Layer Details
- Wool comfort layer. A plush layer of 100% traceable British wool sits at the top, which means a naturally insulating and breathable sleep surface. Wool helps regulate temperature rather than trapping heat.
- Blended natural fibres. Layers blending wool, hemp and flax improve the breathability of the mattress. In practice, that helps keep you at a comfortable temperature through the night.
- Moisture-wicking layer. An additional layer of cotton, hemp and flax wicks away moisture, which reduces heat building up around you. Useful if you tend to wake up warm.
- Ecotex durability layer. A layer of Ecotex fibres adds durability, helping the comfort layers above hold their shape over time.
- Posturfil mini springs. A layer of 1,000 Posturfil springs reacts instantly to movement, which means the surface adjusts as you shift position rather than leaving you to settle into a dip.
- Mini springs. A further 7,500 mini springs create more points of contact with your body, contouring closely to your shape. That's what gives the personalised, cradling feel.
- Cortec Quad Revolution springs. The base support comes from 1,000 of Harrison Spinks' Cortec Quad Revolution springs: mini springs placed inside regular springs, pocketed individually and secured in groups of four. This delivers adaptive, responsive support underneath the softer comfort layers.

- Room to spread out alone: At 120cm wide, this size gives one sleeper 30cm more width than a UK single, which means you can shift position freely through the night.
- Contouring across the whole surface: The Gold 9500's mini springs hold many points of contact with your body, so a solo sleeper using the full 120cm width feels cradled wherever they settle.
- Fits rooms a double would crowd: It's 15cm narrower than a UK double, which can be the difference between clear walkways and a squeezed box room or loft conversion.
- Natural fillings in a guest-friendly size: Wool, hemp, flax and cotton breathe well, so occasional guests, including couples for a night or two, stay comfortable without heat building up.
- Standard 4ft bedding and frames: The UK small double is a stocked UK size, so fitted sheets and frames are easy to find, and a standard double duvet drapes generously over it.
This size suits you if...
You sleep alone, you've outgrown a UK single and you want genuine stretching room without giving your bedroom over to the bed. Or you're furnishing a compact second bedroom, a loft conversion or a holiday let where a full double frame would block walkways, and the bed will host couples occasionally rather than nightly. The soft to medium feel suits you best if you're a side sleeper or a lighter body.
Consider another size if...
You share the bed every night and can spare another 15cm of floor width. At 120cm, two adults on a soft to medium surface will feel each other's movement; we'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room.

Is a small double big enough for the Harrison Spinks Gold 9500 to work properly?
Yes. The spring construction is the same in every size, so a solo sleeper on the UK small double gets the full contouring effect across 120cm of width. The size question is about people, not performance: one adult has generous room, while two adults every night would be better served by a wider size.
What room size do I need for a small double Gold 9500?
We suggest allowing at least 2.4m x 2.8m. That leaves space to walk around the bed and open the door comfortably. In a box room, studio or loft conversion, measure before you buy: the 15cm saved against a UK double is often what keeps a wardrobe usable or a doorway clear.
Can a couple share the Gold 9500 in a UK small double?
For occasional nights, yes, which makes it a sensible guest room pick. The breathable wool and cotton layers help two people avoid overheating. For every night, 120cm is tight for two adults, especially on a soft to medium surface where you settle into the mattress, and the UK double gives each person noticeably more room.
How does the small double compare to the single for 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 the whole argument: a teenager who has outgrown a single, or an adult who likes to spread out, gets real freedom to move while the room only needs around 2.4m x 2.8m.
What bedding fits the Gold 9500 in a small double?
You'll need small double, 4ft, fitted sheets to get a proper fit over the 29cm depth. For the top layer, a standard double duvet works well and drapes generously over the 120cm width. Because 4ft is a standard UK size, both are easy to find on the high street and online.
