Key benefits
- 90cm each, every night: Two people sharing get 90cm each, so a partner who turns, stretches or steals the duvet becomes far easier to sleep through.
- Distance plus roll-together control: The Miracoil system is designed to reduce roll-together, which matters less at this width but still helps when one of you shifts near the middle.
- Room for children and pets: If little ones wander in around 3am, or a large dog treats your bed as routine, a super king means everyone keeps a workable share.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK king and the same length, a difference you feel every night you share.
- Pillow top comfort at scale: The hand-tufted pillow top with memory foam beneath gives cushioned, medium firm support across the full 180cm, with zoned springs firmer where your body needs it.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, children or pets regularly join you and a king already feels crowded, or you have a large master bedroom where a smaller bed would look lost. Restless couples in particular get the benefit here: with 90cm each, distance does what no comfort layer can.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you sleep alone and would rather not stretch to bigger bedding. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
What are the dimensions of the Silentnight Miracoil Pillow Top super king?
This size measures 180 x 200cm, which is 6ft x 6ft 6in. It's the largest size UK retailers stock as standard, giving two people sharing 90cm each. Measure your room before ordering: we suggest at least 3m x 2.9m so you can still open drawers and walk around comfortably.
Is the super king Silentnight Miracoil good for a restless partner?
Yes, and largely because of the width. With 90cm each, most movement simply happens too far away to wake you. The Miracoil zoned springs are also designed to reduce roll-together, so on the occasions you do drift towards the middle, you're less likely to feel every turn.
How much bigger is the UK super king than the UK 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 whole point: it turns a comfortable bed for two into one where a child or dog can join you without anyone hanging off the edge.
Is the Silentnight Miracoil super king a good choice for families?
It's one of the better uses of this size. If children wander in during the night, the 180cm width means the adults still get a reasonable share rather than clinging to the edges. The medium firm feel also holds up well with extra, lighter bodies on the surface.
Where can I compare prices for the Silentnight Miracoil Pillow Top super king?
Right here. The prices shown on this page are pulled from retailers stocking this exact size and updated as they change them, so you're comparing live figures rather than last week's. It's worth checking back before you buy, because pricing on larger sizes tends to move around.
