Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, which means a partner who turns over all night is happening at a distance rather than against your back.
- Room for night-time visitors: If children wander in during the small hours, or a large dog treats the bed as its own, 180cm of width means nobody ends up clinging to the edge.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK king at the same 200cm length, a difference you feel every night if you currently share a smaller bed.
- Fills a large master properly: In a period property or a big new build main bedroom, a UK king can look undersized; this footprint suits the room as well as the sleepers.
- Foam construction at this scale: The temperature-regulating cover and zoned HRX foam base come in the same build as smaller sizes, so sizing up changes your space, not the feel.
This size suits you if...
You share the bed every night and want the most space a standard UK size can offer, your partner is restless enough that distance matters more than any comfort layer, or your household routinely includes children or pets in the bed by morning. It also suits you if you have a large master bedroom where a smaller bed would look lost, and you'd rather reach that size on a tighter budget.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 3m x 2.9m, or you sleep alone. We'd recommend the UK king instead: still 200cm long, but easier to fit and to dress.

FAQ's
What size room do I need for the Emma Essential super king?
We suggest allowing at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add walking space and bedside tables on both sides. Before you order, check the awkward bits too: door swing, landing turns and stair angles only start to bite at this size.
How much bigger is the Emma Essential super king than a UK king?
The UK super king is 30cm wider than the UK king, at 180cm against 150cm, and both are 200cm long. That extra width is the whole point of sizing up: two people sharing get 90cm each, which is where a fidgety partner stops being your problem.
Is the UK super king the largest size the Emma Essential comes in?
Yes. The Emma Essential comes in five UK sizes, from single up to super king, and this is the biggest of them. If you want maximum sleeping space from this mattress, the UK super king at 180 x 200cm is as far as the range goes.
Is a UK super king big enough for a couple with young children joining them?
It's the best-placed standard size for it. Two adults get 90cm each, so when a child wanders in at 3am there's still a workable share for everyone. No mattress makes three sleepers feel roomy, but at 180cm wide this one comes closest without going made to measure.
Where can I compare prices for the Emma Essential super king?
Use the price table on this page. The prices shown here are updated as retailers change them, so it's a more reliable guide than any figure written into the text. Availability of the UK super king can differ from smaller sizes, so it's worth checking before you settle on this one.
