Layer Details
Bio Fresh fabric
The sleeping surface is Bio Fresh fabric, enriched with sustainable, natural herbal extracts. It's the layer your child lies closest to, and it's OEKO-TEX 100 certified along with the rest of the mattress.
Breathable e-Fibre™ comfort layers
Breathable e-Fibre comfort layers provide the cushioning in place of foam, which means air can move through the mattress more freely. That helps keep the sleeping surface cooler through the night.
Deep e-Pocket™ core
A Deep e-Pocket core provides responsive support, with each pocketed spring moving independently. In practice that means the mattress adapts to your child's body rather than pushing back as one solid unit.
Cushioned border
A cushioned border runs around the edge for increased durability. It helps the mattress keep its shape over years of use, useful given how children treat their beds.

Key benefits
- Room to spread out alone: It's 30cm wider than the UK single, which means a solo sleeper can turn over or sleep starfished without an arm hanging off the edge.
- Same length as a single: The UK small double matches the UK single for length, so upgrading a growing teenager adds width without pushing the bed further into the room.
- Kinder to tight floor plans: It's 15cm narrower than the UK double, a small margin that can decide whether a door swings clear or a bedside table still fits.
- Cooler for one, cooler for two: The foam-free e-Fibre layers let air move through the mattress, which helps on the nights an occasional guest shares the bed and adds body heat.
- Easy to dress: A 4ft bed is a standard UK size, so you can buy small double fitted sheets and use an ordinary double duvet on top.
This size suits you if...
You sleep alone and want more width than a single without giving up much floor, or you're furnishing a box room, loft conversion or second bedroom where couples only stay now and then. It also fits a teenager who has outgrown a single in a room that can't spare the space.
Consider another size if...
Two of you will share it every night. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Will a UK small double mattress fit in a box room?
Often, yes. We suggest allowing at least 2.4m x 2.8m for a UK small double, which leaves room to walk round the bed and open the door. Measure with the door swing and any radiators in mind, because a few centimetres can make the difference in a narrow room.
Is the Jay Be Bio Fresh small double a good upgrade for a teenager?
It can be. The UK small double is 30cm wider than the UK single but the same length, so a teenager gains turning room without the bed reaching further across the floor. JAY-BE positions this mattress for children, so check the brand's own guidance if your teenager is near adult height or weight.
Can two people sleep on a UK small double Jay Be Bio Fresh?
For the odd night, yes, which is why it suits guest rooms. For nightly sharing it gets tight, and the UK double would be more comfortable, giving 67.5cm each. The independent pocket springs help limit how much one person's movement reaches the other, but they can't add width.
What bedding fits a 4ft small double mattress?
Look for fitted sheets labelled small double or 4ft, as a standard double sheet will be loose at 120cm wide. On top, a standard double duvet works well and gives a little overhang on each side. Both are widely sold in the UK.
How much bigger is a UK double than a small double?
The UK double is 15cm wider than the UK small double, and the two are the same length. It needs more floor too: we suggest at least 2.6m x 2.8m for the UK double, compared with 2.4m x 2.8m for the UK small double.
