Layer Details
- Knitted Cover. A soft knitted cover that breathes well, which means heat can escape rather than build up around you. It helps keep you at an even temperature all night.
- Reflex Foam. A soft layer of Reflex Foam that contours to the shape of your body, which means personalised support and pressure relief where you need it. It gives a comfortable surface without undermining the firm feel beneath.
- Pocket Springs. Individual pocket springs work independently, reacting to changes in your weight and movement. In practice that means responsive support at your pressure points and less motion transfer across the bed.

- A fit for most UK bedrooms: At 135 x 190cm, this size leaves space for wardrobes and drawers in an average room, where a UK king can leave you shuffling sideways past the footboard.
- Less partner disturbance at 67.5cm each: With 67.5cm each for two people sharing, the independent pocket springs matter more, which means one of you turning over is less likely to wake the other.
- Firm support across the full shared width: The extra firm build resists roll-together, so two sleepers of different weights each stay on their own side rather than drifting into the middle.
- Bedding that's easy and cheap to find: Double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, a small saving that adds up if you're furnishing a whole home.
- A guest room that welcomes couples: A UK double suits a spare room well, since visiting couples can share it and the firm, breathable knitted cover keeps it fresh between stays.
This size suits you if...
You share the bed every night and your room sits around the typical UK size, you're kitting out a first flat or whole house on a careful budget and want a firm mattress in the most widely available size, or you sleep alone and want spreading-out room without giving the bed the entire floor.
Consider another size if...
You and your partner both want more personal space than 67.5cm each and your room can take a bigger bed. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

Is the Coolflex Lux Ortho Pocket UK double big enough for a couple?
Yes, for most couples. At 135 x 190cm you get 67.5cm each for two people sharing, and the extra firm build stops you rolling into each other. Restless sleepers, or anyone over about six foot, may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Coolflex Lux Ortho Pocket in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows the door to open fully and leaves walking space on both sides. If you want bedside tables both sides, sketch the layout first: the 135cm width plus two tables fills a wall quickly in a smaller room.
Will a UK double fit in a second bedroom or first flat?
Usually, yes. The 135 x 190cm footprint is the standard shared size precisely because it works alongside a wardrobe and a chest of drawers in an ordinary room. Measure the free wall first, though. If space is genuinely tight, the UK small double is 15cm narrower and the same length, and we suggest at least 2.4m x 2.8m for it.
Should I get this mattress in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king, so it comes down to your room and how much space you each want. If your bedroom meets our suggested 2.7m x 2.9m for the UK king and you both value elbow room, size up. Otherwise the UK double keeps the room usable.
Is the double good for a solo sleeper?
Very much so. At 4ft 6in x 6ft 3in there's room to stretch out, or to share with a dog or cat that claims a corner, and the pocket springs mean a pet shifting about transfers little movement to you. Sleeping alone, you also feel the extra firm support consistently rather than only along your half.
