Key benefits
- Room to spread out: With 75cm each for two people sharing, the UK king gives you 7.5cm more each than the UK double, which means fewer knocked elbows and less clinging to the edge.
- Calmer nights on different schedules: Individually wrapped springs keep movement mostly on one side, so a partner leaving for an early shift is less likely to jolt you awake.
- Extra length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot can stretch out without their feet reaching the end.
- Easy to check in feet: The UK king measures 5ft x 6ft 6in, which is handy if your current frame or headboard is listed in imperial measurements.
- More space without the biggest room: We suggest a bedroom of at least 2.7m x 2.9m, a little less than the 3m x 2.9m we suggest for the UK super king.
This size suits you if...
You share the bed every night and have started to feel cramped on a UK double, one of you gets up hours before the other, or a taller partner needs the extra length but your bedroom can't take a UK super king.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once furniture is in. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the SleepSoul Heaven 1000 UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two people sharing, which is 7.5cm more each than the UK double. If you both sprawl, or a child or dog often joins you, the UK super king gives 90cm each, although that means 15cm less each on the UK king by comparison.
Will I feel my partner moving on the SleepSoul Heaven 1000 in a UK king?
Less than you would on an open coil bed. Pocket springs react individually, so a partner turning over or getting up early tends to stay on their own side. The UK king adds 7.5cm more each than the UK double, which puts a little more distance between you as well.
Is the SleepSoul Heaven 1000 king size long enough for tall people?
The UK king is 200cm long, 10cm longer than the UK double and the UK small double. That extra length suits a partner over six foot who finds their feet at the edge on a shorter bed. The UK super king is the same length, so sizing up adds width only.
Should I get the SleepSoul Heaven 1000 in a UK king or a UK super king?
Choose the UK king if your room is tighter: we suggest at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king. The UK super king is 30cm wider and gives 90cm each, which suits restless sleepers, but both sizes share the same length.
Will a UK king SleepSoul Heaven 1000 fit in a new build master bedroom?
Often, but measure after the wardrobes go in, as fitted storage can take more floor than the plans suggest. Allow at least 2.7m x 2.9m, with 3.2m x 3.2m comfortable. If the room falls short, the UK double needs at least 2.6m x 2.8m by our guidance.
