The Harrison Spinks Conrad's fillings read like a fibre glossary: mohair, British wool, cotton, hemp and flax, which means the mattress regulates temperature naturally rather than relying on foam. The listing we sourced shows the Firm tension, though Soft, Medium and Ortho Extra Firm versions are also made. It's a serious investment, but the spring count and all-natural build go some way to explaining the price. If you sleep hot or want a mattress free of synthetic layers, it deserves a close look.

Why should you choose this mattress?
Two things set the Conrad apart. First, the fillings: mohair, cotton, hemp, flax and British wool, layered so the mattress insulates in winter and breathes in summer. Second, the springs: 10,590 of them, combining high-density micro, Posturfil and Cortec pocket springs, and the Cortec technology is 100% recycled and zero waste, which means responsive support with a lighter environmental footprint. Feather & Black offers free two-man delivery to your room of choice, a 100-night comfort promise and a 7-year guarantee, though those terms are the retailer's own rather than Harrison Spinks'. Sizes run from UK Single up to Emperor, so larger bed frames are catered for.
Key features & layer details
Mohair
Soft mohair sits near the sleep surface, which means a luxurious feel underneath you. It also helps regulate temperature through the night.
Wool
Naturally insulating British wool keeps you warm in winter. It's a traditional filling for good reason.
Cotton
Breathable cotton draws heat away in summer. Paired with the wool, it means the mattress adapts across the seasons rather than trapping warmth.
Hemp and Flax
Hemp and flax add further natural loft alongside the mohair, cotton and wool. These plant fibres round out an entirely natural filling stack.
Pocket Springs
10,590 responsive springs form the support core, combining high-density micro, Posturfil and Cortec pocket springs. Each spring moves independently, which means support that follows your shape and less disturbance from a restless partner.

Best suited for?
Warm sleepers
Breathable cotton and temperature-regulating mohair sit in a foam-free filling stack, which means heat is drawn away rather than trapped through summer nights.
Eco-conscious buyers
The all-natural fillings of wool, cotton, hemp, flax and mohair, plus Cortec springs that are 100% recycled and zero waste, keep synthetic layers out entirely.
Couples
Each of the 10,590 pocket springs moves independently, which means support follows each person's shape and you feel less disturbance from a restless partner.
Back sleepers
The Firm tension and a supportive pocket spring core keep your body held level, which suits anyone who likes a mattress that doesn't sink.
Combination sleepers
Responsive micro, Posturfil and Cortec springs react as you move, which means changing position through the night feels easy rather than sticky.
With a premium starting price, this is not a budget buy, and lighter spenders will find capable mattresses for far less. The listed variant is the Firm tension, so lightweight side sleepers may find it a little unforgiving, although Soft and Medium versions exist. If you prefer memory foam, this might not be the best choice: there's no foam here at all.
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.

Does the Harrison Spinks Conrad come with a trial or guarantee?

Six sizes are available: UK Single, Small Double, Double, King, Super King and Emperor.
Is the Harrison Spinks Conrad firm?
The variant on Feather & Black's listing is the Firm tension, though the page doesn't describe exactly how firm it feels. Soft, Medium and Ortho Extra Firm tensions are also available, so most sleeping styles can find a suitable option.
