The Harrison Spinks Tennyson contains 7,440 springs across several layers, which means the support adjusts to your shape rather than pushing back in one flat plane. Above them, British wool, flax and hemp handle temperature and moisture, and a pillow top with micro springs softens the surface feel. It comes in sizes from single up to emperor. It's a considered choice for people who want natural fillings and firm support, although lightweight side sleepers may find it a little too firm for comfortable pressure relief.

Why should you choose this mattress?
You'd choose the Tennyson for the combination of a genuinely high spring count and natural fillings without foam-heavy layers. The 7,440 springs, including micro, Posturfil and Cortec pocket springs, give fine-grained support, which means less of that roll-together feeling if you share a bed. British wool comes with full traceability from farm to factory, and the flax and hemp fillings breathe well, so hot sleepers should stay more comfortable than on synthetic alternatives. Yes, it's a serious spend, but you're paying for Harrison Spinks construction and a 30cm build. Feather & Black, the retailer that sells it, lists a 100-night comfort promise and a 7-year guarantee, so there's a safety net.
Key features & layer details
Pillow top
A cloud-like pillow top with additional micro springs, which means a softer, cushioned surface sitting above the firm support below. It's sewn on rather than separate, so the comfort layer stays put.
Natural fibres layer
Generous layers of British wool, naturally cooling flax and farm-grown hemp. These fibres wick moisture and regulate temperature, which should help if you tend to sleep warm.
Pocket spring layers
7,440 responsive springs in total, combining high-density micro, Posturfil and Cortec pocket springs. Each spring moves independently, so you get support where your body needs it and less motion transfer across the bed.

Best suited for?
Couples
Independently moving pocket springs, including micro, Posturfil and Cortec types, mean less motion transfer, so one person turning over is less likely to disturb the other.
Warm sleepers
British wool, flax and hemp wick moisture and regulate temperature, which should keep you more comfortable through the night than synthetic fillings would.
Eco-conscious buyers
Natural fillings of British wool, flax and hemp, with the wool traceable from farm to factory, mean you avoid foam-heavy layers and know where materials come from.
Back sleepers
Firm support from 7,440 springs adjusts to your shape, which means your body stays supported along its length instead of being pushed back in one flat plane.
Heavier sleepers
Several layers of pocket springs and a firm feel give plenty of support, while the sewn-on pillow top adds cushioning that stays in place.
This is a firm mattress, so lightweight side sleepers may find it doesn't cushion the shoulder and hip enough. It's also a significant outlay: if your budget sits well under the starting price, you'll find good pocket sprung options elsewhere. And at 30cm deep, check your fitted sheets will cope.
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.

FAQ's
How firm is the Harrison Spinks Tennyson mattress?
It's described as firm. The pillow top with micro springs softens the immediate surface feel, but the underlying support is firm, which suits back and front sleepers and heavier builds. Lightweight side sleepers may find it slightly too firm.
How many springs does the Harrison Spinks Tennyson have?
It contains 7,440 springs in total, made up of high-density micro springs, Posturfil pocket springs and Cortec pocket springs, plus additional micro springs in the pillow top. More springs generally means more precise contouring and less partner disturbance.
Does the Harrison Spinks Tennyson come with a trial or guarantee?
Feather & Black, the retailer that sells it, lists a 100-night comfort promise and a 7-year guarantee as its own offers. The mattress is made exclusively for Feather & Black, so those terms come from that retailer rather than from Harrison Spinks directly.
What sizes does the Harrison Spinks Tennyson come in?
Six sizes: UK single, small double, double, king, super king and emperor. The mattress is 30cm deep across the range, so deep fitted sheets are a sensible buy.
What is the Harrison Spinks Tennyson made of?
The fillings are natural: British wool with full farm-to-factory traceability, flax and hemp, over layers of pocket springs. The cover is a wool and viscose blend. There's no memory foam, which means a more breathable, springier feel than foam-topped mattresses.
