Why should you choose this mattress?
The main draw is temperature control. The graphite-infused cover is described as TheraPur's coolest ever feel, and the ActiGel foam is said to control heat better than traditional memory foam. The Platinum 3D layer adds airflow, so the mattress should be less stuffy than a standard foam-topped one. The zoned foam and PurFibre layer add cushioning for pressure relief, while individually wrapped pocket springs reduce partner disturbance. It suits most hot sleepers and couples, although lighter side sleepers may find the medium-firm feel a little firm.
Key features & 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.

Best suited for?
Warm sleepers
The graphite-infused ActiCool+ cover and breathable Platinum 3D layer work together to move heat away, so the bed should feel cooler than a standard foam-topped mattress.
Couples
Individually wrapped pocket springs reduce partner disturbance, so one person turning over is less likely to wake the other.
Combination sleepers
The Platinum 3D layer adds responsiveness, which means the mattress reacts quickly when you move and changing position through the night feels easy.
If you prefer sleeping on a soft mattress, this might not be the best choice. It's rated medium firm, and the cushioning layers are gentle rather than plush. Lighter side sleepers who like to sink in may find it too supportive. It also can't be flipped, so you only have one sleeping surface.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the TheraPur ActiGel Polar 2000?
It's rated medium firm, described as a medium to firm comfort grade. That suits back sleepers and anyone wanting solid support, although lighter side sleepers who like a softer feel may find it a little firm.
How deep is the TheraPur ActiGel Polar 2000?
It's 26cm deep. That's a fairly standard height for a mattress with this many layers, and it should sit comfortably on most bed frames, though check your frame's requirements first.
What is the TheraPur ActiGel Polar 2000 made of?
It has 2000 individually wrapped pocket springs under zoned ActiGel foam, a PurFibre comfort layer and a Platinum 3D comfort layer. A graphite-infused ActiCool+ knitted cover finishes it. TheraPur doesn't publish the layer order.
Does the TheraPur ActiGel Polar 2000 come with a trial?
Yes, Dreams offers a 100-night trial on it. It's Dreams' own offer rather than the manufacturer's, so check Dreams' full terms for how returns work before you buy.
Is the TheraPur ActiGel Polar 2000 good for hot sleepers?
It's built for them. The graphite-infused cover, heat-controlling ActiGel foam and breathable Platinum 3D layer all aim to keep you cooler. No mattress suits everyone, but it's a sensible choice if you sleep warm.
