Layer Details
Pillowtop
A sumptuous tufted pillowtop with layers of British wool. This is what gives the mattress its soft, sink-in first impression.
Silk, wool, cashmere and alpaca layer
An additional layer of silk, wool, cashmere and alpaca, which means the comfort layers breathe well and regulate temperature rather than trapping heat.
Sustainable fresh fibres
British wool layered with sustainable fresh fibres. This adds cushioning depth between the natural fillings and the springs.
Pocket springs
2000 zoned pocket springs with an additional 1000 mini springs. The zoning means firmer support under heavier areas like your hips, while the mini springs fine-tune the surface response.

Key benefits
- Room to spread without touching: At 75cm each for two people sharing, you can shift position on that plush pillowtop without landing on your partner.
- Pocket springs limit partner disturbance: The 2000 zoned pocket springs move independently, which means an early alarm on one side transfers less across the wider surface.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK Double, a genuine relief for anyone nudging six foot.
- Soft feel that stays breathable at scale: Wool, silk, cashmere and alpaca fillings breathe well, so two bodies sharing a plush surface won't turn it clammy.
- A wide choice of bases and bedding: UK king is one of the most common sizes, so frames, sheets and duvets are easy to find.
This size suits you if...
You share the bed every night and a double has started to feel tight, especially if you and your partner keep different hours and want an early exit to go unnoticed. It also suits taller sleepers who find 190cm mattresses leave their feet at the edge, and couples who share the bed with a dog that claims more than its share.
Consider another size if...
Your bedroom falls below our suggested minimum of 2.7m x 2.9m for a UK king. In that case we'd recommend the UK double instead, which needs around 2.6m x 2.8m and still suits two lighter-weight side sleepers on this soft build.

FAQ's
Is a UK king big enough for a couple on the Milldale 3000?
Yes, comfortably for most. You get 75cm each for two people sharing, and because this is a soft mattress with a deep pillowtop, that extra width matters: it lets each of you settle into your own patch of cushioning rather than rolling towards the middle together.
Will I feel my partner getting up on the king size Milldale 3000?
Less than on a smaller mattress. The 2000 zoned pocket springs plus 1000 mini springs respond individually, so movement stays fairly local, and the UK king's width puts more distance between you. If one of you leaves for work hours before the other, that combination makes a noticeable difference.
What room size do I need for the Milldale 3000 in a UK king?
We suggest at least 2.7m x 2.9m, with something nearer 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables go in. New build master bedrooms can be tighter than they first appear, so measure with furniture in mind before committing to a 150 x 200cm mattress.
Is the UK king long enough for someone over six foot?
At 200cm, it should be. That's 10cm longer than the UK Double, which is often the detail taller sleepers actually notice, since it stops feet hanging off the end. If length rather than width is your problem, the UK king solves it without the room demands of a UK super king.
Should I get the Milldale 3000 in a UK king or a UK super king?
The UK king is 30cm narrower than the UK Super King, and the two are the same length. If you regularly share with children or a dog, that extra width earns consideration, but we suggest at least 3m x 2.9m for the UK Super King, so check your room can take it first.
