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.

- 75cm each for two sharing: The UK king gives 75cm each, which means both of you can settle into your own space rather than negotiating the middle.
- Pocket springs limit partner disturbance: Individually responsive springs compress only where weight sits, so an early alarm on one side registers less on the other.
- 200cm of length for taller sleepers: The UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping with their feet at the edge.
- Zoned firm support across the full width: Seven ergonomic zones run across all 150cm, so both sleepers get firmer support at the hips whatever side they take.
- Wool keeps a shared bed cooler: Two people generate more heat than one, and the Hampshire wool comfort layer helps regulate temperature across the wider surface.
This size suits you if...
You share the bed every night and a UK double has started to feel tight, one of you gets up hours before the other and you want that movement kept to their side, or someone in the bed is approaching six foot and needs the 200cm length as much as the width.
Consider another size if...
Your bedroom is under our suggested minimum of 2.7m x 2.9m for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives 67.5cm each for two sharing.

What are the dimensions of the Millbrook Regent Wool Ortho in a UK king?
The UK king measures 150 x 200cm, which is 5ft x 6ft 6in. That gives two people sharing 75cm each, and the 200cm length adds welcome room for taller sleepers. At 25cm deep, standard UK king fitted sheets will fit without any struggle.
Is a UK king Millbrook Regent Wool Ortho good for couples on different schedules?
Yes. The 1000 pocket springs respond individually, so movement on one side transfers less across the bed, and 75cm each means you're rarely in contact to begin with. If one of you leaves for work hours before the other, this size and construction together make that exit much quieter.
What room size do I need for a king size Millbrook Regent Wool Ortho?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be smaller than they look on a plan, so measure with furniture in place before committing to the UK king.
Is the king size big enough if one of us is over six foot?
At 200cm long, the UK king suits sleepers approaching or just over six foot; it's 10cm longer than the UK double, and the UK super king is the same length. If length is your main concern rather than width, the UK king already gives you the maximum this range offers.
