Layer Details
Knitted cover
A soft-to-touch knitted cover sits on top. It is the first thing you feel, and it is designed to be gentle rather than scratchy.
Luna Fusion Cool Memory Foam
A 2cm layer that moulds around your shape to ease built-up pressure at the hips and shoulders. Its open cell structure lets air pass through, which means it should sleep cooler than traditional memory foam.
Mini Pocket Springs
A layer of 2000 mini springs with small pockets for airflow, helping to dispel heat. They also add a comforting bounce-back feel, so you do not sink without response.
Reflex Foam
A 3cm layer of Reflex foam that reinforces the medium to firm comfort level. It acts as a transition between the softer top and the springs below.
Reflex Foam
A deeper 5cm layer of Reflex foam doing the same job, adding stability and firmness. Together the two foam layers stop you feeling the spring core directly.
Luna Pocket Springs
The sturdy core of 4000 Luna Pocket springs, each moving independently to give tailored full-body support. This is where the mattress earns its supportive, medium to firm character.
Foam encapsulated border
A foam wall around the edge provides durable edge support. In practice that means a reduced roll-off feel and a usable sleep surface right to the sides.

Key benefits
- Independent springs, quieter nights: The core of 4000 Luna Pocket springs moves independently, which means an early riser on one side sends far less movement across to the other.
- Room to sleep apart, together: With 75cm each for two people sharing, you can both change position freely, useful during pregnancy or when one of you is recovering from an injury.
- Length for taller sleepers: At 200cm long, this UK king adds headroom for anyone whose feet reach the end of a standard 190cm mattress.
- Edges you can actually use: The foam encapsulated border keeps the sides supportive, so sleeping near the edge on a shared bed feels stable rather than precarious.
- Cooler across a bigger surface: Gel-infused memory foam with an open cell structure and 2000 mini pocket springs help air move through, which matters more when two bodies share the bed.
This size suits you if...
You share the bed every night and a double has started to feel cramped, one of you gets up hours before the other, or someone in the bed is tall enough to want the 200cm length. It also suits couples in the broken-sleep stages of pregnancy or recovery, where space to shift position without waking a partner is the whole point of upgrading.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and gives up only 15cm of width.

FAQ's
Is the Luna 6000 in a UK king good for couples?
Yes, and it is arguably the size this mattress makes most sense in. You get 75cm each for two people sharing, and the core of 4000 independently moving pocket springs limits how much one partner's movement travels across the bed. The firm edge support means neither of you loses usable space at the sides.
How much bigger is the UK king Luna 6000 than the double?
The UK king is 15cm wider than the UK double and 10cm longer. That width is the difference most couples actually feel night to night, and the extra length helps taller sleepers. The construction and medium firm feel are identical in both sizes, so the choice comes down to space and your room.
What room size do I need for the Luna 6000 in a UK king?
We suggest allowing at least 2.7m x 2.9m, with more feeling comfortable once you add wardrobes and bedside tables on both sides. New build master bedrooms can be tighter than they look on paper, so measure with the furniture in mind, and remember the mattress itself is 150 x 200cm, or 5ft x 6ft 6in.
Is the UK king long enough for a tall sleeper?
At 200cm, or 6ft 6in, it gives noticeably more legroom than the 190cm of a UK single, small double or double. If one of you is over six foot, the length is often the real reason to size up, with the extra width a welcome bonus rather than the main event.
Should I choose the UK king or the UK super king Luna 6000?
The UK super king is 30cm wider than the UK king, and both are the same length, so it is purely a width decision. We suggest at least 3m x 2.9m for the UK super king, which rules out many rooms. If your bedroom takes it and you want maximum personal space, size up; otherwise the UK king is the sensible middle ground.
