Layer Details
Pure Belgian Damask Cover
A breathable Belgian damask fabric tops the mattress. It lets air move through the sleep surface, which helps the natural fillings below do their temperature work.
Wool
Wool gives a soft, cushioned feel, which means gentle give at the surface before you reach the springs. It suits those who prefer a traditional, natural mattress.
Cotton
Cotton helps regulate body temperature through the night. It also adds a degree of support alongside its natural comfort.
eOlus™ Fibres
These fibres offer resilient body support while letting air and moisture pass through easily, so you get a soft, foam-like feel without the heat retention foam can bring. Made without harsh chemicals, the fillings are 100% recyclable with no end-of-life disposal issues.
ReActive™ 8-Turn Pocket Springs
Each spring has 8 turns and works independently, sensing the exact comfort and support needs of you and your partner. In practice that means vertical pressure is spread smoothly, giving total spinal and body support.

Key benefits
- Genuine distance from a fidgety partner: With 90cm each, movement on one side rarely reaches the other, and the ReActive 8-turn pocket springs respond independently so it isn't transferred through the mattress either.
- Space for the whole household: When children or a large dog wander in at night, 180cm of width means everyone still gets a workable share rather than someone perching on an edge.
- Different weights, both supported: Each pocket spring senses the sleeper above it, so a lighter and heavier partner spread across this width each get support suited to them.
- Cool sleeping at full width: Wool, cotton and breathable eOlus fibres regulate temperature across the whole 180cm surface, useful when three bodies rather than two end up sharing the bed.
- Fills a larger master properly: In a period property or generous new build master, a UK king can look undersized; at 6ft x 6ft 6in, this fills the room without apology.
This size suits you if...
You share every night and want the most space a standard UK size offers, your partner is genuinely restless and distance matters more than any comfort layer, or children and pets treat your bed as theirs too. Your room is at least 3m x 2.9m, and around 3.5m x 3.2m if you'd like it to feel comfortable rather than merely fitted.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m minimum, or landing turns and door swing make a 180cm mattress a squeeze. 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
What room size do I need for a super king Hypnos Natural Luxury?
Allow at least 3m x 2.9m, which is our own guidance rather than the brand's. Around 3.5m x 3.2m feels more comfortable, leaving space to walk round both sides and open drawers. If your room is smaller, the UK king needs at least 2.7m x 2.9m and gives up 30cm of width, nothing in length.
Is the Hypnos Natural Luxury super king good for restless couples?
It's one of the better cases for this size. You get 90cm each for two people sharing, so most movement simply happens too far away to wake you. The ReActive 8-turn pocket springs also work independently, meaning what motion does occur isn't carried across the mattress the way a connected spring unit would.
Will a super king mattress cope with kids climbing in?
At 180 x 200cm there's room for a child, or a large dog, without pushing either adult to the edge. The pocket springs respond to each body separately, so a light child and a heavier adult are each supported on their own terms. Bear in mind you'll be buying super king sheets, which cost more than king bedding.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. That extra width is where the value sits for couples: it takes you from a decent shared bed to 90cm each. The construction is identical in both, so you're choosing on space and room size alone.
