HD foam comfort layers
Two HD foam layers sit on top and are described as breathable. That gives you a comfortable surface with less heat build-up.
1000 pocket spring system
Independent pocket springs that shape to the contours of your body. Each spring works on its own, so the mattress supports you where you need it.
Ecofoam base
A high-density foam foundation made from 100% recycled foam offcuts. It gives the springs a supportive base and uses recycled material.

Key benefits
- 90cm each when you share: Each of you gets 90cm, which is 15cm more per person than the UK king, so a restless partner can turn over without ending up on your side.
- Movement stays where it starts: The 1000 pocket springs work individually, which means a child wriggling in the middle presses down there rather than the whole 180cm surface dipping as one piece.
- No longer than a UK king: It shares the 200cm length of the UK king, so moving up from a king asks your room for 30cm more width but no extra space at the foot.
- Space for a large dog: If a big dog sleeps on the bed every night, the 6ft width leaves both of you a proper share rather than a narrow strip along each edge.
- In proportion in a large room: In a period property or a generous master bedroom, a UK super king sits comfortably against the wall where a UK king can look slightly undersized.
This size suits you if...
You share with a partner who tosses and turns and want real distance between you, or children and a large dog regularly end up in the bed with you and your bedroom comfortably clears 3m x 2.9m.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m, or you sleep alone most nights. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Komfi Vitality Hybrid Pocket 1000 UK super king big enough for two adults and a child?
Two adults get 90cm each across the 180cm width, so a small child tucked in between still leaves everyone some room. The independent pocket springs help as well, because movement stays closer to where it happens. Sharing every night with an older child is still a squeeze, even at this size.
What room size do I need for a Komfi Vitality Hybrid super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once bedside tables and a wardrobe go in. In a loft conversion, work out where the slope falls before anything else, since you'll want standing height on at least one side of the bed to get in and out easily.
UK super king vs UK king: how much extra space do you get?
The UK super king is 30cm wider than the UK king but the same 200cm length. For two people sharing, that's 90cm each against 75cm each, so 15cm more per person. If one of you kicks or turns a lot, that extra gap is usually what tips the decision.
What bedding fits a super king Komfi Vitality Hybrid mattress?
You'll need super king fitted sheets and a 260 x 220cm duvet. The mattress is 25cm deep, so check fitted sheets have pockets deep enough to tuck well under. If you're moving up from a smaller bed, plan for a full new set, as super king bedding costs more than smaller sizes.
Will a UK super king mattress fit up my stairs and through the door?
The mattress itself comes boxed, but the bed frame it sits on is 180cm wide, so measure doorways and the turn on your landing before you order. Check which way the bedroom door swings once a UK super king frame is in place too. Once you're sure it fits, compare the retailers listed on this page.
