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.

- Fits a compact bedroom: At 90cm wide it leaves floor space free in a small room, so a desk or wardrobe can sit alongside without the bed dominating.
- A softer feel for lighter sleepers: The soft to medium surface gives teenagers and lighter adults some sink, which means shoulders and hips settle in rather than perching on top.
- Natural fillings in a spare room: Hampshire fleece wool, silk and cashgora breathe well, so a guest bed stays comfortable for visitors whatever the season.
- Stable edges in a narrow bed: A metal rod border with butterfly clips stiffens the sides, useful on a 90cm width where you sleep closer to the edge.
- A long-term buy, sized down: The hand-tufted, 32cm-deep build is a real spend for a single, but it should outlast cheaper children's mattresses considerably.
This size suits you if...
You sleep alone and want a genuinely well-made mattress rather than a budget single, you're buying for a teenager who runs warm at night and would benefit from breathable natural fillings, or you're furnishing a spare room and want guests to sleep on something better than the usual afterthought.
Consider another size if...
You share the bed, or you're a single adult who spreads out and finds 90cm restrictive. We'd recommend the UK double instead: it's 45cm wider, gives 67.5cm each for two sharing, and needs a room of at least 2.6m x 2.8m.

What size is the Millbrook Wool Luxury 5000 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits ordinary single bed frames, and standard single sheets and a single duvet fit without adjustment. We suggest a room of at least 2.1m x 2.8m to leave walking space around it.
Will the UK single Millbrook Wool Luxury 5000 work on a bunk or mid sleeper?
The width matches standard bunk frames, but the depth is the problem. At 32cm this is a tall, substantial mattress, and most bunk and mid-sleeper frames need a shallower one so the guard rail still does its job. Check your frame's maximum mattress depth before buying; for many raised frames this one will sit too high.
Is the Millbrook Wool Luxury 5000 single a good choice for a child's room?
For an older child or teenager, yes, with a caveat. The soft to medium feel suits lighter bodies, and the breathable wool and cotton fillings help warm sleepers. It's a premium spend for a child's bed, though, so it makes most sense if you want a mattress that lasts through the teenage years rather than a short-term buy.
Is a single big enough for an adult on this mattress?
For most single adults, yes. At 90cm wide you have the whole surface to yourself, and the zoned springs support you the same as in larger sizes. If you're tall, note the 190cm length: sizing up to the UK king adds 10cm of length, though that's a much bigger footprint overall.
Is the UK single easy to move and rotate?
Easier than the larger sizes, but this is still a heavy, hand-tufted natural mattress at 32cm deep, so rotating it is a two-person job done comfortably, a slightly awkward one done alone. That's worth weighing up if it's going in a teenager's room or a loft conversion with a narrow staircase.
