Key benefits
- Distance from a restless partner: With 90cm each, a partner who turns all night is further away, and the sink-in memory foam softens the movement that does reach your side.
- Room when children climb in: When a small child wanders in at night, the UK super king leaves enough width that neither adult ends up clinging to the edge.
- Edges you will actually use: Silentnight's parallel spring design aims for edge-to-edge space, which matters more on a 180cm surface where sleepers spread right out to the sides.
- In proportion with a large room: In a period property or a generous master bedroom, the UK super king sits in scale with the room, where a UK king can look slightly undersized.
- Space for a large dog: If a large dog sleeps on the bed every night, the extra 15cm each over a UK king gives the dog a spot without squeezing either of you.
This size suits you if...
You share the bed with a partner who moves a lot, young children or a large dog regularly join you overnight, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or your stairs and landing are tight. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for that size.

FAQ's
What are the dimensions of the Silentnight Portchester pillow top UK super king?
The UK super king measures 180 x 200cm, which is 6ft x 6ft 6in, and it is 27cm deep. That gives two people sharing 90cm of width each, the most of any UK size this mattress comes in.
How much bigger is a UK super king than a UK king Portchester mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. For a couple, that means 15cm more width each. It sounds modest, but if your partner is a restless sleeper or a child often joins you, those extra centimetres are where the difference shows.
What size bedroom do I need for a UK super king Portchester?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once bedside tables and a wardrobe are in. In a loft conversion, the slope of the ceiling usually decides which wall the bed can go against, so measure the full-height wall before you choose this size.
Will a super king pocket spring mattress fit through my door and up the stairs?
A 180cm-wide mattress has to clear every door swing and landing turn on the way to the bedroom. Measure the tightest corner and the height of the stairwell first, then compare the retailers listed on this page and ask each one how the mattress arrives.
What bedding fits a Portchester super king mattress?
You'll need UK super king fitted sheets and a 260 x 220cm duvet. At 27cm deep with a pillow top, choose deep-fitting sheets so the corners stay put. Super king bedding costs more than smaller sizes, so factor a full set into your budget alongside the mattress.
