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.

Key benefits
- The classic shared size: At 135 x 190cm, the UK double gives 67.5cm each for two people sharing, enough for most couples who sleep close.
- Fits typical UK bedrooms: We suggest allowing at least 2.6m x 2.8m, which leaves space for bedside tables on both sides in the average British room.
- Wool and fibre fillings for two: British wool, hemp and flax breathe better than foam, which matters more when two bodies are warming the same mattress.
- 9,500 springs across the width: Three tiers of pocketed springs respond to each sleeper individually, so a heavier partner shouldn't pull you into their side of the bed.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit this size, and both are stocked everywhere at every price.
This size suits you if...
You're a couple and the UK double is the size you've always shared, or your bedroom sits around our suggested 2.6m x 2.8m minimum and a king would crowd it. It also suits a guest room that hosts visiting couples, where you want a genuinely comfortable natural-fillings bed rather than a token spare, or a solo sleeper who likes room to stretch out.
Consider another size if...
You both like space and your room can take something bigger. The UK double is 15cm narrower and 10cm shorter than the UK king, so if you can allow at least 2.7m x 2.9m, we'd recommend the UK king instead.

FAQ's
Is a UK double Gold 9500 wide enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the Gold 9500's pocketed springs respond to each of you separately, so movement transfers less than on a connected-coil bed. If one of you is broad-shouldered or a restless sleeper, the UK king adds 15cm of width and 10cm of length.
Will the Gold 9500 double fit in a small bedroom?
It fits most UK bedrooms. We suggest allowing at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That usually leaves room for bedside tables on both sides plus a wardrobe, which is exactly where the UK double earns its popularity over the roomier but hungrier UK king.
Can a Gold 9500 double be carried up narrow stairs?
This is a traditional pocket spring mattress, so it arrives full size rather than rolled in a box. At 135 x 190cm it will need turning room on landings and stairwells, which can be tight in older terraces and some new builds. Measure your access route before ordering and check the retailer's delivery guidance.
Should I get the Gold 9500 in a double or a small double?
The UK double is 15cm wider than the UK small double, and both are the same length. For a couple, that extra width is usually worth having. The UK small double makes sense for a solo sleeper in a compact room; we suggest at least 2.4m x 2.8m for it, against 2.6m x 2.8m for the UK double.
Where can I buy the Gold 9500 double at the best price?
Prices change often, so the sensible move is to compare the retailers listed on this page, where prices are updated as retailers change them. The double sits in the middle of the five sizes this mattress comes in, and it's a serious spend, though the spring count and natural fillings go some way to explaining it.
