Key benefits

Key Benefits of the Millbrook Wool Sublime Medium Pocket 8000 King Size Mattress

  • Proper personal space for two: At 75cm each for two sharing, you get room to change position without negotiating with your partner first.
  • Wider than a double where it counts: The UK king is 15cm wider than the UK double, giving each of you 7.5cm more, which you feel every night rather than just on paper.
  • Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, so anyone approaching six foot stops waking with their feet at the edge.
  • Pocket springs reduce partner disturbance: The Pocket 8000's individual springs respond locally, which means an early riser can get up with less ripple reaching the other side.
  • Room for a nighttime visitor: If a dog treats your bed as its own, the extra width absorbs that habit without either of you losing a fair share.

Who should buy the Millbrook Wool Sublime Medium Pocket 8000 King Size Mattress?

This size suits you if...

You share the bed every night and a double has started to feel like a compromise, one of you gets up hours before the other and you want the pocket springs to have space to do their job, or one of you is nudging six foot and needs the 200cm length more than anything else.

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 and still offers the same pocket sprung feel.

FAQ's

Frequently Asked Questions About the UK King

How much space do two people get on the UK king Millbrook Wool Sublime?

The UK king measures 150 x 200cm, which gives 75cm each for two people sharing. That's 7.5cm more per person than the UK double offers, enough that you can each settle into your own side without drifting into the other's space.

Will the UK king Millbrook Wool Sublime fit in my bedroom?

We suggest a room of at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on the plans, so measure with furniture in place before committing.

Is the Millbrook Wool Sublime UK king long enough for someone over six foot?

The UK king is 200cm long, 10cm more than the UK double, which is usually the difference between feet hanging over the edge and sleeping fully stretched out. If length is your main concern, the UK king solves it; sizing up further to the UK super king adds width only, as both sizes share the same 200cm length.

Should I get the Millbrook Wool Sublime in a UK king or a UK super king?

The UK super king is 30cm wider, giving 90cm each for two sharing rather than the UK king's 75cm. It also demands more room: we suggest at least 3m x 2.9m for it. If your bedroom can take it and you both want maximum space, size up; for most couples the UK king is generous enough.

Where can I buy this mattress in a UK king?
