Layer Details
Microquilted cover
A micro-quilted cover gives the sleep surface a smooth, soft finish. It's the first thing you'll feel when you lie down.
Castellated foam
This foam is cut into grid-like sections, which means each zone can move independently. In practice, that helps the mattress adapt to different parts of your body.
TrueGel Technology
Komfi's specialised gel layer is designed for temperature regulation. If you're a hot sleeper, this is the layer doing the heavy lifting for you.
Pocket springs
A layer of 1000 adaptive pocket springs conforms to your body's contours. Each spring works on its own, which means support where you need it rather than a uniform push-back.
Ecofoam base
The base is made from recycled, re-engineered Ecofoam. It's a durable foundation with a lighter environmental footprint than virgin foam.

Key benefits
- Room for two without dominating the bedroom: At 4ft 6in x 6ft 3in, this is the traditional couples' footprint, which means it leaves space for a wardrobe and drawers in a typical UK bedroom.
- Bedside tables on both sides: In rooms around the 2.6m x 2.8m minimum we suggest, a UK double usually still allows a table each side, something a UK king often rules out.
- Independent springs matter more when you share: The 1000 pocket springs move on their own, which means your partner turning over transfers less movement across a bed you're both lying on.
- Cooling for two bodies' worth of heat: Two people sharing 135cm generate more warmth than one, so the TrueGel layer above the springs gives that heat a route away from you both.
- Easy to dress and move: Double bedding is stocked everywhere at every price, and this size is the most forgiving on turning stairs in older terraces and tight new build landings.
This size suits you if...
You share the bed every night and want the standard couples' size that still leaves your bedroom usable, or you sleep alone and like room to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since 67.5cm each for two people sharing is comfortable for occasional stays.
Consider another size if...
Your room comfortably exceeds 3m x 3m and you'd both appreciate more space. The UK king is 15cm wider and 10cm longer than the UK double; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Komfi GelMed Comfort UK double wide enough for a couple?
Yes, for most couples. You get 67.5cm each for two people sharing, and the 1000 pocket springs move independently, so one of you shifting disturbs the other less than a uniform surface would. If either of you sleeps starfished, or you're both restless, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Komfi GelMed Comfort double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance rather than Komfi's, and it assumes you want to walk round the bed and open drawers without shuffling sideways. In a room near the minimum, the UK double usually still leaves space for bedside tables on both sides.
Is a UK double Komfi GelMed Comfort good for a guest room?
It suits a guest room well. Visiting couples fit, solo guests get plenty of space, and the medium firm feel sits in the middle of the range, so it won't feel wrong to most people. The gel layer helps guests who run warm, though it's a more considered spec than occasional use strictly needs.
Will the double size fit up narrow stairs?
Of all the sizes this mattress comes in, the UK double is among the easier ones to manoeuvre, and it's a friendlier prospect than the UK king or UK super king on a turning staircase in an older terrace or a tight new build landing. Measure your narrowest turn before ordering, and check the retailer's delivery notes on this page.
What bedding fits the Komfi GelMed Comfort in a double?
Standard UK double bedding: sheets sized for 135 x 190cm and a 200 x 200cm double duvet. This is one of the quiet advantages of the size, since double bedding is stocked everywhere at every price point, so replacing or upgrading sheets never involves hunting for a specialist fit.
