Layer Details
- Cover. A wool-blend cover woven in-house, fire retardant without chemical treatments. That means natural flame resistance rather than sprayed-on chemistry.
- Fillings. Responsibly sourced, fully traceable British wool, hemp and flax grown on the Harrison Spinks farm, alongside soft, breathable cotton. Natural fibres like these help regulate temperature, which matters if you tend to sleep warm.
- Micro springs. A layer of 2,500 high-density micro springs, which means the surface can contour to your shoulders and hips even though the overall feel is firm. It's cushioning without softness, in effect.
- 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 differently to lighter and heavier pressure, adapting as you move.

- Distance beats any comfort layer: With 90cm each for two people sharing, movement on one side simply happens too far away to wake you, whatever your partner gets up to.
- Firm support across the full width: The Advanced Cortec spring-within-a-spring system responds to lighter and heavier pressure, so an adult and a child sharing each get support suited to their weight.
- Natural fillings over a big surface: British wool, hemp and flax help regulate temperature, useful when three bodies and a duvet are generating heat across 180cm of bed.
- Room for the whole household: If children or pets treat your bed as theirs, the extra width means everyone keeps a genuine share rather than one adult clinging to the edge.
- A scale that fits large rooms: In a generous master bedroom a smaller size can look lost; at 180 x 200cm this fills the space properly, and we suggest a room of at least 3m x 2.9m.
This size suits you if...
You share the bed every night and want enough width that neither of you feels the other move, your children or pets regularly end up in with you, or your master bedroom is large enough that a UK king would look undersized. You'll also need to like a genuinely firm feel, because that doesn't soften at any width.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest 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.

Does the Harrison Spinks Pure Splendour Firm come in a UK super king?
Yes. The UK super king measures 180 x 200cm, or 6ft x 6ft 6in, and is the largest size this mattress comes in. It's 29cm deep, so factor that into bedding: standard super king fitted sheets fit, but check the depth on any you already own. Compare the retailers listed on this page for live prices.
Is the UK super king worth it over the UK king for this mattress?
If you share the bed, usually yes. The UK super king is 30cm wider than the UK king and the same length, and that extra width is what turns a restless partner from a nuisance into background noise. The trade is space: we suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king.
How much room does each person get on the Pure Splendour Firm super king?
Two people sharing get 90cm each, which is the width of a single bed apiece. Combined with the Advanced Cortec springs, which respond to lighter and heavier pressure independently, you're unlikely to feel your partner turn over. If one of you is notably restless, the width does more for your sleep than any comfort layer could.
Is the UK super king a good size for sharing with children or pets?
It's the size we'd point families to. With 180cm of width, a child wandering in at 3am doesn't have to cost an adult their share of the bed, and the firm feel keeps everyone supported rather than rolling into a dip in the middle. A large dog with bed privileges is easier to live with at this width too.
What room size do I need for the Pure Splendour Firm in a UK super king?
We suggest a room of at least 3m x 2.9m, which is our guidance rather than the manufacturer's, and leaves walking space around the bed and both bedside tables. Before ordering, check the awkward points too: door swing into the room, tight landing turns and any stairs the mattress has to come up.
