At 21cm deep, the Feather & Black Harewood is shallower than many modern mattresses, which means it suits shallower fitted sheets and divans but may feel a little slimline if you're used to a chunkier build. Inside you'll find individually wrapped pocket springs, deep polyester comfort layers and a soft-touch damask cover with an antibacterial finish. Feather & Black offer free two man delivery to your room of choice, plus what they call a 100 Night Comfort Guarantee, so you can try it at home before committing.

Why should you choose this mattress?
The Harewood's main draw is its firm tension paired with individually wrapped pocket springs, which means solid support with less motion transfer than an open coil bed, useful if a restless partner tends to wake you. The soft-touch damask cover has an antibacterial finish, a sensible touch for allergy-conscious sleepers, and the natural cover is designed for breathability. Yes, the comfort layers are polyester rather than natural fillings, but that helps keep the price down. Free delivery on all orders includes two man delivery to your room of choice, and the 100 night trial gives you a proper chance to settle in. The one year guarantee is short.
Key features & layer details
Cover
A sumptuously soft natural cover designed for enhanced breathability, which means heat can escape rather than build up around you. It also carries an antibacterial finish.
Comfort layers
Deep polyester comfort layers sit beneath the cover. These provide the cushioning you feel first, softening the firm springs slightly at the surface.
Springs
The support core uses individually wrapped pocket springs, 800 of them in the king size. Each spring moves independently, which means less disturbance when a partner turns over.

Best suited for?
Couples
Individually wrapped pocket springs move independently, which means less disturbance when a restless partner turns over, so you are less likely to be woken.
Back sleepers
The firm tension and pocket spring core give solid, steady support, while the polyester comfort layers soften the surface slightly for a comfortable feel.
Allergy sufferers
The soft-touch damask cover carries an antibacterial finish, which is a sensible extra if you are particular about what you sleep on.
Warm sleepers
The natural cover is designed for breathability, which means heat can escape rather than build up around you through the night.
Heavier sleepers
A firm tension with 800 individually wrapped pocket springs in the king size gives a supportive feel that suits those who prefer a less yielding bed.
This is a firm tension mattress, so lightweight side sleepers may find it a little too unyielding on the shoulder and hip. If you want natural fillings such as wool, the polyester comfort layers won't suit. And at 21cm deep, it may feel low-profile on a tall bed frame.
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 Feather & Black Harewood mattress?
Feather & Black describe the Harewood as a firm tension mattress. That generally suits back and front sleepers, and heavier builds who need more pushback. Lightweight side sleepers may find it slightly too firm for comfortable pressure relief at the shoulder.
How many springs does the Harewood mattress have?
Feather & Black's page states 800 individually wrapped pocket springs in the king size, while the specification lists 930, which appears to relate to the Super King. Spring counts vary by size, so check the figure for the size you're buying.
Does the Feather & Black Harewood come with a trial?
Yes. Feather & Black offer what they call a 100 Night Comfort Guarantee, so you can sleep on the Harewood at home for up to 100 nights. The mattress also comes with a one year guarantee, which is shorter than many brands offer.
Is delivery free on the Feather & Black Harewood?
Yes, Feather & Black offer free delivery on all orders, including two man delivery to your room of choice. Anticipated delivery is within 14 days after the product arrives at the delivery depot.
What sizes does the Harewood mattress come in?
The Harewood is available in five UK sizes: Single, Small Double, Double, King and Super King.
