Layer Details
- Sized for growing sleepers: At 190cm long the UK single matches the UK small double for length, so a child can keep this mattress well into their teens.
- Fits a compact bedroom: A 90cm wide mattress leaves floor space for a desk, wardrobe and toy storage in rooms where every metre is contested.
- Works for sharing siblings: Two UK singles plus a walkway fit in most shared children's rooms, which a larger bed simply wouldn't allow.
- Medium firm support for one: Consistent medium firm tension holds back and front sleepers steady, useful for children who need support rather than sink.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and they're the most widely stocked bedding of any size.
This size suits you if...
You're buying for a child or teenager moving up from a cot bed or outgrowing a small single, you need a supportive medium firm mattress for a spare room that doubles as an office, or you're kitting out a student room or first flat where the frame is provided and the mattress isn't.
Consider another size if...
You're an adult who shares the bed even occasionally, or you simply want more room to stretch out. We'd recommend the UK small double instead: it's 30cm wider, the same length, and needs a room of at least 2.4m x 2.8m.

Will the Silentnight Healthy Growth UK single fit a bunk bed or mid sleeper?
The footprint matches standard UK bunk and mid sleeper frames at 90 x 190cm. Raised frames also limit mattress depth for safety, though, and Silentnight doesn't publish a depth for this mattress, so check your frame's maximum against the retailer listing before you order.
What room size do I need for the Healthy Growth in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk around the bed and open drawers or wardrobe doors. That's our own guidance rather than Silentnight's, and it makes the UK single one of the few sizes that works under a loft conversion's sloping ceiling.
Is a UK single Healthy Growth big enough for a teenager?
For most, yes. At 190cm long it's the same length as the UK small double, so a teenager won't outgrow it lengthways. The 90cm width suits one sleeper comfortably, and the medium firm tension is designed with growing bodies in mind, although a particularly tall or broad teen may prefer sizing up.
Should I buy the Healthy Growth in a single or a small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length. For a child's room, or anywhere two beds need to share the space, the UK single is the practical choice. For an older teen or a single adult with the room to spare, the extra width is a genuine comfort upgrade.
Is the single Healthy Growth a good spare room mattress?
It's a sensible pick for a spare room, particularly one doubling as an office where a wider bed would crowd the desk. Medium firm tension suits most back and front sleepers, so occasional guests should find it comfortable, though very lightweight side sleepers may find it slightly solid.
