Layer Details
- Sleep surface. A naturally hypoallergenic fabric that feels soft against the skin. A gentle starting point for sensitive or allergy-prone sleepers.
- Airloft™ comfort layer. A foam alternative made from lightweight, open non-woven fibres, which the brand says is 18x more breathable. It mimics the feel of countless tiny springs, gently contouring to your body and spreading your weight evenly.
- 1000 Mini springs. A layer of 1,000 mini springs that respond to even slight movements, which means the surface adjusts as you shift in the night. They also add airflow through the middle of the mattress.
- Comfort Breathe®. Fibres described as 15x more breathable than standard memory foam. They promote airflow and help regulate temperature, a real plus if you tend to overheat.
- 600 Mirapocket spring unit. 600 pocket springs held in individual fabric pockets, each responding independently to your body. That gives you zoned support and better spinal alignment, and less disturbance from a restless partner.
- Protective layer. Disperses pressure from the spring unit across the mattress. In practice, this helps the mattress keep its feel for longer.
- Durable case. A soft but hard-wearing outer case designed to keep the mattress comfortable for years.

- Real room for one: At 120cm wide, the UK small double is 30cm wider than the UK single, so a solo adult can starfish without an elbow off the edge.
- Fits where a double can't: It's 15cm narrower than the UK double, which can be the difference between a bed and a squeeze in a box room or loft conversion.
- Cool at this size too: The Airloft fibres and 1,000 mini springs let air move through the mattress, useful for a hot solo sleeper who tends to gravitate across the whole surface.
- Medium/soft suits a lone sleeper: With nobody else's weight on the springs, the softer-than-medium feel gives gentle give at shoulders and hips for side sleepers.
- Sensible for guest rooms: The 600 Mirapocket springs respond independently, so two occasional guests sharing 120cm won't roll into each other every time one turns.
This size suits you if...
You sleep alone, run warm, and have outgrown a UK single but your room can't take a full double. Or you're furnishing a guest room, holiday let or small second bedroom where couples stay for the odd night rather than every night. It also suits a teenager moving up from a single in a room where floor space still matters.
Consider another size if...
You share the bed every night, because 120cm is a slightly tight long-term width for two adults. We'd recommend the UK double instead, which is 15cm wider; allow a room of at least 2.6m x 2.8m for it.

What size is the Silentnight Comfort Breathe Plus 1600 small double?
It measures 120 x 190cm, or 4ft x 6ft 3in. That's the standard UK small double footprint, so 4ft frames and small double fitted sheets will fit without any hunting around. The mattress itself is 28cm deep, so choose deep fitted sheets rather than standard ones.
Will the small double Comfort Breathe Plus 1600 fit in a box room?
Usually, yes, and that's a big part of this size's appeal. We suggest a room of at least 2.4m x 2.8m, which leaves enough space to walk round the bed and open the door. Measure with wardrobes and radiators in mind, because it's the walkway that gets tight, rather than the bed itself.
Is the small double big enough for a couple on this mattress?
For occasional nights, yes. The 600 Mirapocket springs move independently, so one person turning won't shake the other awake, and the breathable build helps when two bodies warm the bed. For nightly sharing, 120cm is a little snug, and the UK double gives you 15cm more width.
Should I choose the small double or the double in the Comfort Breathe Plus 1600?
It comes down to who sleeps in it and how much room you have. The UK small double is 15cm narrower than the UK double, both are the same length. Sleeping solo in a compact room, take the small double. Sharing every night, the UK double is the better buy if your room allows at least 2.6m x 2.8m.
