Sleeping surface
An unbleached cotton and viscose sleeping surface, which means a breathable, natural feel directly under you. No bleaching keeps the processing gentler.
Wool filling
16.3kg of pure British wool per 150cm gives a soft, cushioned feel over the springs. Wool also helps regulate temperature, so it works well across seasons.
Support system
ReActivePro 6-Turn Pocket Springs adapt to your shape individually, which means support where you need it and less partner disturbance. Triple Edge Protection stitches higher-tension springs into the edges for a firmer, more usable perimeter.

Key benefits
- Less disturbance across a wider bed: The ReActivePro pocket springs respond individually, and at 150cm wide there's more distance between you, so an early alarm on one side travels less to the other.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping diagonally or hanging their feet off the end.
- Usable edge to edge: Triple Edge Protection stitches firmer springs into the perimeter, so the full 150cm width is genuinely sleepable rather than shrinking once you avoid the sides.
- Wool comfort at proper scale: The 16.3kg of British wool per 150cm means the full king width carries the same cushioned, breathable surface, useful when two warm bodies share one bed.
- Room for a third party: If a dog treats your bed as its own, the extra width over a double means it can claim its patch without either of you losing yours.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, especially if one of you keeps different hours and climbs in or out while the other sleeps. Or one of you is around six foot and needs the 200cm length as much as the width. Your room should measure at least 2.7m x 2.9m to take it comfortably.
Consider another size if...
Your bedroom falls under our suggested 2.7m x 2.9m minimum, or you sleep alone and rarely spread out. This mattress is sold in the UK king only, so if the size doesn't fit your room or your needs, a different model is the better route.

FAQ's
How much space does each person get on a UK king Hypnos Wool Origins 6?
Two people sharing get 75cm of width each across the 150cm mattress. The pocket springs adjust to each sleeper independently, so that space feels like your own: your partner's movement on their 75cm carries less across to yours than it would on a traditional open-coil bed.
Is the UK king Wool Origins 6 long enough for someone over six foot?
At 200cm, the UK king version measures 6ft 6in in length, which gives a six-footer roughly a head of clearance. That's 10cm more than a UK double, and for many taller sleepers the length is the real reason to size up, with the extra width a bonus.
Will a king size Wool Origins 6 fit in a new build master bedroom?
Often, but measure first. New build masters can feel smaller than the floor plan suggests once wardrobes and bedside tables go in. We suggest at least 2.7m x 2.9m for a UK king, and more if you want to open drawers without shuffling sideways around the bed.
Does the wider king size reduce partner disturbance on this mattress?
It helps in two ways. The pocket springs compress individually, so movement transfers less through the mattress itself, and the 150cm width adds physical distance between you. If one of you gets up early or shifts position through the night, both factors work in your favour.
Can you sleep near the edge of the king size Wool Origins 6?
Yes. Triple Edge Protection uses higher-tension springs around the perimeter, so the edge stays supportive rather than tipping you off. On a shared UK king that matters: it means the 75cm each of you gets is usable right to the side, and sitting on the edge to dress feels stable.
