Layer Details
- ActiveBreathe layer. This comfort layer feels like memory foam but is ten times more breathable, which means contouring comfort without the overheating foam is known for. If you tend to sleep warm, this is the feature to pay attention to.
- Mirapocket® spring system. Silentnight's Mirapocket® system uses 800 pocket springs in the king size. Each spring moves independently, so the mattress responds to your shape and reduces the ripple effect when a partner shifts position.
- Eternity layer. The base Eternity layer gives the mattress extra stability and long lasting resilience. In practice, that means the firm feel should hold up rather than softening quickly.

- 90cm of width each: Two people sharing get 90cm each, so you can both stretch out without negotiating over the middle of the bed.
- Distance plus independent springs: The Mirapocket® springs respond to each sleeper separately, and at this width a fidgeting partner is simply further away, which matters more than any comfort layer.
- Room for the whole household: If children or a large dog treat your bed as theirs most nights, a 6ft width keeps everyone with a workable share.
- Firm support across a big surface: The Eternity base layer adds stability and resilience, so the firm feel should hold its shape across the full 180cm rather than dipping where you sleep.
- Breathability for two warm bodies: Two sleepers generate more heat than one, and the ActiveBreathe layer offers memory foam comfort without the swelter foam is known for.
This size suits you if...
You share every night and a UK king still feels like a compromise, your partner is genuinely restless and you want distance rather than hoping springs fix it, or children and pets regularly join you and everyone needs their own patch. It also suits a large master or period bedroom where a smaller bed would look lost, provided you can allow at least 3m x 2.9m of floor space.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or the extra bedding cost and awkward stair carry put you off. 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.

What room size do I need for the Silentnight Revitalise Refresh 800 super king?
We suggest a room of at least 3m x 2.9m. That's our own guidance, not Silentnight's, and it's the minimum for walking round the bed and opening drawers. Check door swing and landing turns before ordering too: at 180 x 200cm, this is the size where a tight staircase starts to bite.
How much space do two people get on the super king?
90cm each for two people sharing, which is the same width per person as a UK single. In practice that means a partner can turn over, sprawl or get up early without crossing into your half, and the Mirapocket® springs reduce the ripple that does travel across.
Is the Silentnight Revitalise Refresh 800 super king the same length as the king?
Yes. The UK super king and the UK king are the same length; the difference is width, with the UK super king 30cm wider at 180cm. If you're tall, sizing up buys you elbow room rather than legroom, so choose based on how much sideways space you want.
Is this super king a good choice if children climb in at night?
It's one of the better setups for it. A 6ft width means a child between you still leaves both adults a reasonable share, and the firm feel keeps the surface stable rather than everyone rolling into a dip. Lightweight children lying on their sides may find it a little unyielding, though most treat it as a visit rather than a permanent bed.
How big is the Silentnight Revitalise Refresh 800 in a super king?
It measures 180 x 200cm, which is 6ft x 6ft 6in. That makes it 45cm wider and 10cm longer than the UK double, and 30cm wider than the UK king. It's the largest size this mattress comes in, and the largest stocked as standard in the UK.
