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.

- Real room for two: At 75cm each for two people sharing, that's 7.5cm more per person than the UK double, which means fewer accidental elbows through the night.
- Less disturbance across a wider bed: The 1000 hand-nested pocket springs respond individually, so on a 150cm-wide surface a partner getting up early is far less likely to wake you.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, welcome relief if one of you is approaching six foot.
- Firm support that holds at the edges of sharing: A firm pocket spring build suits back sleepers and heavier builds, and the extra width means each of you gets that support without crowding.
- Wool comfort scaled up: Hampshire fleece wool and English cotton breathe rather than trap heat, useful when two bodies are warming one bed all night.
This size suits you if...
You share the bed every night and have outgrown a double, one of you is tall enough that 190cm beds leave feet at the edge, or your different schedules mean one of you climbs out hours before the other and you want the movement to go unnoticed. Your room allows at least 2.7m x 2.9m, which is our suggested minimum for a UK king.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m of room.

Is the Millbrook Wool Ortho 1000 in a UK king good for couples?
Yes, provided you both get on with a firm feel. The UK king gives 75cm each for two people sharing, and the 1000 individually pocketed springs mean one person shifting or getting up early transmits little movement across the bed. Lightweight side sleepers may still find the firmness hard on shoulders and hips, whatever the size.
How big is the Millbrook Wool Ortho 1000 UK king?
It measures 150 x 200cm, which is 5ft x 6ft 6in. That makes it 15cm wider and 10cm longer than the UK double, and 30cm narrower than the UK super king, which shares the same 200cm length.
Will a UK king Millbrook Wool Ortho 1000 fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round the bed and open drawers. Smaller new build master bedrooms can shrink quickly once wardrobes go in, so measure the usable floor rather than the room on the plan before committing.
Is the UK king long enough for someone over six foot?
The 200cm length helps considerably. A UK double is only 190cm long, so anyone approaching six foot tends to find their feet at the edge. The UK king adds 10cm, and because this mattress is firm, taller sleepers won't sink into a hammock shape that shortens the bed further.
