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
- Room to stretch out alone: The UK small double is 30cm wider than the UK single, which means you can turn over or sprawl without an arm or knee drifting off the edge.
- Suits compact bedrooms: We suggest a room of at least 2.4m x 2.8m, so it can work in a box room where a UK double would leave the door or wardrobe struggling to open.
- Fine for occasional couples: Two adults can share it for a visit, although if you share every night, the UK double's 67.5cm each will feel noticeably less cramped.
- Deep sheets needed: At 31cm deep, the Jura needs deep-pocket small double fitted sheets, which means checking the pocket depth on the packet before you buy bedding.
- Natural build in a smaller footprint: Latex and organic British lambswool over pocket springs come at this width too, so a small room needn't mean settling for a simpler mattress.
This size suits you if...
You sleep alone and like room to roll over freely, your bedroom can't spare the floor a UK double would take, or you're furnishing a guest room where couples stay now and then rather than every night.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each and needs a room of at least 2.6m x 2.8m.

FAQ's
Is the Hypnos Jura UK small double big enough for two people?
For a weekend guest stay, yes, most couples manage comfortably enough. For nightly sharing it's a squeeze, and we'd point you to the UK double, which gives 67.5cm each. Bear in mind that a UK double needs a room of at least 2.6m x 2.8m, compared with 2.4m x 2.8m for the UK small double.
What size room do I need for a Hypnos Jura small double?
We suggest at least 2.4m x 2.8m. In a box room or loft conversion, check the door can still swing open with the bed in place, and measure any tight stair turns too. Once you're sure it fits, compare the retailers listed on this page for the Jura in this size.
Hypnos Jura small double vs double: which should I buy?
The UK small double is 15cm narrower than the UK double, and they're the same length. If you sleep alone, those 15cm rarely matter and the smaller room needs are useful. If a partner joins you most nights, the UK double is the better buy.
Is a UK small double Hypnos Jura a good upgrade from a single for a teenager?
It's a sensible step up. The UK small double is 30cm wider than the UK single but the same length, so a tall teenager gains width, not legroom. The room needs grow modestly too: we suggest 2.1m x 2.8m for the UK single and 2.4m x 2.8m for the UK small double.
What bedding fits the Hypnos Jura in a UK small double?
Buy small double fitted sheets with pockets deep enough for a 31cm mattress, as shallow ones tend to ping off the corners. A standard double duvet hangs nicely over the 120cm width, giving a little overhang on each side.
