Layer Details
- Fabric cover. A deep quilted cover made from OEKO-TEX Standard 100 certified fabric, enriched with Margosa and linseed oils. The certification means the fabric has been tested against harmful substances, a reassurance for allergy-prone sleepers.
- Comfort layer. Extra-soft Advance e-Fibre sits directly beneath the cover, giving gentle cushioning at the surface. It also supports airflow and moisture control, which helps you stay drier through the night.
- Comfort layers. Breathable, open-structured comfort layers let air circulate freely through the mattress. The whole design is 100% foam-free, so heat has somewhere to go rather than sitting around you.
- Spring core. 800 individually pocketed springs each respond to your body independently, adapting to your shape rather than moving as one unit. That independence also reduces motion transfer, so a restless partner is less disruptive.
Layer details from jaybe.com product page, September 2026.
- A sensible first proper mattress: The medium feel and independent pocket springs support a growing child or teenager without the sink of memory foam, which suits lighter bodies well.
- Allergy care where it matters most: Children's rooms are where allergies often show up first, and the Margosa and linseed oil enriched cover is designed to keep allergens at bay.
- Slim enough for raised frames: At 23cm deep it sits comfortably within the guard rails of most bunk beds, cabin beds and mid sleepers, where chunkier hybrids often ride too high.
- Room left over for everything else: At 3ft wide it leaves space for a desk, wardrobe or toy storage in a compact room, or two beds with a walkway between for sharing siblings.
- Cool for warm rooms: The foam-free, open-structured layers let heat escape, which helps in small bedrooms and loft rooms that warm up quickly in summer.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and least expensive of any size, handy when kids' bedding needs replacing often.
This size suits you if...
You're buying for a child or teenager, especially one with allergies, and want a certified, foam-free build under them. It also fits if you're kitting out a bunk, cabin or mid-sleeper frame where a slim 23cm depth matters, or furnishing a spare room or study that occasionally hosts guests and needs the floor space back the rest of the time.
Consider another size if...
You're an adult couple, or a solo sleeper who likes to spread out. The Jay Be Pure Anti-Allergy 800 Pocket in a UK double is 45cm wider and the same length; we suggest at least 2.6m x 2.8m of floor space for it.

Will the UK single Jay Be Pure Anti-Allergy 800 Pocket fit a bunk bed?
In most cases, yes. Standard UK bunk, cabin and mid-sleeper frames take a 90 x 190cm mattress, which is exactly this size. Depth is the usual concern with raised frames, and at 23cm this mattress sits lower than many hybrids, so the guard rail should still do its job. Do check your frame's stated maximum depth before ordering.
Is the UK single Jay Be Pure Anti-Allergy 800 Pocket good for a child?
It's a strong fit. The medium firmness gives a growing body support without feeling hard, the pocket springs adapt to lighter weights, and the anti-allergy cover with OEKO-TEX Standard 100 certified fabric is reassuring for allergy-prone children. The foam-free construction also runs cooler, which helps kids who kick the duvet off.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk round the bed and open drawers. The mattress itself is 90 x 190cm, so it works in box rooms, under loft slopes where only a narrow footprint fits, and in shared children's rooms with two beds and a walkway between.
Is a single big enough for an adult guest room?
For occasional guests, yes. One adult sleeps comfortably on 90cm of width, and a single leaves space for a desk if the room doubles as an office. If guests often come as couples, the Jay Be Pure Anti-Allergy 800 Pocket in a UK small double is 30cm wider and the same length; allow at least 2.4m x 2.8m for it.
