Layer Details
Sleep Surface
A naturally hypoallergenic fabric that sits directly against your bedding. It's soft and gentle on the skin, a small comfort if you have sensitive skin or allergies.
Comfort Breathe®
Silentnight describes these fibres as 15x more breathable than standard memory foam, promoting airflow and regulating temperature. In practice, that means less of the heat build-up hot sleepers dread.
2000 Mirapocket Springs
Each of the 2000 springs sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it also limits how much you feel a partner moving.
Protective Layer
This layer disperses pressure from the spring unit across the mattress. The idea is a longer working life, as no single area takes all the strain.
Durable Case
A soft but durable outer case designed to keep the mattress comfortable for years. It holds everything together rather than adding a distinct feel of its own.

Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, so you can stretch out fully without negotiating over the middle of the bed.
- Distance plus 2000 pocket springs: The independent Mirapocket springs already limit motion transfer, and at this width there's physical space between you too, a real advantage with a fidgety partner.
- Room for children and pets: If little ones or a large dog routinely appear in the night, this size means everyone still gets a workable share of the bed.
- Breathability matters more at scale: The Comfort Breathe layer promotes airflow across the whole 180cm surface, so three warm bodies on one mattress feels less clammy than you'd expect.
- 30cm wider than a UK king: That extra 30cm over the UK king is the difference between a comfortable share and true sprawl, though both sizes are the same length.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your partner shifts around constantly and you'd rather have distance as well as pocket springs between you, or children and pets treat your bed as theirs and your current size can't absorb the invasion. It also suits a large master bedroom where a UK king would look a little lost.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for this size, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
How much space does each person get on the super king Silentnight Eco Comfort Breathe 2000?
Two people sharing get 90cm of width each. Combined with the 2000 Mirapocket springs, which respond independently on each side, that means one of you turning over barely registers for the other. It's the size we'd point restless couples towards for this mattress.
What room size do I need for the Silentnight Eco Comfort Breathe 2000 in a UK super king?
We suggest a minimum of 3m x 2.9m, and that's our guidance rather than Silentnight's. The mattress itself is 180 x 200cm, so anything smaller leaves you squeezing past the bed to reach a wardrobe. Measure with door swing and bedside tables in mind before you order.
Is the super king version of this mattress good for families sharing the bed?
Yes, and it's arguably the best case for this size. At 180cm wide there's room for a child who wanders in at 3am without anyone hanging off an edge, and the Comfort Breathe layer helps disperse the extra body heat that comes with more people under one duvet.
Is the UK super king worth it over the UK king for this mattress?
If your room takes it, usually yes. The UK super king is 30cm wider than the UK king and the same length, and that width is what turns a decent shared bed into one where a fidgety partner stops waking you. In a smaller room, the UK king remains the sensible pick.
Does a medium soft mattress work at super king size for two different-weight sleepers?
The width helps here. Each of the 2000 pocket springs moves on its own, so a heavier partner sinking in further doesn't tilt your side, and with 90cm each you're supported by entirely separate areas of the mattress. Heavier back or stomach sleepers may still find the medium soft feel slightly forgiving, whatever the size.
