Layer Details
- Belgian damask cover. A breathable Belgian damask fabric tops the mattress. It lets air move through the sleep surface rather than sealing heat in.
- Wool layer. Wool fillings give a soft, cushioned feel at the surface, which means the firm springs beneath don't feel harsh against your body. It's a natural choice if you prefer a traditional mattress over synthetic foams.
- eOlus fibres. These fibres offer resilient body support while letting air and moisture pass through easily. Unlike foam, they don't hold onto heat or sweat, yet they still give a soft, foam-like feel.
- ReActive 7-turn pocket springs. Each spring has seven turns and works independently, sensing the comfort and support needs of you and your partner and spreading downward pressure smoothly. In practice, that means full spinal support and less disturbance when one of you moves.

- Real space for one: At 30cm wider than the UK single, it lets a solo sleeper stretch across the firm pocket sprung surface without the frame dominating the room.
- Fits compact bedrooms: It's 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Firm support in a smaller footprint: You get the same ReActive 7-turn pocket springs as the larger sizes, so choosing a smaller bed doesn't mean compromising on support.
- Cooler solo sleeping: Wool and breathable eOlus fibres let heat escape, useful in small rooms and loft conversions where warm air tends to gather.
- Easy bedding and frames: The 4ft size is a standard UK width, so small double fitted sheets and frames are straightforward to find.
This size suits you if...
You sleep alone and have outgrown a single but can't spare the floor space a standard double takes, or your box room, loft conversion or studio makes every centimetre of width count, or you're furnishing a guest room where couples stay occasionally rather than nightly. The firm feel suits back and front sleepers best.
Consider another size if...
You share the bed every night, because two adults on 120cm of firm mattress will feel each other's edges. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room space.

Is a small double Hypnos Wool Ortho big enough for a couple?
For occasional nights, yes. The independent pocket springs reduce disturbance when one of you moves, and at 120cm wide there's room for two for a guest room stay. For every night, most couples find it tight, and the firm surface doesn't invite cosying into each other's space. The UK double is 15cm wider.
What are the dimensions of the Hypnos Wool Ortho small double?
It measures 120 x 190cm, or 4ft x 6ft 3in. That's 30cm wider than the UK single and the same length, so it upgrades a solo sleeper's width without needing a longer room. Standard small double fitted sheets fit, and a standard double duvet works well on top.
What room size do I need for a small double mattress?
We suggest at least 2.4m x 2.8m, which leaves enough space to walk around the bed and open drawers or a wardrobe. That makes this size a sensible choice for box rooms, studio flats and loft conversions where a standard double, needing at least 2.6m x 2.8m by our guidance, would crowd the space.
Is the small double a good choice for a teenager?
Often, yes. A teenager who has outgrown a single gets 30cm of extra width without losing the floor space a full double takes. The firm feel gives growing backs solid support, although a lighter side sleeper may find it a little unyielding, so factor in how they usually sleep before deciding.
Should I size up to the UK double instead?
If the room takes it and you share the bed regularly, probably. The UK small double is 15cm narrower than the UK double and the two are the same length, and we suggest at least 2.6m x 2.8m for the UK double. Sleeping solo in a compact room, the small double is the better fit.
