Layer Details
Woven top surface
The top is a soft woven fabric treated with Purotex, the anti-allergy treatment. It gives your child a soft surface to lie on, and suits families who want an allergy-conscious cover.
Rebound e-Fibre comfort layer
E-Fibre fillings sit under the cover and add comfort, moisture control and temperature control. This is a foam-free layer, so the cushioning comes from fibre rather than foam.
High-density eco e-Fibre insulator
This eco e-Fibre insulator works alongside the comfort fillings so your child doesn't feel the springs through the mattress. It keeps the medium-firm sprung feel from being uncomfortable on top.
Spring unit
The springs give a supportive sleeping surface, and a cushioned border surrounds them. Together they give the medium-firm support a growing child needs, though no spring count is published.

Key benefits
- Made for the frames children actually have: At 90cm wide, the UK single matches standard bunk beds, cabin beds and mid sleepers, which is where most children's mattresses end up.
- Leaves the rest of the room free: A child's bedroom has to hold toy storage, a wardrobe and often a desk, and the UK single's 3ft width keeps floor space for all of it.
- Works for two beds in one room: Siblings sharing a room can usually fit two UK singles with a walkway between, something no wider size allows in a typical UK bedroom.
- Anti-allergy, foam-free build in the everyday size: The sprung, foam-free construction, which some parents prefer for younger sleepers, comes here in the size a child will use for years.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and least expensive of any size, which matters when children's bedding needs replacing often.
This size suits you if...
You're buying for a child's room where the bed shares space with storage and a desk, you need a mattress for a bunk, cabin or mid-sleeper frame, or you have two children sharing and need two beds plus room to walk between them. It also suits a spare room that doubles as an office, where a slim footprint is the priority.
Consider another size if...
Your child is a restless sleeper or nearly grown and needs more width than 90cm. The UK small double is 30cm wider at the same length, and we suggest allowing at least 2.4m x 2.8m of floor space for it.

FAQ's
What size is the Jay Be Simply Kids mattress in a UK single?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in. That's the standard one-person size in the UK, so it fits ordinary single bed frames, divans and most children's novelty frames without any guesswork.
Will the UK single Jay Be Simply Kids mattress fit a bunk bed or mid sleeper?
The width will: bunks and mid sleepers in the UK are built around the 90 x 190cm single. The one thing to check is depth, since raised frames often set a maximum mattress height for safety rails, and JAY-BE doesn't publish a depth for this mattress. Confirm with the retailer before buying for a raised frame.
How much floor space does a UK single need in a child's room?
We suggest allowing at least 2.1m x 2.8m. That leaves enough clearance to make the bed and open drawers, with room left over for a wardrobe or desk. In a loft room, the UK single's narrow footprint also makes it the easiest size to tuck under a sloping ceiling.
Is the UK single Jay Be Simply Kids mattress big enough for a teenager?
For most teenagers, yes. At 190cm long it's the same length as a UK double, so height is rarely the issue. Bear in mind this is a mattress designed for children, so it's a school-years purchase rather than one to carry into adulthood.
Where can I buy the Jay Be Simply Kids mattress in a UK single?
Retailer stock changes, so the most reliable answer is the live price table on this page, which updates as retailers change their listings. Compare what's shown there rather than relying on an older page, and check each retailer's own terms, since extras like trials vary by seller rather than coming from JAY-BE.
