Layer Details
Cover
A knitted fabric cover, which means a soft touch surface against your sheets.
Advanced e-Fibre®
Jay-Be's award-winning Advanced e-Fibre® sits just below the cover for luxury comfort. It's also breathable, so heat can escape rather than build up around you.
Memory e-Fibre®
A fibre alternative to memory foam, giving quick response pressure relief. You get cushioning at the shoulders and hips without the slow sink of traditional foam.
Rebound e-Fibre®
Rebound e-Fibre® provides contour support, which means it follows your shape while pushing back enough to keep you from bottoming out.
Micro e-Pocket™ springs
A layer of small pocket springs that move independently for adaptable support. They respond to each part of your body separately, useful if you and a partner are different weights.
e-Spring™ core
The e-Spring™ core forms the base of the mattress, providing the main structural support beneath the comfort layers.

Key benefits
- Real room to stretch out alone: At 120cm wide, the UK small double is 30cm wider than the UK single, so a solo sleeper on this soft mattress can shift position freely all night.
- Soft feel suits how you'll use it: A soft, contouring mattress and a size aimed mostly at one sleeper go well together, since lighter solo sleepers are exactly who this feel supports best.
- Fits rooms a double would crowd: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Fibre layers breathe in a smaller room: Jay-Be's e-Fibre® comfort layers let heat escape rather than trap it, useful in box rooms and loft spaces where air tends to sit still.
- Standard 4ft size, easy to dress: Small double is a standard UK size, so frames and fitted sheets are straightforward to find, with a normal double duvet on top.
This size suits you if...
You sleep alone, you've outgrown a UK single, and your room can't spare the width a UK double demands. Or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, and a soft, breathable mattress will keep lighter guests comfortable. It also suits a teenager moving up from a single without giving away too much floor space.
Consider another size if...
You share the bed every night, because 120cm is snug for two adults full time, and a soft mattress amplifies any partner movement. If your room allows it, we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

FAQ's
Is a small double big enough for a couple on the Jay-Be Benchmark S7?
For occasional nights, yes. Two adults can share 120cm of width for a weekend stay, and the Micro e-Pocket™ springs adjust to each sleeper separately. For every night, it's a squeeze on a soft mattress, where you naturally settle towards each other. Couples sharing nightly would be better served by the UK double.
What room size do I need for the Jay-Be S7 in a UK small double?
We suggest at least 2.4m x 2.8m. That leaves enough clearance to walk round the bed and open the door comfortably. It's our own guidance rather than Jay-Be's, and it's the reason this size works in box rooms, loft conversions and small second bedrooms where a UK double would leave no walking space.
How much wider is the small double than the single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width matters more on a soft mattress like the S7, where you sink in slightly and appreciate room to change position. It's a natural step up for a teenager or an adult who spreads out.
What bedding fits the Jay-Be S7 small double?
You'll need small double (4ft) fitted sheets, which are widely stocked because 4ft is a standard UK size. A standard double duvet works fine on top, with a little pleasant overhang on each side. The mattress is 21cm deep, on the slimmer side, so most standard-depth fitted sheets will tuck in without strain.
Where can I buy the Jay-Be Benchmark S7 in a small double?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's worth checking back before you buy. Availability varies by size, and the small double isn't always stocked as widely as the UK double or UK king, so the live table is your best guide.
