Layer Details
- Cover. A breathable stretch fabric cover. It flexes with the layers beneath, so you feel the foam's contouring rather than a taut surface.
- Foam. High-performance ErgoSense foam relieves pressure and promotes healthy blood circulation, which means less tossing and turning to relieve numb spots. It's the layer that gives the mattress its medium, cushioned feel.
- Springs. Individually pocketed springs, 1,000 of them in the king size, move independently rather than as one unit. That means better spinal alignment and less disturbance when a partner shifts in the night.
- Support. DynamicEdge® active side support firms up the perimeter to maximise the usable sleep surface and prevent roll-off. Useful if you sit on the edge to dress, or share a smaller bed.

- More room each: At 75cm each for two sharing, you get 7.5cm more per person than a UK double, which means fewer elbows and less quiet negotiation over the middle.
- Length for taller partners: The UK king is 200cm long, 10cm longer than a UK double, so a partner over six foot is far less likely to have their feet at the very edge.
- Calmer early starts: The 1,000 individually pocketed springs in this size move independently, so when one of you gets up at dawn, the partner still asleep should feel much less of it.
- A usable full width: DynamicEdge side support firms up the perimeter, which means you can use the whole 150cm without drifting towards the middle for fear of the edge.
- Room for the bed, and for you: We suggest at least 2.7m x 2.9m for a UK king, slightly less floor space 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 keep waking when your partner moves, or one of you is over six foot and has run out of length on a double. It also helps if your schedules differ and one of you is up hours before the other.
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, and we suggest at least 2.6m x 2.8m for it.

Is the Sleep Story Ergo Deluxe UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two sharing, which is 7.5cm more per person than a UK double. That sounds small on paper, but it is the difference between brushing against each other all night and having a little space of your own.
Is the Ergo Deluxe king size long enough if you're over 6ft?
It should suit most tall sleepers. The UK king measures 150 x 200cm, or 5ft x 6ft 6in, and it is 10cm longer than a UK double. If one of you is tall, that extra length is often the real reason to upgrade, with the width a welcome bonus.
Will I feel my partner move on the Sleep Story Ergo Deluxe UK king?
Probably less than on a smaller bed. The UK king version has 1,000 individually pocketed springs that respond separately, and you each have 75cm of width, so there is more distance between you as well. A restless partner won't become invisible, but early risers should disturb the other side far less.
Is it worth upgrading from a UK double to the Ergo Deluxe UK king?
If you are both feeling cramped, it usually is. You gain 15cm of width and 10cm of length over a UK double. The catch is room size: we suggest at least 2.7m x 2.9m for a UK king, compared with 2.6m x 2.8m for a UK double, so measure first.
Should I get the Sleep Story Ergo Deluxe in a UK king or super king?
The UK king suits most couples. The UK super king is the same length but gives 15cm more width each, and we suggest at least 3m x 2.9m for it. Choose the super king if space is plentiful and you want real distance; otherwise the UK king is the more practical fit.
