The Vispring Heybrook has over 2,800g of hand-layered natural fillings, including South American horsetail, Shetland wool, Mulberry silk and mohair. The firmness is stated as firm, so this suits sleepers who want proper resistance rather than a soft, sinking feel. At 23cm it's slimmer than its price might suggest, although depth here reflects dense natural materials rather than airy foam. Available in UK Double, King and Super King.

Why should you choose this mattress?
Everything in the Heybrook points to longevity and breathability. Each spring sits in a cotton calico pocket, which means the springs move independently to follow your shape while air passes through the mattress freely, useful if you sleep warm. The natural fillings do the temperature work too: horsetail is springy and durable, wool regulates heat, and silk and mohair add a slightly softer surface feel above the firm core. Feather & Black lists a 30-year guarantee, far longer than most brands offer, though exclusions apply, notably around using a slatted base without a Vispring Mattress Pad. An integrated insulator pad means it works on a slatted bedstead or a sprung base. Feather & Black also offers free delivery on all orders.
Key features & layer details
Natural fillings
Over 2,800g of natural fillings layered by hand, including South American horsetail, real Shetland wool, Mulberry silk and mohair. These materials breathe well and regulate temperature, which means less of the clammy warmth you can get with synthetic fillings.
Spring core
High-tensile vanadium steel springs, each one hand-nested and placed in a breathable cotton calico pocket. Individually pocketed springs respond to each sleeper separately, so you feel less movement from a partner turning over.
Spring insulator pad
An integrated insulator pad sits with the spring unit to keep support consistent. It means the mattress performs properly on either a slatted bedstead or a sprung base.

Best suited for?
Warm sleepers
Wool regulates heat and the cotton calico pockets let air pass freely, which means less of the clammy warmth synthetic fillings can trap.
Couples
Individually pocketed springs respond to each sleeper separately, so you feel less movement when your partner turns over during the night.
Back sleepers
The firm feel and dense natural fillings give proper resistance rather than a soft, sinking sensation, which suits anyone who prefers a flatter, more supported position.
Heavier sleepers
Over 2,800g of dense horsetail, wool and mohair sit over hand-nested vanadium steel springs, giving firm, durable support that should resist sinking.
Adjustable beds
An integrated spring insulator pad keeps support consistent, so the mattress works on a slatted bedstead or a sprung base.
This is a firm mattress, so lightweight side sleepers may find it presses on shoulders and hips rather than cushioning them. And with a premium starting price, it's out of reach for most budgets. It's also made to order, so anyone needing a mattress quickly should look elsewhere. No Single size is listed either.
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 Vispring Heybrook mattress?
It's listed as firm. That suits back and stomach sleepers, and heavier bodies that need more pushback. Lighter side sleepers may find it a little too unyielding at the shoulder and hip.
How many springs does the Vispring Heybrook have?
The Feather & Black listing states 2,110 pocket springs. Each spring is made from high-tensile vanadium steel, hand-nested and held in a breathable cotton calico pocket, so the springs work independently rather than as one linked sheet.
What is the Vispring Heybrook made of?
Over 2,800g of natural fillings, hand-layered: South American horsetail, real Shetland wool, Mulberry silk and mohair. These sit above vanadium steel springs in cotton calico pockets. The mattress is 23cm deep.
Does the Vispring Heybrook come with a guarantee?
The Feather & Black listing states a 30-year guarantee, with an asterisk noting exclusions apply, including use on a slatted base without a Vispring Mattress Pad. Check the full terms with the retailer before buying, especially if you have a slatted bedstead.
Can you use the Vispring Heybrook on a slatted bed base?
Yes, it has an integrated spring insulator pad designed to give proper support on either a slatted bedstead or a sprung base. Be aware, though, that the listed guarantee has exclusions around slatted bases used without a Vispring Mattress Pad.
