Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, which means you can sleep on the same mattress without feeling crowded.
- Distance does most of the work: The pocket springs move independently, but the extra width is what really helps with a restless partner, because their elbows and knees rarely reach your side.
- Room for a small visitor: If a child wanders in during the night, the UK super king can take a third body without anyone ending up clinging to the edge.
- 15cm more each than a UK king: The UK super king is 30cm wider than the UK king and the same length, which gives each sleeper 15cm more width.
- Sized for a big bedroom: In a large master bedroom or a period property with high ceilings, a UK king can look a little lost, while the UK super king fills the space properly.
This size suits you if...
You share the bed every night and one of you tosses and turns, or your children or dogs regularly end up in it by morning. It also suits you if your bedroom comfortably clears 3m x 2.9m and you want each sleeper to have 90cm of width.
Consider another size if...
Your bedroom is tighter than 3m x 2.9m, or a narrow landing makes a 180cm wide mattress a struggle to carry up. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the SleepSoul Heaven 1000 super king big enough for two adults and a child?
For the occasional night visit, usually yes. Two adults get 90cm each on the UK super king, so a small child can squeeze into the middle and you still keep some space. If a child joins you every night, bear in mind that the 180cm width is shared between three people, so each of you will have less than 90cm.
UK king or UK super king for a partner who moves a lot?
If your room allows it, choose the UK super king. It gives each sleeper 15cm more width than the UK king, which is 75cm each. The Heaven 1000's pocket springs reduce how much movement travels across the mattress, but extra space between you makes the bigger difference.
Will a UK super king fit in a loft conversion bedroom?
Check the usable floor area rather than the full footprint of the room. Sloping ceilings often mean only one wall has enough headroom for a bed. We suggest at least 3m x 2.9m for a UK super king, so measure the full-height section. If that falls short, the UK king needs at least 2.7m x 2.9m.
Is the UK super king Heaven 1000 longer than a UK double?
Yes. The UK super king is 200cm long, which is 10cm longer than the UK double, and it is also 45cm wider. That extra length helps taller sleepers keep their feet on the mattress. The UK king is the same length, so the gain from sizing up from a UK king is width only.
Can a large dog share a UK super king with two people?
It's the most practical size for that. With 90cm per person, a large dog can settle at the foot of the bed or between you without pushing either of you towards the edge. The Heaven 1000 has only 2cm of quilting on top, so you may feel a heavy dog shifting about a little.
