Layer Details
- Microquilted cover. A micro-quilted cover gives the sleep surface a smooth, soft finish. It takes a little of the edge off an otherwise firm mattress.
- Castellated foam. This medically-proven castellated foam layer minimises motion transfer. In practice, that means less disturbance when a partner turns over in the night.
- TrueGel Technology. Komfi's naturally cooling TrueGel technology helps regulate your temperature. Foam can run warm, so this layer works against that tendency.
- Reflex Foam. A core reflex support layer provides a firm, responsive foundation. This is where the mattress gets its orthopaedic-style, on-top-of-the-bed feel.
- Ecofoam. The base is a resilient, durable Ecofoam layer made from 100% recycled and re-engineered foam. It's also naturally dust-mite resistant, which allergy sufferers will appreciate.

- 90cm each, every night: Two people sharing get 90cm each, which means a restless partner can turn over without ever crossing into your half.
- Distance plus damping: The castellated foam layer reduces motion transfer, and at this width there's simply more mattress between you, so disturbance drops twice over.
- Firm support edge to edge: The reflex foam core gives the same on-top-of-the-bed feel across the full 180cm, so nobody ends up on a softer patch.
- Room for the whole household: If children or a large dog routinely join you before morning, the extra 30cm over a UK king keeps everyone with a workable share.
- Cooling across a big surface: TrueGel technology helps with temperature, useful because two bodies plus visiting children can make even a large foam bed run warm.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner fidgets and you'd rather solve it with distance as well as the motion-damping foam, or children and pets treat your bed as theirs and you've stopped fighting it. Your bedroom should measure at least 3m x 2.9m, and closer to 3.5m x 3.2m will feel comfortable.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

Is the KomfiMed Ortho Firm in a UK super king good for restless partners?
It's one of the better cases for this size. The castellated foam layer is designed to minimise motion transfer, and the 180cm width gives you 90cm each, so most turning happens too far away to register. Firm foam also tends to move less at the surface than a softer mattress, which helps further.
Will a UK super king KomfiMed Ortho Firm fit in my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling right. At 180 x 200cm the mattress dominates a smaller room, so check door swing, wardrobe access and space to walk down both sides before ordering. In a loft conversion, the slope may decide which wall the bed can take.
How hard is it to get a super king foam mattress upstairs?
Komfi doesn't publish a weight for this mattress, and at 180 x 200cm it's a single one-piece foam unit rather than zip and link halves, so there's no splitting it for the stairs. Measure any tight landing turns first, and plan on two people to move it.
Is the UK super king worth it over the UK king for this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. If children or pets join you at night, or one of you is a genuinely restless sleeper, that extra width does more for your sleep than any comfort layer. Sleeping alone, or in a smaller room, the UK king is the more sensible buy.
How much space does each person get on a super king?
Two people sharing get 90cm each, the same width as a UK single apiece. On this mattress that space comes with a firm, even reflex foam surface, so you won't roll towards the middle. It's the difference between sharing a bed and merely sharing a room.
