$172.39
Descripción
A complete silk bedding set built around a 25mm mulberry silk duvet cover, with matching pillowcases and your choice of flat or fitted sheet. Available in six colours and sixteen size configurations spanning EU, UK, and US bed standards — from Twin to Super King.
What Is 25mm Mulberry Silk — and Why Does It Matter?
Momme (mm) is the weight unit used to measure silk fabric density, similar to thread count in cotton. A higher momme means more silk fibre per square metre — a heavier, more durable, more lustrous fabric.
- 12–16mm: Entry-level silk — lightweight, delicate, prone to snagging
- 19mm: Mid-range — suitable for scarves and light apparel
- 22mm: Good quality bedding grade
- 25mm: Premium bedding grade — the weight used in this set. Noticeably heavier drape, richer sheen, and greater longevity than lower-momme alternatives
Mulberry silk specifically refers to silk produced by Bombyx mori silkworms fed exclusively on mulberry leaves. This controlled diet produces the most uniform, fine, and lustrous silk fibre available — the benchmark for luxury bedding worldwide.

How to Choose Your Size
This set uses EU/UK/US bed naming conventions. Use the table below to match your mattress:
| Size Option | Duvet Cover Dimensions | Best For |
|---|---|---|
| Twin 150×200cm | 150 × 200 cm | Single / Twin beds (EU standard) |
| Full 180×220cm | 180 × 220 cm | Full / Double beds (EU/UK) |
| Double 200×200cm | 200 × 200 cm | Standard EU Double / Queen |
| Queen 200×220cm | 200 × 220 cm | EU Queen / UK King |
| Queen 200×230cm | 200 × 230 cm | EU Queen (longer drop) |
| King 220×240cm | 220 × 240 cm | EU King / UK Super King |
| US King 4Pcs / 6Pcs | Approx. 264 × 239 cm | US Standard King (76" × 80" mattress) |
| Cal King 4Pcs / 6Pcs | Approx. 264 × 244 cm | US California King (72" × 84" mattress) |
| Super King 4Pcs / 6Pcs | Approx. 260 × 220 cm | UK Super King (6ft wide mattress) |
If you are between sizes, size up for a fuller drape. Duvet covers are designed to fit the duvet insert snugly — match the cover size to your existing duvet, not just your mattress.
Flat Sheet vs. Fitted Sheet — Which Should You Choose?
| Sheet Type | What It Is | Best For |
|---|---|---|
| Flat Bed Sheet | A rectangular sheet tucked under the mattress or used as a top layer | EU/UK sleeping style; layering between body and duvet; easier to launder |
| Fitted Bed Sheet | An elasticated sheet that wraps around the mattress corners | US sleeping style; stays in place overnight; cleaner look on the mattress |
Both options are made from the same 25mm mulberry silk. The choice is purely functional and regional preference.
4-Piece vs. 6-Piece — What's the Difference?
The only difference is the number of pillowcases. The 4-piece set includes 2 pillowcases (standard for most beds); the 6-piece set includes 4 pillowcases — ideal for larger beds, guest rooms, or those who prefer extra pillowcase coverage.

Care Instructions
- Hand wash preferred — use cool water (30°C / 86°F maximum) with a gentle, pH-neutral detergent formulated for silk or delicates
- Machine wash (if used): delicate/silk cycle only, cold water, mesh laundry bag, no spin
- Do not bleach — bleach and oxidising agents will permanently damage silk fibres
- Do not tumble dry — air dry flat or hang in shade; avoid direct sunlight which causes colour fading and fibre degradation
- Iron on lowest setting (silk setting) while slightly damp, or steam from reverse side only
- Dry clean acceptable — inform your dry cleaner the fabric is 100% mulberry silk
- Storage: store clean, dry, and loosely folded in a breathable cotton bag; avoid plastic bags which trap moisture
Silk is a natural protein fibre. Exposure to perspiration, body oils, and harsh detergents over time will degrade the fabric. Prompt laundering after use extends the life of the set significantly.
Frequently Asked Questions
Is this set suitable for people with sensitive skin or allergies?
Yes. Mulberry silk is a natural protein fibre (fibroin) that is inherently hypoallergenic. It does not harbour dust mites or mould as readily as synthetic or cotton bedding, and its smooth surface reduces friction-related skin irritation. If you have a known sensitivity to animal-derived proteins (rare), consult your dermatologist before use.
Will the colour fade after washing?
Silk dyes are generally stable when cared for correctly. The main causes of colour fading are: exposure to direct sunlight during drying, use of non-silk-safe detergents, and hot water washing. Follow the care instructions above and colours should remain vibrant for years. We recommend washing dark and light colourways separately for the first few washes.
How does this compare to a satin or sateen duvet cover?
Satin and sateen covers are typically made from polyester or cotton woven in a satin weave — they mimic the look of silk but are not silk. Mulberry silk is a natural fibre with genuine temperature-regulating, moisture-wicking, and hypoallergenic properties that synthetic satin cannot replicate. The feel is also distinctly different: silk has a natural warmth and softness that polyester satin lacks.
My mattress is a US Queen (60" × 80"). Which size should I order?
For a US Queen mattress, the Queen 200×220cm or Queen 200×230cm options are the closest match. The 200×220cm gives a standard drop; the 200×230cm gives a slightly longer drop on the sides and foot. For the sheet, a fitted sheet in the Queen 200×220cm size will fit a standard US Queen mattress (60" × 80" / 152 × 203cm) with adequate depth allowance for most mattress profiles up to approximately 30cm deep.
Does the duvet cover come with corner ties to hold the insert in place?
The duvet cover features a hidden zipper closure. Corner ties inside the cover are not confirmed by the vendor for this specific product. If keeping your duvet insert centred is a priority, duvet clips (available separately) can be used through the zipper opening to anchor the insert corners.
