Choose this if you want a genuinely firm mattress built from natural materials rather than synthetic foams. The Cortec Revolution Quad spring system uses a spring-within-a-spring design, which means the support adapts as you move rather than feeling like one flat, rigid surface. Layers of 2,500 and 4,000 high-density micro springs sit above the main 1,000 Posturfil pocket springs, so the firmness comes with a surprisingly refined surface feel. Wool, hemp, flax, cotton and mohair fillings help with temperature regulation, useful if you sleep warm. The £2,799 price is steep and it's only listed in UK King, but for a firm, natural-filled mattress this is craftsmanship you can feel.
Key Features & what's inside
- Pillowtop. A pillowtop containing springs, cotton, wool and mohair. This gives a soft initial surface feel before you reach the firm support beneath.
- Advanced Cortec Revolution Quad pocket spring system. An award-winning spring-within-a-spring design providing dynamic support that adapts to your body. In practice, that means support that responds to your shape rather than pushing back uniformly.
- Posturfil pocket springs. 1,000 Posturfil pocket springs form the core support layer. Each spring moves independently, which helps reduce disturbance when your partner moves.
- High-density micro springs. Layers of 2,500 and 4,000 high-density micro springs. These fine springs contour more closely to your body than the larger springs below.
- Natural fillings. Wool, hemp, flax, cotton and mohair. Natural fibres like these breathe better than foam, which helps if you tend to overheat at night.

Who's it NOT for?
This is a firm mattress, so lightweight side sleepers may find it doesn't allow enough sink at the shoulder and hip, even with the pillowtop. It's also only listed in UK King, and at £2,799 it's out of reach if you're shopping on a modest budget.

View all mattresses
How many springs does the harrison spinks pure grande pillowtop have?
It has 12,500 springs in total, combining 1,000 Posturfil pocket springs, layers of 2,500 and 4,000 high-density micro springs, the Cortec Revolution Quad spring-within-a-spring system, and springs within the pillowtop itself.
How firm is the harrison spinks pure grande pillowtop mattress?
It's rated Firm. The pillowtop softens the initial feel slightly, but the underlying support is firm, so it suits back and front sleepers or anyone who prefers a solid, supportive surface. Lightweight side sleepers may find it a little too firm.
Does the harrison spinks pure grande pillowtop come with a guarantee?
Furniture Village, which lists this mattress, offers a 20-year structural guarantee on it. That's the retailer's own offer, so if you buy elsewhere, check the terms with that seller before ordering.
How deep is the harrison spinks pure grande pillowtop mattress?
It's 33 cm deep, which is noticeably deeper than a standard mattress. Check that your fitted sheets are deep enough, as many standard sheets won't stretch to fit a mattress of this depth.
What is the harrison spinks pure grande pillowtop made of?
It's a pocket spring mattress with natural fillings: British wool, hemp, flax, cotton and mohair, topped with a wool and viscose blend cover. There's no memory foam, which means better breathability and a more responsive feel.
