Key benefits

Key Benefits of the TheraPur ActiGel Arctic 3000 Combination Double Mattress

  • Sized for an ordinary bedroom: We suggest a room of at least 2.6m x 2.8m, which means most UK main bedrooms can take this mattress and still fit a wardrobe and a chest of drawers.
  • Room for bedside tables: In a room of around 3m x 3m, you should be able to keep a bedside table on each side, so neither of you is reaching over the other for a lamp.
  • Less disturbance at close quarters: With 67.5cm each, you lie nearer your partner, which makes the motion-absorbing pocket and micro springs more useful on a UK double than on wider sizes.
  • A cooler surface for two: Two people on a shared surface generate more warmth, and the graphite-infused cover is designed to help keep the top of the mattress feeling cooler.
  • Easy bedding: Standard double sheets fit, and a 200 x 200cm double duvet covers it, so you can probably reuse the bedding you already own.

Who should buy the TheraPur ActiGel Arctic 3000 Combination Double Mattress?

This size suits you if...

You share a bed every night with a partner who likes a firm surface and your bedroom is close to our suggested minimum of 2.6m x 2.8m. It also suits you if you sleep alone and want a firm surface with room to stretch out, even when the cat claims a corner.

Consider another size if...

You and your partner are both broad-shouldered or restless, and your room has space to spare. We'd recommend the UK king instead, which gives 75cm each. Allow at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

Is a UK double TheraPur ActiGel Arctic 3000 big enough for two adults?

For most couples, yes. You get 67.5cm each, which is 7.5cm less per person than a UK king. That's comfortable if you both sleep fairly still. The springs help by limiting how much movement crosses the bed, but if either of you sprawls, you'll feel the edges sooner than on a wider size.

What size bedroom do I need for a UK double TheraPur ActiGel Arctic 3000?

We suggest at least 2.6m x 2.8m. That leaves enough floor to walk round the bed and open a wardrobe. If you want a bedside table on each side and some breathing room, around 3m x 3m feels far less cramped. Measure with the doors open, as a swinging wardrobe door can eat into the gap quickly.

How big is the TheraPur ActiGel Arctic 3000 double in feet and inches?

It measures 4ft 6in x 6ft 3in, or 135 x 190cm. That's the same length as the UK single and UK small double, and 10cm shorter than the UK king. If either of you is tall and your feet already reach the end of your current bed, the extra length of the UK king may be the more useful upgrade.

Should I choose the UK double or UK king TheraPur ActiGel Arctic 3000?

The UK double is 15cm narrower and 10cm shorter than the UK king, so it's the better choice when floor space is tight. For the UK king, we suggest at least 2.7m x 2.9m. If your room clears that comfortably and you often wake each other, the UK king gives you both more space.

Is a UK double TheraPur ActiGel Arctic 3000 a good choice for a guest room?

It works well for visiting couples, and it's 15cm wider than the UK small double. Bear in mind that it's rated firm. Guests who sleep on their side and like to sink in may find it unyielding. If the guest room is small, the UK small double needs at least 2.4m x 2.8m.
