Layer Details
- Damask cover. A finely woven damask cover that is soft to the touch. Damask is a durable fabric, so it should hold up well over years of use.
- Natural fibre comfort layer. A blend of Hampshire wool, silk and cashgora gives a plush, cosy surface feel. Wool and silk are naturally breathable, which helps with temperature regulation.
- Cotton blend comfort layer. A cotton and polyester blend adds further breathability. In practice, this means less heat building up around you overnight.
- Graphite latex. A layer of graphite latex foam that shapes around your body while keeping a natural bounce. It is highly adaptive, so it contours without the slow, stuck-in feel some foams have.
- Pocket spring support core. A core of 1,000 pocket springs with a 7-zone ergonomic design that adapts to your movement. Zoning means different areas of the mattress respond differently, supporting hips and shoulders where they need it.
- Mini springs. 3,000 mini springs sit within the mattress to add bounce and increase comfort. Combined with the pocket spring core, that brings the total to 4,000 springs.
- Ultra Edge support. A rod wire frame with butterfly clips forms Millbrook's Ultra Edge system. This firms up the perimeter, so you can sleep near the edge without feeling you might roll off.

- Fits a genuinely small room: At 90 x 190cm (3ft x 6ft 3in), it leaves floor space free in a child's bedroom that's already competing with a desk, wardrobe and toy storage.
- Edge support matters more at this width: On a 90cm mattress you sleep closer to the edge by default, so Millbrook's Ultra Edge rod wire frame keeps the perimeter usable rather than saggy.
- Natural fillings for growing sleepers: Wool, silk and cashgora regulate temperature naturally, which suits children and teens who run warm at night.
- Full support in a one-person size: You get the same 4,000 springs and 7-zone design as the larger sizes, so a solo sleeper isn't getting a cut-down version.
- A guest bed people remember kindly: Latex bounce and a medium firm feel make this a spare-room single that visitors won't quietly complain about.
This size suits you if...
You're furnishing a child's or teenager's room where every centimetre of floor counts, you sleep alone and would rather spend on quality than width, or you want a guest single that feels like a proper bed rather than a spare-room compromise. It also suits a spare room doubling as an office, where a UK single leaves space for a desk that larger sizes would swallow.
Consider another size if...
You're an adult who spreads out in the night, or you share the bed even occasionally. We'd recommend the UK small double instead: it's 30cm wider, the same length, and needs a room of at least 2.4m x 2.8m.

What size is the Millbrook Wool Luxury Latex 4000 in a UK single?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in. We suggest allowing at least 2.1m x 2.8m of floor space, which makes it a realistic fit for box rooms, lofts with a narrow footprint and children's bedrooms where the bed shares space with a desk and wardrobe.
Is the Millbrook Wool Luxury Latex 4000 single suitable for a bunk or mid sleeper?
Probably not. At 32cm deep, it's a tall mattress, and raised frames need the mattress to sit safely below the guard rail. Measure from the base to the top of the rail before buying; on most bunks and mid sleepers a shallower single is the safer choice. On a standard bed frame or divan, the depth is no problem.
Is this mattress in a UK single a good choice for a child or teenager?
Yes, with one caveat. The wool, silk and cashgora fillings breathe well, which helps children who overheat at night, and the medium firm feel supports a growing body without being hard. The caveat is price: it's a premium single, so it makes most sense for a teenager who'll use it for years rather than a toddler about to size up.
Should one adult choose the UK single or the UK small double?
It comes down to room size and how you sleep. The UK single is 30cm narrower than the UK small double, and both are the same length. If you sleep still and your room is tight, the single is fine. If you spread out and can allow at least 2.4m x 2.8m of floor space, the UK small double is the more comfortable long-term buy.
