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.

- Real room for one: The UK small double is 30cm wider than the UK single, which means space to spread out or shift position without your elbow finding the edge.
- Fits where a double won't: At 15cm narrower than a UK double, it can be the difference between a bedroom door that clears and one that doesn't.
- Allergy-conscious for guest rooms: The OEKO-TEX certified cover with Margosa and linseed oils suits a spare room where you can't predict which visiting sleeper has sensitivities.
- Less disturbance when shared: With 800 pocketed springs responding independently, occasional couple use is more comfortable than the 4ft width might suggest, as one person turning barely reaches the other.
- Cooler in small rooms: The foam-free layers let air move through, useful in compact bedrooms and loft rooms that hold heat in summer.
This size suits you if...
You sleep alone and want noticeably more width than a UK single without giving your room over to the bed; you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly; or you're setting up a teenager's room where a single feels outgrown but floor space is tight. The medium feel and cooler, foam-free build suit most of these sleepers well.
Consider another size if...
You're a couple sharing every night, since 120cm across leaves little personal space long term. We'd recommend the UK double instead, which is 15cm wider and the same length; allow a room of at least 2.6m x 2.8m.

Is the Jay Be Pure Anti-Allergy 800 Pocket small double big enough for a couple?
For occasional nights, yes. The 800 pocketed springs move independently, so at 120cm wide two people sharing a guest bed won't disturb each other much. For nightly sharing it's a squeeze, and the UK double, 15cm wider at the same length, is the more comfortable long-term choice.
What room size do I need for a small double mattress?
We suggest at least 2.4m x 2.8m for a UK small double. That allows walking space along one side and room for a wardrobe or chest of drawers, which is usually the deciding factor in the box rooms and loft conversions this size tends to end up in.
How much bigger is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is what makes it appealing for a teenager or solo adult who feels hemmed in on a single but whose room can't take a full double.
Will the Jay Be Pure Anti-Allergy 800 Pocket small double fit in a box room?
Often, yes. At 120 x 190cm it's 15cm narrower than a UK double, which in a small room can decide whether the door still opens fully or you can stand beside the bed. Measure your usable floor space against our suggested minimum of 2.4m x 2.8m before ordering.
