Cover
An unbleached, chemical-free cotton cover in Belgian damask, which means a soft, breathable sleeping surface without harsh treatments. Damask is a tightly woven fabric that wears well over time.
Comfort fillings: British wool
Insulating British wool cushions the whole body, which means gentle pressure relief rather than the sink-in feel of memory foam. Wool also helps keep the surface temperate.
Comfort fillings: cotton
Cotton wicks away excess moisture and works alongside the wool to regulate temperature. In practice, that means a drier, more comfortable feel in both summer and winter.
Comfort fillings: Solotex and eOlus fibres
Recycled Solotex and eOlus fibres add to the cushioning while promoting airflow. That extra breathability matters most if you tend to overheat at night.
Support system: ReActive pocket springs
A core of ReActive 8-turn pocket springs supports key areas of the body. Each turn lets the spring react faster to your movements, which means the mattress adjusts as you change position rather than lagging behind.

Key benefits
- Real width for one sleeper: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a solo adult can stretch out properly every night.
- Fits rooms a double crowds: It's 15cm narrower than a UK double, which can be the difference between a door that clears the bed frame and one that doesn't.
- Firm support in a compact footprint: The ReActive 8-turn pocket springs respond as you shift position, so a solo sleeper who moves around still feels supported edge to edge.
- Natural fillings that breathe: British wool and cotton regulate temperature, useful in the smaller, sometimes stuffier rooms where a 4ft bed usually ends up.
- Copes with occasional sharing: Two adults can manage a night or two at 120cm wide, which makes it a sensible guest room pick where nobody sleeps in it nightly.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't absorb a full double, you're furnishing a guest room where couples stay occasionally rather than every night, or you're kitting out a box room, studio or small second bedroom in a rental and want quality fillings in a footprint the space can actually take.
Consider another size if...
You share the bed every night, or your room comfortably exceeds our suggested 2.4m x 2.8m minimum. We'd recommend the UK double instead: it's 15cm wider, the same length, and needs a room of at least 2.6m x 2.8m.

FAQ's
What size is the Hypnos Majesty Ortho Sublime small double?
The UK small double measures 120 x 190cm, which is 4ft x 6ft 3in. That's the same length as a UK single and a UK double, so headboard-to-footboard it takes up no more of the room than either; the width is what sits between them.
What room size do I need for a small double Hypnos Majesty Ortho Sublime?
We suggest a room of at least 2.4m x 2.8m. That allows walking space along the side and room to open drawers or a door. In a loft conversion or box room, check where the ceiling slopes as well as the floor area, since you'll want standing room beside the bed.
Can a couple sleep on the Hypnos Majesty Ortho Sublime small double?
For occasional nights, yes, and the firm feel plus responsive pocket springs mean one person turning over is less likely to disturb the other. At 120cm wide it's a squeeze for nightly sharing, though, so couples using it as their main bed should consider a UK double or UK king.
Is the small double or the UK double better for a small bedroom?
The UK small double is 15cm narrower than the UK double and the same length, so it suits rooms where every centimetre of width matters. We suggest at least 2.4m x 2.8m for the UK small double and 2.6m x 2.8m for the UK double; measure your room against both before deciding.
Will the small double Hypnos Majesty Ortho Sublime fit up narrow stairs?
It arrives flat rather than rolled and boxed, which suits its natural fillings but means you're moving a full 120 x 190cm mattress in one piece. Measure your stairwell, landings and door frames before ordering, particularly for a loft conversion or a flat with tight turns on the stairs.
