Pocket Springs
A unit of 1,000 individually pocketed springs sits at the heart of the mattress. Because each spring is sewn into its own fabric pocket, it compresses independently, which means the mattress contours to your body and cuts down on partner disturbance.

Key benefits
- A full 90cm each: Two adults get 90cm of width apiece, which means you can sprawl or turn over without meeting an elbow halfway across the mattress.
- Distance from a restless sleeper: The 1,000 pocketed springs move independently, and in a UK super king there is simply more mattress between you and a partner who fidgets all night.
- Space for small visitors: If a child climbs in after a bad dream or a large dog has claimed the foot of the bed, the adults still keep a usable share of the width.
- More room than a UK king: You gain 30cm of width over the UK king, or 15cm more each, while the length stays the same, so taller sleepers lose nothing.
- Suits a big master bedroom: In a spacious period room or a large new build master, a UK super king fills the space properly where a smaller bed can look a little lost.
This size suits you if...
You share the bed with a partner whose movement regularly wakes you, and extra distance would help more than any change of mattress. It also suits you if children or pets join you most nights, 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 the stairs and landing are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Relyon Sampford Natural 1000 UK super king big enough for two adults and a child?
For occasional visits, yes. The UK super king measures 180 x 200cm and gives two adults 90cm each, so a small child tucked in the middle still leaves both of you room to lie flat. Nightly co-sleeping with an older child is more of a squeeze, but no mainstream UK size offers more width.
Relyon Sampford Natural 1000 super king or king: which should I choose?
The UK super king is 30cm wider than the UK king and the same length, which works out at 15cm more each for two sharing. Choose the UK super king if disturbance is your main problem and you have at least 3m x 2.9m. The UK king needs at least 2.7m x 2.9m.
Will a restless partner still disturb me on the Relyon Sampford Natural 1000 super king?
Less than on a smaller bed. Each of the 1,000 springs sits in its own pocket and compresses separately, so movement spreads less across the surface. In a UK super king you also each have 90cm, so a partner who turns over repeatedly is further away from you to begin with.
Does a UK super king mattress fit in a loft conversion bedroom?
It can, although sloping ceilings often decide which wall the bed goes against. We suggest at least 3m x 2.9m of usable floor for a UK super king, measured where you can stand and walk around it, with around 3.5m x 3.2m feeling comfortable. Check headroom on the side you'll get in and out.
What should I check before ordering the Relyon Sampford Natural 1000 in a super king?
Measure the route. A 6ft x 6ft 6in mattress has to clear the front door, tight landing turns and the bedroom door as it swings open. Budget for bedding too, as a UK super king takes super king sheets and a 260 x 220cm duvet. Compare the retailers listed on this page, as prices update when they change.
