Layer Details
Comfort Layer
A layer of 100% Hampshire fleece wool, locally sourced from Hampshire. Wool is naturally breathable and temperature-regulating, so it helps keep you comfortable through the seasons.
Comfort Layer
Natural English cotton fibres that regulate body temperature and wick away moisture. This means less of that clammy feeling on warmer nights.
Support System
1000 individually hand-nested pocket springs, each encased in its own cloth pocket. Because every spring moves independently, you get tailor-made support and less disturbance from a partner shifting position.

Key benefits
- 90cm each, every night: Two sharers each get 90cm of width, which means a partner who turns constantly all night becomes far easier to sleep through.
- Independent springs across a wide surface: The 1000 hand-nested pocket springs move separately, so movement on one side of this 180cm width barely carries across to yours.
- Space for the whole household: Children padding in at 3am, or a dog who treats your bed as routine, still leave everyone with a workable share at this size.
- Wool that copes with extra bodies: Hampshire fleece wool and English cotton regulate temperature, useful when three warm sleepers share one surface on a summer night.
- Firm support edge to edge: The firm feel holds up when sleepers spread across the full width, rather than everyone rolling towards a soft middle.
This size suits you if...
You share every night and a UK king still feels like a compromise, you have a restless partner and want distance rather than another comfort layer to solve it, or children and pets regularly join you and you'd like everyone to keep their own patch. Your bedroom should measure at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or you'd struggle to turn a mattress this large regularly. We'd recommend the UK king instead: 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on the Millbrook Wool Ortho 1000 super king?
90cm each for two people sharing, the same width per person as a UK single. Combined with the 1000 individually pocketed springs, which respond to each body separately, that means a fidgeting partner is both further away and less felt through the mattress itself.
Is the super king Millbrook Wool Ortho 1000 difficult to turn?
It's the hardest size of this mattress to manage. The mattress is double-sided and needs regular turning to even out wear, and at 180 x 200cm that's realistically a two-person job. The turning handles help, but plan on doing it together rather than alone.
What room size do I need for the Millbrook Wool Ortho 1000 in a super king?
We suggest at least 3m x 2.9m, and that's our guidance rather than Millbrook's. Around 3.5m x 3.2m feels right, leaving space for bedside tables on both sides and doors that open fully. In a smaller master, a UK super king can dominate the room.
Should I choose the UK king or the UK super king in this mattress?
The UK super king is 30cm wider than the UK king, and both are the same length, so you're paying purely for width. The UK king gives 75cm each for two sharing, while the UK super king gives 15cm more each. If children or pets join you regularly, that extra width is where it shows.
Is the Millbrook Wool Ortho 1000 super king good for restless partners?
It's a strong choice for exactly that. Distance does more than any comfort layer, and 90cm each is as much separation as standard UK sizes offer. Each of the 1000 pocket springs is encased in its own cloth pocket, so their movement is absorbed rather than sent rippling across to your side.
