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
- Room to spread out as a couple: Each of you gets 90cm of width, which means you can sleep on your own side without brushing elbows or competing for the middle.
- Distance plus quieter springs: The mini pocket springs dampen movement, and the extra width puts real distance between you and a fidgety partner, which matters more than any comfort layer.
- Space for small visitors: If a child climbs in after a bad dream, the UK super king leaves enough width that nobody ends up clinging to the edge until morning.
- Suits a large dog that shares: A big dog stretched across the foot or the middle takes far less of your sleeping area on a 180cm wide mattress than on a UK king.
- In proportion with a big bedroom: In a high ceilinged period room or a generous master, a UK king can look a little lost, while the UK super king fills the space properly.
This size suits you if...
You share the bed every night with someone who tosses and turns, or your children and pets regularly end up joining you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or tight stairs make a 180cm wide mattress a struggle. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Millbrook Wool Luxury 1500 Pocket Pillowtop UK super king big enough for two adults and a child?
For occasional night visits, yes. Two adults get 90cm each, so a small child tucked in between still leaves both of you a usable share. If a child joins you most nights, the pillow top keeps the surface comfortable, although an older child will make even this width feel a little fuller.
What size room do I need for a UK super king mattress like this one?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once you add bedside tables on both sides. In a loft conversion, measure where the full ceiling height is first, because the slope often decides which wall the headboard can go against.
How much more space does the UK super king give than the UK king?
The UK super king is 30cm wider than the UK king and the same length. Shared between two people, that works out at 15cm more each. If your partner is restless, that extra width plus the motion damping of the mini pocket springs makes a noticeable difference to how often you wake.
Will a UK super king mattress fit through my door and up my stairs?
Measure before you buy. You're manoeuvring something 180cm wide and 30cm deep, so check the door swing into the bedroom and any tight turns on the landing. Old cottages and narrow terraced staircases are where a mattress this wide most often gets stuck.
What bedding fits the Millbrook Wool Luxury 1500 Pocket Pillowtop in a UK super king?
You'll need super king sheets and a 260 x 220cm duvet. With a 30cm depth and a pillow top, choose deep fitted sheets so the corners stay put rather than pinging off when you turn over.
