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.

- Room to sleep apart, together: At 75cm each for two people sharing, you can both stretch out without negotiating the middle ground every night.
- Less disturbance from a restless partner: The 1000 pocket springs compress independently, which means an early alarm on one side transfers less movement to the other.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a genuine relief if either of you is nearing six foot.
- Cooler across a wider surface: The TrueGel layer runs the full 150cm width, so two warm bodies sharing the bed still have somewhere for heat to go.
- Zoned comfort for two different builds: The castellated foam flexes in independent sections, which means each side of the bed adapts to the person on it.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, particularly if one of you gets up hours before the other and you'd rather not feel it. It also fits if either partner is tall, since the 200cm length gives feet somewhere to go, or if you run warm as a pair and want the TrueGel layer working across a proper amount of space.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. The UK double of this mattress would suit you better, and needs a slightly smaller room, at least 2.6m x 2.8m.

Is the Komfi GelMed Comfort UK king wide enough for a couple?
Comfortably, for most. You get 75cm each for two people sharing, 15cm more across the bed than the UK double, and the pocket springs keep each side feeling like its own territory. If you share with a dog who claims a corner as a matter of routine, the extra width absorbs that rather than squeezing one of you.
What room size do I need for the Komfi GelMed Comfort in a UK king?
We suggest at least 2.7m x 2.9m. That leaves walking space on both sides and room for bedside tables. Be a little careful in new build master bedrooms, which often feel roomy until the wardrobes go in, so measure with furniture in place rather than from the floor plan.
Is the UK king Komfi GelMed Comfort long enough for tall sleepers?
At 200cm long, it's 10cm longer than the UK double, and for anyone around six foot that extra length is often the real upgrade rather than the width. Feet stay on the mattress instead of hanging past the end, which matters more than it sounds over a full night.
Will I feel my partner moving on this mattress in a king?
Less than on many spring beds. The 1000 pocket springs work independently and the castellated foam is cut into sections that flex on their own, so movement on one side has less route across the bed. If your schedules differ, one of you leaving early is far less likely to wake the other.
Does the king size feel different from the smaller sizes of this mattress?
The construction and Medium Firm feel are identical, so it won't feel softer or firmer than the UK double. What changes is the space: 15cm more width and 10cm more length than the UK double, which mostly shows up as fewer accidental elbows and less disturbance when one of you shifts position.
