Layer Details
- Room to sleep apart, together: At 75cm each for two people sharing, you both get proper personal space, which means fewer accidental elbows and less repositioning through the night.
- Less disturbance on different schedules: If one of you gets up hours before the other, the independent calico pocket springs keep movement localised, so an early alarm is less likely to wake the late riser.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, which means anyone approaching 6ft finally stops grazing the footboard.
- Natural fillings across a bigger surface: Cashmere, silk, British wool, hemp and flax regulate temperature naturally, useful when two bodies share one mattress and one of you runs warm.
- Edges you can actually use: Three rows of hand side-stitching firm up the sides, so the full 150cm width is usable rather than a no-go zone near the edge.
- Standard bedding, no hunting: At 27cm deep in a standard UK king footprint, regular king fitted sheets and a 230 x 220cm king duvet fit without special ordering.
This size suits you if...
You share the bed every night and a double has started to feel like a negotiation, you and your partner keep different hours and want movement to stay on one side of the bed, or one of you is approaching 6ft and needs the 200cm length. It also suits couples whose dog treats the bed as its own; the extra width absorbs that better than a double does.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, which needs a slightly smaller room at 2.6m x 2.8m.

Is the Flaxby Platinum Lunar in a UK king good for couples?
Yes, and arguably it's the size this construction was made for. Two people sharing get 75cm each, and because every calico pocket spring is sewn into its own cotton pocket, your partner's movement stays on their side. The hand side-stitched edges mean you can use the full width without feeling you might roll off.
What room size do I need for a UK king Flaxby Platinum Lunar?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables go in. New build master bedrooms can be tighter than they first appear, so measure the floor space that's left after furniture rather than the room itself before committing.
Is the UK king Flaxby Platinum Lunar long enough for tall sleepers?
At 200cm, or 6ft 6in, it gives you 10cm more length than the UK double, which is the difference between feet on the mattress and feet hanging off it for anyone around the 6ft mark. If it's length you need, the UK super king offers the same 200cm, so the UK king gets you there without the extra width.
Is the Flaxby Platinum Lunar hard to flip in a king size?
It's dual-sided and needs turning to wear evenly, and at 150 x 200cm with dense natural fillings this is realistically a two-person job. If you live alone or have a back injury, factor that in; a smaller size is easier to handle, but any king mattress of this build will take some effort.
