Layer Details
Micro e-Pocket® springs
A layer of smaller pocket springs sits at the surface, responding to even gentle movements. In practice this means a closer, more contouring feel than a single spring unit would give.
Deep e-Pocket™ Core
Beneath the micro springs is a deep pocket spring core providing responsive support. This is the layer doing the structural work, keeping your spine supported while the top layer handles comfort.

Key benefits
- Fits compact rooms: At 90cm wide it leaves floor space free, useful where a bed shares the room with a desk, wardrobe and toy storage.
- Springy feel suits growing sleepers: Micro e-Pocket springs over a deep e-Pocket core respond quickly to movement, which many children and teens prefer to a foam sink.
- Good for shared kids' rooms: Two UK singles plus a walkway fit in most sibling bedrooms, and pocket springs move independently so each bed feels supportive on its own.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and lowest-cost bedding of any UK size.
- Guest-room ready: In a spare room that doubles as an office, a UK single keeps the desk usable while still offering guests a proper pocket spring mattress.
This size suits you if...
You're buying for one sleeper: a child moving up from a cot bed, a teenager, a student flat where the frame is provided, or a guest room. It also suits rooms where space is tight, since we suggest allowing just 2.1m x 2.8m of floor space, and it works well where two beds need to share a children's room.
Consider another size if...
You share the bed or want more stretching room, since the Quest Q3 Epic Comfort is only made in a UK single. There's no bigger size to point you to, so couples will need a different mattress entirely.

FAQ's
Does the Jay Be Quest Q3 come in a double or king?
No. The Quest Q3 Epic Comfort is listed in the UK single only, at 90 x 190cm. If you need a UK double or UK king, you'll have to choose a different mattress, as there's no larger version of this one to size up to.
What room size do I need for the Jay Be Quest Q3 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That's our own guidance rather than the manufacturer's, and it leaves room to walk around the bed and open drawers. In practice a UK single fits almost any UK bedroom, including box rooms and lofts with a narrow footprint.
Is the UK single Quest Q3 a good choice for a child's bed?
Yes, with a caveat. The UK single is the standard children's size, and the springy, responsive feel of the micro spring layer tends to suit lighter, growing sleepers better than a deep foam sink. JAY-BE doesn't publish a firmness rating though, so very light children may find it hard to judge before trying.
Will the Quest Q3 single fit 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, and JAY-BE doesn't publish a depth here, so check your frame's limit against the retailer listing before buying.
What bedding fits the Jay Be Quest Q3 UK single?
Standard UK single fitted sheets, sized for a 90 x 190cm mattress, and a single duvet at 135 x 200cm. Single bedding is the cheapest and most widely available of any UK size, handy if you're kitting out a child's room or a guest bed on a budget.
