In the king size, the Harrison Spinks Pure Splendour Firm holds 11,000 springs, combining 2,500 micro springs with the Advanced Cortec spring-within-a-spring system, which means cushioning at the surface with deeper, responsive support underneath. It's firm, so it suits people who want a properly solid feel rather than a plush one. It's serious money, although the natural, traceable materials and in-house construction go some way to explaining it.

Why should you choose this mattress?
Choose this if you want a firm mattress built from natural materials rather than foam. The fillings are fully traceable, with wool, hemp and flax grown on the brand's own farm, and the wool-blend cover is fire retardant without chemical treatments, which means fewer synthetics next to your skin. The spring system is where the money goes: 2,500 micro springs sit over the Advanced Cortec pocket springs, so you get pressure relief without losing the firm support. Furniture Village lists a 20-year guarantee, notably longer than most brands offer, though that's the retailer's stated term. It comes in four sizes, from UK Single to Super King, but there's no standard Double.
Key features & 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.

Best suited for?
Back sleepers
The firm feel and Advanced Cortec pocket springs give solid, responsive support underneath, which means your body stays held up rather than sinking in.
Warm sleepers
Wool, hemp, flax and cotton fillings are natural fibres that help regulate temperature, which means a more comfortable night if you tend to run hot.
Eco-conscious buyers
Fully traceable wool, hemp and flax grown on the brand's own farm, plus a cover that is fire retardant without chemical treatments, mean fewer synthetics.
Heavier sleepers
The spring-within-a-spring design responds differently to lighter and heavier pressure, so a firm mattress with 2,500 micro springs on top still adapts as you move.
Combination sleepers
Responsive Cortec springs adapt as you move, while the micro spring layer keeps the surface cushioned, which means changing position feels easy on a firm base.
This is a genuinely firm mattress, so lightweight side sleepers may find it too unyielding at the shoulder and hip. It's also a significant spend, and there's no standard UK Double size, only Single, Small Double, King and Super King. If you prefer a sink-in, cradling feel, look elsewhere.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

What is the Harrison Spinks Pure Splendour Firm mattress made of?
Natural materials throughout: British wool, hemp and flax grown on the Harrison Spinks farm, plus cotton, under a wool and viscose blend cover woven in-house. Support comes from the Advanced Cortec pocket spring system topped with a micro spring layer. It's 29cm deep.
How many springs does the Pure Splendour Firm mattress have?
The Furniture Village listing states 11,000 springs, though this figure applies to the king size specifically. That includes 2,500 micro springs plus the Advanced Cortec pocket springs. Spring counts for other sizes aren't stated on the listing.
Does the Harrison Spinks Pure Splendour Firm come with a guarantee?
Furniture Village lists a 20-year guarantee, which is longer than most brands offer. Bear in mind this is the retailer's stated term, so check the terms at your point of purchase before buying.
