Layer Details
- Cool-to-touch sleep surface. The UltraGel cool-to-touch comfort layer uses hyper-conductive technology woven into the surface fabric, which means an instant cooling effect when you get into bed. It's the layer doing the most work for hot sleepers.
- Gel-infused layer. Beneath the surface sits a gel-infused layer that responds to your movements as you shift in the night. Silentnight states it's five times more breathable than standard memory foam, so heat has somewhere to go rather than building up around you.
- Support System. The base holds 2000 Mirapocket springs that move independently, which means pressure relief tailored to your shape rather than the whole surface dipping. The zoning is, per Silentnight, scientifically proven to improve spinal alignment and posture.
Layer details from silentnight.co.uk product page, September 2026.
- 90cm each, every night: Two people sharing get 90cm each, which means a restless partner can turn, stretch and fidget without ever crossing into your half.
- Springs that keep disturbance local: The 2000 Mirapocket springs move independently, and across 180cm of width that isolation has real distance to work with, so movement rarely reaches you.
- Room for night-time visitors: When a child or the dog appears at 3am, a 6ft x 6ft 6in surface absorbs the extra body without anyone perching on an edge.
- Cooling that two sleepers don't overwhelm: Two bodies generate real heat, and the cool-touch gel surface has more area to spread it across than any smaller size offers.
- Gentle feel with space to sink: The medium/soft feel invites a bit of sink, and with 90cm each you can settle into your own dip without rolling towards your partner's.
- A proper fit for a large master: At 180cm wide it fills a big bedroom the way a UK king often can't, provided you allow at least 3m x 2.9m.
This size suits you if...
You share the bed every night and want the most sleeping space stocked as standard, your partner is genuinely restless and distance matters as much as spring count, or children and pets treat your bed as theirs too. Your room should measure at least 3m x 2.9m, and a soft-leaning mattress suits you both, since this one is medium/soft rather than firm.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or you rarely have a third body joining you at night. We'd recommend the UK king instead: it's 30cm narrower and the same length, and needs at least 2.7m x 2.9m.

Is a super king worth it for a restless partner?
For this mattress, yes, and the size does much of the work. The 2000 Mirapocket springs already limit motion transfer by moving independently, but 90cm each adds physical distance on top. A medium/soft feel means you sink in slightly, so having your own clear half of a 180cm width stops that sink becoming shared movement.
What room size do I need for the UltraGel 2000 super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once you add wardrobes and walking space. This is our guidance rather than Silentnight's. In a large master or period bedroom the 180 x 200cm footprint looks in proportion where a UK king can seem a little lost.
Will the UltraGel 2000 super king fit up my stairs?
Silentnight doesn't publish delivery dimensions for this size, so measure your stairwell, landing turns and door swings before ordering. A 180 x 200cm mattress at 33cm deep is an awkward carry, and tight turns catch people out more often than the bedroom itself. If access is marginal, check with the retailer before you commit.
Is this super king big enough for co-sleeping with children?
It's the best-placed size in the range for it. With 6ft of width, a small visitor in the middle still leaves both adults usable space, and the independent springs mean a wriggling child disturbs the bed less than you'd expect. The medium/soft surface is forgiving for little ones too, though nothing replaces their own bed long term.
What bedding fits the UltraGel 2000 in a super king?
You'll need super king sheets, and the 33cm depth means standard fitted sheets can struggle, so look for deep or extra-deep versions. A 260 x 220cm duvet suits the 180 x 200cm footprint. Bedding at this size costs more than UK king equivalents, which is a small ongoing expense to budget for alongside the mattress.
