Layer Details
Knitted cover
A soft knitted finish that adds cosiness and warmth. Knitted covers enhance airflow, so the surface should feel comfortable without trapping too much heat.
Pillow top
An extra layer of plush wool and cotton fillings, tufted to hold them in place. It gives the surface a softer, more cushioned feel without changing the medium rating.
Mini pocket springs
Small, individually cased springs that add comfort and reduce motion transfer. You get a gentler feel and less disturbance from a restless partner.
Pocket springs
Individually cased springs in cloth pockets that adapt to your movement. They spread support to each part of your body as you shift position.

Key benefits
- More room each night: At 75cm per person, you get 7.5cm more space each than on a UK double, which means less drifting into each other's half by morning.
- Quieter when one of you moves: A layer of mini pocket springs reduces motion transfer, and the extra width of a UK king puts a little more distance between you and a restless partner.
- Length for taller sleepers: The UK king is 200cm long, 10cm more than a UK double, which helps anyone near 6ft lie straight without their feet hanging over the end.
- Cushioning across a wider surface: The tufted wool and cotton pillow top runs the full 150cm width, so both sides get the same cushioned medium feel over the springs.
- Fits more bedrooms than a super king: We suggest a room of at least 2.7m x 2.9m for a UK king, compared with 3m x 2.9m for the UK super king.
This size suits you if...
You share a bed and wake up when your partner turns over or gets up hours before you, one of you is around six foot and tired of cold feet poking out, or you've outgrown a UK double but your room can't take anything wider.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once the wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Millbrook Wool Luxury 1500 Pocket Pillowtop UK king big enough for two?
For most couples, yes. A UK king gives each of you 75cm, which is 7.5cm more than a UK double. The mini pocket springs reduce motion transfer too. That helps on schedules where one partner gets up much earlier, although very light sleepers may still feel some movement.
Will a UK king pillowtop mattress suit a partner over six foot?
It should help. At 200cm, the UK king is 10cm longer than a UK double, so someone approaching 6ft has room to stretch out. Length is often the real reason tall sleepers size up, and the UK king and UK super king are the same length.
What size bedroom do I need for a UK king mattress?
We suggest at least 2.7m x 2.9m, and around 3.2m x 3.2m if you want bedside tables and easy walking space on both sides. New build master bedrooms can feel tighter than the floor plan suggests, so measure with the furniture in place.
Should I get the Millbrook Wool Luxury 1500 Pocket Pillowtop in a UK king or a UK super king?
The UK super king gives 90cm each, which is 15cm more per person than the UK king. It also needs a room of at least 3m x 2.9m. If you regularly share the bed with a dog or a child, the UK super king is the better choice. Otherwise, the UK king suits most couples.
What bedding fits a UK king Millbrook pillowtop?
You need UK king sheets and a 230 x 220cm king duvet. The mattress is 30cm deep, so check that your fitted sheets are made for a deep mattress before buying. Measure your stairs as well, then compare the retailers listed on this page.
