Layer Details
Microquilted cover
A micro-quilted cover gives the sleep surface a smooth, soft finish. It's the first thing you'll feel when you lie down.
Castellated foam
This foam is cut into grid-like sections, which means each zone can move independently. In practice, that helps the mattress adapt to different parts of your body.
TrueGel Technology
Komfi's specialised gel layer is designed for temperature regulation. If you're a hot sleeper, this is the layer doing the heavy lifting for you.
Pocket springs
A layer of 1000 adaptive pocket springs conforms to your body's contours. Each spring works on its own, which means support where you need it rather than a uniform push-back.
Ecofoam base
The base is made from recycled, re-engineered Ecofoam. It's a durable foundation with a lighter environmental footprint than virgin foam.

Key benefits
- 90cm each, every night: Two people sharing get 90cm each, which means one of you can turn over without dragging the duvet or the other sleeper with them.
- Pocket springs suit the extra width: The 1000 pocket springs move independently, so movement on one side of this 180cm width barely travels to the other.
- Room for the whole household: If children or a large dog find their way in most nights, this is the size where everyone still keeps a fair share of the bed.
- Cool sleeping at scale: The TrueGel layer channels heat away from your body, and with 90cm each you're less likely to share your partner's warmth too.
- 30cm wider than the UK king: The UK super king is 30cm wider than the UK king and the same length, and that extra width is where the undisturbed feel comes from.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is restless enough that distance matters more than any comfort layer, or children and pets regularly join you and a UK king has started to feel crowded. A larger master bedroom also helps: a smaller bed can look lost in a big room, and this size fills it properly.
Consider another size if...
Your bedroom can't comfortably take a 180 x 200cm bed, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower and the same length, and we suggest at least 2.7m x 2.9m of room for it.

FAQ's
What room size do I need for the Komfi GelMed Comfort super king?
We suggest a minimum of 3m x 2.9m for a UK super king, which leaves walking space around a 180 x 200cm mattress. That's our guidance rather than Komfi's, and it assumes bedside tables on both sides. If your room is tighter than that, the UK king needs at least 2.7m x 2.9m and may sit better.
Is the Komfi GelMed Comfort super king good for restless couples?
It's a strong match. The width gives you 90cm each, so most movement happens too far away to notice, and the 1000 pocket springs work independently rather than transferring motion across the bed. Distance does most of the work here; the springs handle the rest. Lightweight sleepers may still register a heavier partner's bigger movements.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All 30cm goes into sleeping width, taking each person from a snug share to a generous 90cm. If the extra width appeals but the room is borderline, measure carefully before committing: 30cm changes how a room feels.
Can a family share the Komfi GelMed Comfort in a super king?
This is the size for it. When a child wanders in at 3am, a 180cm width means the adults keep a reasonable amount of space rather than clinging to the edges. The castellated foam flexes in independent sections too, so lighter and heavier bodies each get support that suits them rather than a uniform push-back.
Will a super king mattress overheat with two people in it?
Two bodies do add warmth, but this size helps in two ways. The TrueGel layer is designed to move heat away rather than trap it in the foam, and 90cm each means you're sleeping further from your partner's body heat than in a UK double or king. Hot-sleeping couples are exactly who this combination suits.
