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
- 90cm each for two: Each sleeper gets 90cm, which is 15cm more each than on the UK king, so turning over and stretching out happen on your own side of the bed.
- Space for a small visitor: When a child climbs in after a bad dream, the 180cm width leaves enough room that nobody spends the rest of the night clinging to the edge.
- Distance from a restless partner: The 2000 pocket springs reduce how much movement carries across the mattress, and the extra width puts more distance between you and someone who tosses and turns.
- Help with shared body heat: A graphite-infused cover and a breathable Platinum 3D layer help with airflow, which counts for more when a child or the dog adds warmth to a big bed.
- Bedding big enough for everyone: Super king sheets and a 260 x 220cm duvet fit, so a family-sized bed is less likely to end in someone tugging the covers away at night.
This size suits you if...
You share with a partner who rarely lies still, or a young child or a large dog regularly ends up in the bed, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room measures under 3m x 2.9m, or a sloping ceiling in a loft conversion leaves too little full-height wall. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a TheraPur ActiGel Polar 2000 UK super king fit in my bedroom?
Allow at least 3m x 2.9m for the UK super king. That figure is our own guidance rather than TheraPur's. At 180 x 200cm, or 6ft x 6ft 6in, the mattress also needs clearance for the door swing and bedside tables. Measure with the door fully open, because that is usually where the space runs out first.
Is a UK super king worth it over a UK king for a restless partner?
The UK super king gives 90cm each, against 75cm each on the UK king, so you get 15cm more per person. Pocket springs reduce movement transfer rather than stopping it, and extra distance helps when a partner turns over often. Both sizes are the same length, so taller sleepers gain nothing lengthways by sizing up.
Can a child sleep in a super king with two adults?
Often, yes, while the child is young. At 180cm wide, the TheraPur ActiGel Polar 2000 in a UK super king leaves more spare width than any smaller size of this mattress, so a small child can sleep between you without either adult being pushed to the edge. Older children will make it feel crowded fairly quickly.
Will a UK super king mattress get up my stairs?
Measure the landing turn and the bedroom doorway before you order. The UK super king is 180 x 200cm and 26cm deep, and on a narrow landing the width is usually the measurement that decides it. Once you're confident it will make the turn, compare the retailers listed on this page.
What size duvet fits a TheraPur ActiGel Polar 2000 super king?
A 260 x 220cm duvet fits, along with super king fitted sheets. Choose fitted sheets with enough depth for a 26cm mattress so the corners stay put. The wider duvet also means a partner who rolls about is less likely to pull the covers off you during the night.
