Layer Details
- 90cm of width each: Two people sharing get 90cm each, so a soft, settle-in surface never becomes a squeeze when one of you shifts in the night.
- Distance beats any comfort layer: If your partner fidgets, no foam fully hides it, but 180cm of width puts genuine space between you, which matters more than construction.
- Room for the whole household: When children or a large dog treat your bed as theirs, a super king means everyone keeps a share rather than someone perching on the edge.
- Fills a large master properly: In a period property or generous new build master, a UK king can look undersized against the wall; the super king suits the proportions.
- Softness spread across a big surface: The soft feel lets shoulders and hips sink in, and at this width both sleepers get that give without drifting into each other's dip.
This size suits you if...
You share every night and want the most space any standard UK size offers, your sleep is regularly interrupted by a restless partner or children padding in, or your bedroom is large enough that a smaller bed would look lost. Lighter side sleepers sharing with someone who runs warm do particularly well here: the soft hybrid surface gives at the shoulder while the extra width keeps you apart.
Consider another size if...
Your room is under our suggested 3m x 2.9m minimum, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower but the same length, and needs a smaller room, at least 2.7m x 2.9m by our guidance.

What room size do I need for the Silentnight Lift Replenish super king?
We suggest a minimum of 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add wardrobes and walking space. That's our own guidance rather than Silentnight's. The mattress itself is 180 x 200cm, so measure the wall it will sit against and check the door still swings clear.
Is a soft mattress a good choice in a super king for couples?
Often, yes. The usual worry with a soft feel is disturbing each other as the surface gives, but with 90cm each you're far enough apart that movement matters less. Lightweight side sleepers benefit most. A heavier partner may still find the soft variant lets them sink too far, so check the firmer Lift Replenish options for them.
How much bigger is a super king than a 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 entirely sleeping space: it's the difference between sensing a restless partner and barely noticing them. If your room can take it, the upgrade is mostly about undisturbed sleep rather than legroom.
Can two adults and a child share the super king comfortably?
It's the size we'd point to for exactly that. With 90cm per adult when two share, there's slack for a small visitor at 3am without anyone ending up on the edge. It works for large dogs with a bed-sharing habit too. A soft surface does mean everyone settles in a little, which most families find cosy rather than cramped.
Will the super king Lift Replenish fit up my stairs and round the landing?
A 180cm-wide hybrid is an awkward carry, and hybrids with springs can't be rolled or folded the way some foam mattresses can once unpacked. Measure your stairwell, landing turns and door frames against the 180 x 200cm dimensions before ordering, and check the retailer's delivery access notes via the listings on this page.
