Layer Details
- Pillowtop. A sumptuous tufted pillowtop with layers of British wool. This is what gives the mattress its soft, sink-in first impression.
- Silk, wool, cashmere and alpaca layer. An additional layer of silk, wool, cashmere and alpaca, which means the comfort layers breathe well and regulate temperature rather than trapping heat.
- Sustainable fresh fibres. British wool layered with sustainable fresh fibres. This adds cushioning depth between the natural fillings and the springs.
- Pocket springs. 2000 zoned pocket springs with an additional 1000 mini springs. The zoning means firmer support under heavier areas like your hips, while the mini springs fine-tune the surface response.

- 90cm each for two sharers: With 90cm each for two people sharing, one of you turning over on a soft pillowtop is much less likely to wake the other.
- Space absorbs a soft surface's movement: Soft mattresses transmit more of a partner's shifting than firm ones, so the distance a UK super king provides matters more here than on a firmer model.
- Room for the whole household: If children or a large dog treat your bed as theirs, this size means everyone keeps a genuine share rather than clinging to an edge.
- Breathable fillings across a big surface: The wool, silk, cashmere and alpaca layers stay cool, useful when three bodies share one mattress on a warm night.
- Fills a large master properly: In a period property or big new build master, a UK king can look undersized; the UK super king suits the proportions of the room.
This size suits you if...
You share the bed every night and one of you is a genuinely restless sleeper, since 90cm each for two people sharing gives a soft mattress the distance it needs to keep movement from travelling. It also suits you if children or pets regularly join you before morning, or if your bedroom is large enough that a smaller bed would feel lost in it. Allow at least 3m x 2.9m of floor space.
Consider another size if...
Your room falls short of the 3m x 2.9m we suggest, or you sleep alone. The UK king would suit you better: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

Is a super king too big for my bedroom?
We suggest at least 3m x 2.9m of floor space for a UK super king, and that's a minimum rather than a comfortable fit. Measure with wardrobe doors and door swing in mind, and check any landing turns on the way up. If the room is tight, the UK king needs at least 2.7m x 2.9m.
Is the Milldale 3000 super king good for restless couples?
It's one of the better cases for sizing up. The Softer build has a plush pillowtop, and soft surfaces pass on more movement than firm ones, so the 90cm each for two people sharing that a UK super king provides does more to protect your sleep than any comfort layer could.
Can children share a super king with us?
This is where the size makes sense. A child wandering in at 3am can settle between you without pushing either adult to the edge, and the breathable wool and silk fillings help when three warm bodies share one surface. The soft feel is gentle on smaller frames too.
Should I get the super king or the king in the Milldale 3000?
The UK super king is 30cm wider than the UK king and the same length. If you share with a restless partner, children or pets, that extra width is the point of this size. Sleeping alone, or in a room under 3m x 2.9m, the UK king is the sensible choice.
What bedding will I need for a super king Milldale 3000?
Super king sheets and a 260 x 220cm duvet. Bedding at this size costs noticeably more than king equivalents and fewer ranges stock it, so it's a running cost to factor in before you commit, alongside a bed frame built for a 180 x 200cm mattress.
