Key benefits
- A full 90cm each: Sharing the UK super king gives each of you 90cm, which means a restless partner's turning happens further from you rather than right beside your shoulder.
- 15cm more each than a UK king: The UK super king is 30cm wider than the UK king at the same length, so each sleeper gains 15cm without the bed getting any longer.
- Room for a small visitor: When a child pads in after a bad dream, a 6ft wide surface lets them settle between you without anyone ending up clinging to the edge.
- Space for a dog that sleeps over: If a large dog joins you most nights, the extra width means it can stretch out at the foot or side while you both keep your own patch.
- Extra length over a UK double: At 200cm long, the UK super king is 10cm longer than the UK double, so taller sleepers are less likely to find their feet hanging off the end.
- Suits a large master bedroom: In a period property or a spacious new build master, a UK super king fills the room in proportion where a UK king can look slightly lost.
This size suits you if...
You share with someone who fidgets, kicks or gets up early and you want real distance between you, or a child or a large dog regularly ends up in your bed. It also fits well if your bedroom measures at least 3m x 2.9m and a smaller bed would look undersized against the walls.
Consider another size if...
Your bedroom is under 3m x 2.9m, or a sloping loft ceiling limits which wall the bed can go against. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Blueberry Hybrid super king big enough for two adults and a child?
For occasional night-time visits, yes. Two adults sharing a UK super king get 90cm each, so a small child can tuck in between without either of you being pushed to the edge. If a child sleeps with you every night as they grow, things get tighter, although no wider size is sold as standard in the UK.
What room size do I need for a super king Hyde & Sleep Blueberry Hybrid?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling comfortable once bedside tables are in. Check the door swing clears the corner of the bed, and in a loft conversion work out which wall has full headroom before you order.
How much bigger is a super king than a king in the Blueberry Hybrid?
The UK super king is 30cm wider than the UK king and the same length, at 180 x 200cm. Shared between two, that gives each of you 15cm more. The UK king needs at least 2.7m x 2.9m by our guidance, against 3m x 2.9m for the UK super king.
What size duvet and sheets fit a super king Blueberry Hybrid?
You'll need super king fitted sheets and a 260 x 220cm duvet. The mattress is 24cm deep, so choose fitted sheets with enough depth to grip the corners securely. If you're moving up from a smaller bed, your existing bedding won't fit, so plan for a full new set.
Will a UK super king help if my partner is a restless sleeper?
Distance is the simplest fix for a fidgety partner, and the UK super king gives you 90cm each, 22.5cm more each than a UK double. Measure your landing turns and door frames first, then compare the retailers listed on this page for the Blueberry Hybrid in this size.
