Layer Details
Central pocket springs
A core of 2000 pocket springs, each housed in its own cloth sleeve. This gives the mattress its firm, supportive base, with each spring working on its own rather than moving as one.
Pocket spring tablet comfort layers
Three layers of 1500 pocket spring tablets sit on either side of the core. Because both sides are built the same way, you can flip and rotate the mattress to help it wear evenly.

Key benefits
- Proper space for two: At 75cm each for two people sharing, both of you get room to stretch out rather than negotiating for the middle.
- Less partner disturbance: Pocket springs respond independently, which means a partner getting up hours before you is less likely to shake you awake, and the extra width helps too.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, a real difference for anyone approaching six foot.
- A firm feel that suits sharing: A firm mattress at this width gives an even, stable surface across the whole bed, so neither of you rolls towards the other.
- Easier to compare at this size: The prices shown on this page are updated as retailers change them, so check the live table before you commit.
This size suits you if...
You share the bed every night and a double has started to feel tight, especially if one of you keeps different hours or a dog has claimed a corner as routine. It also suits you if either sleeper is tall, since the 200cm length gives welcome extra room at the feet. Your bedroom should offer at least 2.7m x 2.9m, which is our suggestion rather than Millbrook's.
Consider another size if...
Your room falls short of the 2.7m x 2.9m we suggest, or you sleep alone and would rather spend less on width you won't use. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the UK king Millbrook Wool Sublime a good size for couples?
For most couples, yes. It gives 75cm each for two people sharing, which is 7.5cm more per person than the UK double. Combined with pocket springs that move independently, that extra width means a restless partner or one who gets up early disturbs you less. It costs more than a double, but the difference in space is felt every night.
Is a UK king long enough for someone over six foot?
At 200cm (6ft 6in), the UK king gives most tall sleepers comfortable clearance, and it's 10cm longer than the UK double. If one of you is well over six foot, length rather than width may be the real reason to size up. The UK super king is the same length, so going bigger again only buys width, not extra legroom.
Will a king size fit in a smaller master bedroom?
We suggest at least 2.7m x 2.9m for a UK king, and that's our guidance rather than Millbrook's. New build master bedrooms can feel smaller than the floorplan suggests once wardrobes go in, so measure the usable space, allowing room to walk round both sides, before committing to a 150 x 200cm mattress.
Should I choose the UK king or UK super king in this mattress?
The UK super king is 30cm wider, giving 90cm each for two sharing against the UK king's 75cm, though both are the same length. It needs a bigger room too: we suggest at least 3m x 2.9m for the UK super king. If your room comfortably clears that and you value maximum personal space, size up; otherwise the UK king is the more practical choice.
Where can I buy the Millbrook Wool Sublime in a UK king?
Compare the retailers listed on this page, where prices are updated as retailers change them. This is a premium mattress, so it pays to check the live table rather than assume the first price you see is current. Millbrook doesn't publish detailed construction or depth figures for this model, so confirm any specifics with the retailer before you buy.
