The Cavendish Natural Firm

The firm Natural. The deepest support we build below the flagship.

6,405 individually pocketed springs, the highest count in the Natural range, under 50mm of natural latex and the same wool, cotton, silk, cashgora and horsehair. For back sleepers, heavier frames, larger couples sharing a bed and anyone who wakes up sore on a softer mattress.

Why it matters

• 6,405 individually pocketed springs. Packed tightly enough to hold heavier frames and back sleepers level through the night. Firm without feeling hard.
• Natural fillings, no synthetic foam. 50mm of natural latex beneath wool, cotton, silk, cashgora and horsehair. Natural fillings regulate temperature in a way synthetic foam never quite manages, even with gel infusion. Also the right call if you sleep hot.
• The Vispring and Harrison Spinks answer. Same heritage construction, spring counts in the same range, our manufacturing and our price. I supplied both for over a decade before launching The Sleep Co.
• Three rows of hand side stitching. Reinforced edges, so you can sit and sleep right to the perimeter without the mattress giving way beneath you.
• Handcrafted in Britain. Made in our own factory by a founder-led brand with over 50 years of manufacturing behind it, drawing on a family bed-making heritage going back to 1968.
• 15 year guarantee. White glove delivery anywhere in mainland UK.

Choosing across the three Naturals: Ashbourne is the soft, the deepest cushion. Harrow is the medium, the most universal choice. Cavendish is the firm, the heaviest support layer. Same natural-fibre character, three tensions.

If you're not sure which tension to choose, we'd rather you got it right than rushed. Get in touch and we'll talk through what you sleep on now.
