Memory Foam Comfort Layer
A responsive memory foam that gently moulds to your body's contours, which means it absorbs energy and eases built-up pressure at the hips and shoulders. You'll feel a slight cradling on the surface rather than a deep sink.
Mirapocket Spring Support System
1000 individually nested pocket springs (based on the king size, with the count varying pro-rata for other sizes) react independently to your body weight and movement. Silentnight states the zoned support is scientifically proven to help spinal alignment and posture.
Layer details from silentnight.co.uk product page, September 2026.
Key benefits
- 90cm of width each: Two sharers each get 90cm, so the Mirapocket springs rarely have to absorb a partner's movement because it's happening too far away to feel.
- Springs that keep movement local: The individually nested pocket springs react to weight independently, which means the little disturbance that does cross 180cm of mattress mostly stays on their side.
- Space for the whole household: When children wander in at 3am or the dog treats the bed as routine, a 6ft width means everyone still keeps a workable share.
- Fills a larger master properly: In a big period bedroom or a generous new build master, a UK king can look undersized, while the UK super king sits in proportion.
- Memory foam without the premium price: You get the memory foam comfort layer and zoned spring support in the largest standard size, with live prices from the retailers listed on this page.
This size suits you if...
You share the bed every night with a genuinely restless partner and distance matters more to you than any comfort layer, children or pets regularly join you and you'd all like to keep a fair share, or your master bedroom is large enough that a UK king would leave the room looking half furnished.
Consider another size if...
Your bedroom is under the 3m x 2.9m we suggest, or your stairs and landing would make a 180cm-wide mattress a struggle. We'd recommend the UK king instead: 30cm narrower, the same length, and it suits rooms of at least 2.7m x 2.9m.

FAQ's
Is the super king Pocket Essentials 1000 good for couples with a restless partner?
It's one of the better cases for sizing up. The pocket springs already limit how far movement travels, and at 180cm wide with 90cm of space each, most tossing and turning happens too far away to register. If disturbance is your main complaint, the UK super king does more for it than any comfort layer would.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All of that extra width goes into personal space: 90cm each for two people sharing, rather than splitting 150cm. The feel and construction are identical, so the choice comes down to space and room size.
Will a 3m wide bedroom take this mattress in a super king?
Just about. We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable once you add bedside tables and walking room. Before you order, check the practical snags too: door swing, the turn on your landing, and whether 180cm of mattress will make it upstairs.
Is the Silentnight Pocket Essentials 1000 super king big enough for a family sharing?
Yes, within reason. At 6ft x 6ft 6in it's the size parents tend to land on when young children appear in the night, because a child in the middle still leaves both adults usable space. A large dog at the foot of the bed is similarly easy to accommodate. In a UK king, the same arrivals squeeze everyone.
Where can I buy this mattress in a UK super king?
Compare the retailers listed on this page. The prices shown are updated as retailers change them, so it's worth checking back rather than assuming today's price holds. Availability at this size can be thinner than for the UK double or UK king, so if you see it in stock at a price you like, that's meaningful.
