Layer Details
Cover
A fine English cotton cover, spun and crafted in the North West of England. Cotton is soft against bedding and breathable, which helps keep the sleep surface fresh.
Comfort Layer
Sustainably sourced Hampshire wool provides the cushioning here, and it's known for durability and elasticity. That means a comfort layer that should keep its feel over time rather than flattening quickly.
Support System
A 7-zone ergonomic pocket spring system with 1000 individually responsive springs. Each zone is tailored to a specific area of the body, so you get softer comfort at the shoulders and firmer support at the hips and lower back.

Key benefits
- Maximum space for two: At 90cm each for two people sharing, you can both stretch out fully without meeting in the middle.
- Distance beats disturbance: The 1000 individually responsive pocket springs limit motion transfer, and the sheer width of a UK super king does the rest when one of you fidgets.
- Room for the whole household: When children or a large dog treat your bed as theirs, a UK super king means everyone still gets a fair share of firm support.
- Seven zones across a wide surface: The 7-zone spring system supports hips and lower back more firmly than shoulders, which means each sleeper gets that tailored feel on their own side.
- Wool that breathes: Hampshire wool in the comfort layer regulates temperature naturally, which matters when three bodies and a duvet share one mattress.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and distance matters more to you than any comfort layer, or children and pets regularly join you and a UK king has started to feel crowded. Your bedroom should comfortably clear our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room is under our suggested 3m x 2.9m minimum, or you mostly sleep alone. We'd recommend the UK king instead: it's 30cm narrower, the same length, still gives 75cm each for two sharing, and we suggest at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on the UK super king Millbrook Regent Wool Ortho?
Two people sharing get 90cm each, the most of any standard UK size. That's enough for each of you to sleep entirely on your own side, with the 7-zone pocket spring system supporting hips and shoulders independently across the full 180cm width.
Is the UK super king much bigger than the UK king for this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. The UK king gives 75cm each for two sharing, so the UK super king gives 15cm more each. That extra width is the difference between tolerating a restless partner and barely noticing them.
Is the Millbrook Regent Wool Ortho in a UK super king a good choice for sharing with children or pets?
It's well suited to it. The firm feel and 180cm width mean a child climbing in at night, or a large dog with established habits, doesn't push either adult to the edge. The breathable wool comfort layer also helps when extra bodies raise the temperature under the duvet.
Will the super king Millbrook Regent Wool Ortho get up the stairs?
This mattress arrives flat rather than rolled and boxed, and at 180 x 200cm it's a big, rigid item to manoeuvre. Before ordering, check your door swings, landing turns and stairwell width carefully, as awkward access is the most common snag at this size.
Does a super king reduce partner disturbance on this mattress?
Yes, in two ways. The 1000 pocket springs respond individually, so movement on one side transfers less to the other, and 90cm each of width puts real distance between you. For a genuinely restless partner, that combination works better than any single comfort layer would.
