Layer Details
Cover
A damask cover made from breathable Belgian damask fabric. It lets air pass through rather than trapping heat at the surface.
Solotex™ cushioning
Layers of soft Solotex™ cushioning gently cradle the body, which means pressure relief at your hips and shoulders. This is the plush feel you'll notice first.
Wool and cotton fillings
Sumptuous wool fleeces from British sheep on Red Tractor assured farms work alongside responsibly sourced cotton. Together they regulate temperature and wick away moisture, a genuine help for hot sleepers.
eOlus™ comfort pad
An eOlus™ recycled fibre pad enhances resilience and airflow. It helps the comfort layers keep their shape over time.
ReActivePro™ pocket springs
An 8-turn pocket spring system with Triple Edge Protection™, engineered to respond independently to body movements. In practice that means adaptive support tailored to your shape and a firmer, more usable edge.

Key benefits
- 90cm each for two sharing: You each get 90cm of width, which means a partner who turns over half the night is simply too far away to wake you.
- Distance plus independent springs: The ReActivePro™ 8-turn pocket springs absorb movement on their own, and at this width there's physical space between you too, a double layer of undisturbed sleep.
- Room for night-time visitors: When a child pads in at 3am, or the dog treats the bed as routine, everyone still keeps a workable share of the mattress.
- Usable right to the edge: Triple Edge Protection™ keeps the perimeter supportive, so the outer stretch of a very wide bed is proper sleeping space rather than a soft drop-off.
- Wool works harder across a big surface: A shared bed builds heat, and the British wool fillings wick moisture and regulate temperature so two warm sleepers stay comfortable through the night.
This size suits you if...
You share the bed every night and want the most space a standard UK size can give, your children or pets regularly join you and a UK king already feels crowded, or you have a large master bedroom where a smaller bed would look lost. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling more comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for the UK super king, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
Will the Hypnos Purity Luxury Wool super king fit up my stairs?
This is the question to answer before you order. Hypnos delivers it flat rather than rolled, so you're moving a rigid 180 x 200cm mattress in one piece. Measure your stairwell, any landing turns and the bedroom door swing before buying. Tight Victorian staircases and low loft hatches are the usual sticking points at this size.
How much space do two people get on a super king?
90cm each for two people sharing, which is the width the size guide gives for a UK super king. On this mattress that space works with the ReActivePro™ pocket springs, which respond to each sleeper independently, so a partner who fidgets is both too far away and too well isolated to disturb you.
Is the super king worth it over the UK king for this mattress?
The UK super king is 30cm wider than the UK king and the two are the same length, so the question is purely about width and your room. We suggest at least 3m x 2.9m for the UK super king against at least 2.7m x 2.9m for the UK king. If children or pets join you, the extra width is what you'll notice.
Is the Hypnos Purity Luxury Wool super king good for families sharing?
It suits the job well. The width absorbs a wandering child without pushing either adult to the edge, the pocket springs keep small movements from travelling across the bed, and the Triple Edge Protection™ means whoever ends up on the perimeter still gets proper support. The wool fillings help too, since three bodies generate real heat.
Where can I buy the Hypnos Purity Luxury Wool in a super king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. Because this mattress is delivered flat rather than rolled and boxed, it's also sensible to check each retailer's delivery arrangements for a mattress this size before you commit.
