Layer Details
Sleep surface
A soft cotton sleep surface sits at the top. Cotton is naturally breathable, which means the layer closest to your skin stays comfortable rather than clammy.
Wool fillings
Beneath the cotton sit eight fleeces of wool that regulate body temperature through the night, so you feel warm in winter and cooler in summer. The wool is sustainably sourced and traceable to its origins through Hypnos' partner Red Tractor.
Support system
The base is 1,200 ReActivePro 6-turn pocket springs, which respond to your weight and position to relieve built-up pressure. Triple Edge Protection adds three rows of firmer springs and rod edging around the spring unit, which means a firmer, more usable edge.

Key benefits
- Real distance from a fidgety partner: With 90cm each for two people sharing, most of their tossing happens too far away to reach you in the first place.
- Pocket springs that keep movement local: The 1,200 ReActivePro pocket springs respond to each sleeper individually, so what little movement does travel across this width is absorbed rather than passed on.
- Room for the whole household: If children or a large dog treat your bed as theirs, the 180cm width means everyone still gets a genuine share rather than a sliver.
- Wool that copes with extra bodies: Eight fleeces of wool regulate temperature across the surface, which matters when three warm sleepers share one duvet on a summer night.
- An edge you can actually use: Triple Edge Protection adds firmer springs and rod edging around the perimeter, so the outer inches of this generous width are proper sleeping space, not a slope.
- Meaningfully bigger than a UK king: The UK super king is 30cm wider than the UK king at the same length, and that extra width is where the undisturbed feel comes from.
This size suits you if...
You share the bed every night and want enough width that a restless partner, a child arriving at 3am or a dog with settled habits doesn't shrink your side to nothing, and your bedroom is genuinely large, ideally beyond our suggested minimum of 3m x 2.9m, so the bed sits comfortably rather than dominating.
Consider another size if...
Your bedroom measures under our suggested 3m x 2.9m minimum, or you sleep alone. We'd recommend the UK king instead: it's the same length, and we suggest at least 2.7m x 2.9m of room for it.

FAQ's
What room size do I need for the Hypnos Winslow in a UK super king?
We suggest at least 3m x 2.9m for a UK super king, and that's our guidance rather than the manufacturer's. That allows walking space and drawers that open, though not much more. In a large master or a period property the mattress looks in proportion; in a standard double room it will crowd everything else out.
How much space does each person get on a UK super king Winslow?
90cm each for two people sharing, which is the width of a whole single bed apiece. On this mattress that space matters twice over: the sheer distance means a restless partner rarely reaches you, and the 1,200 pocket springs absorb what movement remains rather than transmitting it across the bed.
Is the Hypnos Winslow super king worth it over the UK king?
If a third body regularly joins you, yes. The UK super king is 30cm wider than the UK king, and both are the same length, so the entire difference goes into elbow room. Couples who sleep soundly side by side may find the UK king perfectly adequate; couples with children, pets or a fidgeter will feel those 30cm every night.
Can children share the Hypnos Winslow super king comfortably?
This is the size where sharing stops being a squeeze. At 180cm wide there's room for a small visitor between you without anyone clinging to an edge, and the Triple Edge Protection means whoever ends up on the perimeter still gets firm support. The wool fillings also help when extra bodies push the bed's temperature up.
Does the Winslow super king suit a loft conversion bedroom?
It can, but measure carefully. A loft room's sloping ceiling usually dictates which wall takes the bed, and at 6ft x 6ft 6in this mattress limits your options more than a smaller size would. Check the usable floor area against our suggested 3m x 2.9m minimum, and check the stair turns before you order.
