Layer Details
- Comfort Layer. Soft White Fibre fillings sit at the top of the mattress, which means a cosy, gently cushioned surface for your child to settle onto. It's a simple comfort layer rather than a deep plush one, in keeping with the mattress's slim bunk-friendly depth.
- Support System. The e-Pocket core uses individual springs encased in cloth pockets, which means each spring adapts to movement independently and support follows your child's body. That's a step up from the open-coil or all-foam cores common in budget children's mattresses.
- Base. A high density e-Fibre base underpins the springs and delivers full body support. It's made from approximately 65% recycled plastic bottles, so the foundation of the mattress is doing some environmental good too.

- Made for raised frames: The UK single is the size most bunk, cabin and mid sleeper frames are built around, so this mattress drops into the frame it was designed for.
- Safety rails stay effective: Its slim 16cm depth means the top bunk rail still stands well above the sleeping surface, which is exactly what you want for a child sleeping up high.
- Room left over for everything else: At 3ft wide, a UK single leaves floor space for a wardrobe, a desk and the inevitable toy storage in a compact child's bedroom.
- Works for shared rooms: Two UK singles, whether bunked or side by side with a walkway between, are the standard answer when siblings share, and this mattress suits either setup.
- Easy, cheap bedding: Single sheets and duvets are the most widely stocked bedding in the UK, so replacing a child's outgrown or worn set costs very little.
This size suits you if...
You're buying for a bunk bed, cabin bed or mid sleeper and need a mattress shallow enough to keep the safety rail effective, your child's room is compact and every centimetre of floor space matters, or you have siblings sharing and want two matching beds that still leave a walkway between them.
Consider another size if...
Your child sleeps in a standard bed frame rather than a raised one, where the slim 16cm profile will look and feel low, or the sleeper is an adult or heavier teenager who needs more substantial support than a children's mattress provides.

Will the Jay-Be e-Pocket UK single fit my bunk bed frame?
Almost certainly, as UK bunk, cabin and mid sleeper frames are built around the UK single's 90 x 190cm footprint. Measure the inside of your frame before ordering to be sure, particularly with older or imported frames. The 16cm depth also keeps the mattress surface safely below the top bunk's guard rail.
Is a UK single big enough for a teenager on this mattress?
For size, yes: at 90 x 190cm the UK single is the standard one-person size and suits most teens. The caveat is the mattress itself, which is designed for children. Jay-Be's medium firm support may feel a little slim for a heavier teenager, so it's better suited to younger sleepers.
Can two Jay-Be e-Pocket UK singles fit in a shared kids' room?
Often, yes. We suggest at least 2.1m x 2.8m of floor space for one UK single, so two beds side by side need a wider room with space for a walkway between them. If the room is tight, bunking them is the space-saving answer, and this mattress is built for exactly that.
How much floor space does a UK single bunk bed need?
We suggest allowing at least 2.1m x 2.8m for a UK single. A bunk uses the same footprint as one bed while sleeping two, which is why it suits compact rooms and loft conversions where only a narrow strip of full-height floor is usable. Check ceiling height above the top bunk too.
