Layer Details
Cover
A breathable micro-quilted knitted fabric cover that enhances airflow. That helps heat escape rather than build up around you overnight.
Comfort layer
High-performance ErgoSense foam that relieves pressure and promotes healthy blood circulation. In practice, this means cushioning at your hips and shoulders where you press in most.
Support layer
1500 individually encased pocket springs providing the underlying support. Because each spring moves on its own, you feel less of a partner's movement across the bed.
Encapsulation
The springs are fully foam-encapsulated for a wider sleep surface and edge-to-edge support. You can sleep close to the edge without that rolling-off feeling.

Key benefits
- Room to spread out: The UK king is 15cm wider than the UK double, so each of you gets 7.5cm more, enough to stop elbows meeting at 2am.
- Length for taller sleepers: At 200cm long, your feet stay on the mattress rather than hanging off the end, which a 190cm UK double can't always promise someone near six foot.
- Quieter early starts: The 1500 individually encased springs absorb movement locally, so a partner leaving the bed hours before you is less likely to wake you.
- Usable to the edge: Full foam encapsulation around the springs means the outer strip of a UK king supports you too, so you can sleep near the edge without that rolling-off feeling.
- More space without a super king room: The UK king is 30cm narrower than the UK super king, so it fits bedrooms where the bigger bed would leave no room to walk around.
This size suits you if...
You share the bed every night and keep ending up in each other's space on a UK double, one of you gets up much earlier than the other, or one of you is over six foot and tired of feet hanging off the end.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is a UK king Sleep Story Hybrid 360 long enough for someone over 6ft?
At 200cm (6ft 6in), the UK king is 10cm longer than the UK double, the UK small double and the UK single. For most people around six foot that leaves a comfortable margin at the foot end. The UK super king is the same length, so sizing up adds width, not length.
How much space does each person get on a king size Sleep Story Hybrid 360?
Two people sharing the UK king get 75cm each. That's 7.5cm more each than on the UK double, which gives 67.5cm each. If you want more, the UK super king gives 90cm each, though it needs a noticeably bigger room.
Will I feel my partner moving on the Sleep Story Hybrid 360 king?
Less than on many sprung mattresses. The springs are individually encased, so a partner turning over or getting up mostly moves the springs beneath them. On a UK king there's also more distance between you, which helps if you keep different hours.
What size bedroom do I need for a Sleep Story Hybrid 360 in UK king?
We suggest at least 2.7m x 2.9m. In a new build master bedroom, measure after fitted wardrobes, as they can eat the space quickly. If you fall short, the UK double needs at least 2.6m x 2.8m.
Should I get the Sleep Story Hybrid 360 in king or super king?
The UK super king is 30cm wider and gives 90cm each, but the two sizes are the same length. If your problem is length, the UK king solves it. If you share with a dog or a restless sleeper, the UK super king may help, provided your room has at least 3m x 2.9m.
