Layer Details
Belgian Damask Viscose Sleep Surface
A silky soft viscose cover woven from Belgian damask, which means the surface feels smooth against skin. It's highly breathable too, helping keep the sleeping environment fresher through the night.
Pashmina and Wool Layer
Pashmina fibres blended with wool give the mattress a springier, more comfortable feel. Both fibres absorb moisture and regulate temperature naturally, a real benefit if you tend to sleep warm.
Pocket Springs
2350 pocket springs, each in its own fabric pocket, move independently so the mattress responds to your shape and limits motion transfer. Rows of firmer springs along each side add edge support.

Key benefits
- More room each: At 75cm per sleeper, the UK king gives each of you 7.5cm more than a UK double, which means far less quiet negotiation over the middle of the bed.
- Length for taller partners: The 200cm length adds 10cm over a UK double, so a tall sleeper's feet stay on the mattress rather than resting at, or over, the end.
- Calmer early starts: Each spring sits in its own fabric pocket, so when one of you gets up hours before the other, the movement is much less likely to travel across.
- Edges you can use: Firmer springs along both sides mean the outer part of each 75cm half still feels supportive, so neither of you drifts towards the centre.
- A realistic room footprint: We suggest at least 2.7m x 2.9m for the UK king, a slightly smaller footprint 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 keep waking each other on a UK double, one of you is tall enough to feel the end of a 190cm mattress, or you work different hours and want your partner's comings and goings kept on their side.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m, or you already know 75cm each won't be enough. We'd recommend the UK double for smaller rooms (allow 2.6m x 2.8m), or the UK super king for more space.

FAQ's
Is the Relyon Warwick 2350 UK king long enough for someone over six foot?
At 200cm, or 6ft 6in, the UK king is 10cm longer than the UK double, which is often the main reason tall sleepers size up. If length is your only concern, the UK super king is the same length, so going bigger than the UK king adds width rather than legroom.
Will a Relyon Warwick 2350 UK king stop my partner waking me?
It should help. The independent pocket springs limit how far movement travels in every size, but the UK king adds distance too: 75cm each against 67.5cm on a UK double. That extra 7.5cm per person puts a little more space between a restless sleeper and a light one.
Relyon Warwick 2350 UK king or super king for a couple?
The UK super king gives 90cm each, 15cm more per person than the UK king, but we suggest at least 3m x 2.9m for it against 2.7m x 2.9m for the UK king. If floor space is tight, the UK king is the more realistic choice; if the room allows, the UK super king gives more breathing room.
Will a Relyon Warwick 2350 king fit a new build master bedroom?
Allow at least 2.7m x 2.9m, and measure once fitted wardrobes and bedside tables are accounted for, because new build master bedrooms often lose more usable floor than the plans suggest. We'd call 3.2m x 3.2m comfortable. If you fall short, the UK double needs at least 2.6m x 2.8m.
Is 75cm each enough on a king mattress for two adults?
For most couples, 75cm each is a comfortable step up from a UK double, and the firmer side springs on the Warwick 2350 let you sleep nearer the edge. If a dog regularly joins you or either of you sprawls, the UK super king's 90cm each may suit you better.
