Layer Details
- Microquilted cover. A quilted cover made with eco-friendly Tencel®, a natural fabric that helps control moisture, so the surface stays drier through the night. It's also a gentle choice if you have sensitive skin.
- Reflex foam. A layer of Reflex foam, a firmer, more responsive alternative to memory foam. You get cushioning without the slow, sinking feel, which suits people who move around in the night.
- Open coil springs. Open coil springs form the support core, with reinforced sprung edges so you can use the full width of the mattress without the sides collapsing. This is what gives the mattress its firm, supportive feel.

- More distance from a restless partner: With 90cm each, 15cm more per person than the UK king, you have more room to drift away from a partner whose movements travel through the open coil springs.
- Edges you can actually sleep on: Reinforced sprung edges keep the outer strip of the bed supportive, which helps when a child or dog has claimed the middle and you end up near the side.
- A drier surface with a crowded bed: The Tencel cover draws moisture away from the surface, which means less clamminess on nights when a child or pet joins you and the bed gets warmer.
- In proportion with a large room: At 6ft x 6ft 6in, the UK super king fills a large master or period bedroom in a way a UK king can leave looking slightly lost.
- All the extra space goes into width: It shares the 200cm length of the UK king, so the additional 30cm is entirely sideways room, which suits couples who have outgrown a king and want more elbow space.
This size suits you if...
You share with a partner who tosses and turns and want as much distance between you as possible, children or a large dog regularly end up in the bed, or your bedroom is big enough that a UK king would look undersized.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead; we suggest at least 2.7m x 2.9m for it.

Will I feel my partner move on the Sleep Story Cool Sleep in a UK super king?
Open coil springs move as one unit, so some movement will still reach you. What the UK super king adds is distance: 90cm each, which is 15cm more per person than the UK king. If your partner is very restless, that extra gap is the most practical help this mattress offers.
Is a UK super king Sleep Story Cool Sleep big enough for two adults and a child?
It is the widest size of this mattress, at 180cm. With three of you it will feel snug rather than roomy, but the reinforced sprung edges keep the outer strip supportive, so whoever is pushed to the side is less likely to feel they are rolling off.
How much wider is the Sleep Story Cool Sleep super king than the UK king?
The UK super king is 30cm wider and the same 200cm length, which gives two sharers 15cm more each. We suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king, so measure your room width before choosing.
Is a Sleep Story Cool Sleep super king good if my dog sleeps on the bed?
It gives you the most room of any size in this range, which helps when a large dog takes its share as a matter of routine. The Tencel cover helps keep the surface drier, and the reinforced sprung edges mean you still have usable support if the dog claims your side.
Does the Sleep Story Cool Sleep come in a size bigger than a super king?
No. The UK super king, at 180 x 200cm, is the largest of the six sizes this mattress is made in. If you need more width than 6ft, you would have to look at a different model altogether.
