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
- More room each: At 75cm per person, the UK king gives each of you 7.5cm more than a UK double, which means fewer nights nudged towards the edge.
- Quieter early starts: Each spring sits in its own pocket and moves on its own, so a partner leaving hours before you sends less movement across to your side.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over a UK double, which gives a taller partner space for their feet at the end.
- Manageable in a typical main bedroom: We suggest a room of at least 2.7m x 2.9m, a little less demanding than the 3m x 2.9m we suggest for the UK super king.
This size suits you if...
You share the bed every night and have started to feel crowded on a UK double. It also suits you if one of you rises much earlier or stands noticeably taller, and you want 10cm more length without the room demands of a UK super king.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m. We'd recommend the UK double instead, and we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Is the Relyon Sampford Natural 1000 UK king big enough for two adults?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than a UK double. If you both sprawl, or a dog regularly joins you, the UK super king offers 90cm each, so the UK king gives 15cm less per person than the UK super king.
Will a tall person fit on the Sampford Natural 1000 in UK king size?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. That extra length is often the real reason taller sleepers upgrade. Moving up to the UK super king won't add any more length, because the UK super king and the UK king are the same length.
Does a king size Sampford Natural 1000 help with partner disturbance?
It helps in two ways. The 1,000 pocketed springs compress independently, which limits how far movement travels. The UK king also puts 75cm between you rather than the UK double's 67.5cm each. If one of you works early shifts, that combination means a little less jolting when the other gets up.
Relyon Sampford Natural 1000 UK king or UK super king: which should I choose?
Choose the UK king if your room is at least 2.7m x 2.9m but short of the 3m x 2.9m we suggest for the UK super king. The UK super king gives 15cm more each across its width, with no extra length. For most couples, the UK king is the easier fit.
Will the Sampford Natural 1000 UK king fit in a new build master bedroom?
Often, but measure first. New build main bedrooms can feel smaller once fitted wardrobes and bedside tables go in. We suggest at least 2.7m x 2.9m for a UK king, measured after furniture is placed. If you come up short, the UK double needs at least 2.6m x 2.8m.
