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
- Fits the average British bedroom: At 135 x 190cm, or 4ft 6in x 6ft 3in, it sits comfortably in rooms where a UK king would crowd the walls.
- Room for bedside tables on both sides: In most doubles-sized bedrooms this footprint still allows a table each side, which matters more day to day than a few extra centimetres of mattress.
- Castellated foam earns more at this width: With 67.5cm each for two people sharing, the independently moving foam zones limit how much a partner's turning reaches your side.
- Cooling for two: Two bodies raise the temperature under the duvet, so the TrueGel layer drawing heat away is more useful here than in a solo size.
- Easy to dress: Standard double sheets and duvets are stocked everywhere, so replacing bedding never becomes a hunt.
This size suits you if...
You share the bed most nights and your room simply won't take a UK king, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner, without the bed dominating the room. It also suits a guest room that hosts visiting couples, since the medium to firm feel is a safe middle ground for sleepers you can't predict.
Consider another size if...
You and your partner are both broad or restless and 67.5cm each feels tight. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double, and we suggest a room of at least 2.7m x 2.9m for it.

FAQ's
What size room do I need for the KomfiMed Pro in a UK double?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows the door to open fully and leaves walking space on both sides. If your room meets the minimum but little more, expect a snug fit with bedside tables, a workable one.
How much space does each person get on the KomfiMed Pro UK double?
The UK double gives 67.5cm each for two people sharing. That's the long standing standard for couples, though it feels closer than a UK king if either of you is broad shouldered or spreads out in the night. The castellated foam helps here, as each grid section moves independently, so a partner shifting position is less likely to wake you.
Is the KomfiMed Pro UK double or UK king better for a couple?
It depends on your room more than the mattress. The UK double is 15cm narrower and 10cm shorter than the UK king, and needs less floor space: we suggest at least 2.6m x 2.8m for the UK double against 2.7m x 2.9m for the UK king. If the larger room guidance is comfortably met and you both value space, size up.
Does the KomfiMed Pro double work in a guest room?
Yes, and it's a sensible pick. The 135 x 190cm footprint fits most spare rooms, it sleeps visiting couples rather than forcing them into a single, and the medium to firm feel is a reasonable middle ground for guests whose preferences you can't know in advance. The cooling layers are a quiet bonus for anyone who runs warm.
Will the KomfiMed Pro UK double sleep cool with two people sharing?
Two sleepers generate noticeably more heat than one, which is where this mattress makes its case at this size. The TrueGel layer draws warmth away and the castellated foam's grid sections let air move through the surface, so heat isn't trapped between you the way it can be on traditional solid foam.
