Layer Details
- Belgian Damask Viscose Sleep Surface. A silky, breathable damask cover, which means air can move through the sleep surface more easily. That helps the bed feel a little fresher through the night.
- Silk. A light, soft silk layer sits near the top of the mattress. It adds a gentle, luxurious feel without trapping heat.
- Sustainably Sourced British Wool. Wool gives cushioning with natural resilience, which means it springs back rather than compressing flat over time. It also regulates temperature well, a plus if you run warm.
- Deep soft layer. A deeper soft layer adds extra cushioning between the natural fibres and the springs. It softens the initial feel when you lie down.
- 1000 Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your shape rather than pushing back as one unit. That gives better pressure relief and less motion transfer between partners.

- 75cm each for two sharing: Two sleepers get 75cm of width apiece, which means you can both change position without negotiating for territory.
- Less disturbance on different schedules: The pocket springs move independently, so an early riser slipping out at six leaves the other side of the bed largely undisturbed.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over the UK double, a genuine relief if one of you is approaching six foot.
- Wool comfort with room to spread out: The temperature-regulating British wool layer covers a wider surface here, so neither sleeper ends up pressed against the cooler edge.
- A medium feel that shares well: The medium firmness suits most back and side sleepers, so partners with slightly different preferences can usually both settle on it.
This size suits you if...
You share the bed every night and have started to feel cramped on a UK double, one of you is tall enough that your feet reach the end of a standard-length mattress, or you and your partner keep different hours and want the pocket-sprung build to keep movement on one side from reaching the other. Allow at least 2.7m x 2.9m of bedroom for it.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives two sharers 67.5cm each.

Is a UK king big enough for a couple with different sleep schedules?
Yes, and this build helps. With 75cm of width each and 1,000 pocket springs that compress independently, one partner getting up hours before the other causes far less ripple across the mattress than an open-coil bed would. If one of you is a light sleeper, the width matters as much as the springs: you're simply further apart.
Will the Relyon Guildford 1000 king fit a new build master bedroom?
Often, but measure first. New build masters can feel smaller than they look once fitted wardrobes go in, and we suggest at least 2.7m x 2.9m for a UK king so you can walk round both sides. If your room falls short after the wardrobes, the UK double needs at least 2.6m x 2.8m.
Is the UK king long enough for someone over six foot?
It's the sensible choice. At 200cm, the UK king is 10cm longer than the UK double, so a sleeper approaching or just over six foot gets clear space below their feet rather than pressing against the footboard. For many tall sleepers, that extra length is the real reason to size up, more than the width.
Should we choose the king or the super king in this mattress?
It comes down to room size and how much space you want. The UK super king is 30cm wider, giving 90cm each rather than the UK king's 75cm, but we suggest at least 3m x 2.9m of floor space for it. If a dog routinely joins you and takes more than its share, the UK super king is the better buy.
