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.

Key benefits
- Distance plus isolation: The 1000 pocket springs move independently to limit motion transfer, and at 90cm each the movement starts further from you in the first place.
- Room for night-time visitors: When a child pads through at 3am, a UK super king absorbs the extra body without anyone hanging off the edge.
- Cool across the full width: The TrueGel layer draws heat away from the body, useful when three people or a large dog are warming the same bed.
- Firm support for two different builds: The medium firm feel suits back and front sleepers and heavier side sleepers, so mismatched partners often both get on with it.
- Airflow through the comfort layer: The castellated foam is cut into grid-like sections that let air move, which matters more the more bodies the bed holds.
This size suits you if...
You share the bed every night and want a genuine buffer from a partner who turns constantly, your children or pets treat your bed as communal territory, or you have a large master bedroom where a UK king would look undersized. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling more comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or the extra bedding cost puts you off. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
What size is the Komfi GelMed Ortho super king?
It measures 180 x 200cm, or 6ft x 6ft 6in in imperial. That's a full 6ft of width, matching two 90cm singles side by side, and it's the largest size the GelMed Ortho comes in. You'll need super king sheets and, ideally, a 260 x 220cm duvet.
Is the Komfi GelMed Ortho super king good for restless couples?
It's one of the stronger cases for this size. The 1000 pocket springs adjust individually and the castellated foam sections move independently, so movement transfers poorly across the surface. Add 90cm of width each and most turning simply happens too far away to notice.
What room do I need for the Komfi GelMed Ortho super king?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels right if you want bedside tables on both sides and space to walk around comfortably. Check door swing and any landing turns too; a rolled mattress helps here, since the GelMed Ortho arrives compressed for delivery.
Should I choose the Komfi GelMed Ortho in a UK king or super king?
The UK super king is 30cm wider than the UK king, and the two are the same length. If a partner's movement wakes you, or children and pets regularly join you, the extra width is worth having. In a smaller room, the UK king suits at least 2.7m x 2.9m of floor space.
Does the Komfi GelMed Ortho super king sleep cool with children in the bed?
It's better equipped than most. The TrueGel layer draws excess heat away from the body, and the grid-cut castellated foam allows airflow through the comfort layer. More sleepers means more warmth, but the 180cm width lets everyone spread out rather than huddle. Compare the retailers listed on this page for current prices.
