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.

- Real space for one: At 30cm wider than the UK single, it suits a solo sleeper who has outgrown a narrower bed but sleeps alone most nights.
- Natural fillings in a compact footprint: You get the Hampshire wool, silk and cashgora layers in a size that fits box rooms and loft conversions.
- Edge support matters more at 4ft: Millbrook's Ultra Edge rod wire frame keeps the perimeter usable, which counts when two occasionally share a narrower mattress.
- Latex bounce in a smaller bed: The graphite latex layer makes changing position easy, welcome when there's slightly less width to roll around in.
- Medium firm feel for varied guests: A medium firm surface with a plush wool top suits a range of visitors if this size is destined for a guest room.
This size suits you if...
You sleep alone and want more room than a UK single without giving up walking space, your bedroom or loft conversion can take a 120cm width but a standard double would crowd it, or you're furnishing a guest room where couples stay for the odd weekend rather than every night.
Consider another size if...
You share the bed every night, because 120cm is snug for two adults long term. We'd recommend the UK double instead, which is 15cm wider, gives 67.5cm each and needs a room of at least 2.6m x 2.8m.

Is a small double big enough for two on this Millbrook mattress?
For occasional nights, yes. The medium firm feel and the Ultra Edge support keep the sides usable, so neither sleeper feels perched. For every night sharing, 120cm is tight; the UK double gives 67.5cm each and the UK king gives 75cm each, which most couples find noticeably more comfortable.
What room size do I need for the small double Millbrook Wool Luxury Latex 4000?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers. The mattress itself is 120 x 190cm, so measure your usable floor rather than the room's listed dimensions, especially in loft conversions where sloping ceilings eat into standing room.
Is the small double a good guest room choice for this mattress?
It suits a guest room well. Solo visitors get plenty of space, couples can share for a weekend, and the 15cm saved against a UK double often decides whether wardrobes still fit. The wool and latex layers are a premium spec for occasional use, but guests will sleep well on them.
What bedding does the Millbrook small double take?
You'll need small double, or 4ft, fitted sheets, and check they're deep enough for this 32cm mattress, as standard depth sheets can pop off a taller hybrid. A standard double duvet works fine on the 120cm width, with a little overhang each side.
Where can I buy this mattress in a small double?
Availability changes, so the most reliable answer is the live comparison table on this page, which is updated as retailers change their prices and stock. It's a standard 4ft UK size, so frames and bases are easy to find separately if you need one too.
