Assessed from the specification published by Feather & Black, captured September 2026, and from regular price comparison across our UK retail partners.
The main reasons to choose the Chaucer are breathability and natural construction. Wool, hemp and flax fillings wick moisture and regulate temperature far better than synthetic foams, which means hot sleepers should notice a real difference. The 5,770-spring system uses two layers of adaptive pocket springs to relieve pressure points while keeping air moving through the mattress. The Cortec springs are 100% recyclable and assembled without glue, a genuine plus if sustainability matters to you. Buying through Feather & Black, you get free two man delivery to your room of choice, a 100-night comfort promise and a 7-year guarantee, though these are the retailer's own terms rather than Harrison Spinks'. It suits back and front sleepers who want firm, traditional support.
Key Features & what's inside
- Top layer. A chemical-free sleeping surface blending British wool and viscose, finished with traditional tufting. The tufts hold the fillings in place, which means less settlement over time, though you will feel a slightly dimpled surface rather than a smooth one.
- Filling. Generous layers of farm-grown hemp, flax and 100% British wool. These natural fibres breathe and wick moisture, which means better temperature regulation than synthetic fillings, especially for hot sleepers.
- Spring system. Over 5,000 high-density micro and Cortec pocket springs, arranged in two layers of advanced pocket springs that adapt to your body and relieve key pressure points. The open structure also lets the mattress breathe, keeping the natural fillings fresh.

Who's it NOT for?
This is a firm tension mattress, so lightweight side sleepers may find it a little too unyielding at the shoulder and hip. If you prefer the contouring hug of memory foam, the springy, traditional feel here will not suit you. And at £1,199 upwards, budget-conscious buyers have cheaper routes to a decent night's sleep.
Harrison Spinks Chaucer Mattress
Is the Harrison Spinks Chaucer mattress firm?
Yes, it's listed as firm tension. That suits back and front sleepers, and heavier bodies generally, although lightweight side sleepers may find it a little too firm for comfortable pressure relief at the shoulder and hip.
How many springs does the Harrison Spinks Chaucer have?
The specifications list 5,770 springs, a mix of high-density micro springs and Cortec pocket springs across two adaptive layers. The product description says over 5,000, so treat 5,770 as the precise figure. The Cortec springs are 100% recyclable and assembled without glue.
What is the Harrison Spinks Chaucer made of?
The fillings are natural: 100% British wool, hemp, flax and viscose, with a chemical-free tufted sleeping surface. Beneath that sit micro and Cortec pocket springs. The mattress is 24cm deep and comes in sizes from UK Single up to Emperor.
Does the Harrison Spinks Chaucer come with a trial and guarantee?
Feather & Black offers a 100-night comfort promise and a 7-year guarantee on this mattress. These are the retailer's own terms rather than Harrison Spinks', so if you buy elsewhere, check what that seller offers before ordering.
Is the Harrison Spinks Chaucer good for hot sleepers?
It should be, yes. Wool, hemp and flax naturally wick moisture and regulate temperature, and the pocket spring construction lets air move through the mattress. There's no foam layer to trap heat, which is often the culprit when a mattress sleeps warm.
