Layer Details
- Sleep Surface. A naturally hypoallergenic 100% polyester fabric that's soft and gentle on the skin. A sensible choice if allergies tend to disturb your sleep.
- Comfort Breathe®. Silentnight states these fibres are 15x more breathable than standard memory foam, promoting airflow and regulating temperature. In practice, that means less overnight heat build-up, which hot sleepers will appreciate.
- 1000 Mirapocket Spring Unit. 1000 Mirapocket springs respond individually to your body's movements, which means support where you need it rather than a one-size-fits-all push back. The zoning helps keep your spine aligned.
- Protective Layer. This layer disperses pressure from the spring unit across the mattress. The aim is a longer usable life, as it stops the springs wearing through to the comfort layers above.
- Durable Case. A soft, durable outer case that holds everything together and helps the mattress stay comfortable over the years.

- Fits compact rooms: At 3ft wide it leaves floor space free for a desk, wardrobe or toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Grows with a child: The medium/firm tension gives supportive, level sleeping for growing backs, rather than the soft sink-in feel that can leave a light body poorly aligned.
- Cooler for teenagers: The Comfort Breathe fibre layer lets heat escape rather than trapping it, useful in small upstairs rooms that warm up quickly in summer.
- Kind to allergy sufferers: The sleep surface is naturally hypoallergenic and the mattress is dust mite resistant, a sensible feature for a child prone to sniffles.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any UK size, which keeps a guest room or first flat simple to run.
This size suits you if...
You're buying for a child or teenager's room where the bed has to share space with a desk and storage, you sleep alone and want the most floor space possible, or you're setting up a spare room that doubles as an office and needs a proper mattress rather than a fold-out.
Consider another size if...
You're an adult who sleeps sprawled or expects to share the bed, in which case we'd recommend the UK double instead. It's 45cm wider than the UK single, the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

What size is the Silentnight Comfort Breathe 1000 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits standard single bed frames, single fitted sheets and a standard single duvet without any hunting for unusual bedding.
Is the Silentnight Comfort Breathe 1000 UK single good for a child's bedroom?
Yes, with one caveat. The medium/firm tension supports a growing back well and the breathable fibre layer keeps a warm sleeper cooler, but a very light child may find it slightly firm at first. The hypoallergenic surface and dust mite resistance are genuine pluses for kids with allergies.
Will the Silentnight Comfort Breathe 1000 UK single work on a bunk or mid sleeper frame?
The UK single is the standard bunk and mid sleeper footprint, so the width and length will fit. The one thing to check is depth: this mattress is 24cm deep, and some raised frames set a maximum so the guard rail still sits high enough. Check your frame's guidance before buying.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk alongside the bed and open drawers or wardrobe doors. In a loft room with sloping ceilings, or a spare room that doubles as an office, the narrow 90cm footprint is exactly why this size gets chosen.
Should I get this mattress in a UK single or a UK small double?
For a child, a compact room or a guest bed, the UK single does the job and leaves more floor free. If an adult will sleep on it every night, the UK small double is 30cm wider and the same length, giving a solo sleeper welcome stretching room; we suggest at least 2.4m x 2.8m for the UK small double.
