Layer Details
Belgian damask cover
A Belgian damask viscose sleep surface that is naturally fire resistant and free of FR chemicals. If you'd rather avoid added flame-retardant chemicals against your skin, that's a plus.
Upholstery layers
Himalayan Allo, silk-like Kapok, cotton and recycled eOlus fibres enclose the spring system. These natural fibres sit between you and the springs, giving a softer, more cushioned feel on top of the support below.
ReActivePro pocket springs
7-turn ReActivePro pocket springs with Triple Edge Protection. Each spring works on its own, so the mattress can respond to different parts of your body, and the protected edges are there to help the sides hold their shape.
British wool layer
The final layer is 6kg of certified British wool (RWS) that acts as a temperature regulator. It helps manage heat through the night, so you're less likely to feel too warm or too cool.

Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, so you can both stretch out without negotiating the middle ground every night.
- Distance plus independent springs: Pocket springs already limit how much movement travels across the bed, and at this width a fidgety partner is simply further away too.
- Room for night-time visitors: If children or a large dog find their way in most mornings, this is the one size where everyone still gets a fair share.
- Fills a large master properly: In a big period bedroom or a generous new build master, a UK king can look undersized, while the UK super king sits in proportion.
- Same length as the UK king: At 200cm long, sizing up from the UK king adds width only, so taller sleepers lose nothing by going bigger.
This size suits you if...
You share the bed every night and want the most space a mainstream UK size offers, your children or pets regularly join you and a UK king has started to feel crowded, or your bedroom is large enough that a smaller mattress would look lost in it. Allow at least 3m x 2.9m of floor space, with something nearer 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your room falls short of the 3m x 2.9m we suggest, or you'd rather not pay super king bedding prices. The UK king is 30cm narrower and the same length, and needs only 2.7m x 2.9m, so we'd recommend that instead.

FAQ's
How much space do two people get on the Hypnos Legacy 2 super king?
90cm each for two people sharing, which is the same width per person as a UK single. Combined with the pocket sprung core, which responds to each sleeper individually, that means you can sleep close to the edge of your own half without feeling every shift your partner makes.
Is the super king Hypnos Legacy 2 good for restless partners?
It's the strongest choice in the range for this. Pocket springs move independently, so motion doesn't ripple across the mattress the way it does on an open coil, and the 180cm width puts real distance between you. No comfort layer beats simply being further away from the fidgeting.
What room size do I need for the Hypnos Legacy 2 in a UK super king?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels right if you want bedside tables on both sides and space to walk around the bed. Before ordering, check the practical points too: door swing, any tight turns on the landing, and the stairs themselves.
How much bigger is the super king than the UK king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. So the decision is purely about width and room size: the UK king needs at least 2.7m x 2.9m by our guidance, while the UK super king needs 3m x 2.9m.
Is this size worth it for a family that shares the bed?
If children wander in during the night, or a large dog treats the bed as its own, the extra 30cm of width over a UK king is what stops one adult being pushed to the edge. At 180cm wide, it matches the footprint of two UK singles side by side.
