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.

- 90cm each, every night: With 90cm each for two people sharing, a fidgety partner becomes something you notice rather than something that wakes you.
- 2500 pocket springs across the full width: Each spring responds individually, which means movement on one side of a 180cm-wide bed barely reaches the other.
- Cooler with more bodies aboard: Two adults plus a wandering child generate real heat, and the open cell Fusion Cool memory foam breathes better than standard memory foam under that load.
- Medium firm structure for family pile-ons: The reflex foam and medium to firm feel keep the surface stable when children or pets land on it at 6am.
- As big as standard sizes go: At 180 x 200cm the UK super king is the maximum mainstream size, so nobody in the bed has to negotiate for space.
This size suits you if...
You share every night and a restless partner regularly wakes you, so distance matters as much as comfort. Children or a large dog join you often enough that a UK king already feels crowded. Your bedroom clears our suggested 3m x 2.9m minimum, or you have a large master where a smaller bed would look lost.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m minimum, or you sleep alone most nights. We'd recommend the UK super king's sibling, the UK king, instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

How much space do two people get on a Luna Memory 2500 UK super king?
You get 90cm each for two people sharing, the same width each as a UK single would give you. On this mattress that space works harder than usual, because the 2500 pocket springs respond individually, so your partner's half behaves almost like a separate bed.
Is the Luna Memory 2500 super king good for restless partners?
It's one of the better cases for this size. Pocket springs already limit motion transfer, and at 180cm wide the movement has further to travel before it reaches you. A genuinely restless sleeper is easier to live with when distance and individually responding springs are both working in your favour.
Should I choose the Luna Memory 2500 in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king; the two are the same length. If children or pets join you, or one of you sleeps restlessly, that extra width is the difference. Allow at least 3m x 2.9m for the UK super king, or 2.7m x 2.9m for the UK king.
Can children or pets share a Luna Memory 2500 UK super king?
This is the size built for exactly that. A child wandering in at 3am, or a large dog who considers the bed a shared asset, still leaves two adults with usable space. The medium to firm feel also means the surface stays supportive rather than sagging when extra weight lands unevenly.
