Layer Details
EcoComfort Fibres™
A breathable fibre comfort layer that sits at the top of the mattress. It allows air to move through, which means a cooler, less clammy feel for warm sleepers.
Mirapocket® springs
A base of 600 Mirapocket® springs, each moving independently to give full body support. The zoned design, which Silentnight says is scientifically proven to improve spinal alignment and posture, firms up where your child's body needs it most.

Key benefits
- Made for children's rooms: At 90cm wide, it leaves space in a child's bedroom for the desk, wardrobe and toy storage that always end up competing with the bed.
- Suits raised frames: The 90 x 190cm footprint matches standard bunk and mid-sleeper frames, and the slimmer 21.5cm depth keeps the top of the mattress below most guard rails.
- Works where two beds share a room: Siblings sharing can fit two UK singles plus a walkway in rooms where anything wider would swallow the floor.
- Zoned support in a child's size: The 600 Mirapocket springs firm up where a growing back needs it, which means proper spinal support scaled to a one-person bed rather than a cut-down adult design.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and they're the most widely stocked and least expensive bedding of any UK size.
This size suits you if...
You're buying a child's first proper sprung mattress, fitting out a bunk or mid sleeper, or furnishing a compact room where the bed has to share floor space with a desk and storage. It also suits a teenager moving up from a toddler bed, or a spare room that doubles as an office and needs a bed that stays out of the way.
Consider another size if...
You need a bed for two, or you're a heavier adult after a deeper, more substantial mattress. This model is only made in a UK single, so for a shared bed you'll need a different mattress in a double or larger.

FAQ's
Will the Silentnight Healthy Growth UK single fit a bunk bed?
Yes, in most cases. At 90 x 190cm it matches the standard UK bunk and mid-sleeper frame size, and its 21.5cm depth is slim enough to sit safely below the guard rail on most raised frames. Check your frame's maximum mattress depth before ordering, as some cabin beds specify a lower limit.
What room size do I need for the Silentnight Healthy Growth UK single?
We suggest at least 2.1m x 2.8m of floor space. That gives room to walk alongside the bed and open drawers or a wardrobe. In practice a UK single fits almost any UK bedroom, including box rooms and loft conversions where the bed has to sit under a slope or against one wall.
Is the UK single Silentnight Healthy Growth long enough for a teenager?
At 190cm, or 6ft 3in, it's long enough for the vast majority of teenagers and adults, so most children won't outgrow it lengthways. The 90cm width is the standard one-person size. A particularly tall teen nearing six feet may eventually prefer the extra length of a UK king sized bed, though that would mean a different mattress.
Can adults sleep on the Silentnight Healthy Growth single in a guest room?
For occasional guests, yes. The medium feel and 600 pocket springs will support an adult perfectly well for a few nights, and the single footprint suits spare rooms that double as a study. Heavier adults may find the 21.5cm depth a little shallow for every night, since this mattress is built around a child's needs.
