Layer Details
Cover
A soft-touch cotton-viscose cover infused with M-Pure, a 100% plant-based, sustainable treatment. This gives a breathable sleeping surface rather than a synthetic one.
Comfort fillings
Layers of 100% fleece wool sourced from Hampshire, blended with layers of cotton and hand-tufted. Tufting anchors the fillings in place, which means less shifting and settling over the years.
Support system
1000 individual hand-nested pocket springs, each encased in cloth pockets. Because each spring moves on its own, the mattress responds to your shape and limits motion transfer between partners.

Key benefits
- 75cm each for two sharing: Each of you gets 75cm of width, which means you can shift position through the night without ending up shoulder to shoulder.
- Pocket springs plus space equals quieter nights: The 1000 hand-nested springs move independently, and at this width your partner's early alarm or late return is far less likely to wake you.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which means anyone approaching 6ft finally gets their feet on the mattress.
- Wool that copes with two body heats: Two sleepers generate more warmth than one, and the Hampshire wool and cotton fillings breathe better than synthetic foam, so the bed runs cooler.
- Medium firm support across the full width: Hand-tufting anchors the natural fillings edge to edge, which means the surface stays even rather than dipping where each of you always sleeps.
This size suits you if...
You share the bed every night and the UK double has started to feel cramped, especially if one of you keeps different hours and you'd rather not feel every movement. Or one of you is tall enough that a standard-length mattress leaves feet hanging off the end, since the UK king adds length as well as width. It also suits couples whose dog treats the bed as its own.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives two sharers 67.5cm each.

FAQ's
Is the Millbrook Wool Luxury 1000 in a UK king big enough for a couple?
Yes, comfortably for most. The UK king gives 75cm of width each for two people sharing, 7.5cm more per person than the UK double. Combined with the 1000 independent pocket springs, that space noticeably reduces how much you feel a partner turning over or getting up early.
What room size do I need for the Millbrook Wool Luxury 1000 in a UK king?
We suggest a room of at least 2.7m x 2.9m, which leaves walking space around the bed and room to open drawers. New build master bedrooms can be tighter than they look once wardrobes go in, so measure the usable floor rather than the full room.
Is a UK king long enough if my partner is over six foot?
Usually, yes. The UK king is 200cm long, 6ft 6in, and 10cm longer than the UK double. For most people over six foot that extra length is the real upgrade, since it stops feet hanging off the end without demanding a bigger room than a super king would.
Should I pick this mattress in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king and the same length, giving sharers 90cm each rather than 75cm. It suits couples with a large room, since we suggest at least 3m x 2.9m for it. If your room is closer to 2.7m x 2.9m, the UK king is the sensible choice.
