Layer Details
Micro-quilted cover
A soft knitted cover with thin layers of fabric and padding stitched together, which means a smooth, slightly plush surface feel from the moment you lie down. It's the gentlest part of an otherwise medium to firm mattress.
TrueGel Technology
Komfi's grid-like gel layer regulates body temperature by drawing heat away from you. If you're a hot sleeper, this is the layer doing the most work on your behalf.
Medically-proven castellated foam
Foam cut into grid-like sections that move independently, promoting airflow and minimising motion transfer. In practice, that means better temperature control and less disturbance when a partner shifts position.
Reflex Foam Support system
A durable, resilient base foam that moulds to your body and promotes spinal alignment. It gives the mattress its supportive, medium to firm character.

Key benefits
- Distance plus motion isolation: At 90cm each, you and a restless partner are far apart to begin with, and the independently moving castellated foam sections damp down what movement remains.
- Space for night-time visitors: When a child or a large dog treats your bed as their own, a UK super king absorbs the extra body without anyone sleeping on the edge.
- 30cm wider than the UK king: Same 200cm length, so tall sleepers lose nothing, but the extra 30cm of width is what turns a shared bed into an undisturbed one.
- Cooling that suits a shared bed: Two bodies generate more heat than one, so the TrueGel layer and airflow through the castellated foam matter more at this size than any other.
- Fills a large master properly: In a period property or generous new build master, a UK king can look lost; the 6ft width sits in proportion with the room.
This size suits you if...
You share the bed every night and want genuine distance from a partner who turns over a lot, your children or pets regularly join you and everyone still needs their own space, or your master bedroom is large enough that a smaller bed would look undersized in it. It also suits hot-sleeping couples, since the gel and airflow layers work hardest when two people share.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you mostly sleep alone. The UK king would suit you better: 30cm narrower, the same 200cm length, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the KomfiMed Pro super king good for a restless partner?
It is one of the better pairings for one. The castellated foam is cut into grid-like sections that move independently, so movement transfers poorly across the surface, and the 90cm each of a UK super king adds physical distance on top. Between the two, most partner disturbance simply stops reaching you.
Will the KomfiMed Pro super king fit in a 3m x 2.9m bedroom?
Yes, though only just. We suggest 3m x 2.9m as the minimum room for a UK super king, which leaves enough space to walk round the bed and open wardrobe doors. Around 3.5m x 3.2m feels comfortable rather than tight. Measure the room and check the door swing before ordering.
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. The feel and 25cm depth of the KomfiMed Pro Medium are identical across sizes, so the decision comes down to width, your room, and the higher cost of super king bedding.
Is the super king big enough to share with children or a dog?
Realistically, yes. Two adults get 90cm each, so a child wandering in at night or a large dog claiming the foot of the bed still leaves everyone a workable share. In smaller sizes the same visitors push someone to the edge, which is often the reason couples size up to a UK super king.
How heavy is the KomfiMed Pro super king to move upstairs?
Komfi doesn't publish a weight for this size, so check with the retailer before delivery day. As an all-foam mattress it has some flex on a tight landing, but at 180 x 200cm it is an awkward carry, and we'd plan for two people. Measure stair turns and door frames first.
