Sleep surface
A soft knitted fabric, which gives a gentle, comfortable feel against skin. The fabric is OEKO-TEX® 100 certified and uses anti-allergy, anti-dust mite probiotic technology.
Comfort layer
A breathable Rebound e-Fibre™ comfort layer, made with more than 70% recycled content. Being fibre rather than foam, it allows air to move through, which helps children who tend to sleep warm.
Core
An e-Spring™ core that provides evenly distributed support across the mattress. Jay-Be describes it as medium firmness, a good all-round feel for growing bodies.

Key benefits
- Made for raised frames: At 90 x 190cm with a 16cm profile, it sits within the depth limits of most bunk and mid-sleeper frames, so the safety rail stays usefully high.
- Fits a crowded child's room: A UK single is 3ft wide, which leaves floor space for a desk, wardrobe and toy storage in a typical child's bedroom.
- Works doubled up: Where siblings share, two UK singles plus a walkway fit rooms that a bigger bed would swallow, and both children get the same medium support.
- Cool for top-bunk sleepers: The fibre comfort layer lets air move through, which matters on a top bunk where warm air collects near the ceiling.
- Easy, cheap bedding: Standard single sheets and a single duvet (135 x 200cm) fit, and they're the most widely stocked bedding of any UK size.
This size suits you if...
You're kitting out a bunk, cabin or mid-sleeper frame and need a mattress shallow enough for the rail to stay effective, you're furnishing a child's or teenager's room where floor space is tight, or you want two matching beds for siblings sharing without giving up the walkway between them.
Consider another size if...
You need anything wider than 90cm, or the sleeper is an adult or heavier teenager. This mattress only comes in a UK single, so a small double or double frame will need a different mattress entirely.

FAQ's
Will the Jay-Be Bunk e-Sprung UK single fit my bunk frame?
It should fit any frame built for a standard UK single, as it measures 90 x 190cm (3ft x 6ft 3in). The part to check is depth: most bunk and mid-sleeper frames specify a maximum mattress height so the guard rail stays effective, and at 16cm this mattress sits comfortably under most limits.
What room size do I need for the Jay-Be Bunk e-Sprung in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That's our own guidance rather than Jay-Be's, and it leaves enough room to walk round the bed and open drawers. In practice a single is the easiest size to place, even under a loft conversion slope.
Does the Jay-Be Bunk e-Sprung come in any size other than a UK single?
No, the UK single is the only size Jay-Be makes this mattress in. That reflects what it's for: bunk beds, cabin beds and mid sleepers are almost always single-width frames. If you need a small double or double, you'll be looking at a different mattress rather than a different size of this one.
Is a UK single big enough for a teenager?
For most teenagers, yes: at 90cm wide and 190cm long, a UK single suits growing sleepers well into their teens. The caveat with this particular mattress is its 16cm depth, which heavier teenagers may find a little slim compared with a full-depth adult mattress, although it's ideal while they're on a raised frame.
Can I use two UK singles for siblings sharing a room?
Yes, and it's a sensible setup. Two 90cm-wide beds leave more usable walkway between them than one larger bed pushed to a wall, and each child gets the same medium-feel support. If one bed is a bunk or mid sleeper, the slim 16cm depth keeps the rail height right on the top frame.
