Key benefits
- Room to sleep apart, together: With 90cm each for two people sharing, a restless partner is far enough away that the springs barely need to absorb their movement.
- Space for night-time visitors: When a child pads in at 3am, a UK super king absorbs the extra body without anyone ending up on the edge.
- Springs where movement matters most: The mini pocket spring layer responds to each sleeper individually, which helps across a width this generous where two people rarely move in sync.
- Fills a larger bedroom properly: In a big master where a UK king can look undersized, the 6ft x 6ft 6in footprint sits in proportion with the room.
- A cooler bed with more surface: The moisture-wicking UltraDry cover and breathable Airgocell foam spread across 180cm of width, so two warm sleepers aren't trapping heat in one spot.
This size suits you if...
You share the bed every night and want the maximum space a standard UK size offers, you sleep next to someone genuinely restless and have realised distance matters more than any comfort layer, or your household includes children or pets who treat your bed as theirs and you'd rather plan for that than fight it.
Consider another size if...
Your bedroom is under our suggested minimum of 3m x 2.9m, or you'd struggle to get a mattress this size around your landing or up a loft staircase. The UK king, 30cm narrower, would suit you better and still gives a couple generous room.

FAQ's
Is the Emma Hybrid super king big enough for co-sleeping with a child?
It's the best size for it that's stocked as standard. At 180 x 200cm, two adults get 90cm each, so a small child joining you takes a share from both sides rather than pushing one adult to the edge. It won't feel spacious with a visitor, but everyone keeps a workable slice of mattress.
What room size do I need for the Emma Hybrid in a UK super king?
We suggest allowing at least 3m x 2.9m, and a room around 3.5m x 3.2m feels more comfortable, leaving space to walk round both sides and open drawers. In a loft conversion, check the sloping ceiling too: a 200cm-long mattress limits which wall the bed can sit against.
Will the Emma Hybrid super king stop me feeling my partner move?
Two things help here. The mini pocket springs respond to each sleeper separately, and the memory foam layer absorbs some motion before it travels. The bigger factor is simply width: with 90cm each, most of your partner's tossing happens too far away to reach you. It's the size we'd point restless couples towards.
Should I get the Emma Hybrid in a super king or a UK king?
If your room clears our suggested 3m x 2.9m minimum and you share with a partner, child or dog, the UK super king is the safer buy, as it's 30cm wider than the UK king. If space is tighter or you sleep alone, the UK king is plenty and easier to manoeuvre upstairs.
Is a super king mattress harder to buy bedding for?
Slightly. Super king sheets and the 260 x 220cm duvet that suits this size are stocked by fewer shops than double or king bedding, and tend to cost a little more. It's a running cost worth budgeting for, though most larger retailers carry the size, so it's an inconvenience rather than a real obstacle.
