Layer Details
- Cover. A sumptuously soft natural cover, designed for enhanced breathability. In practice, that means air can move through the sleep surface rather than trapping heat against you.
- Wool. Fully traceable Black Country wool that regulates temperature. Wool wicks moisture and buffers heat, so you should feel more even in temperature through the night.
- Fibres. Recyclable, air-blown fibres that give the feel of a million micro springs. This creates a cushioned, responsive surface layer above the main spring unit.
- Pocket Springs. Individually encased pocket springs that adapt to your body's movements to minimise disturbance to your partner, while supporting your back and hips. Each spring moves on its own, so one person turning over is less likely to jolt the other.

- Distance plus isolation: The pocket springs already limit movement transfer, and at 90cm each for two people sharing, your partner's fidgeting happens a long way from you anyway.
- Space for night-time visitors: When a child pads in at 3am, a 6ft-wide surface absorbs them without anyone ending up clinging to an edge.
- Room for the dog too: If a large dog treats your bed as its own, the UK super king leaves enough width that the humans still sleep properly.
- Flippable at full size: The Elsham is double-sided, so this large surface can be turned regularly to even out wear, although the 180 x 200cm size makes flipping a two-person job.
- Wool that copes with a crowd: More bodies means more heat, and the traceable Black Country wool wicks moisture, which helps the bed stay temperate when it's shared by three.
This size suits you if...
You share every night and want the most sleeping space a standard UK size offers, your partner is restless enough that a UK king still feels close, or children and pets regularly join you and you'd rather plan for it than fight it. A larger master bedroom helps: we suggest at least 3m x 2.9m for this size, with more feeling comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is the super king Elsham too big for a normal bedroom?
It might be. At 180 x 200cm, or 6ft x 6ft 6in, we suggest a room of at least 3m x 2.9m, and many UK bedrooms fall short of that. Measure with wardrobe doors and drawers open. If the numbers are tight, the UK king is 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.
Is a UK super king Elsham worth it for a restless partner?
Yes, if the room allows. The Elsham's individually encased pocket springs already limit how much movement travels across the bed, and 90cm each for two people sharing adds physical distance on top. Between the two, one person turning over repeatedly is far less likely to register on the other side.
Can the Elsham super king fit up a narrow staircase?
This is the size where stairs bite. A 180cm-wide mattress is awkward on tight landing turns and through standard doorways, and pocket sprung mattresses only flex so far. Measure your stairwell, landing and bedroom door before ordering, and check the retailer's delivery access policy on the pages linked here.
How hard is it to flip a super king Elsham?
The Elsham is double-sided and benefits from regular flipping, but at 180 x 200cm this is realistically a two-person job. Clear space around the bed first and turn it in stages. If you live alone or struggle with lifting, the UK king is 30cm narrower and slightly easier to handle.
Does the Elsham super king make sense for co-sleeping with children?
It's one of the better cases for this size. With a 6ft width, a wandering child or a large dog can join without pushing either adult to the edge, and the wool layer helps manage the extra body heat. Factor in super king bedding costs, which run higher than smaller sizes.
