Layer Details
Quilted sleep surface
A soft quilted top with a breathable airflow border, which means heat can escape around the edges rather than building up. It's the layer your child actually feels, gently cushioned rather than plush.
British Wool
A layer of premium British Wool, a naturally breathable fibre that helps regulate temperature. In practice, that means a cooler, fresher feel through the night for warm sleepers.
Pocket springs
600 individual Mirapocket springs that respond to your child's posture separately, so they can shift position freely and stay supported. This gives a more tailored feel than a basic open-coil kids' mattress.

Key benefits
- Fits the frame your child already has: At 90 x 190cm it matches standard UK single bed frames, bunks, cabin beds and mid sleepers, so an upgrade doesn't mean new furniture.
- Leaves room for everything else: A child's bedroom has to hold a wardrobe, a desk and the toy overflow; a 3ft-wide mattress keeps floor space free for all of it.
- Works in shared rooms: Two UK singles plus a walkway fit in most sibling-shared bedrooms, where anything wider quickly becomes a squeeze.
- Breathable where it matters: The British Wool layer helps a warm-sleeping child stay comfortable, useful in a compact room where air doesn't circulate as freely.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or younger teen moving up from a cot bed or replacing a tired mattress, you want a foam-free, natural build in the standard 90 x 190cm children's size, or you're fitting a bunk, cabin or mid-sleeper frame that takes a UK single. It also suits a compact room where every centimetre of floor space is contested.
Consider another size if...
Your child is an older teen who'd appreciate more width, or the bed will regularly sleep an adult. This mattress only comes in a UK single, so you'd need a different mattress in a UK small double or larger.

FAQ's
Will the Silentnight Starry Natural fit a bunk bed or mid sleeper?
Yes, the UK single is the standard size for bunks, cabin beds and mid sleepers, so the 90 x 190cm footprint should match your frame. Do check the height, though: at 27cm this is a reasonably deep kids' mattress, and raised frames often specify a maximum depth so the guardrail still does its job.
How much floor space does a UK single need in a child's room?
We suggest allowing at least 2.1m x 2.8m. That gives you the mattress plus enough clearance to open drawers and walk around one side. In practice most children's rooms manage this easily, which is part of why the UK single remains the default size for kids' beds.
Can two Silentnight Starry Natural singles fit in a shared kids' room?
Often, yes. Each UK single is 90cm wide, so two beds against opposite walls with a walkway between them work in most average children's rooms. Measure your wall lengths against the 190cm mattress length first, and remember each child gets the same 600 pocket springs, so one restless sleeper won't disturb the other bed.
Is a UK single big enough for a teenager?
For most younger teens, yes. At 90 x 190cm it's the size the majority of UK teenagers sleep on, and this mattress is designed for growing bodies. Taller or older teens sometimes prefer the extra 30cm of width a UK small double offers, but this mattress isn't made in that size, so you'd be choosing a different model.
What bedding do I need for this mattress?
Standard UK single bedding fits: single fitted sheets sized for 90 x 190cm and a single duvet at 135 x 200cm. That's the cheapest and most widely stocked bedding of any UK size, handy when a child's sheets need changing more often than an adult's. The 27cm depth sits within what most standard fitted sheets accommodate.
