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.

- 75cm each for two sharers: Two of you get 75cm of width apiece, which means room to settle at the shoulders and hips without crowding each other on the softer surface.
- Individually pocketed springs limit disturbance: The Cortec Quad Revolution springs are pocketed individually, which means an early riser slipping out at six can leave the other side largely undisturbed.
- 200cm of length for taller sleepers: At 6ft 6in long, the UK king adds 10cm over the UK double, a real difference if either of you is approaching six foot.
- Softness works better with space: A soft to medium feel invites side sleeping and position changes through the night, and the wider surface gives you the room to actually do it.
- Breathable natural fillings across a bigger surface: Wool, hemp, flax and cotton keep heat from pooling, useful when two bodies share one mattress every night.
This size suits you if...
You share the bed every night and a UK double has started to feel like a negotiation, or one of you keeps odd hours and you want the mini springs and extra width to absorb the comings and goings. It also fits if either sleeper is tall, since the 200cm length is 10cm more than a UK double, and your room meets our suggested minimum of 2.7m x 2.9m.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives a solo sleeper generous space.

Is a UK king big enough for a couple on the Harrison Spinks Gold 9500?
Yes, comfortably for most. You get 75cm of width each, and because this mattress has a soft to medium feel that cradles rather than resists, that space lets each of you sink in without rolling towards the middle. If one of you sprawls, or a dog claims a corner most nights, consider the UK super king instead.
Will I feel my partner getting up in the Gold 9500 UK king?
Less than you might expect. The springs are pocketed individually and the Posturfil mini springs react to movement locally, so someone leaving for an early shift disturbs mainly their own side. Across 150cm of width there's also simple distance between you, which does a lot of the work on its own.
Is the UK king long enough for a tall sleeper?
At 200cm, the UK king suits sleepers approaching six foot who find their feet at the edge of a 190cm UK double. The extra 10cm of length is often the real reason to size up, more than the width. The UK super king is the same length, so going bigger again only adds width.
What room size do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m, which allows walking space on both sides and room for doors and drawers to open. A new build master bedroom can shrink quickly once fitted wardrobes go in, so measure the usable floor rather than the plan. If your room is tighter, the UK double needs at least 2.6m x 2.8m.
