Key benefits
- Fits almost any room: At 90cm wide it slots into box rooms, loft conversions with a narrow footprint under the slope, and spare rooms that double as an office.
- Firm support for growing sleepers: The firmer feel holds a back or front sleeper level rather than letting them sink, which many parents prefer for teenagers moving up from a childhood bed.
- Full pocket spring count in a small size: You still get individual springs shaping to one body, so a single sleeper feels the same contouring a couple would on a larger size.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and they're the most widely stocked and least expensive bedding of any UK size.
- Practical for guest and student rooms: A sensible choice where the frame is already provided, in halls, first flats or a spare room set up with two beds rather than one.
This size suits you if...
You sleep alone and prefer a bed that supports you firmly rather than cradles you, you're buying for a teenager who needs proper support in a room where the bed competes with a desk and wardrobe, or you're furnishing a guest room or student flat where 90cm of width keeps floor space free. Allow at least 2.1m x 2.8m of floor space.
Consider another size if...
You're an adult who finds a 90cm width restrictive, or you want space to stretch out. The UK small double is 30cm wider at the same length; we suggest a room of at least 2.4m x 2.8m for it.

FAQ's
Is a UK single big enough for an adult?
For most adults, yes, though it's snug. The UK single is 90cm wide and 190cm long, which suits one person sleeping fairly still. If you spread out or change position a lot, the UK small double gives you 30cm more width at the same length, provided your room allows at least 2.4m x 2.8m.
Will the single Silentnight Pocket 1400 fit a bunk or mid sleeper?
The width and length match standard UK bunk and mid-sleeper frames, which are built around 90 x 190cm. The thing to check is depth: raised frames set a maximum mattress height for the guard rail to work safely, so measure your frame's limit and check the mattress depth against it before buying.
Is the Silentnight Pocket 1400 Ortho too firm for a child?
It depends on the child. Silentnight describes this as a firmer mattress, which suits back and front sleepers and heavier teens well. A lightweight child who sleeps on their side may find it a little unforgiving at the shoulder and hip, so a softer mattress could be the kinder choice for them.
What room size do you need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which leaves room to walk around the bed and open a wardrobe. That makes it workable in a child's room shared with toy storage and a desk, or in a spare room that also serves as an office.
What's the difference between the UK single and UK double in this mattress?
The UK single is 45cm narrower than the UK double, and the two are the same length. The single suits one sleeper in a compact room; the double gives a solo adult generous space or fits a couple, and we suggest a room of at least 2.6m x 2.8m for it.
