Layer Details
- Memory Foam. A memory foam layer that moulds to your body, which means pressure is eased from muscles and joints as you settle in. Expect a gentle cradle rather than a deep sink, given the firm overall feel.
- Mirapocket Springs. 1400 Mirapocket springs sit beneath the foam, each responding independently to your movement. In practice that means targeted support along your spine and less motion transfer across the bed.

- Fits a busy child's room: At 90cm wide it leaves floor space for a desk, wardrobe and toy storage in a bedroom that has to do several jobs at once.
- Firm support for growing sleepers: The firm rating gives children and teens a flat, supportive surface rather than a soft one they sink into as they grow.
- Works on raised frames: At 25cm deep it sits within the depth most bunk and mid-sleeper frames allow, though check your frame's maximum against the guard rail before buying.
- Two can fit where one double won't: Siblings sharing a room can have a UK single each with a walkway between, which a wider bed would rule out.
- Guest-ready without dominating the room: In a spare room that doubles as an office, this size hosts an adult guest comfortably while leaving space for a desk the rest of the year.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and both are the most widely stocked and least expensive of any UK size.
This size suits you if...
You're buying for a child or teenager who needs proper support on a compact footprint, you're furnishing a spare room or student flat where the frame is provided and space is tight, or you sleep alone and want a firm pocket-sprung hybrid without paying for width you won't use. Allow at least 2.1m x 2.8m of floor space and it should fit comfortably.
Consider another size if...
You're an adult who sleeps alone but likes to spread out, or you share the bed even occasionally. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Is the Silentnight Memory 1400 UK single a good choice for a child's bed?
For older children and teenagers, yes. The firm feel gives a supportive, flat surface, and the 90 x 190cm footprint suits a bedroom that also has to hold a desk and wardrobe. Very lightweight side sleepers may find the shoulder a little solid, so it's less suited to a child who sleeps mostly on their side.
Will the UK single Silentnight Memory 1400 fit a bunk or mid sleeper?
The UK single is the standard bunk and mid-sleeper size at 90 x 190cm, so the footprint will fit. The mattress is 25cm deep, which works with many raised frames, but some bunks specify a shallower maximum so the guard rail stays effective. Check your frame's stated limit before ordering.
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 wardrobe doors. That makes the UK single a realistic fit for box rooms, loft conversions with a narrow usable strip under the slope, and children's rooms where the bed shares space with storage.
Is a UK single big enough for adult guests?
For occasional stays, yes. At 3ft x 6ft 3in it takes a single adult comfortably, and the firm feel with 1400 pocket springs offers more support than the fold-out beds many spare rooms rely on. A guest who is used to a double at home will notice the narrower width, but for a few nights it works well.
Should I buy the UK single or the UK small double for one adult?
It depends on the room and the sleeper. The UK single is 30cm narrower than the UK small double, and the two are the same length, so the question is width. A restless adult sleeper will appreciate the extra room of the UK small double if the bedroom offers at least 2.4m x 2.8m; otherwise the UK single keeps the floor usable.
