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
- A full 90cm each: Two adults get 90cm each, the width of a UK single apiece, so a partner who turns over all night is far less likely to wake you.
- Room for night-time visitors: When a small child climbs in at 3am, a UK super king still leaves both adults a usable strip rather than a narrow ledge at the edge.
- Wider than the UK king, same length: It is 30cm wider than the UK king and exactly as long, so all the gain goes into width, giving 15cm more each for two sharing.
- Space for a large dog: If a big dog sleeps on the bed as a matter of routine, the 6ft x 6ft 6in surface lets it stretch out without pushing either of you aside.
- Suits a large master bedroom: In a high-ceilinged period room or a generous new build master, a 31cm deep pillowtop at this width fills the space in proportion where a UK king can look a little small.
This size suits you if...
You share the bed with a partner who fidgets, kicks or gets up in the night, or your children and pets regularly end up joining you. It also suits you if your bedroom comfortably clears our suggested 3m x 2.9m minimum and you want the widest bed it can take.
Consider another size if...
Your bedroom is tight or you sleep alone. We'd recommend the UK king instead, which is the same length and needs at least 2.7m x 2.9m.

FAQ's
Is a Hypnos Jura UK super king big enough for two adults and a child?
For most families, yes. Two adults get 90cm each, so a small child tucked between you still leaves both of you a reasonable share. If an older child or a large dog joins most nights, it will feel busier, but a UK super king is the widest size the Jura comes in, so there is no bigger option to step up to.
How much bigger is the Hypnos Jura super king than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. For a couple sharing, the UK super king gives 15cm more each. If you are tall, sizing up won't add any length, so choose the UK super king for width alone.
What size bedroom do I need for a Hypnos Jura UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once bedside tables and a wardrobe are in. In a loft conversion, floor area alone can mislead: measure where the ceiling slope begins, because you need full headroom along the side you get in and out of.
Will a Hypnos Jura super king fit through my door and up the stairs?
Measure before you order. At 180 x 200cm and 31cm deep with a pillowtop, a UK super king Jura is a large, deep mattress, so check door widths, any tight landing turns and the way your bedroom door swings open. Once those measurements look workable, compare the retailers listed on this page.
What bedding do I need for a Hypnos Jura super king?
You'll need super king sheets and a 260 x 220cm duvet. The Jura is 31cm deep, so choose fitted sheets with deep pockets, as standard ones may not tuck under a mattress of this depth. Super king bedding also tends to cost more than UK king sets, so budget for that alongside the mattress.
