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.

- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who turns over frequently becomes far easier to sleep through.
- Space for the whole household: When children pad in at 3am or the dog claims the foot of the bed, this size means nobody ends up clinging to an edge.
- Natural fillings across a bigger surface: The wool, hemp and flax layers breathe well, so even with three bodies radiating heat there's more mattress to spread that warmth across.
- Springs that respond to each sleeper: The pocketed spring layers react to each person independently, which means movement on one side of this wide surface barely registers on the other.
- The right scale for large bedrooms: In a generous master or period property, a UK super king fills the space in a way smaller sizes cannot.
This size suits you if...
You share the bed every night and one of you is a genuinely restless sleeper, or your children or pets treat your bed as their own and you want everyone to keep a fair share. It also fits if you have a large master bedroom where a UK king would look a little lost, and you want the widest size stocked as standard.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for this size. The UK king is 30cm narrower at the same length and needs at least 2.7m x 2.9m, so we'd recommend the UK king instead.

What size room do I need for the Gold 9500 super king?
We suggest a minimum of 3m x 2.9m, and around 3.5m x 3.2m feels right in practice. That allows walking space on both sides and clearance for the door swing. Measure with wardrobes and drawers open, because a mattress this wide changes how the whole room works, and check any landing turns before ordering.
Is a super king Gold 9500 worth it for a restless partner?
Distance does more than any comfort layer here. With 90cm each for two people sharing, most turning and fidgeting happens too far away to wake you, and the individually pocketed springs respond to each sleeper separately rather than transmitting movement across the bed. If disturbed sleep is your main complaint, this size addresses it directly.
Will the Gold 9500 in a UK super king get up my stairs?
This is a traditional pocket spring mattress with natural fillings, so it arrives full size rather than rolled, and at 180cm wide it's the hardest standard size to manoeuvre. Measure your stairwell, landing turns and bedroom door before buying, particularly in older properties with tight winders.
How does the super king compare with the UK king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. The construction is identical, so the choice comes down to space: the extra width is what makes sharing with children or pets workable. The UK king needs at least 2.7m x 2.9m, slightly less room than the super king.
Is the Gold 9500 super king big enough to share with children?
It's the most practical standard size for it. At 180cm wide, a couple plus a small visitor can usually all settle without anyone hanging off the edge, and the springs cushion each person independently. It won't replace a proper family bed arrangement long term, but for the occasional 3am arrival it copes well.
