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
- Room to spread out alone: At 30cm wider than a UK single, this size lets a solo sleeper stretch across the soft comfort layers rather than perching in one spot.
- Fits where a double can't: It's 15cm narrower than a UK double, which is often the difference between a door that clears and one that doesn't in a box room or studio.
- Natural fillings in a small footprint: Hampshire fleece wool, silk and cashgora breathe well, so a small double squeezed against a wall in a snug room shouldn't turn stuffy.
- Easier to rotate at this width: This is a heavy, hand-tufted mattress, and the UK small double is slightly more manageable to turn in a tight space than the wider sizes.
- Edge support you'll actually use: The metal rod edge matters more at 120cm wide, because a solo sleeper on a smaller mattress uses the borders more often.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't take a full double, you're furnishing a loft conversion or box room where every centimetre of floor decides whether the layout works, or you're setting up a guest room that hosts the occasional couple rather than two people every night.
Consider another size if...
You share the bed most nights and want the soft feel without lying shoulder to shoulder. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of room for it.

FAQ's
Is the Millbrook Wool Luxury 5000 small double big enough for a couple?
For the odd night, yes. Two adults can share a UK small double comfortably enough for a weekend stay, and the soft, cushioned feel helps. For nightly sharing you'd feel the squeeze, and the ErgoZone 7 zoning works best when each sleeper has room to settle into their own position. Couples sharing every night should look at the UK double.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves walking space on at least one side and room for a wardrobe door to open. In a loft conversion, check the sloped ceiling too: you want standing headroom beside the bed, and the UK small double's narrower footprint often makes that possible where a double wouldn't.
Is the small double a good upgrade from a single for a teenager?
It's a sensible step. The UK small double is 30cm wider than a UK single but exactly the same length, so it adds sprawling room without eating into the floor space a teenager's room usually can't spare. The soft to medium feel suits lighter sleepers well, and the natural fillings should last through several years of growing.
How heavy is the Millbrook Wool Luxury 5000 in a small double to move?
Millbrook doesn't publish a weight for this size, but it's a hand-tufted natural mattress at 32cm deep, so expect a substantial lift. The UK small double is the more manageable end of the range, though we'd still suggest two people for rotating it, especially in a tight room where you can't swing it freely.
Where can I buy the Millbrook Wool Luxury 5000 in a UK small double?
Stock for this size moves around, so the simplest route is the live price table on this page, which updates as retailers change their listings. Check the retailer states 120 x 190cm before ordering: some list small doubles alongside EU sizes, and the two aren't interchangeable for frames or fitted sheets.
