Layer Details
- Wool. Soft, springy British wool moulds around your body shape, which means the surface adapts to you rather than pushing back. It's naturally breathable yet insulating, so it helps regulate temperature across the seasons.
- Cotton, Wool, Hemp and Flax blend. Additional layers of cotton and wool blended with hemp and flax fibres improve airflow within the mattress. They also wick away moisture, keeping the sleep surface drier and fresher.
- Mini Pocket Springs. A layer of 14000 mini springs contours to your body for personalised comfort. Because they're springs rather than foam, air can still move through the layer.
- Posturfil Springs. These 1500 Posturfil springs are highly flexible and adaptable, sensing movement as you shift position. In practice that means the mattress responds to you through the night rather than leaving you to settle into one spot.
- Cortec Quad Revolution Pocket Springs. The base layer uses 1000 award-winning Cortec Quad Revolution pocket springs, a dual design with mini springs placed inside regular springs. Each sits in an individual pocket, secured in groups of four, which means support stays localised to where your body needs it.

- 90cm each, every night: Two people sharing get 90cm each, which means a partner turning over happens at a distance rather than against your back.
- Movement stays on their side: Individually pocketed springs, secured in groups of four, keep support localised, so at this width a fidgety sleeper is doubly easy to ignore.
- Space for the whole household: When children appear at 3am or the dog treats the bed as routine, 180cm of width means everyone still gets a fair share.
- A gentle feel across a big surface: The soft to medium wool and cotton comfort layers cushion side sleepers wherever they end up on all that width.
- Cooler for two bodies: Wool, hemp and flax fillings breathe and wick moisture, which matters more when two people are warming the same mattress all night.
- Sized for larger rooms: At 6ft x 6ft 6in it fills a generous master properly, where a UK king can look slightly lost.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your sleep is regularly interrupted by a restless partner or children and pets joining you, or you have a large master bedroom where a smaller bed would look out of proportion. It helps if you both prefer a softer, side sleeper friendly feel, because that is what this mattress delivers.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or the bed only occasionally sleeps two. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs a room of at least 2.7m x 2.9m.

What room size do I need for a super king Palladium 16500?
We suggest a room of at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling comfortable once you add bedside tables on both sides and space to walk around. In anything smaller, the UK king needs at least 2.7m x 2.9m and gives up 30cm of width but no length.
Is the Palladium 16500 super king good for restless couples?
It's one of the better cases for this size. The pocket springs sit in individual pockets secured in groups of four, so movement stays localised rather than travelling across the bed, and 90cm each for two people sharing means most disturbance happens too far away to notice. Distance plus isolated springs is a strong combination.
How much bigger is a super king than a king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. That 30cm is the whole argument: it's the difference between 90cm each and noticeably less, which you'll feel most on nights when a child or pet joins you.
Will the Palladium 16500 fit in a loft conversion or period property?
Often yes, but measure first. In a loft room the slope usually decides which wall takes the bed, and you'll need clear height on both sides for getting in and out. Period properties can have tight landing turns and narrow door swings, so check the route upstairs before ordering a mattress this size.
What bedding does a super king Palladium 16500 take?
Standard UK super king sheets fit the 180 x 200cm footprint, and a 260 x 220cm duvet gives proper overhang on both sides. Bedding at this size costs more than king equivalents, so factor that in. A generous duvet also settles the nightly tug of war that pushes many couples to size up in the first place.
