Layer Details
- Cover. A cotton-rich cover sits on top. Cotton is breathable, which means it helps the sleep surface stay a little cooler than fully synthetic fabrics.
- Cushion layer. A dense cushion layer provides comfort to an already firm mattress. In practice, that means a touch of give at the surface before you reach the firmer support beneath.
- Spring unit. The spring unit forms the supportive core of the mattress. This is where the firm, orthopaedic-style feel comes from.

- 90cm each for two sharing: That's a full single's worth of width per person, which means one of you turning over rarely disturbs the other.
- Distance handles the restlessness: An extra firm surface won't cradle a fidgety partner, but at this width you're simply too far apart for their movement to reach you.
- Space when the family joins in: A child who appears at 3am, or a dog who considers the bed theirs, can squeeze in without pushing either adult to the edge.
- Firm support across the full 6ft: The pocket spring core delivers the same no-nonsense firmness edge to edge, so neither sleeper ends up on a softer patch.
- Same length as a UK king: At 200cm long (6ft x 6ft 6in overall), taller sleepers get the same legroom as the UK king, with 30cm more width between you.
This size suits you if...
You share the bed every night and want the most space you can buy without going bespoke, your sleep is regularly interrupted by a partner who shifts around, or children and pets treat your bed as their own. You both prefer a properly firm feel, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m, ideally with room to spare for walking round the bed.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or you sleep alone and the extra width would go unused. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

How much space do two people get on the Legend Ortho super king?
90cm each for two people sharing, which is the width of a UK single per person. On an extra firm mattress like this one there's no soft surface to absorb a partner's fidgeting, so that distance does the work: at 90cm apart, most movement simply doesn't reach you.
What size room do I need for the Legend Ortho super king?
We suggest at least 3m x 2.9m. That's our own guidance rather than the manufacturer's, and it's the minimum for the 180 x 200cm mattress plus space to walk around it. If your room is tighter than that, the UK king needs less: we suggest at least 2.7m x 2.9m for 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 sizes are the same length. All the extra goes into width between the two of you, which is what matters if a restless partner or visiting children are the reason you're sizing up. Taller sleepers gain nothing by staying with the UK king.
Is the Legend Ortho super king a good choice if children climb in at night?
Size-wise, yes. At 180cm wide there's genuinely room for a small visitor between two adults without anyone hanging off the edge. The extra firm feel also means a child's weight won't create a dip that rolls everyone toward the middle. Whether they'll find it too firm for a full night is another matter.
Is the super king the same width as two single beds?
Yes, the 180cm width of the UK super king matches two 90cm UK singles side by side. Bear in mind the Legend Ortho in this size is one large mattress rather than two halves, so measure your stairs and landing turns before ordering. The retailers listed on this page will confirm handling details.
