathable Belgian damask fabric tops the mattress. It lets air move through the sleep surface rather than sealing heat in.
- Wool layer. Wool fillings give a soft, cushioned feel at the surface, which means the firm springs beneath don't feel harsh against your body. It's a natural choice if you prefer a traditional mattress over synthetic foams.
- eOlus fibres. These fibres offer resilient body support while letting air and moisture pass through easily. Unlike foam, they don't hold onto heat or sweat, yet they still give a soft, foam-like feel.
- ReActive 7-turn pocket springs. Each spring has seven turns and works independently, sensing the comfort and support needs of you and your partner and spreading downward pressure smoothly. In practice, that means full spinal support and less disturbance when one of you moves.

- Room for two without crowding the bedroom: At 135cm wide, the UK double leaves space for wardrobes, drawers and walking room where a UK king would start to dominate.
- Independent support across a shared bed: The ReActive 7-turn pocket springs respond to each sleeper separately, which means at 67.5cm each for two people sharing, you feel your own support rather than your partner's movements.
- Fits bedside tables on both sides: In a room around our suggested 2.6m x 2.8m minimum, the UK double usually still allows a bedside table each, which sharers tend to miss more than mattress width.
- Cool sharing thanks to wool and eOlus fibres: Two bodies raise the temperature under one duvet, so the breathable wool and eOlus layers matter more in a shared UK double than in a solo size.
- A safe choice for a guest room: Visiting couples fit comfortably, and the firm feel suits back and front sleepers, which covers most guests you can't tailor a mattress to.
This size suits you if...
You share the bed every night and your room sits close to our suggested 2.6m x 2.8m minimum, so a UK king would feel cramped around the edges. Or you're furnishing a guest room that needs to sleep visiting couples comfortably. Solo sleepers who like space to stretch out, or who share with a dog claiming a corner, will find the extra width over a UK single genuinely useful.
Consider another size if...
You and a partner both toss and turn, or one of you is broad shouldered, and 67.5cm each feels tight. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m of room and we'd recommend it instead.

Is the Hypnos Wool Ortho UK double wide enough for a couple?
It gives two sharers 67.5cm each, which most couples find comfortable, and the pocket springs keep one person's movement from disturbing the other. If either of you is tall, note the UK double is 10cm shorter than the UK king as well as 15cm narrower, so taller couples may prefer sizing up.
What room size do I need for the Hypnos Wool Ortho double?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides and space to open a wardrobe. If your room clears 2.7m x 2.9m, a UK king becomes an option too.
Should I get the Hypnos Wool Ortho in a double or a king?
Choose the UK double if your bedroom is on the smaller side or you want the widest choice of affordable bedding. The UK king adds 15cm of width and 10cm of length, and needs a room of at least 2.7m x 2.9m. Sharers who value elbow room usually prefer the UK king when the room allows.
Will a double mattress fit up the stairs in an older house?
Pocket sprung mattresses like this one flex a little but shouldn't be folded, and at 135 x 190cm the UK double is manageable on most staircases, though tight turns in older terraces can be awkward. Measure your narrowest landing before ordering, and check the retailer's delivery guidance for access requirements.
What bedding do I need for this mattress in a double?
Standard UK double sheets fit the 135 x 190cm footprint, and a 200 x 200cm double duvet is the usual pairing. The mattress is 26cm deep, so most standard fitted sheets will cover it, though it's slightly deeper than some budget sheets allow for. Double bedding is stocked everywhere, at every price point.
