Choose the Millennium if you sleep hot or you're tired of foam that hugs you too closely. Talalay latex is naturally breathable, and here it's paired with a cooling sleep surface designed to sit around 1°C below your body temperature and an aerated core that channels air through the whole mattress. The medium feel gives a balanced middle ground for back and side sleepers. It also carries a Fire Resistant Low Hazard certification (BS7177: 2008) and is 100% free from animal by-products. Yes, the from-price of £1,239 is steep, but a 15-year guarantee listed by the retailer gives the outlay some reassurance.
Key Features & what's inside
- 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.

Who's it NOT for?
Skip this one if you're on a tight budget, as it starts at £1,239, or if you prefer the slow, cradling hug of memory foam, since latex feels bouncier. The medium feel may also be too soft for heavier sleepers who need firm support, and at 24.5cm it sits deeper than some older Dunlopillo models.

Is the Dunlopillo Millennium mattress firm or soft?
It's rated medium, a balanced feel that suits most back and side sleepers. Lighter sleepers should find enough give for their shoulders and hips, although those who want a distinctly firm surface may find it a little too yielding.
What is the Dunlopillo Millennium made of?
It's built around a deep layer of 100% natural Talalay latex, topped with the Dunlopillo Plus Sleep Surface cooling fabric and supported by the VENTRA Core Performance System, an aerated foam core. It's hypoallergenic, vegan friendly and made in the UK.
Does the Dunlopillo Millennium come with a guarantee?
The MattressNextDay listing states a 15-year guarantee, which is longer than most brands offer. Do confirm the guarantee terms with whichever retailer you buy from, as they can vary between sellers.
How deep is the Dunlopillo Millennium mattress?
It's 24.5cm deep. One owner mentioned this is deeper than their previous Dunlopillo mattress and made getting into bed slightly harder for shorter people, so it's worth checking against your bed frame height.
What sizes does the Dunlopillo Millennium come in?
It's available in UK Single, UK Double, UK King, UK Super King and EU Single, with prices ranging from £1,239 to £2,269 depending on the size you choose.
