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
- Shared space without losing the room: Two sleepers get 67.5cm each, which means room to turn over at night while still leaving floor space for a wardrobe and drawers.
- Fits where a UK king would not: We suggest allowing at least 2.6m x 2.8m, so the UK double suits many master bedrooms in terraces and new builds that cannot take a UK king.
- Space for bedside tables: Being 15cm narrower than the UK king, the UK double makes it more likely you can keep a bedside table on each side in a modest room.
- Easy bedding to find: Double sheets and a 200 x 200cm double duvet fit, which means fitted sheets with deep pockets for the 31cm depth are simple to source.
- A comfortable guest bed for couples: In a spare room, the UK double gives visiting couples proper shared space on a natural lambswool and latex surface without overwhelming a smaller bedroom.
This size suits you if...
You share the bed with a partner and your bedroom sits around our suggested minimum of 2.6m x 2.8m, or you want a spare room bed that visiting couples will find comfortable. It also suits a solo sleeper whose dog or cat likes to claim the foot of the bed.
Consider another size if...
You and your partner both sprawl, or one of you is tall and wants the extra 10cm of length. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

FAQ's
Is a Hypnos Jura UK double big enough for two people?
For most couples, yes. The UK double gives 67.5cm each, which suits two people who sleep fairly still. If you like to spread out, the UK king gives 75cm each, so the UK double gives 7.5cm less each, and the UK king is also 10cm longer.
What room size do I need for a Hypnos Jura double?
We suggest at least 2.6m x 2.8m for the UK double, with around 3m x 3m a comfortable norm once you add bedside tables and a wardrobe. Bear in mind the bed frame adds a little to the 135 x 190cm mattress footprint.
Hypnos Jura UK double vs UK king: which should I choose?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is tight or you want space on both sides of the bed. The UK king needs at least 2.7m x 2.9m by our guidance.
Will a Hypnos Jura double fit up narrow stairs?
At 135cm wide and 31cm deep, the UK double is a substantial, pillowtopped mattress, and handmade pocket spring builds don't fold the way rolled foam does. Measure the turn in your stairs and the landing before ordering, then compare the retailers listed on this page.
What size sheets fit a Hypnos Jura UK double?
Standard UK double sheets in 135 x 190cm fit, and a 200 x 200cm double duvet works on top. As the Jura is 31cm deep, pick fitted sheets with deep pockets so the corners stay put.
