Layer Details
- Memory Foam Comfort Layer. A responsive memory foam that gently moulds to your body's contours, which means it absorbs energy and eases built-up pressure at the hips and shoulders. You'll feel a slight cradling on the surface rather than a deep sink.
- Mirapocket Spring Support System. 1000 individually nested pocket springs (based on the king size, with the count varying pro-rata for other sizes) react independently to your body weight and movement. Silentnight states the zoned support is scientifically proven to help spinal alignment and posture.
Layer details from silentnight.co.uk product page, September 2026.
- Fits compact rooms: At 90cm wide it leaves floor space free, so a child's bed can share a room with a wardrobe, desk and toy storage without a squeeze.
- Suits raised frames: The 25cm depth sits comfortably in most bunk, cabin and mid-sleeper frames, where a deeper mattress can rise above the guard rail.
- Supportive for growing sleepers: The medium/firm Mirapocket springs give the zoned support Silentnight says helps spinal alignment, a sensible feel for children and teens who need structure rather than sink.
- Allergy-friendly for kids' rooms: The Purotex treatment, a natural probiotic that combats allergens, is genuinely useful in a child's bedroom where dust mites are a common trigger.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, which keeps the running costs of a guest bed or kid's bed low.
- Guest room ready: The memory foam top gives occasional visitors a slightly cradled surface, a step up from the basic mattresses spare beds often end up with.
This size suits you if...
You're buying for a child or teenager and want a supportive medium/firm mattress that will last through growth spurts, you need a mattress for a bunk, cabin or mid-sleeper frame where depth matters, or you're kitting out a spare room or a study that doubles as guest space. Allow at least 2.1m x 2.8m of floor space and a UK single fits almost any room.
Consider another size if...
You're an adult who sleeps with a partner, or you simply want more space than 90cm of width allows. 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 room for it.

Will the Silentnight Pocket Essentials 1000 UK single fit a bunk bed?
In most cases, yes. The UK single measures 90 x 190cm, the standard footprint for UK bunk, cabin and mid-sleeper frames, and at 25cm deep it should sit below the guard rail on most designs. Check your frame's maximum mattress depth before buying, as some bunks specify a shallower limit for the top bed.
Is the UK single Pocket Essentials 1000 a good choice for a child or teenager?
It's a sensible pick. The medium/firm Mirapocket support suits growing sleepers who need structure, and the Purotex allergen treatment helps in dustier kids' rooms. One caveat: lightweight side sleepers may find it a little too firm, as they won't press far into the memory foam layer. A heavier teen will get more from the surface than a small child.
What room size do you need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which is our own guidance rather than Silentnight's. That leaves room to walk round the bed and open drawers or a wardrobe. It's why the UK single works in box rooms, loft conversions with a narrow usable footprint, and spare rooms that double as an office.
Can I fit two singles in a shared kids' room instead of one bigger bed?
Often, yes, and it's usually the better arrangement for siblings. Each UK single is 90cm wide, and for comparison the UK single is 30cm narrower than the UK small double, so two singles plus a walkway need meaningfully more width than one bed. Measure the wall you'd put them against before committing.
