Layer Details
- Cotton comfort layers. Four layers of cotton sit at the top of the mattress. Cotton is breathable and wicks moisture, which means a cooler, drier feel through the night than synthetic fillings tend to give.
- ReActive 6-turn pocket springs. The support core uses Hypnos's ReActive 6-turn pocket springs, each one working independently. That means the mattress contours to your body and limits motion transfer across the bed.
Layer details from mattressman.co.uk product page, September 2026.
- 90cm of width each: Two people sharing get 90cm each, which means a fidgety partner can turn over all night without pushing you towards the edge.
- Independent springs across a wide bed: The ReActive 6-turn pocket springs move individually, so at this width movement on one side barely registers on the other.
- Room for the whole household: When children or a large dog treat your bed as theirs, the 180cm width means everyone still gets a workable share.
- Firm support that suits sharing: A firm surface stays level rather than dipping towards the heavier sleeper, which matters more the wider the bed gets.
- Cooler with company: Four cotton layers wick moisture and breathe, helpful when two adults, and sometimes more, are warming the same mattress.
This size suits you if...
You share every night and want distance from a restless partner rather than hoping a comfort layer absorbs the movement, you regularly end up with children or pets in the bed and need the space to make that liveable, or you have a large master bedroom where a UK king would look and feel undersized.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum for this size. 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 Orthos Support 6 super king fit in a 3m wide bedroom?
Just about. We suggest at least 3m x 2.9m for a UK super king, which leaves walking room either side but little more. Around 3.5m x 3.2m feels comfortable, with space for bedside tables on both sides and wardrobe doors that open fully. Measure door swing and any landing turns before you commit.
Is the Hypnos Orthos Support 6 super king good for restless couples?
It's a strong fit. The ReActive 6-turn pocket springs respond individually, so movement doesn't travel far across the bed, and with 90cm of width each there's simply more distance between you. Distance does more for disturbed sleep than any spring system, and this size gives you the most of it.
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. That extra width is the difference between sharing comfortably and sharing with a child or dog in the middle. The UK king needs a room of at least 2.7m x 2.9m, so the step up mainly costs floor space.
Is a firm super king mattress a good idea for families sharing with children?
A reasonable one. The firm surface stays flat under uneven weights, so a small child between two adults doesn't roll into a dip, and the 180cm width means a night-time visitor doesn't push anyone to the edge. Lightweight side sleepers, including older children, may find the firmness a little unforgiving though.
Where can I buy the Hypnos Orthos Support 6 in a UK super king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so they're a better guide than any figure we could print. At this size it's also worth checking each retailer's delivery arrangements, since a 180 x 200cm mattress is an awkward item to get upstairs.
