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.

- Fits the typical UK bedroom: At 135 x 190cm it leaves space for wardrobes and drawers where a UK king would crowd the walls, provided your room meets our suggested 2.6m x 2.8m minimum.
- Contouring that works at close quarters: With 67.5cm each for two people sharing, the thousands of mini springs respond to each of you individually, so one partner shifting doesn't drag the other out of position.
- Cooler sharing: Two bodies raise the temperature under any duvet, and the breathable wool, cotton, hemp and flax layers shed that heat better than synthetic fillings would.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, at every price point, which matters when you're kitting out a bedroom from scratch.
- Room for tables both sides: In a room around the comfortable 3m x 3m norm, a UK double usually leaves space for bedside tables on both sides, something a wider size can rule out.
This size suits you if...
You're a couple in a typical UK bedroom and want the traditional shared size, or you're buying for a guest room that hosts visiting couples, or you sleep alone and like room to stretch out. The soft to medium feel suits lighter bodies and side sleepers particularly well, so a couple matching that description gets the best of both the size and the tension.
Consider another size if...
You and your partner both like to spread out, or one of you is a restless sleeper, and your room measures at least 2.7m x 2.9m. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

What are the dimensions of the Harrison Spinks Gold 9500 in a UK double?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. The mattress itself is 29cm deep in every size, so check that against any fitted sheets you already own. It's the middle of the five sizes this mattress comes in.
Is the Gold 9500 UK double comfortable for two adults sharing?
You get 67.5cm each for two people sharing, the long standing UK standard for couples. The mini spring layers help here: each sleeper is supported at their own points of contact, so the softer surface cradles you both separately rather than rolling you together in the middle.
What room size do I need for the Gold 9500 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance, not the manufacturer's. At the comfortable size you should still fit bedside tables on both sides plus a wardrobe, which is where the UK double beats larger sizes in an ordinary room.
Is the UK double a sensible size for one person?
Yes, and it's a common choice. The UK double is 45cm wider than the UK single, so a solo sleeper gets generous room to stretch, or to share with a dog or cat that claims a corner. The soft to medium tension suits lighter solo sleepers especially well.
Would sizing up to the UK king suit us better than the double?
If your room allows it, possibly. The UK double is 15cm narrower than the UK king and 10cm shorter, and we suggest at least 2.7m x 2.9m for the UK king. Taller sleepers gain the most from the extra length. In a smaller room, the UK double keeps the space usable.
