100% Mulberry Silk Pillowcase King Size 20x36 in - Cooling Beauty Case

In this review the SUNDAYSILKS 100% Mulberry Silk Pillowcase in king size 20x36 in stands out as a clear pick for sleepers who prioritize skin and hair health. The bottom line: it is for anyone who wants a truly soft, cooling pillow cover that reduces friction on hair and prevents creases on the face. The reviewer found the fabric noticeably smoother than typical satin alternatives and appreciated the hidden zipper that keeps the cover in place, making it a practical nightly upgrade rather than just a decorative piece.

Key Features

• 100% Mulberry Silk: The natural silk fibres offer a luxuriously soft surface that reduces hair breakage and minimizes sleep lines on the skin.
• King Size 20x36 in: The larger dimensions suit deep or oversized pillows and keep the fabric from pulling tight at the corners.
• Hidden Zipper Closure: A discreet zipper secures the pillow inside the case and helps the cover stay put throughout the night.
• Sustainably Certified: The pillowcase is OEKO-TEX certified, indicating reduced chemical exposure and attention to sustainable sourcing.
• Cooling Weave: The advanced silk weave feels cool to the touch, which can benefit hot sleepers seeking more comfortable nights.
• Amino Acid Infusion: The silk is described as containing 18 amino acids to support hair and skin health while you sleep.

Who It's For

This pillowcase is ideal for people concerned with hair frizz, split ends and facial creases who want a nightly, low-effort beauty boost. Hot sleepers and those who prefer a cooler fabric against the face will like the silk weave that sleeps noticeably cooler than cotton or many synthetics.

Those on a tight budget or shoppers who need a wrinkle-resistant, machine-tough textile for heavy daily washing may want to compare alternatives, since delicate silk requires gentler care and some users report wear around seams after repeated laundering.
