Pocket Springs
1,200 pocket springs form the core of the mattress, and the body-moulding nature of the spring system means the surface adapts to your shape as you move. Each spring works independently, so support goes where your body needs it.

Key benefits
- 90cm of width each: Two people sharing get 90cm each, which means a restless partner rolling over happens far enough away that you're unlikely to register it.
- Springs that isolate movement: The 1,200 pocket springs move independently, so at this width one side of the bed can shift without the disturbance travelling across to yours.
- Space for the whole household: If children wander in during the night or a large dog treats the bed as its own, a super king absorbs the extra body without anyone perching on an edge.
- Fills a large master properly: In a period property or generous new build master, a UK king can look lost against the wall; the super king sits in proportion.
- Support across the full surface: The body-moulding spring system works wherever you press into it, useful on a bed this wide where sleepers spread out rather than share the middle.
This size suits you if...
You share the bed every night and one of you sleeps restlessly, so distance matters as much as comfort. Or your household regularly ends up sharing, children padding in at 3am or a dog that claims the foot of the bed, and everyone still needs their own patch. It also suits you if your master bedroom is large enough that a smaller bed would look undersized.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for a UK super king. The UK king is 30cm narrower and the same length, and we'd recommend it instead; allow at least 2.7m x 2.9m for that size.

FAQ's
Is the Hypnos Cotton Origins 7 super king big enough for a family sharing the bed?
It's the most forgiving size for it. At 180 x 200cm, two adults get 90cm each, so a child climbing in at night borrows space rather than taking someone's entire side. The 1,200 pocket springs also respond independently, meaning a small body wriggling in the middle disturbs the surface less than a mattress that moves as one unit.
What room size do I need for a super king Hypnos Cotton Origins 7?
We suggest at least 3m x 2.9m, and that's our guidance rather than a Hypnos figure. That minimum leaves walking space around the bed but little more; if you want bedside tables on both sides and a chest of drawers, a larger room feels considerably more comfortable. Measure the room, then mark the 180 x 200cm footprint on the floor.
How much bigger is the UK super king than the UK king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. That 30cm all goes into sleeping width, taking each sharer from a decent allowance to 90cm each. If your room meets our suggested 3m x 2.9m minimum for the UK super king, the extra width is usually the better buy for couples.
Does a super king actually help with a restless partner?
More than any comfort layer can. With 90cm each, most movement simply happens too far away to wake you, and this mattress adds a second defence: its 1,200 pocket springs compress individually, so motion stays on the side that caused it. If broken sleep from a fidgeting partner is your main complaint, size is the fix, and this is the biggest standard size sold.
Will the Hypnos Cotton Origins 7 super king get up my stairs?
This is the size where access bites. A 180 x 200cm mattress is awkward on narrow staircases, tight landing turns and small door swings, so measure the whole route, including any turn at the top, before ordering. Hypnos doesn't publish handling guidance on the listing we've sourced, so ask the retailer about access requirements before committing.
