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
- Real space for one: At 30cm wider than the UK single, a solo sleeper gets genuine room to spread out without the footprint of a full double.
- Fits rooms a double overwhelms: It's 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- 2400 springs at any width: The twin-layer pocket spring construction is the same in every size, so you get the full 2400 individually pocketed springs in this compact format.
- Luxury feel for occasional sharers: Couples staying the odd night in a guest room or holiday let get independent spring response and low motion transfer, rather than a budget compromise.
- Standard 4ft sizing: The UK small double is a standard British size, so frames, small double fitted sheets and a regular double duvet are all easy to find.
This size suits you if...
You sleep alone most nights, have outgrown a single and want a mattress you can spread out on without sacrificing the floor space of a compact bedroom. It also suits a well-appointed guest room or holiday let where couples share occasionally rather than nightly, and where you want the bed to feel genuinely comfortable rather than merely adequate. Allow a room of at least 2.4m x 2.8m.
Consider another size if...
You share the bed every night, in which case 120cm across two people feels tight at this price. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Is a UK small double Relyon Sublime big enough for a couple?
For occasional nights, yes. The pocket springs respond to each sleeper independently, so a visiting couple won't disturb each other much. For every night, 120cm across two adults is a squeeze, and at this level of investment we'd point regular sharers to the UK double, which gives 67.5cm each.
What size room do I need for a small double Relyon Sublime?
We suggest a room of at least 2.4m x 2.8m. That allows you to walk round the bed and open drawers without shuffling sideways. If your room is smaller than that, the UK single is 30cm narrower at the same length, and we suggest at least 2.1m x 2.8m for it.
How big is the Relyon Hand Crafted Sublime in a UK small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in in imperial. That's the standard UK small double footprint, so any 4ft bed frame or divan base should fit it, and small double fitted sheets are widely available on the high street.
Does the UK small double have fewer springs than the bigger sizes?
The retailer's listing gives 2400 springs for the mattress, split across two layers of individually pocketed springs, and doesn't publish a different count per size. What you can be sure of is the construction itself: twin-layer pocket springs that compress independently, which is what gives the contouring feel.
Should I get the small double or the double Relyon Sublime?
Sleeping alone in a compact room, the UK small double gives you generous space for one. Sharing regularly, take the UK double: it's 15cm wider, the same length, and gives 67.5cm each for two people. The deciding factor is usually the room, since the UK double needs at least 2.6m x 2.8m by our guidance.
