Product Features

100% Mulberry Silk Construction - Made from 19 momme, 7A+ grade mulberry silk. This is a high thread density of 400. Higher momme weight means thicker, more durable silk. The natural protein fibres contain 18 amino acids that work in harmony with skin, reducing irritation during sleep. Temperature Regulation - Silk fibres naturally adjust to body heat, keeping you cool in summer and warm in winter. This works well for people who wake up sweating or feeling cold at night. The breathable structure moves moisture away from skin rather than trapping it. Deep Pocket Fitted Sheet - The fitted sheet holds mattresses up to 16 inches deep, including the 76cm x 203cm base. This fits most modern mattresses with toppers or extra padding, so the sheet stays in place without slipping off corners during the night.

OEKO-TEX Standard 100 Certification - This certification confirms the fabric has been tested for harmful substances. It means no chemical ingredients were used in production. For people with sensitive skin or allergies, this certification gives peace of mind about what touches their body each night. Envelope Design Pillow Shams - The two pillow shams measure 20 x 36 inches plus a 2 inch flap, using an envelope opening. This makes it simple to insert and remove pillows without wrestling with zips or buttons. The pressed edge style gives a neat finished look. Low Friction Surface - Silk creates less friction against hair and skin compared to cotton. This can reduce hair breakage and frizz caused by rubbing against a pillowcase overnight. Many people notice softer hair and fewer sleep creases on their skin after use.

FAQs

What size mattress does this fitted sheet fit?

The fitted sheet measures 76 x 80 inches (approximately 193cm x 203cm) with a 16 inch pocket depth. This fits King size mattresses, including those with a mattress topper or extra depth, up to around 40cm thick.

Is this silk sheet set suitable for people with allergies?

Yes. The set is OEKO-TEX Standard 100 certified, meaning it has been tested and contains no harmful chemicals. Mulberry silk is naturally hypoallergenic and resists dust mites, making it a good choice for people with sensitive skin or allergies.

How do I wash this silk sheet set?

THXSILK recommends hand washing or machine washing on a gentle cycle in warm water at 30°C. Use a neutral, mild detergent to prevent colour fading. Avoid direct sunlight when drying to protect the fibres and colour.

What is 19 momme and why does it matter?

Momme is a unit that measures silk density and weight. 19 momme is considered a mid-to-high weight for bedding, offering good durability while remaining soft. Higher momme silk tends to last longer and feels more substantial than lower momme alternatives.

Does silk bedding actually help with hair and skin?

Silk has a smoother surface than cotton, which creates less friction as you move during sleep. This can reduce hair breakage, frizz and tangling. For skin, less friction may mean fewer sleep creases and less pulling on delicate facial skin overnight.

What pieces come in this set?

The King set includes one duvet cover (102" x 90.5"), one fitted sheet (76" x 80" with 16" pocket depth) and two pillow shams (20" x 36" plus a 2" flap). The duvet cover closes with a zipper.

Is this silk set suitable for all seasons?

Yes. Mulberry silk naturally regulates temperature, so it feels cool against skin in warm weather and retains warmth in cooler months. This makes it a practical choice for year-round use rather than swapping bedding by season.

What colour options does this specific set come in?

This listing is for the charcoal colourway, a solid dark grey shade. The set has a plain, solid pattern throughout all four pieces, giving a clean and coordinated look on the bed.
