100% Organic 6000 Ultimate Pocket Spring Wool Mattress

Stephen Day’s Finest Creation | Double-Sided Luxury | Handcrafted with GOTS-Certified Organic Wool

"This is my favourite mattress from the traditional double-sided ranges. I love it because it’s so comfortable — the perfect balance of comfort and support — and I truly believe it’s the finest organic mattress I’ve ever designed and manufactured."
— Stephen Day

The Perfect Combination of Comfort & Support

The Organic 6000 Ultimate is designed to provide indulgent comfort without sacrificing deep, firm support. Thick layers of GOTS-certified British organic wool combine with an advanced 6000 pocket spring system to create adaptive support from surface to core — so that sleeping partners of different heights and weights are equally comfortable and fully supported.

• 2000 Pocket Spring Core – Delivers firm, long-lasting support.

• 4000 Mini Pocket Springs – Cushion the body and provide adaptive comfort for the back, shoulders, and hips in every sleeping position.

• Woollen Sleeping Layers – Naturally breathable and temperature-regulating, offering unparalleled comfort all night long.

Traditional Craftsmanship, Built to Last

Handmade using time-honoured techniques, this mattress is finished with:

• Wool Tufts & 3 Rows of Hand Side Stitching – Ensures durability, shape retention, and a beautifully even sleeping surface.

• 16 Air Vents (8 on single sizes) – Enhance airflow for fresher, more hygienic sleep.

• 4 Sturdy Side Handles – Make turning and rotating simple.

• Double-Sided Design – Flip and rotate to extend the mattress life and maintain lasting comfort.

Pure Organic Luxury – Naturally Healthier Sleep

The 6000 Ultimate contains no foams, no latex, no glues, and no chemical sprays — only nature’s finest materials:

• 2000 GSM 100% Certified Organic British Wool Layers – Exceptional resilience, softness, and comfort.

• 1200 GSM British Lambswool – Adds luxury and long-term durability.

• 100% Egyptian Cotton Cover – With natural fire retardancy and a quilted finish for a seamless sleep surface.

The Benefits of Organic Wool

Stephen insists on organic wool despite its higher cost and difficulty to prepare — because it’s worth it. Wool provides unmatched natural performance:

• Temperature Control – Wicks away moisture, cools you when hot, insulates when cold.

• Hygienic Freshness – Prevents mold, fungi, and bacteria growth.

• Allergy-Friendly – Naturally deters dust mites, reducing asthma and allergy triggers.

• Resilient Comfort – Wool fibres bounce back again and again, ensuring long-lasting support.

A Natural Mattress Experience

When unwrapped, you may notice the gentle fragrance of the countryside — reminiscent of a fresh field with horses. This natural scent quickly dissipates and is entirely harmless — unlike the chemical odours of foam or latex mattresses, which can linger and contain ‘forever chemicals’.

✨ Firmness Options: Available in Medium, Medium Firm, or Firm, achieved by adjusting the ratio of fillers and springs.

The 100% Organic 6000 Ultimate Pocket Spring Wool Mattress is not just another bed — it’s Stephen Day’s masterpiece, combining traditional double-sided craftsmanship, cutting-edge spring engineering, and the finest organic natural materials. A mattress designed to last — and to give you the healthiest, most luxurious sleep possible. - Quite simply the ultimate organic mattress.
