Layer Details
- Cover. An unbleached, chemical-free cotton cover in Belgian damask, which means a soft, breathable sleeping surface without harsh treatments. Damask is a tightly woven fabric that wears well over time.
- Comfort fillings: British wool. Insulating British wool cushions the whole body, which means gentle pressure relief rather than the sink-in feel of memory foam. Wool also helps keep the surface temperate.
- Comfort fillings: cotton. Cotton wicks away excess moisture and works alongside the wool to regulate temperature. In practice, that means a drier, more comfortable feel in both summer and winter.
- Comfort fillings: Solotex and eOlus fibres. Recycled Solotex and eOlus fibres add to the cushioning while promoting airflow. That extra breathability matters most if you tend to overheat at night.
- Support system: ReActive pocket springs. A core of ReActive 8-turn pocket springs supports key areas of the body. Each turn lets the spring react faster to your movements, which means the mattress adjusts as you change position rather than lagging behind.

- Real distance from a restless partner: With 90cm each for two people sharing, movement on the other side of the bed happens a long way from you.
- Pocket springs that move independently: The ReActive 8-turn pocket springs respond to each sleeper separately, which means a partner turning over at 3am is less likely to travel across to your side.
- Space for the whole household: When children or a large dog treat your bed as theirs, the 180cm width keeps everyone from being squeezed to the edge.
- Firm support across a big surface: The firm feel stays consistent whether you sleep in the middle or near the edge, useful when three bodies spread out across it.
- Cooler sharing, thanks to natural fillings: More bodies means more heat, and the British wool and cotton fillings help the surface stay temperate even with the bed full.
This size suits you if...
You share every night and want the maximum space a standard UK size offers, your partner is a light or restless sleeper and distance matters more than any comfort layer, or children and pets regularly join you and a UK king has started to feel crowded. Your bedroom should measure at least 3m x 2.9m for this size to work comfortably.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king. In that case we'd recommend the UK king instead: it's 30cm narrower but the same length, and needs at least 2.7m x 2.9m.

Will the Hypnos Majesty Ortho Sublime UK super king fit in my bedroom?
The mattress itself measures 180 x 200cm, but you need clearance around it for doors, wardrobes and walking space. We suggest a room of at least 3m x 2.9m for a UK super king, with something nearer 3.5m x 3.2m feeling comfortable. Measure the door swing too; at this width it catches people out.
Is the super king worth it over the king for the Hypnos Majesty Ortho Sublime?
The UK super king is 30cm wider than the UK king, and the two are the same length, so the whole difference is elbow room. If you share with a restless partner, or children and pets join you, that extra width changes how the bed feels every night. If it's just the two of you in a smaller room, the UK king does the job.
How much space does each person get on the super king Hypnos Majesty Ortho Sublime?
90cm each for two people sharing. That's enough for each of you to stretch out, change position and sleep without touching, and the ReActive pocket springs compress under each sleeper individually rather than tilting the whole surface. It's the size we'd point restless couples towards first.
Is the Hypnos Majesty Ortho Sublime super king good for couples with a restless sleeper?
Yes, and for two reasons. The width gives you 90cm each, so a partner who turns constantly does it well away from you. And the 8-turn pocket springs respond to movement locally, which means their tossing is less likely to ripple over to your side than on a smaller, more crowded mattress.
Can a family share the Hypnos Majesty Ortho Sublime UK super king?
It's the standard size best suited to it. At 180cm wide, a child wandering in at night, or a large dog claiming the foot of the bed, still leaves both adults a fair share. The firm feel also helps here: the surface doesn't dip towards the heaviest sleeper, so nobody rolls into the middle.
