Layer Details
Natural latex
Two naturally supporting latex layers, used instead of memory foam. That means support from a natural material rather than a foam one.
Organic British lambswool
At least five full fleeces of organic British lambswool, whichever tension you choose. That gives you a natural, cushioned comfort layer.
ReActivePro 7-turn pocket springs
Hypnos' ReActivePro 7-turn pocket springs form the support base. Hypnos doesn't publish a spring count for this mattress.

Key benefits
- Fits a small bedroom: At 90 x 190cm, the UK single leaves floor space for a desk or wardrobe, and we suggest allowing at least 2.1m x 2.8m.
- Natural materials for one: Latex and organic British lambswool sit over ReActivePro 7-turn pocket springs, which means a cushioned, natural-feeling surface rather than the slow sink of memory foam.
- Low upkeep in a guest room: The no-turn construction means nobody has to flip a spare-room single between visitors, which helps when that room spends most weeks as a study.
- Ordinary bedding fits: Standard single sheets and a single duvet (135 x 200cm) fit, so a guest bed or child's bed needs no special linen.
- Depth suits a standard frame: Yes, 31cm is a lot for a bunk or mid sleeper, but on a standard single frame that depth gives a deep, well-cushioned sleeping surface.
This size suits you if...
You sleep alone and want natural materials in a compact bedroom, or you're furnishing a child's or teenager's room where a desk and wardrobe still need their share of the floor. It also suits a spare room that works as an office most of the week, or a loft conversion where only a narrow bed fits beneath the sloping ceiling.
Consider another size if...
You share the bed most nights with a partner. We'd recommend the UK double instead: it gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m of floor space for it.

FAQ's
Will the Hypnos Jura UK single fit a bunk bed or mid sleeper?
Check carefully first. The Jura is 31cm deep, and raised frames often set a maximum mattress depth so the guard rail stays effective. Measure against the frame maker's guidance, then compare the retailers listed on this page. On a standard single bedstead or divan, the depth is no problem.
Is a UK single Hypnos Jura a good choice for a child's room?
It can be, provided the room has a standard frame. The 90 x 190cm footprint leaves space for toy storage and a desk, and we suggest at least 2.1m x 2.8m of floor. Hypnos doesn't publish a firmness for the Jura, so check the tension suits a lighter sleeper before buying.
How much room do I need for a UK single Hypnos Jura?
We suggest at least 2.1m x 2.8m for a UK single. That suits a box room or a spare room used as a study. If two siblings share a room with a single each, plan the layout so there is a clear walkway between the beds.
Hypnos Jura single or small double for one adult?
The UK single is 30cm narrower than the UK small double and the same length. In a small room, the UK single saves floor space. If you tend to spread out, the UK small double would suit you better, and we suggest at least 2.4m x 2.8m for it.
Is the Jura UK single long enough for a tall teenager?
The UK single is 190cm long, or 6ft 3in, the same length as the UK small double and UK double. The UK king is 10cm longer than the UK single, so if your teenager is close to 190cm already, that's the size that adds length, though we suggest at least 2.7m x 2.9m for it.
