Layer Details
- Cover. A knitted fabric cover, which means a soft-touch surface against your skin from the moment you lie down.
- Advanced e-Fibre®. An award-winning comfort layer designed for luxury comfort and breathability, so air moves through rather than building up heat.
- Memory e-Fibre®. A memory layer offering quick-response pressure relief. Unlike traditional memory foam, it recovers quickly, so you won't feel stuck when you change position.
- Rebound e-Fibre®. A rebound layer that contours to your shape, which means support that follows your body rather than a flat, rigid feel.
- e-Spring™ core. A deep sprung core with supportive comfort layers, giving the mattress its firm, stable foundation.

- Real space for one: The UK small double is 30cm wider than the UK single, which means a solo sleeper can stretch, roll and starfish without meeting the edge.
- Fits where a UK double will not: At 15cm narrower than the UK double, this size can be the difference between a bedroom door that clears the frame and one that doesn't.
- Firm support at any width: The e-Spring™ core gives the same firm, stable feel here as in larger sizes, which suits back and front sleepers who dislike sinking.
- Cooler sharing on occasional nights: The breathable e-Fibre® layers let air move through, so two people sharing this compact size for a guest stay shouldn't overheat.
- Standard 4ft bedding: Small double is a standard UK size, so fitted sheets and frames are easy to find, and a standard double duvet works on top.
This size suits you if...
You're a solo adult who has outgrown a single and wants proper spreading room, your bedroom, box room or loft conversion can't take a standard double without losing walking space, or you're kitting out a guest room where couples stay occasionally rather than every night. The firm feel also needs to suit you: it favours back and front sleepers over lightweight side sleepers.
Consider another size if...
You share the bed every night, in which case 120cm across gets tight for two adults long term. We'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m of room for it.

Is a small double big enough for two on the Jay-Be Benchmark S3?
For occasional nights, yes. Two adults can share the UK small double comfortably enough for a guest stay, and the firm e-Spring™ core keeps the surface stable when one person moves. For every night, the UK double is the sensible step up: it's 15cm wider, the same length, and shares less shoulder room per person is less of a compromise.
Will the Jay-Be Benchmark S3 small double fit in a box room?
Often, yes. The mattress is 120 x 190cm, and we suggest a room of at least 2.4m x 2.8m so you can still open drawers and walk round the bed. Measure with the door swing in mind: in box rooms and studios, that 15cm saved against a UK double is frequently what lets the door clear.
How much wider is the small double than the single in this mattress?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is aimed at one sleeper rather than two: a teenager who has outgrown a single, say, in a room that can't spare the floor space a UK double would take.
What bedding do I need for this size?
Small double, or 4ft, fitted sheets to match the 120 x 190cm mattress, with a standard double duvet on top. Because 4ft is a standard UK size, sheets and frames are widely available, though the range is slimmer than for the UK double, so it's worth checking a retailer stocks the colours you want before buying the frame.
