- Distance plus low motion transfer: The encapsulated springs already limit movement across the bed, and at 90cm each for two people sharing, a fidgeting partner is a long way away anyway.
- Room for night-time visitors: When a child pads in at 3am, or a large dog treats the bed as routine, 180cm of width means everyone still gets a workable share.
- Firm edges you can actually use: Spring encapsulation stiffens the sides, which matters more at this size because outer positions become real sleeping space rather than a nervous perch.
- Cooler across a bigger surface: Temperature regulating memory foam and airflow side supports help warm sleepers, and the extra width lets two hot bodies spread out rather than share heat.
- Support that holds at scale: The 16cm springs and Medium-Firm 7/10 feel deliver proper spinal support for back and front sleepers right across the wider surface.
This size suits you if...
You share the bed every night and a UK king still feels crowded, your partner is restless enough that distance matters more than any comfort layer, or children and pets regularly join you and you want everyone to keep their own space. Your room should offer at least our suggested 3m x 2.9m, ideally more.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you sleep alone and the space would go unused. The UK king would suit you better: it is 30cm narrower and the same length, so it fits far more rooms.

What room size do I need for a super king Otty Hybrid?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once you allow for bedside tables and door swing. In a loft conversion, check where the slope falls too, as it often decides which wall a 180cm wide bed can sit against.
Is the Otty Hybrid super king big enough for co-sleeping with children?
It is the most practical mainstream size for it. At 180 x 200cm you get 90cm each for two people sharing, so a child wandering in at night borrows space without leaving either adult clinging to an edge. The firm encapsulated sides also make the outer positions properly usable.
Will the Otty Hybrid in a UK super king fit up my stairs?
It arrives rolled and boxed, which helps, but at this size the box is heavy and awkward for one person. Measure tight landing turns and doorways before ordering, and plan for two people to carry it. Once unrolled, a 180 x 200cm mattress is very difficult to move again.
How much wider is a super king than a king?
The UK super king is 30cm wider than the UK King, and the two are the same length at 200cm. That extra width is the difference between occasionally touching a restless partner and sleeping genuinely undisturbed, which is where the low motion transfer of the 16cm springs pays off.
What bedding fits the Otty Hybrid super king?
You'll need super king sheets and a 260 x 220cm duvet. Bedding at this size costs more and takes longer to dry than smaller sizes, which is a running cost people sometimes forget. The mattress itself has a removable knitted cover, handy given how hard a 180cm mattress is to manoeuvre for cleaning.
