Layer Details
- Cover. A knitted, microquilted soft-touch cover, which means a slightly cushioned, cosy surface the moment you lie down. It's designed for enhanced airflow and breathability, so warmth doesn't build up against your skin.
- Comfort Layer. Eco Comfort Fibre fillings that are 100% sustainable and made from recycled materials. They offer cooling and breathability, so you get cushioning without the heat retention some foams can bring.
- Support System. 1000 individual Mirapocket springs, each encased in its own fabric pocket and strengthened by polyester walls. Because each spring responds independently to your body shape, you get pressure relief where you sink and support where you don't.

- Room to be ignored: With 90cm each for two people sharing, a partner who turns all night becomes far easier to sleep through, and distance does more than any comfort layer can.
- Independent springs across a wide bed: The 1000 Mirapocket springs move individually, which means movement on one side of a 180cm-wide surface transfers less to yours.
- Space for night-time visitors: If children or a large dog treat your bed as theirs, the super king's extra width means everyone keeps a fair share rather than someone clinging to an edge.
- Breathable under more bodies: The Eco Comfort Fibre fillings and airflow-focused cover matter more here, since a bed shared by three or four generates noticeably more warmth.
- A big-brand big bed without the big spend: Silentnight's entry-level pricing makes this one of the cheaper ways into a super king; compare the retailers listed on this page for the current lowest.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and you've decided distance is the fix, or children and pets regularly join you and a UK king already feels crowded. Your bedroom should comfortably clear our suggested minimum of 3m x 2.9m, with a larger master feeling more in proportion.
Consider another size if...
Your room falls short of the 3m x 2.9m we suggest for a UK super king, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs a room of at least 2.7m x 2.9m.

Will the Mirapocket 1000 super king feel different from the smaller sizes?
The feel is the same: medium firmness, 1000 Mirapocket springs and Eco Comfort Fibre fillings across every size. What changes is how the bed behaves when shared. Across a 180cm width, each sleeper sits over their own set of independently moving springs, so a partner shifting position disturbs you less than on a narrower mattress.
Is the Silentnight Mirapocket 1000 super king big enough for a family?
It's the most realistic standard size for it. At 180 x 200cm you get 90cm each for two people sharing, which leaves genuine room when a child wanders in during the night or a dog settles at the foot. A UK king can work occasionally; the UK super king makes it comfortable as a routine.
What room size do I need for this super king mattress?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling right, leaving space to walk both sides and open drawers. In a period property or a large new build master, a UK king can look undersized, and this is the size that fills the room properly.
Can I get the Mirapocket 1000 super king upstairs easily?
A 180 x 200cm pocket spring mattress is an awkward carry, so measure your stairwell, landing turns and door swings before ordering. Owners have mentioned the lack of handles on this mattress, which makes manoeuvring a bed this size a two-person job at minimum. If access is tight, check with the retailer about delivery to room.
Is the super king the cheapest way to get a bed this size?
The Mirapocket 1000 sits at the entry-level end of Silentnight's range, so it's one of the more affordable UK super kings from a recognised brand. Do budget for the bedding too: super king sheets and a 260 x 220cm duvet cost more than smaller sizes. Prices shown on this page are updated as retailers change them.
