Layer Details
Knitted cover
A soft knitted finish that adds a little cosiness and warmth. It also enhances airflow and breathability, which helps you sleep cooler.
Copper layer
A thin layer of pure copper that is highly conductive, drawing excess heat away from your body as you sleep. Copper is also naturally antimicrobial, a reassuring bonus for allergy-conscious sleepers.
Memory Foam
30mm of memory foam that cradles your body shape, which means pressure points like hips and shoulders get some relief. It's a modest layer, in keeping with the firm feel.
Reflex Foam
Layers of reflex foam that add support and protect the spring system beneath. This section also includes foam encapsulated edge support, so the sides stay stable when you sit or sleep near the edge.
Pocket Springs
A core of 2000 pocket springs, each encased in its own fabric pocket. They respond individually to weight and movement, which means responsive support and less disturbance from a restless partner.

Key benefits
- 90cm each for two people sharing: Each of you gets 90cm of width, which means a fidgeting partner is far enough away that their movement barely reaches you.
- 2000 pocket springs limit disturbance: Each spring responds individually to weight and movement, and across this much width that isolation matters more, so a restless sleeper stays their side of the bed.
- Room for the whole household: When a child or a large dog joins you in the small hours, this size absorbs the extra body without anyone losing their share.
- Edge support you can actually use: Foam encapsulated edges keep the sides stable, so all 180cm of width is usable sleeping space rather than a no-go zone near the rim.
- Copper cooling under two sleepers: Two bodies generate more heat than one, and the conductive copper layer draws that warmth away rather than letting it build between you.
This size suits you if...
You share the bed every night and a UK king still feels like a compromise, your partner is genuinely restless and distance matters more to you than any comfort layer, or children and pets treat your bed as theirs too. Your room should be at least 3m x 2.9m, and around 3.5m x 3.2m feels right for this size.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest, or the bed would dominate the space. The UK king is 30cm narrower and the same length, and we'd recommend it instead; allow at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on the Copper Fresh Envy Supreme super king?
Two people sharing get 90cm of width each. Combined with the 2000 pocket springs, which respond individually to weight and movement, that distance means a partner turning over in the night is much easier to sleep through than on a narrower size.
Is the Copper Fresh Envy Supreme super king good for restless partners?
It's one of the better cases for this size. The individual pocket springs already limit motion transfer, and 90cm of width each adds physical distance on top. If one of you fidgets or keeps different hours, the UK super king does more for your sleep than any comfort layer could.
Will the Copper Fresh Envy Supreme super king fit in my bedroom?
The mattress measures 180 x 200cm, and we suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. Check door swing and any tight landing turns before ordering, as a mattress this size is the one most likely to struggle on stairs.
Should I choose the UK king or the UK super king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. If you share with a restless partner, or children and pets regularly join you, the extra width is what you're paying for. In a room under 3m x 2.9m, the UK king is the sensible pick.
Does the copper layer still work well at super king size?
Yes. The conductive copper layer sits near the surface across the full 180cm width, drawing heat away wherever you lie. That matters slightly more at this size, since two adults, and sometimes a child or dog as well, put more warmth into the bed than one sleeper would.
