Vintage Roses Grade 6A Mulberry Silk Cushion Cover

Grade 6A is the highest purity classification for mulberry silk. It means the silk has been reeled from the finest, most uniform cocoons, producing the longest, smoothest and most lustrous fibres available. Most mass-market products use Grade A or Grade 3A silk. Jass London uses only Grade 6A mulberry silk across every pillowcase and cushion cover – which is why the drape, smoothness and durability are noticeably superior to what you find at lower price points.

Yes, and the mechanism is straightforward. Cotton pillowcases have microscopic rough fibres that catch your hair as you move during sleep, creating friction that causes breakage, split ends and frizz. Grade 6A mulberry silk has an exceptionally smooth surface that lets hair glide without resistance. The result: less breakage, significantly less morning frizz, and longer-lasting blowouts and styles. The benefits are especially noticeable for curly, wavy, colour-treated or chemically processed hair. Most customers report visible improvement within two to four weeks of switching.

Yes. Silk offers two key skin benefits cotton cannot match. First, the smooth surface dramatically reduces friction, meaning less mechanical stress on facial skin overnight – a contributing factor to sleep creases and, over time, wrinkle formation. Second, unlike cotton, silk does not absorb moisture from your skin. Cotton wicks hydration and skincare away from your face while you sleep; silk leaves them where they belong. For skin prone to sensitivity, redness or breakouts, silk's hypoallergenic, temperature-regulating properties make it a genuinely gentler overnight surface.

This is one of the most common points of confusion in bedding. Satin is a weave structure, not a fibre – satin pillowcases are almost always made from polyester, which is a synthetic, plastic-derived material. Silk is a natural protein fibre. Polyester satin traps heat, does not breathe, and lacks the amino acid proteins that give real silk its hair and skin benefits. Mulberry silk is naturally temperature-regulating, naturally hypoallergenic, and genuinely smooth at a molecular level. Jass London pillowcases are 100% Grade 6A mulberry silk charmeuse – no synthetics, no shortcuts.

Hand washing is ideal but not strictly necessary. You can machine wash Jass London silk on a silk or delicate cycle at 30°C, inside a mesh laundry bag. Use a gentle, pH-neutral detergent such as Woolite or a dedicated silk wash – never standard biological detergent, bleach or fabric softener, as these break down silk's natural proteins. Do not wring or tumble dry. Lay flat or hang to dry away from direct sunlight. If ironing, use the lowest silk setting while slightly damp and iron on the reverse side. With this routine, your pillowcase will hold its lustre and softness for years.

With correct care, Jass London silk pillowcases and cushion covers typically last two to three years of regular use. Because we use Grade 6A mulberry silk woven at 16.5 momme, the fabric is denser and more resilient than lighter-weight silk products. Many customers with repeat orders report their original pieces still looking and feeling beautiful after three years. The key factors are washing at 30°C or below, avoiding harsh detergents, and drying away from direct sunlight.

Yes. Mulberry silk is naturally hypoallergenic. It is inhospitable to dust mites, mould and fungal growth – three of the most common triggers for night-time allergies, congestion and skin irritation. Unlike down or feather bedding, silk does not harbour these allergens. It is also a naturally breathable, temperature-regulating fibre that does not create the warm, moist environment allergens thrive in. For people with sensitive skin, eczema or allergies, a Jass London Grade 6A mulberry silk pillowcase is one of the most beneficial choices for overnight bedding.

Not exactly – they describe different things. Mulberry silk refers to the origin of the fibre: it is produced by silkworms fed exclusively on mulberry leaves, resulting in the finest, most consistentsilk available. Charmeuse refers to the weave structure: a satin-type weave that produces a smooth, lustrous face and a matte underside. Jass London pillowcases and cushion covers are made from Grade 6A mulberry silk woven in a charmeuse structure – you get both the highest-quality fibre and the smoothest, most skin-friendly surface.

Yes, you can machine wash Jass London silk pillowcases. Use a silk or delicate cycle at 30°C, place the pillowcase inside a mesh laundry bag, and use a gentle, pH-neutral detergent. Avoid biological detergents, bleach and fabric softener. Do not spin at high speed. After washing, remove promptly and lay flat or hang to dry away from direct sunlight – never tumble dry. Following this routine means you can wash your silk regularly without compromising the fabric's quality or longevity.

Yes, and it is one of the most immediate benefits customers notice. Frizz is largely caused by friction: as hair moves against a rough cotton surface during sleep, the outer cuticle layer of each strand is roughed up, causing frizz and flyaways by morning. The ultra-smooth surface of Grade 6A mulberry silk charmeuse creates minimal friction, leaving the hair cuticle intact overnight. Customers with naturally curly, wavy or frizz-prone hair typically notice a significant reduction in morning frizz within the first week of switching to a Jass London silk pillowcase.

For two reasons, yes. The practical one: silk cushion covers hold their shape, colour and lustre far longer than cotton or polyester alternatives. They are cool to the touch year-round and feel genuinely different to any other fabric. The aesthetic one: the natural light-reflecting quality of Grade 6A mulberry silk charmeuse elevates the look of a sofa, bed or reading chair in a way no synthetic can replicate. Customers who buy one Jass London cushion cover almost always return for more – not because the first wore out, but because they want the look throughout the room.
