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.

- Real space for two: At 75cm each for two people sharing, you can both settle into the medium to firm foam without negotiating elbow room.
- Motion isolation that matters more at this width: The castellated foam's independent zones limit movement transfer, so a partner on an earlier alarm can slip out with less disturbance.
- Length for taller sleepers: The UK king runs to 200cm, which stops feet hanging off the end for anyone approaching six foot.
- Cooling across a bigger surface: TrueGel technology and the ventilated foam sections draw heat away, useful when two bodies share one mattress every night.
- Fits most main bedrooms: We suggest allowing at least 2.7m x 2.9m, which most UK master bedrooms can manage once wardrobes are in place.
This size suits you if...
You share the bed every night and a UK double now feels cramped, or one of you keeps different hours and wants the combination of width and this foam's motion isolation to protect the other's sleep. It also suits couples where one partner is tall: the 5ft x 6ft 6in footprint adds length as well as width, and a dog who claims a corner becomes far less of a problem.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m minimum. The UK double would suit you better, and we suggest at least 2.6m x 2.8m for the UK double, so it fits where a UK king can't.

Is a UK king big enough for a couple on the KomfiMed Pro Medium?
Comfortably, for most. You get 75cm each for two people sharing, and because the castellated foam is cut into independently moving sections, that width does more here than on a conventional foam bed: your partner's turning is both further away and better absorbed. Very restless pairs who want maximum separation could consider the UK super king.
Will the KomfiMed Pro UK king fit in my bedroom?
The mattress measures 150 x 200cm, and we suggest a room of at least 2.7m x 2.9m so you can walk round both sides and open drawers without shuffling sideways. New build master bedrooms often look generous empty but shrink once fitted wardrobes go in, so measure the usable floor rather than the wall-to-wall figure.
Is the KomfiMed Pro king long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than the UK double, and for taller sleepers that length is often the real upgrade rather than the width. A back or stomach sleeper around six foot, the sleeping styles this medium to firm foam suits best, should fit without their feet reaching the edge.
Should I choose the KomfiMed Pro in a king or a super king?
The UK king is 30cm narrower than the UK super king, and the two are the same length. If your room meets our suggested 3m x 2.9m minimum for the UK super king and you want maximum personal space, size up. If space is tighter, the UK king still gives a couple room to sleep well.
Does a king size help if my partner gets up earlier than me?
It helps twice over on this mattress. The extra width means they can get out without climbing past you, and the castellated foam's independent zones reduce how much of that movement travels across the surface. Across a 150cm width, most of their side's motion fades before it reaches yours.
