Layer Details
- Knitted cover. A soft knitted finish that adds cosiness and warmth, which means the surface feels gentle rather than scratchy against skin. It also enhances airflow and breathability.
- e-Fibre comfort layers. Breathable fibre layers that regulate temperature and moisture, so a warm sleeper is less likely to overheat. This is where the mattress gets its cushioning without using foam.
- Deep e-Pocket springs. Individual springs sit in their own cloth pockets, which means each one responds separately to movement. That gives support tailored to how and where your child lies.
- 3D spacer base layer. A resilient yet cushioning core that spreads weight evenly across the mattress surface. It underpins the springs and helps the whole mattress support consistently edge to edge.

- Fits the smallest bedrooms: At 90cm wide it leaves floor space for a desk, wardrobe and toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Suits raised frames: The lighter, shallower build of a children's mattress sits comfortably in bunk beds, cabin beds and mid sleepers, where safety rails need to clear the mattress top.
- Works in pairs: Two UK singles fit a shared siblings' room or a twin guest room where a double simply wouldn't, with a walkway left between them.
- Pocket springs at a children's size: Cloth-encased springs respond individually to a light body, so a child gets adaptive support rather than lying on a flat block of filling.
- Cool under a duvet: The e-Fibre layers and knitted cover are designed for airflow, useful for children who run warm and kick the covers off.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any UK size, so replacing outgrown or ruined bedding is quick and inexpensive.
This size suits you if...
You're kitting out a child's or teenager's room where the bed has to share floor space with a desk and storage, you need a mattress for a bunk, cabin or mid sleeper frame, or two siblings share a room and a pair of UK singles is the only layout that leaves a walkway.
Consider another size if...
You need a bed for two, or a spare room that regularly hosts adult guests. The QUEST Q2 is made in the UK single only, with no larger sizes available, so a couple's room needs a different mattress entirely.

What are the dimensions of the Jay-Be QUEST Q2 in a UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK single, so it fits any standard single bed frame, bunk or mid sleeper without gaps at the edges, and standard single fitted sheets and a 135 x 200cm single duvet fit it exactly.
Will the Jay-Be QUEST Q2 fit a bunk bed or mid sleeper?
Yes, and it's a sensible pairing. Raised frames usually specify a maximum mattress depth so the safety rail still does its job, and at 18cm the QUEST Q2 sits within most limits. Check your frame's stated maximum before buying, but this is exactly the kind of mattress those frames are designed around.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk round the bed and open drawers or a wardrobe. In practice a UK single is the easiest size to place: it works under a loft slope or against a wall where nothing wider would.
Does the Jay-Be QUEST Q2 come in any size other than a UK single?
No, the UK single is the only size Jay-Be makes this mattress in. That fits its purpose as a children's mattress, since the UK single is the standard size for kids' beds, bunks and mid sleepers. If you need a UK small double or bigger, you'll need to look at a different model.
Is the Jay-Be QUEST Q2 UK single big enough for a teenager?
Yes. The UK single is the standard size for teenagers as well as younger children, and at 190cm long it accommodates most teens comfortably through to adulthood. Taller teens still fit, although anyone well over six foot may eventually prefer the extra 10cm of length a UK king offers in a future bed.
