Key Benefits of the TheraPur ActiGel Arctic 3000 Combination Super King Mattress

  • Room for a restless partner: With 90cm each, a partner who turns all night is further away, and the pocket and micro springs help soak up the movement that does reach you.
  • Space when the family piles in: If a small child arrives at 3am, nobody has to cling to the edge, because the UK super king is 30cm wider than the UK king.
  • A firm surface across a wide bed: The firm feel suits back sleepers who like to lie flat, and zoned ActiGel foam eases pressure at the shoulders and hips.
  • Cooler for two bodies: Two people put out a lot of heat in one bed, so the graphite-infused cover, designed to keep the surface cooler, is a sensible match for this size.
  • In proportion in a large master: In a period bedroom with high ceilings or a generous new master, a UK king can look a little lost, while 6ft of width fills the space properly.

Who should buy the TheraPur ActiGel Arctic 3000 Combination Super King Mattress?

This size suits you if...

You share the bed every night with someone who moves a lot and you want real distance between you, your children or a large dog regularly join you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.

Consider another size if...

Your bedroom is under 3m x 2.9m, or the stairs are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

How much space per person does the TheraPur ActiGel Arctic 3000 super king give?

The UK super king gives 90cm each for two people sharing. Compared with the UK king, that's 15cm more each, and compared with the UK double it's 22.5cm more each. If a restless partner is your main reason for upgrading, that extra distance does more than any comfort layer can.

What size room do I need for a UK super king mattress?

We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m feels more comfortable once you add bedside tables and space to walk around. In a loft conversion, check which wall gives full head height at the sides of the bed before you commit.

Is the UK super king worth it over the UK king for a couple with kids?

If children or a dog regularly join you, yes. The UK super king is 30cm wider than the UK king at the same 200cm length, so a small visitor fits without pushing anyone to the edge. If it's just the two of you and the room is tight, the UK king is the easier fit.

Will a super king mattress fit up my stairs?

It's a full 180cm wide, so measure the tightest landing turn and the way the bedroom door swings, as well as the doorway itself. Hotel-style zip and link beds use two 90cm singles side by side, so check with the retailer how this mattress is delivered before you measure.

What bedding fits a TheraPur ActiGel Arctic 3000 super king?

You'll need super king sheets and a 260 x 220cm duvet. Bedding at this size can cost noticeably more than a UK king set, so factor it in alongside the mattress itself. Therapur doesn't publish a depth, so check fitted sheet depth against the mattress once it arrives.
