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
- Elbow room for two: At 75cm each for two sharing, the UK king gives you 7.5cm more each than the UK double, which means fewer nudges and less clinging to the edge.
- Calmer early starts: If one of you is up hours before the other, the independent pocket springs should keep most of that movement on their side of the bed.
- Length for taller partners: At 200cm, or 6ft 6in, the UK king is 10cm longer than the UK double, so a tall sleeper can stretch out without their feet meeting the end.
- A feel two people can agree on: Komfi rates it medium, a sensible compromise when a couple with slightly different preferences has to share one surface in a UK king.
- Space during pregnancy: The extra width leaves room for a pregnancy pillow and frequent position changes without squeezing your partner towards the edge.
This size suits you if...
You share the bed every night and keep bumping into each other on a UK double, one of you is tall enough to feel cramped by a 190cm length, or your working hours differ and you'd like a little more distance from your partner's movements.
Consider another size if...
Your bedroom measures less than 2.7m x 2.9m. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Komfi Vitality Hybrid Pocket 1000 UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two sharing, a comfortable amount for adults who don't sprawl. If one of you starfishes or the dog sleeps on the bed every night, the UK super king gives 90cm each, so the UK king gives 15cm less each by comparison.
How much bigger is the Komfi Vitality Hybrid king size than a double?
The UK king is 15cm wider and 10cm longer than the UK double. Shared between two people, that works out at 7.5cm more each across the width, plus the extra length at the foot, which taller sleepers tend to notice first.
Is a UK king Komfi Vitality Hybrid long enough for tall people?
At 200cm, or 6ft 6in, the UK king suits most taller sleepers. It is 10cm longer than the UK double, and the UK super king is the same length, so if length is your main reason for upgrading, the UK king gives you it without the extra width.
What size bedroom do I need for a UK king Komfi Vitality Hybrid?
We suggest at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable once bedside tables are in. New build master bedrooms can feel smaller than the plans suggest after fitted wardrobes go in, so measure the clear floor rather than the whole room.
Should I get the Komfi Vitality Hybrid in a UK king or UK super king?
Choose the UK super king if your room allows at least 3m x 2.9m and you want maximum distance from a restless partner, since it gives 90cm each. The UK king is 30cm narrower but fits more bedrooms, and still gives 7.5cm more each than the UK double.
