Layer Details
- Dunlopillo® Plus Sleep Surface. A cooling fabric that stays around 1°C below your body temperature, which means the surface feels fresher when you first get in. If you're a hot sleeper, this is the layer working hardest for you.
- Natural Talalay Latex. A deep core layer of 100% natural Talalay latex, which means bounce and breathability rather than a sinking feel. It's the material that gives this mattress its responsive, easy-to-move-on character.
- VENTRA™ Core Performance System. Sitting beneath the latex, this system actively channels air through the entire mattress. In practice that means heat and moisture have somewhere to go overnight.

- Proper space for two: At 75cm each for two people sharing, you can both change position without negotiating, which matters on a responsive latex surface that's easy to move on.
- Kinder to different schedules: If one of you gets up hours before the other, the wider surface means an early exit happens further from your partner's side of the bed.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, so feet stay on the mattress rather than hanging off the end.
- Breathable across the whole width: The aerated latex core channels air through the full 150cm surface, so neither sleeper ends up on a warm patch the other has left behind.
- Room for a bed-sharing dog: If a dog claims the foot of the bed most nights, the extra width over a UK double stops that costing one of you a comfortable position.
This size suits you if...
You share the bed every night and a UK double has started to feel like a compromise, one of you is approaching six foot and wants that extra 10cm of length, or your sleep schedules rarely match and you'd rather an early alarm didn't wake you both. Latex is easy to shift position on, and the wider surface gives that movement somewhere to go.
Consider another size if...
Your bedroom is under the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. The UK double would suit a smaller room, with at least 2.6m x 2.8m needed, and a UK single works well for one.

Is the Dunlopillo Millennium in a UK king long enough for tall sleepers?
At 200cm, the UK king gives you 10cm more length than the UK double, which is a genuine relief if either of you is close to six foot. Anyone taller than that should still lie with a little clearance, since 200cm is the maximum length Dunlopillo offers for this mattress across its standard UK sizes.
What room size do I need for the Dunlopillo Millennium UK king?
We suggest a room of at least 2.7m x 2.9m for a UK king, and that's our guidance rather than Dunlopillo's. In a new build master bedroom, measure after accounting for wardrobes and door swing, as these rooms often feel smaller once furniture is in. If you're tight, the UK double needs at least 2.6m x 2.8m.
Is a UK king Millennium good for couples on different schedules?
It helps. Latex is springier than memory foam, so movement is felt more readily than on a slow-response foam, but the 150cm width puts real distance between you. When one of you leaves for an early shift, they can slide out from their own side without crossing yours, which is where most of the disturbance usually comes from.
Should I choose the Millennium in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king, and both are the same 200cm length. If you have the space, the UK super king gives each of you noticeably more width, but it needs a room of at least 3m x 2.9m. For most couples the UK king is the sensible middle ground.
How much space does each person get on a UK king Millennium?
Two people sharing get 75cm each, which is more personal territory than a UK double offers, as the UK king is 15cm wider. On a bouncy Talalay latex mattress that extra margin is useful, because a responsive surface encourages moving around and the added width means that movement stays on your own side.
