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.

Key benefits
- 90cm of width each: Two sharers get 90cm each, so you can stretch out or turn over without negotiating for space through the night.
- Distance plus isolation: The 1,000 pocket springs already limit motion transfer, and at this width there's simply more mattress between you and a fidgeting partner.
- Space for the whole household: If children wander in during the night or a dog claims the foot of the bed, the extra 30cm over a UK king absorbs it.
- Breathable natural fibres across a big surface: Wool and silk regulate temperature, which matters more when two adults, and sometimes more, share one sleep surface.
- Fills a large master properly: In a period property or generous new build master, a smaller mattress can look lost; the 6ft x 6ft 6in footprint sits in proportion.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and distance matters as much as spring quality, or children and pets regularly join you and everyone still needs their share. Your room should measure at least 3m x 2.9m for this size to work comfortably.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or the bed would dominate the space. The UK king would suit you better: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
Is the Relyon Guildford 1000 super king good for couples with children who join them at night?
It's one of the better setups for it. The UK super king measures 180 x 200cm, so a small visitor at 3am doesn't push either adult to the edge. The pocket springs respond to each body individually too, which means a wriggling child disturbs the rest of the bed less than a traditional sprung unit would.
Will the Relyon Guildford 1000 super king help if my partner is a restless sleeper?
More than any comfort layer would, in our view. With 90cm each for two people sharing, you're simply further from the movement, and each of the 1,000 pocket springs compresses independently rather than rocking the whole mattress. That's 15cm more space each than the UK king offers, which is a noticeable difference when someone turns constantly.
What room size do I need for the Relyon Guildford 1000 in a super king?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels right, giving space to walk round the bed and open wardrobe doors. That guidance is ours rather than Relyon's. Measure door swing and any landing turns before ordering too, as a 180 x 200cm mattress is awkward on tight staircases.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king; both are 200cm long. For two people sharing, that works out at 90cm each rather than the UK king's 75cm, so 15cm more space per person. If your room can hold it, that extra width is what makes a restless partner or visiting children manageable.
Where can I buy the Relyon Guildford 1000 in a UK super king?
Compare the retailers listed on this page: the prices shown are updated as retailers change them, so what you see here reflects current stock rather than a snapshot. Availability in the UK super king can differ from the smaller sizes, so it's worth checking the live table rather than assuming every stockist carries this one.
