Layer Details
Luna Fusion Cool Memory Foam
A 2cm layer with an open cell structure, which means better airflow and a cooler feel than standard memory foam. It adapts around your body for a cosy, cradled comfort.
Reflex Foam
A 3cm layer of reflex foam that adds cushioning. This is part of what gives the mattress its plush feel.
Reflex Foam
A second, deeper 5cm reflex foam layer continuing that soft cushioning. Together the two layers create the plush surface the name promises.
Mini Pocket Springs
A layer of 2,000 mini springs sitting between the foam and the main spring core. These add breathability and a gently bouncy feel.
Luna Pocket Springs
The core of 4,000 Luna Pocket springs, each encased in its own fabric pocket. Every spring moves independently, which means support tailored to your shape and less disturbance from a restless partner.

Key benefits
- 75cm each for two sharers: Each of you gets 75cm of width, which means turning over or stretching out without pushing the other person to the edge.
- Space plus pocket springs equals quieter nights: The 4,000 pocket springs move independently, and the wider surface of a UK king means a restless or early-rising partner disturbs you even less.
- Extra length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, so anyone approaching six foot stops sleeping with their feet at the very end.
- A noticeable step up from a double: The UK king is 15cm wider than the UK double, a difference you feel every night rather than a spec-sheet detail.
- Room for the routine intruders: The plush foam surface plus the added width leaves space for a dog that treats the bed as its own, without either of you losing sleep over it.
This size suits you if...
You share the bed every night and the two of you have outgrown a double, you and your partner keep different hours and want the pocket springs and extra width working together to soften the disturbance, or one of you is tall enough that the 200cm length is the real upgrade. It also suits couples who like a soft, cradling surface but need proper personal space to enjoy it.
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. We'd recommend the UK double instead, which needs a slightly smaller room at 2.6m x 2.8m.

FAQ's
Is the Luna 6000 in a UK king big enough for a couple?
Yes, comfortably. At 150 x 200cm you get 75cm of width each, and the 4,000 pocket springs respond to each sleeper separately, so a partner shifting position or getting up early is far less likely to wake you. Couples who find a double a squeeze usually feel the difference straight away.
What room size do I need for the Luna 6000 UK king?
We suggest a room of at least 2.7m x 2.9m so you can walk round the bed and open drawers without shuffling sideways. New build master bedrooms can be tighter than they look once wardrobes go in, so measure the usable floor space rather than the room itself before ordering.
Is the UK king Luna 6000 long enough for someone over six foot?
At 200cm, or 6ft 6in, it gives a tall sleeper genuinely useful legroom, and it's 10cm longer than the UK double. For many couples where one partner is over six foot, that extra length is the real reason to size up, with the added width a welcome bonus.
Should I choose the Luna 6000 in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king, and both are the same length. If you share with a restless partner, children or a dog and your room allows at least 3m x 2.9m, the UK super king is the roomier choice. For most couples, the UK king is space enough.
Where can I buy the Luna 6000 in a UK king?
Availability is limited for this model, so compare the retailers listed on this page; the prices shown here are updated as retailers change them. Stock and pricing can shift between sizes, so it's worth checking the UK double and UK super king pages too if you're undecided.
