Layer Details
Micro tablet springs
The top layer is made up of 3000 Confonomic micro tablet springs, which sit above the main spring system. This means a more responsive, finely sprung surface over the support beneath.
Pocket spring base
The base layer has 1000 standard pocket springs, forming the lower tier of the 2-tier ErgoZone7 system. It provides the main support, arranged in seven zones to suit different parts of your body.

Key benefits
- 75cm each for two sharing: Two people sharing get 75cm each, enough to turn over or stretch out without immediately meeting an elbow.
- Pocket springs help with different schedules: Pocket springs move independently, which means one partner slipping out for an early start is less likely to disturb the other, and the UK king's width adds distance too.
- Extra length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, a genuine relief for anyone approaching six foot whose feet currently reach the end.
- A medium firm pillowtop with room to use it: The pillowtop finish adds a softer surface layer over the medium firm springs, and the wider footprint means you can actually spread out on it.
- Room for the dog without a fight: If a pet on the bed is part of the routine, the UK king absorbs that lost corner far better than a UK double does.
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 sleeps on a different schedule to the other. It also suits couples where one partner is over six foot, since the 200cm length gives feet somewhere to go, or households where a pet claims a share of the mattress most nights.
Consider another size if...
Your bedroom is tighter than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, allowing at least 2.6m x 2.8m for it.

FAQ's
How much space does each person get on the Millbrook Allure UK king?
Two people sharing a UK king get 75cm each. On the UK double it's 67.5cm each, so the UK king gives 7.5cm more per person. That difference sounds small on paper but you feel it every night, particularly if one of you shifts position a lot or you're sharing with a pillow fort during pregnancy.
Is the UK king Millbrook Allure good for couples on different schedules?
It's a sensible pairing. The Pocket 4000's springs are individually pocketed, so they compress independently rather than transferring movement across the bed, and the 150cm width puts more distance between you. If one of you gets up hours before the other, both factors reduce the chance of waking your partner.
Will a UK king Millbrook Allure fit in a new build master bedroom?
Often, but measure first. We suggest a room of at least 2.7m x 2.9m for a UK king, and new build masters can be smaller than they look once fitted wardrobes and bedside tables are in. If your room falls short, the UK double needs at least 2.6m x 2.8m and would suit you better.
Is the UK king long enough for someone over six foot?
Yes, and length is often the real reason taller sleepers upgrade. The UK king is 200cm long, which is 10cm longer than the UK double, so feet stop hanging off the end. If you're tall and the width already feels fine, this extra length may be the change you actually notice.
Should I choose the Millbrook Allure in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king, and both are the same length. Sharing a UK super king gives 90cm each against the UK king's 75cm. The trade is space in the room: we suggest at least 3m x 2.9m for the UK super king, so smaller bedrooms favour the UK king.
