Layer Details
Cover
Harrison Spinks' own woven cover meets fire safety standards without FR chemicals. That means fewer treatments between you and the fillings.
Wool comfort layer
A layer of 100% traceable British wool sits near the surface, which means natural insulation and breathability where you'll feel it most.
Blended fillings
Blended wool, hemp and flax boost airflow through the mattress. In practice, this helps keep you at a comfortable temperature overnight.
Moisture-wicking layer
A further layer of cotton, hemp and flax wicks moisture away, which reduces heat build-up while you sleep.
Durability layer
Ecotex fibres add durability, helping the fillings hold their shape over time.
Posturfil mini springs
1,000 Posturfil springs react instantly to movement. You'll feel this as flexible comfort that adjusts as you shift position.
Mini springs
An additional 7,500 mini springs create more points of contact with your body, contouring closely to your shape for a more personalised feel.
Cortec Quad Revolution springs
The base layer holds 1,000 Cortec Quad Revolution springs, with mini springs nested inside regular ones, individually pocketed and grouped in fours. This delivers adaptive, responsive support beneath the comfort layers.

- Real space for one sleeper: At 30cm wider than the UK single, this small double gives a lone adult room to stretch, roll and change position without feeling hemmed in.
- Fits rooms a double crowds: It's 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Modest room requirement: We suggest a minimum of 2.4m x 2.8m, so box rooms, loft conversions and small second bedrooms can still take a bed built for adults.
- Natural fillings, no compromise on size: The traceable British wool, hemp and flax layers are identical in the small double, so downsizing the footprint doesn't mean downgrading the mattress.
- Cooler nights in a snug room: Smaller rooms can run warm, and the breathable, moisture-wicking fibres help this mattress stay comfortable where a foam-topped bed might not.
- Handles the occasional shared night: A guest room in this size copes with visiting couples for a weekend, while a solo regular sleeper gets the everyday benefit.
This size suits you if...
You sleep alone and have outgrown a single, perhaps a teenager or an adult in a room that can't spare the floor space a double demands. Or your bedroom, loft conversion or studio is tight enough that 15cm of width decides whether you can still walk round the bed. It also suits a guest room used by couples occasionally rather than nightly.
Consider another size if...
You share the bed every night and want it to feel comfortable long term. The UK small double is 15cm narrower than the UK double, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

Is a small double Gold 9500 big enough for a couple?
For occasional nights, yes. At 120 x 190cm the UK small double will take two adults for a weekend stay, which makes it a sensible guest room choice. For a couple sharing every night it's a squeeze, and the UK double, 15cm wider, would suit far better. Solo sleepers get the best of this size.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double, which leaves enough space to walk round the bed and open drawers or wardrobe doors. That's our own guidance rather than the manufacturer's. If your room is smaller than this, measure carefully before ordering, as the Gold 9500 is a substantial mattress to manoeuvre.
How much bigger is the small double than the single Gold 9500?
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 point of this size: a solo sleeper gets noticeably more room to spread out without the footprint of a full double. The construction and feel are identical across both sizes.
Is the small double worth it over the double for one person?
If you sleep alone, often yes. The UK small double is 15cm narrower than the UK double, which frees up floor space in a compact room, and we suggest a minimum of 2.4m x 2.8m rather than the 2.6m x 2.8m we'd allow for the UK double. You still get generous width for one adult.
Where can I buy the Gold 9500 in a small double?
Availability shifts, so the most reliable answer is the live price table on this page, which updates as retailers change their listings and prices. The small double is a standard UK 4ft size, so frames and fitted sheets are easy to find; most people pair it with a standard double duvet.
