Layer Details
- Soft knitted fabric surface. A soft knitted fabric top that's kind to the skin. It's the layer you'll actually feel through your sheet, so the gentle finish matters more than it sounds.
- Breathable comfort layers. These sit just beneath the surface and help regulate moisture. In practice, that means less clamminess on warm nights.
- Advanced 3D Spacer. A spacer layer designed for extreme breathability, letting air circulate through the mattress. This is the heart of its temperature control.
- Deep e-Pocket Core. A deep pocket spring core giving responsive contour support. Each spring moves independently, so the mattress follows the shape of your body rather than pushing back evenly.

- A footprint that leaves the room usable: At 90cm wide, it leaves space for a desk, wardrobe and toy storage in a child's bedroom rather than swallowing the floor.
- Foam-free breathability for kids and teens: Children run warm at night, and the Advanced 3D Spacer layer lets air move through the mattress rather than trapping heat around them.
- Medium firm support through growing years: The deep e-Pocket core adjusts to each sleeper individually, which means it supports a growing teenager as well as it does an adult.
- Hypoallergenic where it matters most: Singles are often bought for children, so the hypoallergenic, completely foam-free materials are reassuring if allergies run in the family.
- Sensible for spare rooms and first flats: A UK single suits a spare room that doubles as an office, or a student room where the frame is provided and the mattress isn't.
This size suits you if...
You're buying for a child or teenager and want a breathable, foam-free mattress in the standard kids' bed size; you sleep alone and your bedroom is on the compact side; or you're furnishing a guest room, study or student let where a 90 x 190cm footprint keeps the rest of the room usable.
Consider another size if...
You share the bed, or you're a solo sleeper who likes to spread out. The Quest Q2 is currently made in a UK single only, so you'd need a different mattress rather than a different size of this one.

What are the dimensions of the Jay Be Quest Q2 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard one-person size in the UK, so it fits any standard single frame, and ordinary single sheets and duvets will fit without adjustment.
Does the Jay Be Quest Q2 come in a double or king?
Not at the moment. The Quest Q2 is currently listed in a UK single only, so if you need a wider mattress you'd be choosing a different model rather than sizing up. For one sleeper, though, the 90cm width is the UK standard.
Is the Jay Be Quest Q2 UK single a good choice for a child's bedroom?
It's a sensible fit. The UK single is the default size for children's beds, the materials are hypoallergenic, and the foam-free construction with its Advanced 3D Spacer layer keeps air moving, useful for children who run hot at night. The medium firm feel gives proper support as they grow, although some children prefer a softer surface.
How much room do I need for the Jay Be Quest Q2 UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a shared children's room with two singles and a walkway between them, you'll want comfortably more than that minimum.
Can I use the Jay Be Quest Q2 UK single on a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, so width and length are fine. Raised frames often have a maximum mattress depth for the guard rail to work safely, so check your frame's limit against the mattress before buying. The breathable, foam-free build suits children's raised beds well.
