Layer Details
- Fits where space is tight: At 90 x 190cm it slots into rooms where the bed competes with a desk, wardrobe and toy boxes, and we suggest allowing at least 2.1m x 2.8m of floor space.
- Quiet in shared kids' rooms: Being foam rather than sprung, it has no coils to creak, which helps when two siblings sleep a walkway apart and one is a fidgeter.
- A sensible spare room spend: The low price suits a guest bed or a study that doubles as sleeping space, where paying for premium construction rarely pays off.
- Easy bedding to buy: Standard single sheets and a single duvet (135 x 200cm) fit, and both are the cheapest and easiest bedding sizes to find in UK shops.
- Backed by a guarantee: A 5-year manufacturer guarantee is reassuring at this price, particularly for a child's mattress that will take a few years of hard use.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, kitting out a guest room or student flat where the frame is provided but the mattress isn't, or you sleep alone in a compact room where a wider bed would swallow the floor space.
Consider another size if...
You're an adult who sleeps on their back with arms spread, or you share the bed. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Is the Silentnight Comfortable Foam Sleep Mattress single good for a child's room?
It's a reasonable fit. The all-foam build is quiet, the price is low enough that a few years of jumping and spills won't sting, and the 5-year guarantee covers manufacturing faults. Silentnight doesn't publish an age recommendation, so check the brand's own guidance for very young children before buying.
Will this single mattress fit a bunk bed or mid sleeper?
The 90 x 190cm footprint is the standard size for UK bunk beds, cabin beds and mid sleepers, so the width and length should match. Raised frames often have a maximum mattress depth for the guard rail, and Silentnight doesn't publish a depth for this mattress, so check your frame's limit against the retailer listing first.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which leaves room to walk around and open drawers. That makes the UK single a practical choice for box rooms, loft conversions with a narrow usable footprint, and spare rooms that also hold a desk. Two singles for siblings need extra width for a walkway between them.
Is the UK single big enough for an adult?
At 3ft wide it works for a single adult who sleeps fairly still, and it's the usual size in student rooms and first flats. If you're broad-shouldered or move around a lot at night, the UK small double is 30cm wider and the same length, which makes a noticeable difference for solo sleepers.
