Key benefits
- Leaves floor space in a busy room: At 90cm wide, the UK single sits along one wall and leaves room for a desk and toy storage, which matters when your child's bedroom is also their playroom.
- Two beds, one shared room: A pair of UK singles can share a bedroom with a walkway between them, so brothers or sisters each get their own firm, pocket sprung bed.
- Raised frames need a depth check: The Brave is 22cm deep, so check the maximum mattress depth your bunk, cabin or mid sleeper maker allows, which keeps the guard rail high enough above your child.
- Standard bedding, easy to replace: It takes ordinary single sheets and a single duvet (135 x 200cm), which means spares for spills and bedwetting are simple to find.
- Long enough to grow into: The UK single is 190cm long and suits single adults too, so a young child is unlikely to outgrow its length before their teenage years.
This size suits you if...
Your child sleeps alone and needs a firm, supportive bed in a compact room, you're fitting out a bunk, cabin or mid sleeper frame that takes a standard UK single, or two children share a bedroom and each needs their own bed.
Consider another size if...
Your child likes a soft, cushioned surface, or you need a mattress wider than 90cm, because Silentnight makes the Brave in a UK single only.

FAQ's
Will the Silentnight Brave UK single fit a bunk bed?
It's a standard UK single at 90 x 190cm, so it matches bunk and cabin frames built for that size. The depth is the part to check. At 22cm deep, it needs a frame whose maker allows a mattress of that depth, so the guard rail still sits safely above the sleeping surface. Look at the frame's own guidance before buying.
What room size do I need for a UK single kids' mattress?
For one UK single, we suggest allowing at least 2.1m x 2.8m of floor space. That gives your child room to get in and out of bed with a wardrobe or desk nearby. If two children are sharing, plan for both beds plus a clear walkway, and measure before you choose a layout.
What bedding fits the Silentnight Brave in a UK single?
Standard single sheets fit, along with a single duvet at 135 x 200cm. As the Brave is 22cm deep, choose a fitted sheet with a pocket deep enough to tuck under the mattress comfortably. The waterproof cover helps with everyday spills, but a couple of spare sheets is still sensible for younger children.
Is a UK single big enough for a teenager?
For length, usually yes. The UK single is 190cm long, or 6ft 3in, and it's the standard one-person size for single adults as well as children. Width is the bigger question: at 3ft across, it's comfortable for one sleeper, but a teenager who sprawls may start to want more room.
Should I choose a UK small double over a UK single for my child?
A UK small double is 30cm wider and the same length, and we suggest at least 2.4m x 2.8m of floor space for one. The Brave comes in a UK single only, though, so a wider bed would mean a different mattress. If the room is tight or the frame is a bunk, the UK single is the practical fit.
