Inside the Harrison Spinks Classic 2750 you'll find 2,750 springs in total: a core of Cortec Quad springs topped with a layer of MicroHD springs, which means support that responds quickly when you change position. Fillings of wool, hemp and flax give it a breathable, traditional feel. The MattressOnline listing, a little confusingly given this model's 'Firmer Feel' name, gives it a Medium Feel Firmness rating and lists both Medium and Firm options, so check you're ordering the tension you want. It comes in five UK sizes and is handcrafted in the UK.

Why should you choose this mattress?
If you want natural materials rather than memory foam, this is a strong candidate. The wool and viscose cover is naturally fire retardant without chemical treatments, and the wool, hemp and flax fillings breathe well, which means less heat building up overnight. The 2,750-spring construction is genuinely layered: 750 Cortec Quad springs form the core, with 2,000 MicroHD springs above for a more responsive surface feel. At 24cm deep it's a reasonable height without being unwieldy to turn. Yes, seven weeks for free delivery is a long wait, but that reflects a made-to-order, UK-handcrafted mattress rather than one pulled from a warehouse shelf. MattressOnline lists a 100-night trial and 5-year guarantee with it.
Key features & layer details
Cover
Wrapped in high quality wool and natural viscose, fibres that are incredibly soft to the touch. They're also naturally fire retardant, so no chemical treatments are needed.
Comfort fillings
Multiple layers of wool, hemp and flax sit beneath the cover. These natural fibres provide soft, cosy comfort and breathe well.
MicroHD springs
A layer of 2,000 MicroHD springs sits above the core spring unit, which means the surface responds more precisely to your body. It's designed to make the mattress feel more adaptive as you move.
Cortec Quad springs
The core holds 750 Cortec Quad springs, a design that fuses four springs into one pocket. That means increased responsiveness compared with a single spring doing the same job.
Support layers
Two layers of Ecotex fibres, made from recycled materials, sit beneath the springs. They give the spring system a stable base to work from.

Best suited for?
Warm sleepers
Wool, hemp and flax fillings breathe well, which means less heat building up overnight and a cooler, more comfortable night under the covers.
Eco-conscious buyers
The cover is wool and natural viscose, naturally fire retardant without chemical treatments, and the support layers use Ecotex fibres made from recycled materials.
Combination sleepers
A layer of 2,000 MicroHD springs sits above the core, which means the surface responds quickly and precisely whenever you change position in the night.
Back sleepers
A firm feel on a 24cm pocket spring build gives a supportive, springy surface, with Cortec Quad springs in the core for steady responsiveness.
Couples
The core holds 750 Cortec Quad springs, each fusing four springs into one pocket, so the bed responds well and feels stable for two people.
If you like the slow, cradling sink of memory foam, this all-natural pocket spring build will feel too springy for you. And if you need a mattress quickly, the free delivery window of up to seven weeks may rule it out. Anyone wanting a guaranteed firm tension should confirm the option before ordering, as the listing shows a Medium Feel Firmness rating.
