Layer Details
Comfort layer
Gel foam sits over 40mm of memory foam. The memory foam contours to your shape, and the gel foam is part of the cooling technology, which should help the surface feel less warm.
Support system
3,000 pocket springs, made up of 1,000 standard springs and 2,000 mini springs. Each spring sits in its own pocket, so the base supports your body in a more tailored way beneath the foam.

Key benefits
- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who turns over constantly is simply further away and much easier to sleep through.
- Pocket springs suit the sharing life: Individual springs respond to each sleeper separately, so movement on one side is less likely to travel across 180cm of width to yours.
- Space for the whole household: When a child pads in at 3am, or a large dog treats the bed as routine, a super king absorbs the extra body without anyone perching on an edge.
- Fills a larger master properly: In a period property or a generous new build master, a UK king can look undersized; the 6ft x 6ft 6in footprint sits in proportion.
- 30cm wider than a UK king: The UK super king adds 30cm of width over the UK king at the same length, and every centimetre of that goes to the two people sharing.
This size suits you if...
You share the bed every night and one of you moves around enough to wake the other, your room comfortably clears our suggested 3m x 2.9m minimum, or your mornings regularly include a child or pet joining you and you'd rather everyone kept a proper share of the mattress.
Consider another size if...
Your bedroom is below the 3m x 2.9m we suggest for this size, or getting a 180cm wide mattress up your stairs looks doubtful. We'd recommend the UK king instead, which is 30cm narrower and needs at least 2.7m x 2.9m.

FAQ's
Is the Ice Arthur in a UK super king good for a restless partner?
It's a strong pairing. Pocket springs move independently, so your side responds to you rather than to whoever is fidgeting, and the 90cm each of a UK super king adds physical distance on top. At this width, most movement on the far side simply doesn't reach you.
How much bigger is the UK super king Ice Arthur than the UK king?
The UK super king is 30cm wider than the UK king, and the two sizes are the same length. That extra width is the difference between 90cm each and a slightly more negotiated share, which matters most if children or pets join you at night.
Is the UK super king Ice Arthur worth it over the UK double?
If two of you share, usually yes. The UK super king is 45cm wider and 10cm longer than the UK double, a substantial jump in personal space. The catch is the room: we suggest at least 3m x 2.9m for the UK super king, against 2.6m x 2.8m for the UK double.
Will a super king Ice Arthur get up my stairs?
Measure before you order. At 180 x 200cm this is a large, one-piece pocket sprung mattress, and tight landing turns or narrow loft stairs are where super kings come unstuck. Arthur Sleep doesn't publish a weight for this mattress, so check the retailer's own guidance on access before buying.
Can we share the Ice Arthur super king with a young child?
It's the size best suited to it. With 90cm each for two adults, a small visitor in the middle still leaves everyone a workable share, and the independent springs mean their wriggling disturbs you less. Just check your room clears our suggested 3m x 2.9m minimum first.
