Layer Details
- Knitted cover. A soft knitted cover that adds a touch of cosiness and warmth. Knitted covers also enhance airflow, so the surface stays breathable.
- Luna Fusion Cool Memory Foam. A 4cm layer of memory foam with an open cell structure, which means it breathes better and feels cooler than standard memory foam. You get the contouring without as much of the heat.
- Reflex Foam. Reflex foam in 2cm and 3cm layers adds cushioning and reinforces the medium to firm feel. It moulds to your body while promoting spinal alignment.
- Luna Pocket Springs. A core of 2500 Luna pocket springs, each encased in its own cloth pocket. They respond individually to movement, which means personalised support and less disturbance when a partner shifts.

- Space to stop negotiating: At 150 x 200cm you each get 75cm of width, which means an elbow room upgrade you notice the first night you share it.
- Movement stays on one side: Each of the 2500 springs sits in its own cloth pocket, so a partner leaving for an early shift is far less likely to wake you.
- Length for taller sleepers: The UK king runs 10cm longer than the UK double at 200cm, a real difference if one of you is nudging six foot.
- Cool foam across a wider surface: The 4cm Fusion Cool layer has an open cell structure, which means two bodies' worth of warmth escapes rather than building up between you.
- Firm support that shares well: The medium firm feel holds its shape across the full width, so neither sleeper rolls towards the middle when weights differ.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, especially if one of you gets up hours before the other and the slightest movement carries. It also makes sense if one partner is tall enough to find 190cm beds a little short, or if a dog has quietly claimed a strip of the mattress and you'd like your share back.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case the UK double works in rooms from 2.6m x 2.8m, and its medium firm feel is identical, so you lose 15cm of width but nothing in support.

Is the Luna Memory 2500 in a UK king good for couples with different sleep schedules?
Yes, and this is where the size and the construction help each other. The 2500 individually pocketed springs absorb movement locally, so an early riser shifting or getting out is less likely to travel across the bed. Combined with 75cm each for two people sharing, one of you can move without the other feeling every inch of it.
Will a UK king Luna Memory 2500 fit in a new build master bedroom?
Often, but measure first. New build masters can feel smaller than the floor plan suggests once wardrobes go in, and we suggest at least 2.7m x 2.9m for a UK king so you can still walk round it. If your room is tighter, the UK double needs a slightly smaller 2.6m x 2.8m.
Is the UK king Luna Memory 2500 long enough for someone over six foot?
At 200cm long it gives you 10cm more than the UK double, which for most people around the six foot mark is the difference between feet on the mattress and feet hanging off it. The medium firm support runs the full length, so taller sleepers get proper alignment right to the edge rather than a soft border.
Should we choose the Luna Memory 2500 in a UK king or a UK super king?
The UK king suits most couples: the UK super king adds 30cm of width but the two sizes are the same length, and we suggest at least 3m x 2.9m of room for the UK super king. If a dog or a child regularly joins you, that extra width earns consideration. Otherwise the UK king is the more practical fit.
How much does the Luna Memory 2500 cost in a UK king?
Prices change often enough that quoting one here would mislead you within days, so we show live figures instead. Compare the retailers listed on this page; the prices shown are updated as retailers change them. As a size, the UK king typically sits between the UK double and UK super king in any brand's range.
