- 90cm of width each: Two people sharing get 90cm each, which means you can both stretch out without ever brushing elbows in the night.
- Calico springs keep movement local: Each spring is sewn into its own cotton pocket, so a partner turning over on their side stays felt on their side.
- Room for the whole household: If children or pets treat your bed as theirs, the extra 30cm over a UK king is often the difference between sleep and a knee in your back.
- Edges you can actually use: Three rows of hand side-stitching firm up the perimeter, which matters at this size because usable edge space is part of what you're paying for.
- Natural fillings across a big surface: Cashmere, silk and British wool help regulate temperature, and with two bodies under one 260 x 220cm duvet that breathability does real work.
This size suits you if...
You share the bed every night and want the maximum space a standard UK size offers, one of you is a genuinely restless sleeper, or children and pets regularly join you and a UK king has started to feel crowded. It also suits a large master bedroom, particularly in a period property, where a smaller bed can look lost against the proportions of the room.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 3m x 2.9m, or the bed would leave no walking space around it. 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 Flaxby Platinum Lunar super king big enough for a couple with children joining them?
For most families, yes. At 180cm wide it gives two adults 90cm each, so when a child climbs in there's usually still a fair share for everyone. The calico pocket springs also respond to each body independently, which means a small visitor fidgeting at dawn disturbs the adults less than you might expect.
What room size do I need for the Flaxby Platinum Lunar in a UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable. That's our own guidance, based on leaving space to walk around the bed and open wardrobe doors. In a loft conversion, check the ceiling slope too, as it can dictate which wall a bed this wide sits against.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All the extra space goes into width, which is exactly where a couple feels it: it's the difference between sleeping close by choice and sleeping close because there's nowhere else to go.
Is the Flaxby Platinum Lunar super king good for a restless partner?
It's one of the stronger cases for this size. Distance does more than any comfort layer, and 90cm each puts real space between you. On top of that, the calico pocket springs move independently, so a partner who turns over frequently sends far less motion across the bed than a standard sprung mattress would.
Is the Flaxby Platinum Lunar super king difficult to move and turn?
It takes planning. A 180 x 200cm pocket sprung mattress with natural fillings is heavy and awkward on stairs, so measure door frames and landing turns before ordering. It's also dual-sided and needs flipping to wear evenly, which is firmly a two-person job at this size. Factor in super king bedding and a 260 x 220cm duvet as well.
