Layer Details
- Cover. A Belgian Damask viscose sleep surface, which means a silky soft feel against bedding. It is highly breathable, helping to create a fresher sleeping environment.
- Comfort Fillings. A naturally soft, lightweight blend of British wool and silk. These fibres offer excellent insulation, which means they help keep you cool in summer and warm in winter.
- Support System. 1,500 pocket springs, each mounted in its own separate fabric pocket. Because the springs work completely independently, they follow your body shape more closely and relieve pressure where you need it.

- 90cm each for two sharing: Each of you gets 90cm of width, which means turning over, spreading out or starfishing without ever touching in the night.
- Pocket springs across the full width: The 1,500 springs move independently, so a restless partner's tossing stays on their side rather than travelling across 180cm of mattress to wake you.
- Space for night-time visitors: When a child pads in at 3am, or the dog treats the bed as routine, a super king absorbs the extra body without anyone perching on the edge.
- Wool and silk over a big surface: Natural fillings breathe well, which matters more at this size, where two adults and occasional company generate plenty of warmth between them.
- The right scale for a large master: In a period property or a generous new build master bedroom, a UK king can look a little lost; the super king fills the room properly.
This size suits you if...
You share the bed every night and want the most distance a standard UK size can give you, your partner is genuinely restless and space matters more to you than any comfort layer, or children and pets regularly join you and you need everyone to keep a fair share. Your room should comfortably clear our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest for a super king, or you sleep alone. The UK king of this mattress would suit you better: it is the same length, and we suggest at least 2.7m x 2.9m for it.

Is the Relyon Lambrook 1500 super king big enough for co-sleeping with children?
It is the best-placed size in the range for it. With 90cm each for two people sharing, there is slack for a small visitor without either adult ending up on the edge, and the 1,500 pocket springs keep a wriggling child's movement fairly localised. It is a compromise on space, but a workable one at this width.
Will a super king Lambrook 1500 stop me feeling my partner move?
Two things help. Each pocket spring sits in its own fabric pocket and compresses independently, so movement transfers less than on an open coil bed. More simply, at 180cm wide your partner is further away, and distance does more for undisturbed sleep than any construction detail. For a truly restless sharer, this size is the strongest choice.
What room size do I need for the super king Relyon Lambrook?
We suggest at least 3m x 2.9m, which is our own guidance rather than Relyon's. That allows walking space on both sides and room for bedside tables. In a loft conversion, check the ceiling slope too: at 180cm wide, the bed may only fit against one wall, so measure before you commit.
How much wider is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. Shared between a couple, the UK king gives 75cm each while the UK super king gives 90cm each, so you gain 15cm more each. That extra margin is what makes a fidgety partner easy to ignore.
Is the Lambrook 1500 super king hard to get upstairs?
It can be. This is a traditional pocket spring mattress, not a rolled foam one, so it arrives at its full 180 x 200cm and won't bend far. Measure your stairwell, landing turns and door swing before ordering. If access is tight, sizing down to the UK king, which is 30cm narrower, may be the practical answer.
