Layer Details
- Comfort Layer. Sustainably sourced Hampshire wool with fine cotton fibres woven through it, sitting directly beneath you. Wool insulates in winter and breathes in summer, which means a more stable temperature through the night.
- Support System. A core of 1000 steel pocket springs, each enclosed in its own fabric pocket. Because every spring compresses independently, the mattress follows your shape rather than tilting as one surface, which also helps limit partner disturbance.
- Border. Sets of butterfly springs shaped to reinforce the mattress edge, held together by a rod frame. In practice that means firmer edges, useful if you sit on the bed to dress or tend to sleep near the side.

- Distance from a restless partner: With 90cm each, most movement simply happens too far away to wake you, and the 1000 pocket springs compress independently, so what remains barely transmits.
- Space when the family joins you: When a child pads in at 3am, the full 6ft of width means everyone keeps a usable share rather than someone clinging to an edge.
- 15cm more each than a UK king: The UK king gives 75cm per person; this size adds 15cm each while staying the same 200cm length, so taller sleepers lose nothing.
- Usable right to the edges: Butterfly springs and a rod frame firm up the border, which matters more at this width because families and pets push people towards the sides.
- Natural fibres across a big surface: The Hampshire wool and cotton layer breathes well, which helps when three bodies, or a dog, are adding warmth under one duvet.
This size suits you if...
You share every night and want each sleeper to have their own undisturbed territory, your children or pets treat your bed as partly theirs, or your master bedroom is large enough that a UK king would look and feel undersized in it. It also suits couples where one partner is genuinely restless, since distance does more than any comfort layer can.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for this size, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

How big is the Millbrook Smooth Tech Luxury 1000 in a super king?
The UK super king measures 180 x 200cm, or 6ft x 6ft 6in. That's the largest of the five sizes this mattress comes in, and the widest size UK retailers stock as standard. Two people sharing get 90cm each, which is why it's the size we'd point restless couples towards.
Is the super king worth it over the king for this mattress?
If the room allows, usually yes. The UK super king is 30cm wider than the UK king and exactly the same length, taking each sharer from 75cm to 90cm. That extra 15cm per person is what turns a partner's fidgeting from a nightly irritation into background noise, especially with pocket springs isolating movement.
Will the Millbrook Smooth Tech Luxury 1000 super king fit my bedroom?
We suggest a room of at least 3m x 2.9m for a UK super king, which leaves enough clearance to walk round the bed and open drawers. Measure the door swing and any landing turns too: a 180cm-wide mattress is an awkward carry, so check the route upstairs before you order.
Is a super king good for sharing with children or pets?
It's the best mainstream size for it. At 180cm wide there's room for a child or a large dog without either adult being pushed to the edge, and the firmed-up border means the edge is still supportive when you do end up there. The independent pocket springs help small nighttime arrivals go unnoticed.
Is this a good size for a restless partner?
Yes, arguably the main reason to choose it. Space is the most effective cure for partner disturbance: at 90cm each, movement happens further from you. The 1000 pocket springs then reduce what little travels across, since each spring compresses on its own rather than tilting the whole surface.
