Layer Details
Certified British wool
Layers of British wool traceable to assured farms and certified to the Responsible Wool Standard. Wool helps regulate temperature and moisture, which should keep you more comfortable if you tend to run warm.
Recycled eOlus and cotton comfort layers
Beneath the wool sit comfort layers of recycled eOlus fibres and responsibly sourced cotton. They add extra cushioning between you and the springs, giving the medium feel a softer, more natural touch.
Layer details from mattressman.co.uk and solentbeds.co.uk product pages, October 2026.
Key benefits
- Real distance from a restless partner: With 90cm each for two people sharing, most of the tossing and turning happens too far away to wake you.
- Pocket springs that keep movement local: The springs compress independently, which means a partner shifting on their side of a 180cm-wide bed sends very little of it across to yours.
- Room for midnight visitors: When a child pads in at 3am, or the dog claims a corner, there's enough width for everyone to keep a workable share.
- Edges you can actually use: Triple Edge Protection™ suggests reinforced sides, which matters more at this size because a shared bed with children in it pushes adults towards the perimeter.
- Extra width without extra length: The UK super king is 30cm wider than the UK king but the same length, so you gain sprawl without needing a longer wall.
This size suits you if...
You share the bed every night and want proper separation from a partner who moves around, children or a large dog regularly join you before morning, or your bedroom is generous enough that a UK king would look undersized against the wall. Allow at least 3m x 2.9m of floor space, with more feeling comfortable once wardrobes and bedside tables go in.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king, or you rarely share the bed. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a super king Hypnos Legacy 1?
Two people sharing get 90cm each, the widest personal allowance of any standard UK size. Because the Legacy 1 uses pocket springs that compress independently, that width does double duty: your partner is further away, and what movement they do make travels poorly across the surface.
Will the Hypnos Legacy 1 super king fit in my bedroom?
The mattress itself is 180 x 200cm, and we suggest a room of at least 3m x 2.9m so you can still open drawers and walk round the bed. Before ordering, check the route in too: door swings, landing turns and tight stairs catch people out at this size.
Is the super king worth it over the king for this mattress?
If a restless partner is your main complaint, yes. The UK super king is 30cm wider than the UK king at the same length, and at a medium tension that extra distance does more for undisturbed sleep than any comfort layer could. If your room is under 3m wide, the UK king is the sensible call.
Is the Hypnos Legacy 1 super king good for families sharing with children or pets?
It's well suited to it. The 6ft width means a wandering child or a large dog can join without pushing an adult to the edge, and the reinforced sides help when someone does end up sleeping there. The medium tension is a reasonable middle ground for different weights sharing one surface.
Where can I buy the Hypnos Legacy 1 in a super king?
Compare the retailers listed on this page, where prices are updated as retailers change them. Availability shifts, so it's worth checking back if this size shows limited stock, and confirming delivery access for a mattress this large before you order.
