Ask most mattress makers what is inside and the answer is "foam". Ask us and you get a layer list, with weights. Below is every fill we build with — the same list our construction sheets use.
18–21 cm tail hair, washed and teased by hand until it forms an even, springy web. Works as a natural spring, holds air and moves moisture away from the sleeper. Used from 0.5 kg to 3 kg per bed; golden horsehair appears in the XP-025 build.
Wool loft layers and wool tufting balls (80% wool content) buffer temperature in both directions — warm in winter, dry in summer. Naturally fire-resistant and hypoallergenic.
Collected during the natural moulting season — softer, lighter and several times warmer than traditional wool. Blended into the comfort layers of the collection's softest builds.
Light, resilient and exceptionally temperature-stable. Sourced from sustainable partner ranches; used in the Golden Velvet and Imperial Court builds.
Pure cotton pads (400 g) and woven ticking fabrics — the coffee, blue and green checks and the white and blue-white plains. Holds its shape over years of use without dumping or sagging.
Double-cocoon silk, hand-processed to retain its natural sheen and lightness. Appears in selected flagship constructions, layered between the fill for its smooth, temperature-regulating touch.
| Material | Role | What it does in the bed |
|---|---|---|
| Black horsehair 18–21 cm tail hair | Active fill | Washed and teased by hand into an even web. Works as a natural spring, holds air between the fibres and moves moisture away from the sleeper. Used from 0.5 kg up to 3 kg per bed; golden horsehair appears in the XP-025 build. |
| Australian wool | Comfort & climate | Wool loft layers and wool tufting balls (80% wool content) buffer temperature in both directions — warm in winter, dry in summer. |
| Wool–cotton blends | Main comfort fill | The workhorse of every model, layered between ticking and spring unit in weights from 350 g to 900 g per layer. |
| Camel hair & camel down | Luxury comfort | Used in the Golden Velvet and Imperial Court builds; light, resilient and exceptionally temperature-stable. |
| Pure cotton | Structure & breathability | Pure cotton pads (400 g) and woven ticking fabrics — including the coffee, blue and green checks and the white and blue-white plains. |
| Jute felt | Foundation | 500 g jute felt layers sit above and below the spring units, and the Tatami build rests on a 7 cm S-grade jute platform. Firm, dry, and naturally resilient. |
| Soy & high-loft fibres | Resilient loft | Soy-based and high-loft resilient fibres add the immediate "new bed" bounce above and below the spring unit. |
| Lyocell fabrics | Ticking | Silk-smooth cellulose ticking in apricot, pink and clover prints for the Diamond Lattice, Natural Essence and Cloud Cotton builds. |
| Dupion silk | Luxury fill | Double-cocoon silk appears in selected flagship constructions for its natural sheen and lightness. |
| Calico pocket springs | Support | Individually sewn fabric pockets, from 1.0 mm nested mini-springs to 2.0 mm full-depth units in 33×38 and 46×52 arrays. Hand-sewn linen-encased units appear in the Golden Velvet builds. |
| Mini bread-loaf springs | Top elasticity | Small-diameter nested spring units (1.0–1.4 mm wire) inside two-tier cores and the Tatami platform, adding point elasticity under the main unit. |
Material and emission testing through independent third-party laboratories (SGS report set). Buyers receive the reports with every quotation.
Fire-performance construction is engineered for the destination market — UK BS 7177, US 16 CFR 1632/1633, or EN 597 for Europe — before the first bed is sewn.
Horsehair, wool, camel hair and silk are animal-derived. We supply the origin and processing documentation destination customs need — tell us the market early so the paperwork travels with the goods.
