Why should you choose this mattress?
The Jura is built around natural materials rather than memory foam. Two latex layers provide support, and at least five full fleeces of organic British lambswool sit above the springs, whichever tension you choose. ReActivePro 7-turn pocket springs form the base. The pillowtop adds cushioning on top, and the no-turn construction means you don't need to flip it. Hypnos handcrafts it in the UK, with three layers of traditional side-stitching. It suits anyone who wants a natural, traditional build, although with no published firmness you'll want to check the tension before buying.
Key features & 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.

Best suited for?
Eco-conscious buyers
Natural latex and at least five full fleeces of organic British lambswool replace memory foam, so the comfort and support layers come from natural materials.
Combination sleepers
Two latex layers over ReActivePro 7-turn pocket springs give support from natural materials, which suits people who shift position through the night.
Couples
The pocket spring base and the range from UK double up to super king give two people plenty of room on a cushioned pillowtop surface.
Warm sleepers
Breathable natural fillings like lambswool and latex sit above the springs, which gives a cushioned surface made from natural materials rather than memory foam.
If you want a clearly stated firmness before you buy, this might not be the best choice, as none is published for the Jura. It's also a premium mattress, and as a no-turn pillowtop it can't be flipped. If you prefer the contouring of memory foam, the latex build may feel different.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Hypnos Jura?
Hypnos doesn't publish a firmness for the Jura, so it's hard to say whether it will suit you on feel alone. The pillowtop adds cushioning on top, but check the tension you're choosing before you order.
How deep is the Hypnos Jura?
The Hypnos Jura is 31cm deep. That's a fairly substantial mattress, so it's worth checking that your bed frame and any fitted sheets you plan to use will cope with the depth.
What is the Hypnos Jura made of?
It uses natural latex, organic British lambswool, silk, cotton and a seaweed-infused tick, built over ReActivePro 7-turn pocket springs. There's no memory foam, as latex is used instead.
What sizes does the Hypnos Jura come in?
It comes in a UK single, UK small double, UK double, UK king and UK super king. It's available as Single Tension or Zip & Link, so confirm which version you're choosing.
Does the Hypnos Jura need turning?
No. It has a pillowtop, no-turn construction, so it isn't designed to be flipped. Hypnos also gives it a 10-year guarantee.
