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.

- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who fidgets on this gentler, contouring surface is simply further away.
- Movement stays local: The 7,500 mini springs respond point by point, so across a 180cm width one sleeper's shifting barely reaches the other side.
- Room for wandering children: When a small visitor climbs in at 3am, the full 6ft of width means everyone keeps a usable share of the bed.
- Natural fillings across a wide surface: Wool, hemp, flax and cotton breathe well, which matters more when three bodies, or two people and a large dog, share one mattress.
- Softness suits sprawlers: The soft to medium feel lets shoulders and hips settle in, and the extra width means side sleepers can spread out without meeting in the middle.
This size suits you if...
You share the bed every night and a UK king has started to feel crowded, you have a partner who moves constantly and you want distance as well as cushioning, or children and pets treat your bed as communal territory. It also suits couples with a large master or period bedroom where a smaller mattress would look and feel undersized.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for this size, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs a room of at least 2.7m x 2.9m.

How big is the Harrison Spinks Gold 9500 in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That gives two people sharing 90cm of width each, the same footprint as two UK singles placed side by side. It's the largest size Harrison Spinks makes in this mattress, and the widest stocked as standard by UK retailers.
Will the Gold 9500 super king fit in my bedroom?
Allow at least 3m x 2.9m so you can open drawers, walk round the bed and fit bedside tables on both sides. That figure is our guidance, not the manufacturer's. In a loft conversion, check the sloping ceiling too: the wall the bed sits against often decides whether a super king works at all.
Is a super king worth it for a restless partner?
Often, yes. The Gold 9500's soft to medium feel and thousands of mini springs already keep movement fairly localised, but distance does more than any comfort layer can. With 90cm each, a partner who turns over frequently is far enough away that you feel very little of it.
Can the Gold 9500 super king get up the stairs?
This is a 29cm-deep pocket spring mattress, so it won't fold or roll the way boxed foam does. At 180cm wide, tight landings and sharp turns are the usual sticking points. Measure your stairwell, door swings and landing before ordering, as this is the hardest size to manoeuvre.
