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
- Sensible space for two: At 67.5cm each for two people sharing, a couple gets the traditional UK shared width, which works well given the mattress's supportive, no-sink surface.
- Springs that move independently: The 4000 Luna Pocket springs in the core respond to each sleeper separately, so a partner turning over at 2am is less likely to wake you.
- Edge support matters more at this width: The foam encapsulated border keeps the surface usable right to the sides, which counts when two of you are dividing 135cm.
- Fits most UK bedrooms: We suggest a room of at least 2.6m x 2.8m for a UK double, comfortably achievable in most terraces, flats and new builds.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit this size, and both are sold everywhere at every price point.
This size suits you if...
You share the bed every night and want the classic couples' size in a room where a UK king would crowd the walkways, or you sleep alone and like space to stretch out. It also suits a guest room that hosts visiting couples, since the medium firm feel is a safe middle ground for back and front sleepers you can't ask in advance.
Consider another size if...
Your bedroom is generously sized and one of you is a restless sleeper who crosses the centre line. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and we suggest a room of at least 2.7m x 2.9m for it.

FAQ's
Is the Luna 6000 in a UK double firm enough for two sharers of different weights?
The core of 4000 pocket springs moves independently under each sleeper, so a heavier partner gets support without dragging the lighter one into a dip. The medium firm feel suits back and front sleepers well, although a lightweight side sleeper sharing may find it slightly unforgiving at the shoulder.
Can I fit a UK double Luna 6000 with bedside tables on both sides?
Usually, yes. The mattress is 135cm wide and we suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. In a room near the minimum, slim tables on each side should still leave walking space, though measure your own layout first.
Will the Luna 6000 double get up a narrow staircase?
It's a 27cm-deep hybrid with two spring layers, so it won't roll up or fold like an all-foam mattress. In an older terrace with a turning staircase or a tight new build landing, measure the awkward corner against the 135 x 190cm footprint before ordering, and check the retailer's access policy.
Is the Luna 6000 UK double a good choice for a guest room?
It's a reasonable one. A UK double gives visiting couples the standard shared size, and the medium firm feel is a middle-of-the-road choice when you don't know your guests' preferences. The foam encapsulated border also helps guests perching on the edge, though soft-mattress lovers may find it a little solid.
Should I get the Luna 6000 in a double or small double for a smaller room?
The UK double is 15cm wider than the UK small double and the two are the same length, so the saving is in width only. If your room falls below our suggested 2.6m x 2.8m for a double, the UK small double would suit you better; we suggest at least 2.4m x 2.8m for that size.
