Layer Details
- UltraGel comfort layer. A gel infused foam layer that responds to your movements, which means you get contouring without the slow, sunken feel some foams have. Silentnight says it's 5x more breathable than standard memory foam, so it should run cooler through the night.
- Mirapocket springs. 1000 Mirapocket springs, each held in its own fabric pocket so they respond independently to your body. In practice that means zoned support, better spinal alignment and less motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- The most space you can buy off the shelf: At 180 x 200cm, the UK super king is the biggest size in Silentnight's standard range, with a genuinely generous 90cm each for two people sharing.
- Distance plus pocket springs for restless partners: The 1000 Mirapocket springs respond independently to movement, and at this width your partner is far enough away for their tossing to fade into the background.
- Room for children and pets who join in: When a child wanders in at 3am or the dog claims a corner, a UK super king means nobody ends up clinging to the edge.
- Cooler sleeping across a bigger surface: The gel infused comfort layer, which Silentnight states is 5x more breathable than standard memory foam, matters more when two people share a bed all night.
- A sensible step up from a UK king: The UK super king is 30cm wider than the UK king and the same length, so you gain width where couples actually feel it.
This size suits you if...
You share the bed every night and want maximum distance from a partner who shifts around, your children or a large dog regularly end up in the bed by morning, or you have a large master bedroom where a UK king would look a little lost. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling more comfortable.
Consider another size if...
Your bedroom measures less than our suggested 3m x 2.9m, or you'd struggle to get a 6ft mattress round your landing. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

How much space does each person get on a UK super king Silentnight UltraGel 1000?
Two people sharing get 90cm each, which matches the width of a full UK single per person. Combined with the 1000 Mirapocket springs, which compress independently rather than transferring movement across the bed, that space means one sleeper turning over rarely registers on the other side.
Is the Silentnight UltraGel 1000 in a UK super king good for restless partners?
It is one of the better setups for it. The pocket springs isolate movement so a turn on one side stays on that side, and the sheer width of the UK super king adds physical distance on top. If disturbed sleep is your main reason for upgrading, this size does more for you than any comfort layer could.
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 where couples feel the difference, particularly if children or pets share the bed. It does need more floor space: we suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king.
Does a super king suit families whose children climb in at night?
This is the size we'd point families towards. At 180 x 200cm there's enough room for a small visitor without either adult being pushed to the edge, and the individually pocketed springs mean a wriggling child disturbs the bed less than they would on an open coil design. A large dog with a routine of joining you gets the same benefit.
