Layer Details
- EcoComfort Fibres™. A breathable comfort layer designed for cooler sleep. It sits at the top of the mattress, which means less heat trapped around your child overnight.
- Mirapocket® springs. 600 Mirapocket® springs provide full body support, with each pocket spring adjusting individually to body weight. The zoned design means support goes where it's needed as your child moves around.
Layer details from silentnight.co.uk product page, September 2026.
- Made for the size it comes in: This is a children's mattress in the classic children's size, so the 600 Mirapocket® springs are matched to the lighter bodies a UK single usually carries.
- Fits raised frames: At 21.5cm deep, it sits within the depth limits most bunk beds, cabin beds and mid sleepers ask for, though check your frame's guard rail height first.
- Leaves room to play: A 90cm wide footprint keeps floor space free for a desk, wardrobe and toy storage, the usual squeeze in a child's bedroom.
- Works for two beds: Where siblings share a room, two UK singles plus a walkway fit in spaces that a larger bed would swallow whole.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and they're the most widely stocked bedding of any UK size.
This size suits you if...
You're buying a first proper mattress for a child moving out of a cot bed, or replacing a tired mattress on a bunk, cabin or mid-sleeper frame. It also suits a compact bedroom where the bed shares space with a desk and wardrobe, or siblings sharing a room with two beds side by side.
Consider another size if...
You're shopping for an older teen ready for more width, an adult, or a guest room that hosts couples. This mattress only comes in a UK single and is built for children's lighter bodies, so a different mattress in a larger size would suit you better.

What size is the Silentnight Healthy Growth Dreamer kids mattress?
It comes in one size only: a UK single, measuring 90 x 190cm, or 3ft x 6ft 3in. That's the standard UK one-person size and the default for children's beds, so it fits most kids' frames, bunk beds and mid sleepers without any special measuring.
Will the Silentnight Healthy Growth Dreamer UK single fit a bunk or mid-sleeper frame?
In footprint, yes: 90 x 190cm is the standard frame size for bunks, cabins and mid sleepers. At 21.5cm deep it also sits within the depth limit most raised frames specify, but do check your frame's maximum mattress depth against the guard rail before buying.
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 leaves enough clearance to walk round the bed and open drawers, with room left over for a wardrobe or desk. In a shared room, two UK singles with a walkway between them will need noticeably more width.
What bedding fits the Healthy Growth Dreamer in a UK single?
Standard UK single fitted sheets and a single duvet, which measures 135 x 200cm. These are the cheapest and most widely available bedding of any size, a small ongoing saving that adds up over the years a child uses the mattress.
Is a UK single big enough to last my child into their teens?
For most children, yes. At 90 x 190cm it's the same length as a UK double, so height is rarely the problem. Taller or older teens may eventually want more width, and since this mattress only comes in a UK single, that would mean a different mattress at that point.
