Layer Details
- Wool comfort layer. Soft, springy British wool sits at the surface and moulds around your body shape. It's naturally breathable yet insulating, which means it helps regulate temperature through the seasons.
- Cotton, hemp and flax blend. Further layers of cotton and wool blended with hemp and flax fibres improve airflow within the mattress. These fibres also wick away moisture, useful if you tend to sleep warm.
- Mini pocket springs. A layer of 14000 mini springs contours to your body for personalised comfort. Because each spring moves independently, there's room for air to circulate too.
- Cortec Quad Revolution pocket springs. An award-winning layer of 1000 springs with a dual design, each in its own pocket and secured into groups of four. They're highly flexible, adjusting to your movement and weight through the night.
- Posturfil springs. A base layer of 1500 Posturfil springs, flexible and adaptable. They sense movement to keep support consistent as you shift position.

- 90cm each, every night: Two people sharing get 90cm each, which means neither of you compromises on sleeping position or ends up clinging to an edge.
- Distance beats disturbance: The Cortec Quad Revolution springs flex with individual movement, and at this width a fidgety partner is simply too far away to wake you anyway.
- Room for the whole household: When a child pads in at 3am or the dog claims the foot of the bed, a UK super king still leaves both adults a proper share.
- Cool across the full width: Wool, hemp and flax breathe better than synthetic fillings, which matters when two warm bodies share a bed through the night.
- Contouring at scale: The mini spring comfort layers adapt to each sleeper's shape independently, so a lighter partner and a heavier one each get their own level of give.
This size suits you if...
You share the bed every night and want the maximum space a standard UK size offers, your partner shifts around and you'd rather have distance than earplugs, or children and pets regularly join you and everyone still needs their own patch. Your room should comfortably clear the 3m x 2.9m minimum we suggest, ideally with more.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or the bed would leave little walking space. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

Is the Palladium 16500 UK super king good for a restless partner?
Yes, and largely because of the width. With 90cm each for two people sharing, most movement happens too far away to disturb you. The pocket spring construction helps too: each spring moves independently, and the Cortec Quad Revolution layer adjusts to movement and weight, so shifting on one side transfers less across the bed.
How much bigger is the UK super king than the UK king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. That extra width is the difference between sharing comfortably and negotiating space, particularly if children or pets join you. The UK king needs a room of at least 2.7m x 2.9m; for the UK super king we suggest at least 3m x 2.9m.
Is a UK super king worth it for a family that shares the bed?
If a child wanders in most nights or a large dog treats the bed as its own, this is the size where everyone still gets a reasonable share. At 6ft x 6ft 6in, an extra small body no longer pushes an adult to the edge. The Palladium 16500's soft to medium surface is also forgiving for lighter sleepers.
Will the Palladium 16500 sleep hot in a super king shared by two?
It shouldn't. The build avoids foam almost entirely, using British wool, cotton, hemp and flax, and these fibres breathe and wick moisture rather than trapping heat. Two people sharing generate more warmth than one, so the natural fillings and the airflow between the mini pocket springs matter more at this size than in a single.
