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.

- Fits the smallest bedrooms: At 90cm wide it leaves room for a wardrobe, desk and toy storage in a child's bedroom where every metre of floor is contested.
- Cooling for warm rooms: The TrueGel layer and castellated foam draw heat away, which matters in small box rooms and loft spaces that warm up quickly.
- Grows with a teenager: The medium to firm reflex foam base supports spinal alignment through growth spurts, without the deep sink softer foam beds give.
- Two singles, one room: Siblings sharing, or a guest room set up with two beds rather than one, works because each UK single needs only a 3ft strip of floor.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and lowest priced of any UK size, which keeps running costs down for a kids' or guest bed.
This size suits you if...
You're buying for a child or teenager and want a supportive foam bed that keeps them cool at night, you need a spare room bed that leaves space for a desk or storage, or you sleep alone in a compact room and prefer a medium to firm feel over a sink-in one.
Consider another size if...
You're an adult who wants space to stretch out, or you share the bed even occasionally. We'd recommend the UK double instead: it's 45cm wider and the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

Will the KomfiMed Pro Medium UK single fit a bunk bed or mid sleeper?
Check your frame's maximum mattress depth first. The KomfiMed Pro Medium is 25cm deep, which is on the thicker side for raised frames, and many bunks specify a shallower mattress so the guard rail stays high enough. The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames.
Is the KomfiMed Pro Medium single a good mattress for a child?
It suits older children and teenagers well: the medium to firm reflex foam supports growing spines, and the castellated foam keeps a small bedroom's warmth from building up in the bed. Very light children may find it slightly firm at first, as the surface needs some body weight to contour.
What room size do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single, which leaves room to walk round the bed and open drawers. That makes it a comfortable fit in box rooms, lofts with a narrow usable strip under the slope, and spare rooms that double as an office.
Can two KomfiMed Pro single mattresses go in one room?
Yes, and it's a sensible setup for siblings sharing or a guest room that needs to sleep two people who aren't a couple. Each UK single is 90cm wide, so plan for both beds plus a walkway between them. The castellated foam limits motion transfer, though separate beds remove the issue entirely.
