Layer Details
- Sleep surface. A naturally hypoallergenic fabric that feels soft against the skin. A gentle starting point for sensitive or allergy-prone sleepers.
- Airloft™ comfort layer. A foam alternative made from lightweight, open non-woven fibres, which the brand says is 18x more breathable. It mimics the feel of countless tiny springs, gently contouring to your body and spreading your weight evenly.
- 1000 Mini springs. A layer of 1,000 mini springs that respond to even slight movements, which means the surface adjusts as you shift in the night. They also add airflow through the middle of the mattress.
- Comfort Breathe®. Fibres described as 15x more breathable than standard memory foam. They promote airflow and help regulate temperature, a real plus if you tend to overheat.
- 600 Mirapocket spring unit. 600 pocket springs held in individual fabric pockets, each responding independently to your body. That gives you zoned support and better spinal alignment, and less disturbance from a restless partner.
- Protective layer. Disperses pressure from the spring unit across the mattress. In practice, this helps the mattress keep its feel for longer.
- Durable case. A soft but hard-wearing outer case designed to keep the mattress comfortable for years.

- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who fidgets or turns often is simply too far away to wake you.
- Distance plus independent springs: The pocket springs respond individually to movement, and at this width most of your partner's shifting happens well outside your half anyway.
- Room for night-time visitors: A child padding in at 3am, or a dog who treats the bed as routine, fits without anyone ending up clinging to an edge.
- Airflow across a bigger surface: The foam-free Airloft build breathes by design, and with 180cm of width two warm sleepers are far less likely to share each other's heat.
- The right scale for a large room: In a big master or a period bedroom, a UK super king fills the space properly where a UK king can look a little lost.
This size suits you if...
You share the bed every night and want the most space any standard UK size offers, your partner is genuinely restless and you'd rather solve it with distance than hope a comfort layer copes, or your household includes children or pets who join you more nights than not. Your bedroom should comfortably clear our suggested 3m x 2.9m minimum, with around 3.5m x 3.2m feeling right.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king, or the bed would dominate the room. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is a super king too big for a couple?
Not if your room can take it. Two people get 90cm each, roughly a single bed's worth of space per person, and on this mattress that pairs well with pocket springs that respond independently to movement. If children or pets regularly join you, the extra width stops anyone being squeezed out.
What room size do I need for the Comfort Breathe Plus 1600 super king?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels right, leaving space to walk round the bed and open wardrobe doors. This is our guidance rather than Silentnight's. Measure door swing and any landing turns too, as those often decide the matter before the room does.
Does the super king Comfort Breathe Plus 1600 help with a restless partner?
It's the strongest size for this. The 600 Mirapocket springs move independently, so a turning partner disturbs less of the surface, and at 180cm wide most of their movement happens nowhere near you. If disturbance is your main complaint about your current bed, width solves more of it than any comfort layer.
What bedding fits a Silentnight super king mattress?
Super king fitted sheets, made for 180 x 200cm, and we'd suggest a 260 x 220cm duvet so the overhang covers both sleepers properly. Bedding at this size does cost more than king equivalents, and there's less choice on the high street, so factor that in before you commit.
Is the super king worth it over the king for this mattress?
The UK super king is 30cm wider than the UK king and the same length, so the entire gain goes into sleeping width. If you share with a partner who moves a lot, or with children or a dog, that 30cm is the difference. Sleeping alone, or in a tighter room, the UK king does the job.
