Layer Details
Pocket springs
1000 Cortec Quad Revolution springs sit in cloth pockets and are grouped in fours, with mini springs inside the regular springs. This is the main support layer, so it is what gives the mattress its firm, held-up feel.
Mini pocket springs
A layer of 1000 Posturfil springs, plus an extra 7500 mini springs, sits above the main springs for contouring. It adds some shape-following give on top of the firm support below.
Wool, hemp and flax blend layer
Layers of wool, hemp and flax are blended to improve breathability. Air can move through the mattress more easily, which helps if you tend to feel the heat at night.
Cotton, hemp and flax layer
An extra layer of cotton, hemp and flax wicks moisture away. That should help the surface feel drier and fresher while you sleep.
Wool comfort layer
The top layer is 100% traceable British wool, which gives a plush surface. It softens the feel at the top, though the mattress overall is still firm.

Key benefits
- Real space for one: At 30cm wider than the UK single, it gives a solo back or front sleeper on this firm surface plenty of room to change position.
- Fits rooms a double crowds: It's 15cm narrower than the UK double, which can be the difference between a usable box room and one where the door barely clears.
- Pocket springs across the full width: The springs move independently, so if a partner joins you for the occasional night, their movement is less likely to travel across to your side.
- Standard 4ft bedding and frames: The UK small double is a stocked UK size, so fitted sheets and bed frames are easy to find rather than a special order.
- Sensible guest room choice: Firm support suits a bed that hosts different people, and the footprint leaves space for a wardrobe or desk in a second bedroom.
This size suits you if...
You sleep alone, prefer a firm supportive feel, and have outgrown a single without having the floor space for a full double. It also fits if you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or a loft conversion or downsized bedroom where every centimetre of width matters. Allow at least 2.4m x 2.8m of floor space.
Consider another size if...
You share the bed every night, as 120cm is a squeeze 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 for it.

FAQ's
Is the small double Gold 9500 big enough for a couple?
For occasional nights, yes. The pocket springs respond individually, so two people sharing the 120cm width won't roll into each other the way they might on an open-coil bed. For every night, it's tight, and the firm feel gives you less give to soften the squeeze. Couples sharing nightly should look at the UK double or UK king.
What room size do I need for the Gold 9500 small double?
We suggest allowing at least 2.4m x 2.8m of floor space. That's our own guidance rather than the manufacturer's, and it leaves enough clearance to walk round the bed and open drawers. If your room is smaller than that, measure carefully before ordering, because a firm pocket spring mattress this substantial is awkward to return once it's up the stairs.
Should I choose the small double or the UK double?
It usually comes down to the room. The UK small double is 15cm narrower than the UK double and the same length, so it suits box rooms, studios and loft conversions where a 4ft 6in frame would dominate. If you have at least 2.6m x 2.8m and a partner stays regularly, the UK double is the safer pick.
How much bigger is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 6ft 3in. For a teenager or adult who has outgrown a single, that extra width is noticeable every night, while the unchanged length means the bed often fits along the same wall the single occupied.
