Layer Details
Cover
A knitted fabric cover, which means a soft touch surface against your sheets.
Advanced e-Fibre®
Jay-Be's award-winning Advanced e-Fibre® sits just below the cover for luxury comfort. It's also breathable, so heat can escape rather than build up around you.
Memory e-Fibre®
A fibre alternative to memory foam, giving quick response pressure relief. You get cushioning at the shoulders and hips without the slow sink of traditional foam.
Rebound e-Fibre®
Rebound e-Fibre® provides contour support, which means it follows your shape while pushing back enough to keep you from bottoming out.
Micro e-Pocket™ springs
A layer of small pocket springs that move independently for adaptable support. They respond to each part of your body separately, useful if you and a partner are different weights.
e-Spring™ core
The e-Spring™ core forms the base of the mattress, providing the main structural support beneath the comfort layers.

Key benefits
- Shallow enough for bunks and mid sleepers: At 21cm deep, the S7 sits below the safety rail line on most bunk, cabin and mid sleeper frames, which many deeper hybrids do not.
- A soft feel suited to lighter bodies: Singles are mostly bought for children, teens and lighter adults, exactly the sleepers a soft mattress supports properly.
- Leaves floor space in a child's room: At 3ft wide it leaves room for a desk, wardrobe and toy storage in a bedroom that has to do several jobs at once.
- Two can fit where one double won't: Siblings sharing, or a guest room set up with twin beds, can take two UK singles with a walkway between them.
- A sensible buy for a child who'll recycle it: Children outgrow mattresses; this one is 100% recyclable, so replacing it in a few years doesn't mean sending foam to landfill.
- Fits almost any room: We suggest allowing at least 2.1m x 2.8m of floor space, which most UK bedrooms, box rooms and loft conversions can manage.
This size suits you if...
You're buying for a child or teenager, especially on a bunk or mid sleeper where the 21cm depth keeps the safety rail effective, you're a lighter adult who sleeps alone and likes a soft feel, or you're kitting out a spare room or student flat where the frame is a single and floor space is tight.
Consider another size if...
You're an adult who wants proper room to stretch out, or you sometimes share the bed. We'd recommend the UK double instead: it's 45cm wider than the UK single, and we suggest allowing at least 2.6m x 2.8m of floor space for it.

FAQ's
Is the Jay-Be Benchmark S7 UK single suitable for a bunk bed?
Yes, in most cases. The S7 is 21cm deep, and the UK single's 90 x 190cm footprint matches standard UK bunk, cabin and mid sleeper frames. Do check your frame's maximum mattress depth against the safety rail height before buying, as this varies between frames, but 21cm sits within the limit on most.
Is the Jay-Be S7 UK single a good mattress for a child or teenager?
It's a strong match. The soft feel suits lighter bodies, the fibre layers breathe well for warm sleepers, and the foam-free build means no chemical emissions in a child's room. When it's eventually outgrown, the whole mattress is recyclable. Heavier teens who prefer a firm surface may find it a little too soft.
How much bigger is the UK small double than the UK single?
The UK single is 30cm narrower than the UK small double, and the two are the same length. If your child is heading into their teens and the room allows, that extra width buys years more use. For the UK small double we suggest allowing at least 2.4m x 2.8m of floor space.
Will the S7 in a UK single fit a spare room that doubles as an office?
Usually, yes. At 90 x 190cm it's the smallest standard adult size, and we suggest allowing at least 2.1m x 2.8m of floor space, which leaves room for a desk in most spare rooms. The soft feel suits occasional guests, though heavier visitors may find it lacks firmness for regular use.
Is a UK single long enough for a tall sleeper?
The UK single is 190cm long, or 6ft 3in, so most sleepers fit comfortably, but very tall teens or adults may feel cramped. The UK king is 10cm longer, though it's a two-person size at 60cm wider than the UK single. In this range there's no longer single option, so check height carefully first.
