Key benefits
- 90cm each for two: Each of you gets the full width of a UK single, so a partner who fidgets, kicks or gets up early is far easier to sleep through.
- Space when the family piles in: If a child arrives at 3am or the dog has its own spot by your feet, the extra width means nobody ends up clinging to the edge.
- Edges you can actually sleep on: Hand-sewn side-stitching runs along the border, which means the outer strip of all 6ft of width stays supportive rather than sagging when someone lies near it.
- No flipping a very large mattress: The Iona is single sided with a no-turn design, which matters at 180 x 200cm because flipping something this size is a two-person wrestle you can skip.
- Fills a generous room properly: In a period house or a large master bedroom, a UK king can look a little lost, while the UK super king suits the scale of the space.
This size suits you if...
You share the bed every night and one of you moves a lot, or young children and pets regularly end up joining you. It also suits you if your bedroom comfortably clears 3m x 2.9m and you want natural fillings across the widest standard UK bed.
Consider another size if...
Your bedroom is under 3m x 2.9m, or you only share occasionally. We'd recommend the UK king instead, which is the same length and needs at least 2.7m x 2.9m.

FAQ's
Is the Hypnos Iona super king big enough for two adults and a child?
For a child who wanders in during the night, yes. Two adults get 90cm each on the UK super king, so a small child can settle between you without anyone being pushed to the edge. If it happens most nights rather than occasionally, the extra width over the UK king is where you will feel the difference.
How much bigger is the Hypnos Iona super king than the king?
The UK super king is 30cm wider than the UK king, and both are 200cm long. Shared between two people, that gives 15cm more each: 90cm on the UK super king against 75cm on the UK king. You gain width only, so taller sleepers get no extra legroom by sizing up.
What size room do I need for a Hypnos Iona super king?
We suggest at least 3m x 2.9m for the UK super king, and around 3.5m x 3.2m if you want bedside tables and space to walk round comfortably. In a loft conversion, measure the full-height floor rather than the whole footprint, because a sloping ceiling often decides which wall the bed can go against.
Will a Hypnos Iona super king fit through my door and up the stairs?
At 180 x 200cm and 27cm deep, this is a large, solid piece to manoeuvre. Measure the narrowest doorway, any tight landing turn and the space a bedroom door needs to swing open before you order, then compare the retailers listed on this page once you know it will go in.
What bedding do I need for a Hypnos Iona super king?
You'll need super king fitted sheets with pockets deep enough for a 27cm mattress, plus a 260 x 220cm duvet. Super king bedding costs more and is a little harder to find in shops than UK king sets, so factor that in if you are replacing everything at once.
