Layer Details
- Microquilted cover. A micro-quilted cover gives the surface a smooth, soft finish. The cover is made with Seaqual yarn and is removable and washable, which makes it easier to keep fresh.
- Medically-proven castellated foam. This foam is shaped into grid-like sections that move independently, which means airflow through the comfort layer and less motion transfer to your side of the bed. The zones also distribute body weight more evenly.
- TrueGel Technology. A specialised gel layer that draws excess heat away from the body, which means a cooler feel through the night. It also adapts to your body's contours for targeted pressure relief.
- Pocket Springs. 1000 pocket springs adjust individually to your body shape, which means tailored support and healthy spinal alignment. Because each spring moves on its own, motion transfer is kept to a minimum.
- Reflex Foam. A supportive foam that moulds to your body and promotes spinal alignment. It's durable and resilient, holding its shape over an extended period.
- Ecofoam. A sustainable base foam that is durable, resilient and naturally dust mite resistant. It's made by a carbon neutral company and is 100% recyclable at end of use.

- Real space for two: At 150cm wide, the UK king is 15cm wider than a UK double, which means each of you gets room to turn without a nudge.
- Less disturbance across the width: Pocket springs move individually, so a partner getting up hours before you is far less likely to wake you on a bed this wide.
- Length for taller sleepers: The 200cm length adds 10cm over a UK double, a genuine relief if one of you is approaching six foot.
- Cool sleeping shared: The TrueGel layer draws heat away from the body, useful when two people are warming one mattress every night.
- Firm support at scale: The medium firm feel stays consistent edge to edge, so neither sleeper drifts toward the middle on the wider surface.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up earlier and the other wants to stay asleep. It also makes sense if one partner is tall, since the 200cm length gives welcome extra legroom, or if a dog has quietly claimed a share of the mattress and 75cm each no longer stretches far enough.
Consider another size if...
You have the room to go bigger and want the most space this mattress offers. The UK super king is 30cm wider than the UK king at the same length; we suggest allowing at least 3m x 2.9m for it.

How big is the Komfi GelMed Ortho in a UK king?
It measures 150 x 200cm, or 5ft x 6ft 6in. For two people sharing that works out at 75cm each, and the 25cm depth is the same across sizes. We suggest a room of at least 2.7m x 2.9m so you can walk around the bed comfortably.
Is the UK king Komfi GelMed Ortho good for couples?
Yes, and arguably it's the size this design suits best. The 1000 pocket springs and castellated foam both limit motion transfer, so on a 150cm width one partner shifting or getting up early is much less likely to disturb the other. Lightweight side sleepers may still find the medium firm feel a little solid.
Is a UK king Komfi GelMed Ortho long enough for tall sleepers?
At 200cm it's 10cm longer than a UK double, which is usually enough for anyone up to around six foot four. If one of you is tall, the length is often the bigger upgrade than the width. Sizing up to the UK super king adds width but no extra length.
Should we choose the UK king or the UK super king?
The UK king suits most couples: plenty of space without demanding a huge room. The UK super king is 30cm wider at the same length, worth it if children or pets regularly join you and your room allows at least 3m x 2.9m. The UK king needs at least 2.7m x 2.9m by our guidance.
