Layer Details
- Belgian Damask Viscose Sleep Surface. A silky, breathable cover that helps keep the sleep surface feeling fresh. It's the first thing you'll feel, and it's noticeably softer than the firm rating might suggest.
- Sustainably Sourced Somerset Wool. Wool is naturally breathable and gently cushioning, which means it helps regulate your temperature through the night. It also gives the firm build a touch of resilient comfort at the surface.
- Soft White Fibres. These fibres are made from 100% polyester, chosen for recovery and durability. In practice, that means the comfort layers should hold their shape rather than flattening quickly.
- Cotton. A natural filling that helps regulate body temperature and adds a layer of support. Combined with the wool above it, this keeps the mattress breathable throughout.
- 2500 Pocket Springs. Each spring sits in its own fabric pocket and works independently, which means better pressure relief and less motion transfer than an open coil unit. Additional mini pocket springs provide closer, more responsive support.

- 90cm each for two sleepers: Each of you gets 90cm of width, which means a restless partner's turning happens further away and is much less likely to wake you.
- Firmness that holds up with extra bodies: The firm pocket sprung build keeps its shape when a child or dog joins you, so nobody sinks towards the middle of the UK super king.
- Independent springs across a wide surface: Each of the 2500 pocket springs moves on its own, so movement on one side travels less across the bed than it would on an open coil unit.
- Cooler sleeping with more people in the bed: Somerset wool and cotton fillings are breathable, which matters when a crowded bed would otherwise trap heat through the night.
- Proportioned for a large bedroom: In a period property or a generous master bedroom, the UK super king fills the space properly where a UK king can look a little lost.
This size suits you if...
You share the bed with someone who tosses and turns and you want real distance between you, or your children and dogs regularly end up joining you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is tighter than 3m x 2.9m, or you rarely share the bed with anyone else. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Relyon Wallbridge Ortho 2500 super king big enough for two adults and a child?
For occasional night visits, yes. The UK super king gives 90cm each for two adults sharing, so a small child who climbs in has somewhere to go without anyone ending up on the edge. The firm pocket springs also stop the middle dipping under the extra weight, although nightly co-sleeping as a family of four will still feel full.
Relyon Wallbridge Ortho 2500 super king vs king: how much extra space do you get?
The UK super king is 30cm wider than the UK king, and both are the same length. That works out at 15cm more each for two people sharing. If your room is on the small side, the UK king needs at least 2.7m x 2.9m, while we suggest at least 3m x 2.9m for the UK super king.
How much bigger is the Wallbridge Ortho 2500 super king than a double?
Quite a lot. The UK super king is 45cm wider and 10cm longer than the UK double, and gives 22.5cm more each for two sharing. For couples moving up from a UK double, the difference in how often you disturb each other is usually the thing they notice first.
Is a firm super king mattress a good idea if my partner is a restless sleeper?
It helps on two counts. The width gives each of you 90cm, and distance does more to stop disturbance than any comfort layer can. The pocket springs also work independently, so a partner turning over sends less movement your way. Lightweight side sleepers may still find the firm feel a little unforgiving at the shoulders.
Will a Relyon Wallbridge Ortho 2500 super king suit a loft conversion bedroom?
Only if the full-height floor area is generous. We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable, and in a loft conversion the sloping ceiling usually decides which wall the bed can go against. Measure where you can stand upright on both sides, and check the door can still open fully.
