- 90cm each for two people sharing: Each of you gets 90cm of width, which means a partner turning over at 3am happens far enough away to sleep through.
- Firm surface across a wide bed: The Decadence's firm feel holds you on top of the mattress, so even at 180cm wide there's no rolling towards the middle when someone shifts.
- Space for the whole household: When children wander in at night or a large dog treats the bed as theirs, everyone still gets a workable share of 6ft of width.
- 30cm wider than the UK king: The UK super king is 30cm wider than the UK king at the same length, and that extra width is the whole point of stepping up.
- The full 200cm length: At 200cm long, taller sleepers on their back or front, the positions this firm feel suits best, won't find their feet at the edge.
This size suits you if...
You share the bed every night and want the maximum space a standard UK size offers, your sleep is regularly interrupted by a restless partner and distance is the fix, or your mornings start with a child or dog climbing in and you'd rather everyone fitted. A large master bedroom helps too: in a generous room, a UK king can look undersized.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or the bed would dominate the space. The UK king is 30cm narrower at the same length and we'd recommend it instead; allow at least 2.7m x 2.9m for that size.

What room size do I need for a super king Sealy Decadence?
We suggest a minimum of 3m x 2.9m, and that really is a minimum: it leaves room to walk round the bed and open drawers, little more. In a larger master or a period property with a generous bedroom, the 180 x 200cm footprint sits comfortably. Measure door swing and any landing turns too, as a mattress this size makes tight corners awkward.
Is the Sealy Decadence super king big enough for co-sleeping with children?
It's the best-placed size in the range for it. With 180cm of width, a couple plus a visiting child or a dog can share without anyone hanging off the edge, and the firm surface means one person moving doesn't tilt everyone else. It won't feel roomy every night, but it stays workable in a way the UK double never would.
How much space does each person get on the super king Decadence?
You get 90cm each for two people sharing, the same width as a UK single apiece. In practice that means a restless partner can turn, stretch and steal the duvet from a genuinely comfortable distance. On a firm mattress like the Decadence, movement transfers less through the surface anyway, so the combination suits light sleepers sharing with a fidget.
Is the super king the largest size the Sealy Decadence comes in?
Yes. The Decadence comes in UK single, double, king and super king, so at 180 x 200cm, or 6ft x 6ft 6in, this is the top of the range. If you want more sleeping space than a UK king offers, this is where the line stops, and for most UK bedrooms it's as much bed as the room can take.
Should I choose the Decadence in a UK king or super king?
It comes down to your room and your nights. The UK super king is 30cm wider than the UK king; both are 200cm long. If your bedroom clears our suggested 3m x 2.9m and disturbance from a partner, child or pet is your main complaint, take the super king. If space is tighter, the UK king needs at least 2.7m x 2.9m and still sleeps two well.
