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
- Fits a crowded bedroom: At 3ft x 6ft 3in, the UK single leaves space for a wardrobe, desk and toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Cooler sleep for warm teens: The ActiCool+ cover and ActiGel foam are designed to hold less heat than standard memory foam, which helps a teenager who kicks the duvet off every night.
- Two singles for a guest room: A pair of UK singles lets a spare room sleep two friends or siblings separately, and the medium-firm feel will suit most guests without needing a topper.
- Supportive for growing bodies: The medium-firm rating gives a steady base with gentle cushioning on top, although a very light child who sleeps on their side may find it a little firm.
- Everyday bedding fits: Standard single sheets and a 135 x 200cm single duvet fit, which makes spare sets easy to find for a student room or first flat.
This size suits you if...
You're buying for a child or teenager whose room also has to hold a desk and storage, or you sleep alone and run hot, or you're furnishing a spare room or loft conversion where only a narrow bed fits.
Consider another size if...
You share the bed, or you're tall and like to stretch out. We'd recommend the UK small double for one sleeper who wants more width, and suggest at least 2.4m x 2.8m for it.

FAQ's
Will the TheraPur ActiGel Polar 2000 single fit a bunk bed or cabin bed?
It may, but check the frame first. The mattress is 26cm deep, and bunks, cabin beds and mid sleepers usually set a maximum mattress depth so the guard rail stays high enough to be safe. Compare 26cm with the frame maker's stated limit before you order.
Is a UK single TheraPur ActiGel Polar 2000 long enough for a tall teenager?
The UK single is 190cm long, or 6ft 3in, which suits most teenagers. If they are already very tall, the UK king is 10cm longer, although it needs a much bigger room: we suggest at least 2.7m x 2.9m.
What size bedroom do I need for a TheraPur ActiGel Polar 2000 single?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk past the bed and open a wardrobe door, even in a box room or a spare room that also works as an office.
Can two people share a UK single ActiGel Polar 2000?
Not comfortably. The UK single is sized for one person. If two of you will sleep together regularly, the UK double gives 67.5cm each, and we suggest a room of at least 2.6m x 2.8m for it.
What sheets fit the TheraPur ActiGel Polar 2000 in a UK single?
Standard single fitted sheets and a single duvet (135 x 200cm) fit. Because the mattress is 26cm deep, choose fitted sheets labelled as deep enough to cover that depth so the corners stay put.
