Layer Details
Sleep surface
The surface layer is stitched directly onto the mattress, which gives you a smoother sleep surface with less chance of the top feeling uneven.
Protective layer
This layer spreads the pressure from each spring over the full surface area of the mattress. That helps the mattress last longer and keeps the springs working evenly under you.
Casing
A protective casing surrounds the mattress and keeps the inner layers safe. The Miracoil spring system sits within it, and the springs don't lose height over time.

Key benefits
- Distance from a restless partner: With 90cm each for two people sharing, a fidgeting partner is far enough away that no comfort layer needs to compensate.
- Space when children wander in: A small visitor at 3am is absorbed rather than felt, which is the difference between a disturbed hour and none at all.
- Fills a larger master properly: In a period property or a generous new build main bedroom, a UK king can look lost; the UK super king sits in proportion.
- Room for a dog with a routine: If a large dog treats the foot of the bed as theirs, this size means the humans still sleep comfortably around it.
- The hotel footprint at home: This range trades on hotel-style comfort, and the UK super king is the size those hotel beds are actually built on.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner moves around enough that distance matters more than mattress feel, or children and pets regularly join you and a UK king has started to feel crowded. Your bedroom should be at least 3m x 2.9m, and closer to 3.5m x 3.2m for it to feel comfortable rather than dominated.
Consider another size if...
Your room measures under our suggested 3m x 2.9m, or you sleep alone and the width would go unused. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs a smaller room at 2.7m x 2.9m.

FAQ's
How big is the Silentnight Hotel to Home Support mattress in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That gives two people sharing 90cm of width each, which is the same width each sleeper would get on a standard UK single. It's the largest size this mattress comes in.
Will the UK super king Silentnight Hotel to Home fit in my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables and space to walk around both sides. Measure the door swing and any landing turns too; a mattress this size can be awkward on tight stairs.
Should I get the Silentnight Hotel to Home in a UK king or UK super king?
The UK super king is 30cm wider than the UK king and the same length, so the choice comes down to width and room size. If a restless partner or visiting children are the issue, the extra 30cm makes a real difference. If your room is under 3m wide, the UK king is the safer buy.
Is the super king Silentnight Hotel to Home good for couples with children?
It's the most practical size for it. With 90cm per sleeper there's genuine room to absorb a child who wanders in at night, or a dog that has made the bed part of its routine, without either adult ending up on the edge. Just be aware Silentnight doesn't publish firmness details for this model.
Where can I buy the Silentnight Hotel to Home Support in a UK super king?
Compare the retailers listed on this page, where prices are updated as retailers change them. Availability for this model is more limited than for better documented mattresses, so it's worth checking the listing carefully for construction and firmness details before you commit.
