- Made for small rooms: At 3ft x 6ft 3in, this UK single leaves floor space for a desk, wardrobe or toy storage in even a compact child's bedroom.
- Light enough to flip: The double-sided design rewards regular turning, and in a UK single that job is manageable for one person rather than a two-person struggle.
- Proper springs for growing sleepers: The 600 zoned Mirapocket springs spread weight evenly, which means a child or teen gets real spinal support rather than a slab of foam.
- Reassuring for allergy-prone kids: It's hypoallergenic, dust mite resistant and Allergy UK approved, a sensible feature for a child's room where dust builds up quickly.
- Guest ready without fuss: For a spare room that doubles as an office, a medium-feel pocket spring single suits occasional visitors without taking over the room.
This size suits you if...
You're furnishing a child's or teenager's room and want proper pocket springs rather than a basic foam slab, you're setting up a spare room or student flat where the bed sees occasional use, or you sleep alone in a compact bedroom and would rather keep floor space for a desk or wardrobe than fill the room with mattress.
Consider another size if...
You're an adult sharing the bed, or you sleep alone and want room to stretch out. We'd recommend the UK double instead: it's 45cm wider than the UK single and the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

What size is the Silentnight Essentials Pocket 600 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK single, so it fits any standard single bed frame, divan or slatted base without any guesswork. Every size of this mattress is 26cm deep, so allow for that when choosing a fitted sheet.
Will the Silentnight Essentials Pocket 600 UK single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk, cabin and mid sleeper frames. The one thing to check is depth: this mattress is 26cm deep, and many raised frames specify a maximum so the guard rail still sits safely above the mattress. Measure your frame's stated limit before ordering.
Is the UK single Silentnight Essentials Pocket 600 a good choice for a child's room?
It's well suited. The zoned pocket springs support a growing back, the medium feel works for lighter bodies, and the Allergy UK approval is welcome in a room where dust gathers. Being double sided, you can flip it as your child grows heavier, which helps it wear evenly through the school years.
How much room do you 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 round the bed and open drawers or wardrobe doors. That modest footprint is the appeal here: the UK single fits box rooms, loft conversions with a narrow flat ceiling, and spare rooms that also hold a desk.
Is the UK single big enough for an adult?
For one adult sleeping alone, yes: it's the standard UK one-person size, and the 600 pocket springs support an average-weight adult comfortably. If you like to spread out, or a partner ever stays, the UK double is 45cm wider and the same length. We suggest at least 2.6m x 2.8m of floor space for the UK double.
