Layer Details
- Dunlopillo® Plus Sleep Surface. A cooling fabric designed to stay around 1°C below your body temperature. In practice, that means the surface feels fresh when you get in rather than warming up quickly.
- Natural Talalay Latex. A deep layer of natural Talalay latex that gently contours to your body. You'll feel adaptive comfort and pressure relief without sinking in the way you would on memory foam.
- VENTRA™ Core Performance System. An aerated foam core engineered to boost airflow and breathability. It helps the mattress stay cool year round rather than trapping heat beneath you.

- Fits a typical UK bedroom: At 135 x 190cm the UK double leaves room for wardrobes and drawers where the UK king, 15cm wider and 10cm longer, might not.
- Easy movement in shared space: With 67.5cm each, Talalay latex's responsive feel means you can turn over without disturbing your partner or fighting the mattress.
- Cooler for two: Two bodies raise the temperature under the duvet, so the cooling sleep surface and aerated VENTRA core matter more in a shared size.
- Bedding is cheap and everywhere: Double sheets and duvets are stocked at every price point, which helps if you're furnishing a whole home at once.
- Room for bedside tables: In a room of at least 2.6m x 2.8m, our suggested minimum, a UK double usually still allows a table on each side.
This size suits you if...
You share the bed every night and your room sits comfortably around our suggested 2.6m x 2.8m minimum, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, where latex's long lifespan means the mattress will still feel right years between uses.
Consider another size if...
You and your partner both like space, and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer, which you'll notice every night.

Is the Dunlopillo Sovereign UK double big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, and because Talalay latex responds quickly rather than holding a dent, moving around in that width feels easier than it would on slower foam. Larger sleepers, or couples who like to sprawl, may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Dunlopillo Sovereign in a UK double?
We suggest at least 2.6m x 2.8m. That allows walking space around the bed and, in most layouts, a bedside table on each side. If your room is a good deal bigger, at least 2.7m x 2.9m, it's worth weighing up the UK king before you commit, since the extra width is hard to add later.
Will a UK double latex mattress get up narrow stairs?
Latex is flexible, so the Sovereign will bend around a turning staircase in an older terrace or a tight new build landing more forgivingly than a rigid sprung mattress. At 135cm wide it's still a two-person carry. Measure your tightest corner before delivery day, and check the retailer's delivery terms for access requirements.
Is a double Dunlopillo Sovereign a good choice for a guest room?
It's a strong fit. The UK double footprint suits the smaller rooms guest beds usually occupy, it sleeps visiting couples comfortably, and latex holds its shape through long gaps between uses. The hypoallergenic construction is a quiet bonus when you don't know which guests have allergies. It's a serious spend for a bed used occasionally.
Should a solo sleeper buy the Sovereign in a UK double or a UK single?
If the room allows it, the UK double. It's 45cm wider than the UK single at the same length, which is the difference between sleeping in one position and genuinely spreading out, especially if a pet shares the bed. The UK single, needing a room of at least 2.1m x 2.8m, suits tighter spaces like a first flat or box room.
