Box top with CoolEase cover
An advanced box top wrapped in a CoolEase cover that Silentnight says draws heat from your body. That means a surface designed to keep you cool and comfortable.
Breathable latex
Latex inside the mattress that relieves pressure on your body as you sleep. Silentnight says it has a natural cooling effect, so you get cushioning without as much heat.
Mirapocket zoned support system
Silentnight's zoned pocket spring system, which it describes as scientifically proven to improve spinal alignment and posture. It gives different parts of your body support where it's needed.

Key benefits
- Distance from a restless partner: At 90cm each, you get 15cm more per person than on the UK king, so a stray elbow or a 3am turn is less likely to reach your side.
- Room when the family joins in: When a child pads in after a bad dream or a large dog settles at your feet, the 180cm width lets both adults still lie flat instead of perching on the edges.
- Less shared heat: Silentnight says the CoolEase cover draws heat from your body, and on a UK super king there's enough gap between you that a partner's warmth adds little to it.
- Zoned support on each side: The Mirapocket zoned springs are designed to support different parts of your body, and each of you gets your own generous strip of that zoning.
- In proportion in a large room: In a period house or a big master bedroom, the UK super king fills the floor sensibly, where a UK king can look slightly lost against the wall.
This size suits you if...
Your partner moves enough to wake you most nights, or children and a large dog join you often enough that space runs out, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room falls short of 3m x 2.9m, or the stairs and landing are tight. We'd recommend the UK king instead: it's the same length and we suggest at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on the Silentnight Relieve 3000 UK super king?
Two people sharing get 90cm each. That's 15cm more per person than the UK king, which gives 75cm each, and 22.5cm more per person than the UK double. If your partner fidgets, those extra centimetres are what keep their movement on their own side of the bed.
What size bedroom do I need for a UK super king mattress?
We suggest allowing at least 3m x 2.9m, and around 3.5m x 3.2m tends to feel comfortable once bedside tables go in. In a loft conversion, the sloping ceiling usually decides which wall the bed can sit against, so measure the full-height section of floor rather than the whole room.
Is a super king big enough for two adults and a child?
It's the most practical size for it. At 180cm wide, the UK super king is 30cm wider than the UK king, so a small child in the middle still leaves both adults some room to stretch. Silentnight doesn't publish a firmness for this mattress, so judge comfort from owner feedback before you buy.
Should I get the Relieve 3000 in a UK king or UK super king?
Both are 200cm long, so the only difference is width: the UK super king is 30cm wider. Choose it if a partner, child or dog regularly crowds you. If your room is nearer our suggested 2.7m x 2.9m for the UK king, the narrower size will leave you space to walk around the bed.
What should I check before ordering a UK super king mattress?
Measure how the bedroom door swings and whether a 6ft x 6ft 6in mattress will make the turn on your landing. Budget for bedding too: you'll need super king sheets and a 260 x 220cm duvet. Once the measurements work, compare the retailers listed on this page for this mattress in a UK super king.
