Layer Details
- Cover. A knitted fabric cover, which means a soft-touch surface against your skin from the moment you lie down.
- Advanced e-Fibre®. An award-winning comfort layer designed for luxury comfort and breathability, so air moves through rather than building up heat.
- Memory e-Fibre®. A memory layer offering quick-response pressure relief. Unlike traditional memory foam, it recovers quickly, so you won't feel stuck when you change position.
- Rebound e-Fibre®. A rebound layer that contours to your shape, which means support that follows your body rather than a flat, rigid feel.
- e-Spring™ core. A deep sprung core with supportive comfort layers, giving the mattress its firm, stable foundation.
Layer details from furniturevillage.co.uk product page, September 2026.
- A depth that suits raised frames: At 19cm deep, it stays below the guard rails on most bunk, cabin and mid-sleeper frames, where a taller mattress can be unsafe.
- Firm support for growing sleepers: The firm e-Spring™ core gives children and teens a stable, supportive surface rather than a soft one they sink into.
- Fits a small footprint: At 90cm wide, it leaves room for a desk, wardrobe and toy storage in a compact child's bedroom; allow at least 2.1m x 2.8m of floor space.
- Sleeps cooler than foam: The e-Fibre® layers let air move through rather than trapping heat, which matters in a top bunk where warm air collects.
- Guest rooms and spare-room offices: A UK single tucks against a wall in a room that doubles as a study, keeping the floor clear during the working day.
- Recyclable at the end of its life: The foam-free construction is 100% recyclable, a genuine plus when replacing outgrown children's mattresses every few years.
This size suits you if...
You're buying for a child or teenager moving up from a cot or outgrowing an old mattress, you need something slim enough for a bunk or mid-sleeper frame, or you're kitting out a guest bed or first flat where the frame is a UK single and the room is tight. The firm feel suits back and front sleepers who want support rather than sink.
Consider another size if...
You're an adult who shares the bed, or you simply want more stretching room than 90cm allows. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Will the Jay-Be Benchmark S3 UK single fit a bunk bed?
It's well suited to one. At 19cm deep, it should sit below the guard rails on most bunk, cabin and mid-sleeper frames, where a deeper mattress can leave too little rail exposed. The 90 x 190cm footprint matches standard UK single frames, though it's sensible to check your frame's stated maximum mattress depth before buying.
Is the Jay-Be Benchmark S3 UK single a good choice for a child?
Yes, with one caveat. The firm feel gives children and teens stable support as they grow, and the breathable e-Fibre® layers keep the surface cooler than foam. The caveat is lightweight side sleepers, who may find it slightly hard on shoulders and hips. For most children moving to their first big bed, it's a sensible fit.
How much bigger is a UK small double than this single?
The UK small double is 30cm wider than the UK single, and the two are the same length. That extra width gives a solo teen or adult noticeably more room to spread out. You'd need a slightly larger room: we suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single.
What room size do I need for the Jay-Be Benchmark S3 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough clearance to walk round the bed and open drawers or a wardrobe. In a child's room competing with a desk and toy storage, or a loft conversion where the bed sits under the slope, the 90cm width is what makes the layout work.
