Layer Details
Pocket Springs
The first layer contains individually moving springs, each nested in its own fabric pocket, which means every spring compresses on its own rather than pulling its neighbours with it. You feel this as support that follows the shape of your body and less disturbance from a partner's movement.
Pocket Springs
A second layer of pocket springs sits as part of the twin-layer design, adding a further level of independent response. The retailer's listing gives a total of 2400 springs across the mattress but doesn't specify how they're split between the two layers.

Key benefits
- Fits the typical UK bedroom: At 135 x 190cm it sits comfortably in rooms of at least 2.6m x 2.8m, which we suggest as a working minimum.
- Room for bedside tables on both sides: In an average sized double bedroom this width usually leaves space for a table each, something a UK king often squeezes out.
- Independent support for two: With 2400 springs each moving in its own pocket, you and your partner get separate contouring across a shared 135cm width.
- 67.5cm of space each: Two people sharing get 67.5cm each, enough for most couples, although restless or broader sleepers may feel the limit.
- Easiest size to dress: Standard double sheets and a 200 x 200cm duvet fit, stocked everywhere at every price point.
This size suits you if...
You share the bed most nights and your room suits the classic couples' size, you're kitting out a guest room where visiting couples will stay, or you sleep alone and want space to spread out without the bed swallowing the room. It also makes sense if your bedroom can take 2.6m x 2.8m or more but a UK king would leave you shuffling sideways past the footboard.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a light sleeper who feels every edge of that 67.5cm each. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Relyon Hand Crafted Sublime double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the twin-layer pocket springs respond to each of you independently, so a partner turning over is less likely to wake you. Broader or restless sleepers may want more width, in which case the UK king gives 75cm each.
What room size do I need for the Relyon Sublime in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, a bedside table each. This is our own guidance rather than Relyon's, so measure your room including alcoves and door swing before ordering.
Should I get the Relyon Hand Crafted Sublime in a double or a king?
It comes down to your room and how you sleep. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits rooms where a king would dominate. If your bedroom can take at least 2.7m x 2.9m and you both value space, the UK king's extra 7.5cm each is a real comfort gain.
Will a double mattress fit up the stairs in an older house?
A 135 x 190cm pocket sprung mattress won't roll or fold, so it goes up as a solid unit. Most staircases cope, but tight turns in older terraces and narrow new build landings can be awkward. Measure the tightest point of the route, including any half landing, before delivery day.
What bedding do I need for this mattress in a double?
Standard UK double sheets fit the 135 x 190cm footprint, paired with a 200 x 200cm double duvet. Because the double is Britain's most common size, bedding is stocked everywhere at every price, which is a small but genuine saving compared with kitting out a UK super king.
