Layer Details
- Cover. A wool-blend cover woven in-house, fire-retardant without chemical treatments. That matters if you're sensitive to sprays or simply prefer fewer chemicals near your skin.
- Fillings. Responsibly sourced, fully traceable British wool, hemp and flax grown on the Harrison Spinks farm, alongside soft cotton. Natural fibres like these breathe well, which means less overnight heat build-up than foam.
- Micro springs. A layer of 2,500 high-density micro springs sits near the surface for pressure relief and cushioning. You feel this as a gentler, more contouring top layer before the main support kicks in.
- Pocket springs. The award-winning Advanced Cortec pocket spring system uses a spring-within-a-spring design for dynamic support. In practice, the mattress responds gently to light pressure and more firmly as you sink deeper.

- 90cm each for two sharing: Two people get 90cm each, which means a partner who turns all night becomes far easier to sleep through.
- Dual tension on this size: The UK super king can be ordered with medium on one side and firm on the other, so a couple with different preferences stops compromising.
- Room for night-time visitors: At 6ft x 6ft 6in, a child who wanders in at 3am or a large dog with settled habits leaves everyone with a workable share of the bed.
- Natural fillings across a wide surface: British wool, hemp, flax and cotton breathe better than foam, which matters more when three or four bodies are generating heat under one duvet.
- Distance as a comfort feature: The micro spring layer cushions movement, but on a UK super king the sheer space between you does most of the work.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your partner is genuinely restless and you've decided distance is the fix, or children and pets treat your bed as theirs too. It also suits couples who want different firmness on each side, since dual tension is available in this size, provided your room comfortably clears 3m x 2.9m.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you'd struggle to walk round the bed. We'd recommend the UK king instead: 30cm narrower, the same length, and it needs at least 2.7m x 2.9m.

Can I get the Pure Splendour super king in dual tension?
Yes. The UK super king is one of the two sizes Harrison Spinks offers in dual tension, so one side can be medium and the other firm. If you and your partner have argued over firmness for years, this size solves it without either of you sleeping on the wrong feel.
What room size do I need for a super king Pure Splendour?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable rather than cramped. Measure with the door swing and any wardrobes in mind, because a 180cm wide mattress dominates a room in a way a UK king does not. In a period property or large master it looks in proportion.
Is the super king Pure Splendour worth it over the king?
The UK super king is 30cm wider than the UK king and the same length, so the entire gain goes into elbow room. If a restless partner wakes you, or children climb in most mornings, that extra width does more for your sleep than any comfort layer. In a smaller room, the UK king is the sensible call.
Is a super king big enough for sharing with children?
It copes better than any other standard size. Two adults get 90cm each, so a small visitor at night squeezes rather than ruins things. The natural wool, hemp and cotton fillings also breathe well, which helps when extra bodies push the temperature up. It won't replace their own bed, but occasional company works.
