Layer Details
ActiGel foam
Zoned ActiGel foam that TheraPur says controls heat better than traditional memory foam. It eases pressure while keeping you cooler than a standard memory foam would.
PurFibre comfort layer
A resilient PurFibre layer that adds gentle cushioning. It softens the feel a little without taking away the supportive medium-firm rating.
Platinum 3D comfort layer
A breathable layer that enhances airflow and responsiveness. You get less trapped heat and a mattress that reacts quickly when you move.
ActiCool+ cover
A graphite-infused knitted cover, described as TheraPur's coolest ever feel. It gives you a cool-feeling surface when you first lie down.

Key benefits
- Leaves room around the bed: Compared with the UK king, the UK double is 15cm narrower and 10cm shorter, so a typical bedroom is more likely to fit bedside tables on both sides.
- Calmer nights at close quarters: With 67.5cm each, you sleep fairly close together, and the separately wrapped pocket springs mean a partner's movement is less likely to travel across to you.
- Helps when two people run warm: Two bodies in a UK double build up heat, so couples who overheat may welcome the graphite-infused cover and breathable Platinum 3D layer.
- Bedding is easy to find: Standard double sheets and a 200 x 200cm double duvet fit, which means you can buy bedding almost anywhere rather than hunting for specialist sizes.
- A sensible guest room choice: In a spare room, a medium firm UK double gives visiting couples a supportive shared bed while leaving space for a wardrobe or chest of drawers.
This size suits you if...
You share the bed with a partner in an average-sized bedroom and still want space for bedside tables, or you're furnishing a guest room where visiting couples need a supportive, cool-feeling bed without it filling the room.
Consider another size if...
You and your partner like plenty of personal space and your room is at least 2.7m x 2.9m. We'd recommend the UK king instead, which gives 75cm each for two sharing.

FAQ's
Is a UK double TheraPur ActiGel Polar 2000 big enough for two people?
For most couples, yes. A UK double gives 67.5cm each, which is 7.5cm less per person than the UK king. If you both sleep fairly still, it works well, helped by the wrapped pocket springs. If either of you sprawls, the UK king is the more comfortable choice.
What size bedroom do I need for a UK double TheraPur ActiGel Polar 2000?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m being a comfortable norm. That extra space is what lets you fit bedside tables on both sides and still open a wardrobe without squeezing past the bed.
How much smaller is the TheraPur ActiGel Polar 2000 double than the king?
The UK double is 15cm narrower and 10cm shorter than the UK king. For our room guidance, we suggest at least 2.7m x 2.9m for the UK king, against at least 2.6m x 2.8m for the UK double, so the king needs a slightly larger bedroom.
Should I choose the UK double or the UK small double TheraPur ActiGel Polar 2000?
If two of you share every night, the UK double is the better fit: it's 15cm wider than the UK small double and the same length. The UK small double suits a solo sleeper or a tighter room, and we suggest at least 2.4m x 2.8m for it.
What bedding fits a TheraPur ActiGel Polar 2000 double?
Standard double sheets fit the 135 x 190cm surface, and a 200 x 200cm double duvet gives good coverage for two. The mattress is 26cm deep, so check that your fitted sheet's pocket depth suits it before buying.
