Layer Details
Cover
A knitted fabric cover, which gives a soft-touch sleep surface against the skin.
Advanced e-Fibre®
An award-winning fibre comfort layer designed for luxury comfort and breathability. Because it's fibre rather than foam, it allows air to move more freely, which means less heat building up overnight.
Rebound e-Fibre®
A resilient fibre layer that provides contour support, shaping to your body while springing back into place.
Micro e-Pocket™ springs
A layer of small pocketed springs that move independently, which means the mattress adapts to your shape and weight rather than pushing back uniformly.
e-Spring™ core
The main spring core, providing the deep support that keeps your spine aligned.

Key benefits
- Real room for one: At 120cm wide, the UK small double gives a solo back or front sleeper generous space to stretch out on this firm, no-sink surface.
- Fits compact bedrooms: It's 15cm narrower than the UK double, which can be the difference between a door that clears and one that doesn't in a box room or studio.
- Cool across the width: The fibre comfort layers breathe better than foam, so even sprawled across the full 4ft you shouldn't feel heat pooling beneath you.
- Easy to furnish around: 4ft is a standard UK size, so small double frames, fitted sheets and a regular double duvet are all simple to find.
- Practical guest room choice: Firm support suits a rotating cast of guests, and the size sleeps one person well or two for the odd weekend.
This size suits you if...
You sleep alone and want more width than a UK single without giving up the floor space a double demands, perhaps a teenager who has outgrown their bed in a room that can't shrink further, or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly. A firm feel suits you, especially if you sleep on your back or front.
Consider another size if...
You share the bed every night, in which case 120cm is a squeeze at any firmness. We'd recommend the UK double instead: it's 15cm wider, the same length, and we suggest a room of at least 2.6m x 2.8m for it.

FAQ's
Is the Jay-Be Benchmark S5 UK small double big enough for a couple?
For occasional nights, yes. Two adults get 120cm between them, and the firm tension means one person moving won't tip the other into a dip. For every night, though, it's tight at the shoulders, and we'd point regular couples to the UK double or UK king pages of this mattress instead.
What are the dimensions of the Jay-Be Benchmark S5 in a small double?
The UK small double measures 120 x 190cm, or 4ft x 6ft 3in. That's 30cm wider than the UK single and the same length, so a taller sleeper gains no legroom by choosing it; the extra is all width for spreading out.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That gives you space to walk round the bed and open drawers without shuffling sideways, which matters in the box rooms and loft conversions this size is usually bought for. Measure the room before the mattress, especially around sloped ceilings and door swings.
Should I get the Jay-Be Benchmark S5 in a small double or a double?
It comes down to the room. The UK small double is 15cm narrower than the UK double at the same length, and we suggest at least 2.6m x 2.8m for the UK double. If your room clears that comfortably and two of you share regularly, size up; if it doesn't, the small double is the sensible pick.
