Thickened 3D Down-Filled Mattress Topper.
A thickened, 3D down-filled mattress topper with a lamb wool surface — available in five colours and seven sizes from 90 × 200 cm to 200 × 220 cm. The sleep upgrade that adds genuine warmth and cushioned depth to any bed without the cost of a full mattress replacement.
Laid over an existing bed base or dormitory frame, the thickened 3D down fill adds the cushioned depth and pressure relief of a proper mattress topper without the weight, cost, or logistics of replacing the mattress itself. The sleep upgrade that makes a hard or thin surface feel comfortable rather than institutional and bare.
The lamb wool outer surface adds a tactile warmth and softness that a standard cotton or polyester cover cannot — the finish that makes the topper read as a considered bedroom piece rather than a functional item, holding its texture through regular use and washing without pilling or flattening.
Pure Grey, Pure White, Pure Yellow, Sheep Ash, and Alpaca cover the full range from neutral and minimal to warm and textured — each colour works across modern, Scandinavian, and traditional bedroom schemes, with consistent sizing across all colourways for easy restocking or wholesale ordering.
From 90 × 200 cm for a single dormitory bed to 200 × 220 cm for a wide double or king, the seven size options cover every standard UK and export bed frame without cutting or adapting — the wholesale-ready range that makes bulk ordering across student accommodation, hotel, or retail catalogues simple and consistent.
- Machine wash on a gentle or delicate cycle at 30°C. Do not wash at high temperatures — excessive heat can damage the down fill and cause the lamb wool surface to felt or shrink.
- Use a mild, wool-safe detergent. Avoid biological detergents, fabric softeners, or bleach, which can break down natural fibres and affect the loft of the fill.
- Wash alone or with similar light bedding items — avoid washing with heavy items such as jeans or towels that can compress and unevenly distribute the fill.
- Tumble dry on a low heat setting with two or three dryer balls to redistribute the down fill and restore loft as it dries. Do not line-dry flat — the fill can clump and settle unevenly.
- Ensure the topper is completely dry before returning it to the bed. Damp fill can develop odour and mildew if covered while still wet.
- Spot-clean minor marks between washes with a damp cloth and mild detergent, then blot dry and allow to air fully before use.
- Select the size that matches your bed frame or mattress dimensions — refer to the size guide below. The topper lies flat on top of the mattress and is secured by a fitted sheet placed over the top.
- Place the lamb wool surface face-up. The textured surface faces the sleeper; the smoother underside sits against the mattress.
- Secure with a deep-pocket fitted sheet pulled over both the topper and the mattress to prevent movement during sleep. A sheet with a depth of at least 30 cm is recommended for thicker combinations.
- Allow the topper to air for 30–60 minutes after unpacking before making the bed — the fill will expand and settle to its full depth once released from packaging.
- Store in a cool, dry, well-ventilated space — a breathable cotton storage bag is preferable to a sealed plastic bag, which can compress the fill permanently and trap moisture.
- Do not store under heavy items or in a tightly compressed state for extended periods, as this can reduce the loft and cushioning of the down fill over time.
- Air the topper outdoors on a dry, breezy day every few months to refresh the fill and maintain loft between washes.
- Keep away from damp environments — moisture can cause natural fibre fill to clump, develop odour, or degrade more quickly than in dry conditions.
Match the topper size to your mattress or bed frame dimensions. If your mattress falls between two sizes, select the larger size for full coverage.
