Layer Details
Knitted fabric cover
A knitted fabric cover forms the top sleeping surface and is described as sumptuous. It's the part your child touches first, so it sets the feel before the layers beneath come into play.
Breathable Rebound e-Fibre comfort layer
A cushioning layer made from breathable recycled materials, with temperature and moisture-regulating properties. It adds softness over the springs and should help your child stay comfortable through the night.
e-Pocket pocket spring core
Individually pocketed springs that respond to movement and contour to the body, and are designed to target pressure points. This is what gives the mattress its medium feel and its support.
High density e-Fibre base layers
A high density e-fibre layer sits on either side of the pocket springs, which adds strength to the build. It helps the mattress cope with everyday wear from a growing child.

Key benefits
- Made for raised frames: A UK single is the standard fit for bunks, cabin beds and mid sleepers, so it should drop into most children's raised frames without fuss.
- Boxed delivery suits awkward rooms: It arrives compressed and rolled, which means you can carry it up a narrow staircase and lift it onto a top bunk far more easily.
- Leaves floor space free: At 3ft x 6ft 3in, this mattress fits a child's room that also has to hold a wardrobe, desk and toy storage, needing only 2.1m x 2.8m of floor space.
- Pocket springs sized for a child: Individual pocket springs respond to your child's weight rather than moving as one unit, useful as they grow and change position through the night.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and they're the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child's bunk, cabin bed or mid sleeper and want a sprung mattress rather than a foam slab, you need something light and boxed that one adult can get up a ladder, or you're kitting out a small child's room where a UK single is the only size that leaves space to play.
Consider another size if...
You need a mattress for an adult, a taller teen who'd suit a longer bed, or anyone wanting more than 90cm of width. This model comes in a UK single only, so a different mattress would suit you better.

FAQ's
What size is the Jay-Be Bunk e-Pocket mattress?
It comes in one size only: a UK single, measuring 90 x 190cm, or 3ft x 6ft 3in. That's the standard dimension for children's beds, bunks and mid sleepers in the UK, so standard single fitted sheets and a single duvet (135 x 200cm) will fit without any hunting for odd sizes.
Is the Jay-Be Bunk e-Pocket UK single low enough for bunk bed safety rails?
Jay-Be doesn't publish a depth figure for this mattress, and bunk safety rails have strict height rules. Before buying, check the depth on the retailer listing against your frame's maximum mattress height. The 90 x 190cm footprint itself is the standard bunk fit, so width and length shouldn't be a problem.
How small a room will a UK single mattress fit in?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which makes it a realistic fit for box rooms, loft conversions with a narrow footprint, and children's bedrooms where the bed shares space with a desk and toy storage. It's also the practical choice when siblings share and you need two beds plus a walkway.
Can two of these singles work for siblings sharing a room?
Yes, and it's a common setup: either two UK singles side by side with a gap between, or this mattress on each level of a bunk. At 90cm wide apiece, two singles plus a walkway fit rooms where a larger bed would leave no floor at all. Boxed delivery also means carrying two mattresses upstairs is manageable.
Is the UK single Jay-Be Bunk e-Pocket suitable for adults?
It's designed as a children's mattress, so we wouldn't recommend it for regular adult use. A UK single is fine for an adult in terms of footprint, but this model is built around a child's weight and needs. For a guest room or a grown-up's bed, an adult single mattress would suit you better.
