Layer Details
Cover
A soft-touch cotton-viscose cover with embroidered detailing, which means the surface feels smooth rather than scratchy. It's treated with M-Pure, a plant-based fire-resistant finish, so fire safety is handled without chemical-heavy treatments.
Comfort fillings
Blended layers of 100% Hampshire fleece wool, silk and cashgora fibres with English cotton sit beneath the cover. Hand-tufting holds these fillings in place, which means they're less likely to shift or bunch over time.
Support system
A 5000 pocket spring system with ErgoZone 7 zoning uses thicker gauge wire and higher tension under your head, hips and feet, with softer zones at the shoulders and legs. In practice that means firmer support where your body is heaviest and more give where you need pressure relief.
Edge support
A metal rod runs along the top and bottom of the spring unit's edge, held with butterfly clips. This stiffens the border, so you get less of that roll-off feeling near the sides and better long-term durability.

Key benefits
- The classic shared size: At 4ft 6in x 6ft 3in, the UK double is the traditional couples' size, so it fits bedrooms where a UK king would crowd the walkways.
- Room for tables both sides: Allow at least 2.6m x 2.8m and most rooms will still take bedside tables on both sides, which matters when you each want a lamp and a phone charger.
- Zoned support for two: ErgoZone 7 zoning runs firmer springs under hips and softer ones at shoulders, so each of you gets pressure relief within your 67.5cm share.
- Edge support where sharing squeezes you: The metal rod edge with butterfly clips stiffens the border, useful in a UK double where one of you often sleeps nearer the side.
- Cooler for two bodies: Hampshire fleece wool, silk and cashgora breathe better than synthetic foams, which helps when two sleepers are warming the same 135cm of mattress.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit, both stocked everywhere at every price.
This size suits you if...
You share the bed every night, sleep fairly close together and want a well-made natural mattress in a size that leaves the rest of the room usable. It also suits a solo sleeper who likes space to spread out, or a guest room that regularly hosts visiting couples, provided the room offers at least 2.6m x 2.8m.
Consider another size if...
You and your partner both want real elbow room, since 67.5cm each is snug for restless sleepers. If the room stretches to 2.7m x 2.9m, we'd recommend the UK king instead: it gives 75cm each and an extra 10cm of length.

FAQ's
Is the Millbrook Wool Luxury 5000 in a UK double big enough for a couple?
For most couples, yes. You each get 67.5cm of width, which is comfortable if you sleep fairly close. The soft to medium feel lets you settle in rather than perch, and the zoned springs support each sleeper independently. If either of you moves around a lot at night, the UK king is the roomier option.
How much more space would the UK king give us than the UK double?
The UK king is 15cm wider and 10cm longer than the UK double, and gives 75cm each for two sharing, so the UK double gives 7.5cm less per person. The trade is room space: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Will a UK double Millbrook Wool Luxury 5000 leave room for bedside tables?
In most bedrooms, yes. The mattress is 135cm wide, and if your room meets our suggested minimum of 2.6m x 2.8m you should fit a table either side with walking space left over. Measure the wall the bed will sit against, add the width of both tables, and check before ordering.
Can I get the Millbrook Wool Luxury 5000 double up a narrow staircase?
Plan the route before delivery day. This is a heavy, hand-tufted pocket spring mattress at 32cm deep, so it won't fold or squash the way a rolled foam mattress does. At 135 x 190cm, tight turns on older terraced staircases or narrow new build landings can be a squeeze, so measure any pinch points first.
Where can I compare prices for the UK double Millbrook Wool Luxury 5000?
