Layer Details
- Tencel™ Lyocell sleep surface. A silky, soft-touch material woven to allow airflow, which means moisture is moved away from you rather than trapped at the surface. You should feel drier through the night as a result.
- British Wool Comfort Layer. Flexible, breathable wool from Cheviot sheep that keeps you cool in the summer and warm in the winter. It's a natural temperature regulator, doing quietly what synthetic layers often struggle with.
- Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam while offering the same pressure relief. In practice that means a cocooning, cushioned feel without the heat build-up foam can bring.
- Mirapocket® springs and mini pocket springs. 600 Mirapocket® springs work alongside 1000 mini pocket springs for additional comfort and increased breathability. Pocket springs move independently, which means less disturbance when a partner shifts position.

- A footprint for tight rooms: At 3ft x 6ft 3in, this size fits a child's bedroom alongside a wardrobe and desk, needing only 2.1m x 2.8m of floor space by our guidance.
- Wool for growing sleepers: The British wool layer regulates temperature naturally, which means a child or teen who runs hot at night should sleep drier and more settled.
- Foam free, naturally: Natural flame retardants and no foam layers make this an easy pick for parents who want fewer synthetics in a child's bed.
- Guest ready without compromise: In a spare room that doubles as an office, a single leaves working space intact while giving overnight guests proper pocket spring support.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so replacing bedding for a kid's room or student flat stays simple.
This size suits you if...
You're buying for a child or teenager and want natural materials rather than foam, you're a solo adult in a compact room or first flat where a wider bed would crowd the space, or you're kitting out a spare room that needs to keep working as an office between visits. The medium feel is forgiving enough for lighter bodies without feeling saggy for an adult guest.
Consider another size if...
You're an adult who sleeps alone but sprawls, or you share the bed even occasionally. We'd recommend the UK double instead: it's 45cm wider, the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

What size is the Silentnight British Wool 1600 UK single?
It measures 90 x 190cm, or 3ft x 6ft 3in. That's the standard UK single, so it fits ordinary single bed frames, and standard single sheets and a 135 x 200cm single duvet will fit without bunching or hanging short.
Is the UK single Silentnight British Wool 1600 a good choice for a child's room?
Yes, with one caveat. The wool and Tencel™ Lyocell surface handle temperature well for children who overheat at night, and the foam-free build appeals to parents avoiding synthetics. It is a grown-up mattress at a grown-up weight though, so it suits an older child or teen better than a toddler moving up from a cot bed.
Will the Silentnight British Wool 1600 single fit a bunk or mid sleeper?
The width matches standard bunk frames, but at 29cm this is a deep mattress, and many bunk and cabin beds specify a maximum depth so the guard rail still sits safely above the mattress surface. Check your frame's stated limit before buying; for younger children on a top bunk, a shallower mattress is often the safer fit.
How much floor space does a UK single need?
We suggest allowing at least 2.1m x 2.8m, which gives you room to walk alongside the bed and open drawers or a wardrobe. That makes the UK single workable in box rooms, loft conversions with a narrow usable footprint, and spare rooms where a desk shares the space.
Is the UK single big enough for an adult?
For one adult, yes: 90cm of width is the standard solo sleeping size, and the 1600 pocket springs support an adult's weight comfortably. If you're used to more room or tend to spread out, the UK double is 45cm wider and the same length, and needs a room of at least 2.6m x 2.8m.
