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.

- 90cm of latex each: Two people sharing get 90cm each, which means a partner who turns all night becomes far easier to sleep beside.
- Room for the whole household: When children wander in during the small hours, or the dog treats the bed as home, the 180cm width means nobody ends up perched on an edge.
- Responsive latex across the full width: Talalay latex springs back rather than holding a body-shaped dip, which means shifting position on your side of a big bed feels easy, never sunken.
- Fills a large master properly: In a period property or generous new build master, a UK king can look undersized; the super king suits the room's scale.
- Cool surface at any scale: The cooling sleep surface and aerated core matter more when two adults, and sometimes more, share one mattress every night.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and distance matters more to you than any comfort layer, or children and pets regularly join you and everyone still needs their share. Your bedroom should measure at least 3m x 2.9m, and nearer 3.5m x 3.2m to feel comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king. We'd recommend the UK king instead: it's 30cm narrower but the same length, and needs at least 2.7m x 2.9m.

What room size do I need for the Dunlopillo Sovereign in a UK super king?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling right. That's our own guidance rather than Dunlopillo's, and it allows for walking space on both sides plus bedside tables. Check door swing and wardrobe access too, as those bite at this size.
How much bigger is the super king Dunlopillo Sovereign than the king?
The UK super king is 30cm wider than the UK king, and both are the same length at 200cm. All that extra width goes into the space between you and your partner, which is exactly where restless-sleeper problems live. If your room can hold it, the difference is noticeable every night.
Is the Dunlopillo Sovereign super king good for couples with children who climb in?
It's the best-suited size for it. At 180cm wide, a third small body in the middle still leaves two adults with usable space, where a UK double would feel crowded. The latex surface is responsive rather than slow-moving, so nobody sinks into a hollow when the bed gets busy.
How much space does each person get on a super king Dunlopillo Sovereign?
Two people sharing get 90cm each. That's a generous personal zone, and because Talalay latex responds quickly rather than cradling you in one spot, moving around your own side is easy. If one of you is a light sleeper, that width does more than any comfort layer could.
Will the super king be too big for my bedroom?
Measure before you buy. The mattress is 180 x 200cm, or 6ft x 6ft 6in, and we'd want a room of at least 3m x 2.9m around it. If that's tight, the UK king is 30cm narrower and the same length, and we suggest at least 2.7m x 2.9m for that size.
