- Real distance from a restless partner: With 90cm each for two people sharing, movement on one side simply happens too far away to wake you.
- Space for the whole household: Children padding in at night, or a large dog treating the bed as routine, no longer means someone sleeping on the edge.
- Noticeably wider than the UK king: The UK super king is 30cm wider than the UK king, which is the difference between comfortable and genuinely undisturbed for two adults.
- Pocket springs across a big surface: The 1,000 encapsulated 16cm pocket springs respond independently, so a wide bed doesn't turn into one shared trampoline.
- Fills a large master properly: In a period property or generous main bedroom, a UK king can look undersized; at 6ft x 6ft 6in this size sits in proportion.
This size suits you if...
You share the bed every night and one of you is a light sleeper, your children or pets regularly join you and a UK king already feels crowded, or you have a large master bedroom where a smaller bed would look lost. It also suits couples on a budget who want maximum space without paying premium-hybrid money.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you sleep alone. We'd recommend the UK king instead: still generous for two, and an easier fit in most rooms.

How big is the Otty Essential Hybrid super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That's the largest size Otty offers for this mattress, and the biggest size stocked as standard in the UK. Two people sharing get 90cm each, which is the same width per person as a UK single.
Is the super king Otty Essential Hybrid worth it for restless sleepers?
It's the strongest case for this size. The encapsulated pocket springs limit how far movement travels, and the sheer width does the rest: with 90cm each, your partner's turning happens at a distance no comfort layer can match. If broken sleep from a fidgety partner is your main complaint, size solves it better than firmness.
Will a super king mattress fit in my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables and walking space. Measure the door swing and any landing turns too; at this size, getting the mattress upstairs deserves as much thought as the room itself.
Does the Otty Essential Hybrid super king work for families sharing with children?
Yes, this is where the size makes sense. When a child wanders in at night, a UK king leaves someone clinging to the edge; the extra width of the UK super king means everyone keeps a workable share. The same logic applies if a large dog has claimed a spot as routine.
Where can I buy the Otty Essential Hybrid in a super king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. One practical note at this size: super king bedding is sold by fewer shops and costs more, so budget for a 260 x 220cm duvet and sheets alongside the mattress itself.
