Layer Details
- Cover. A soft-touch cotton-viscose cover with embroidered detailing, which means the surface feels smooth rather than scratchy. It's treated with M-Pure, a plant-based fire-resistant finish, so fire safety is handled without chemical-heavy treatments.
- Comfort fillings. Blended layers of 100% Hampshire fleece wool, silk and cashgora fibres with English cotton sit beneath the cover. Hand-tufting holds these fillings in place, which means they're less likely to shift or bunch over time.
- Support system. A 5000 pocket spring system with ErgoZone 7 zoning uses thicker gauge wire and higher tension under your head, hips and feet, with softer zones at the shoulders and legs. In practice that means firmer support where your body is heaviest and more give where you need pressure relief.
- Edge support. A metal rod runs along the top and bottom of the spring unit's edge, held with butterfly clips. This stiffens the border, so you get less of that roll-off feeling near the sides and better long-term durability.

- Distance from a fidgety partner: At 90cm each for two people sharing, a partner who turns all night is far enough away that their movement rarely reaches you.
- Room for midnight visitors: When a child wanders in at 3am, a 180cm width means everyone keeps a fair share instead of one adult perching on the border.
- Soft feel, spread wide: The soft to medium comfort layers give a gentle, cushioned surface, and in a UK super king each sleeper gets their own uninterrupted stretch of it.
- Edge support matters more at this width: The metal rod edge stiffens the border, which means the outer inches of this wide mattress stay usable rather than feeling like a roll-off zone.
- Breathable for two warm bodies: Hampshire fleece wool, silk and cashgora handle heat better than synthetic foams, useful when two people, and sometimes a dog, share one surface.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, you sleep next to someone genuinely restless and have learned that distance works better than any comfort layer, or your household includes children or pets who treat your bed as partly theirs. A larger master bedroom or period property with a generous floor plan will carry this size comfortably.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for a UK super king, or you sleep alone. We'd recommend the UK king instead, which gives 75cm each for two sharing and needs at least 2.7m x 2.9m.

Will a super king Millbrook Wool Luxury 5000 fit in my bedroom?
The mattress itself is 180 x 200cm, or 6ft x 6ft 6in. We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling right, so you can open wardrobes and walk round the bed without shuffling sideways. In a loft conversion, check the slope leaves a wall long enough to take the full 180cm width.
Is the super king worth it over the UK king for this mattress?
The UK super king is 30cm wider than the UK king and the two are the same length, which works out at 15cm more width each for two people sharing. If your partner is restless, or children climb in regularly, that extra width does more for your sleep than any filling. If you sleep undisturbed already, the UK king is the sensible saving.
Is the Millbrook Wool Luxury 5000 super king difficult to get upstairs?
It can be. This is a hand-tufted natural mattress with a sprung edge, so it will not fold or squeeze the way a rolled foam mattress does, and at 180 x 200cm it is a genuinely awkward carry. Before ordering, measure your stairwell, any landing turns and the bedroom door swing. Millbrook doesn't publish a weight, so plan for two people at minimum.
Can two people rotate the super king version on their own?
With two of you, yes, though expect it to be a proper job rather than a quick flip of a corner. The hand-tufted natural construction is heavy, and the super king is the widest and heaviest size in the range. If you live alone or would struggle with regular rotation, a smaller size of this mattress is the kinder choice.
Who sells the Millbrook Wool Luxury 5000 in a super king?
Stock moves around, so the most reliable answer is the live comparison table on this page, which is updated as retailers change their prices and availability. Because the UK super king sits at the top of the size range, it is usually the most expensive option, which makes comparing the retailers listed here before you commit particularly worthwhile.
