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

In this review the SUNDAYSILKS 100% Mulberry Silk Pillowcase (king size 20x36 in) is assessed for anyone who wants a nightly beauty upgrade that also sleeps cooler. The bottom line: this pillowcase is for people who prioritize skin and hair health and prefer a luxurious, satin-smooth sleep surface. The single biggest reason to buy is its genuine mulberry silk construction, which delivers an unmistakably soft feel and the anti-crease, anti-acne and anti-frizz benefits silk is known for, while a hidden zipper keeps the pillow tucked in place.

Key Features

• 100% Mulberry Silk: The natural silk fibers create a satiny surface that is gentle on hair and skin and reduces friction overnight.
• King Size 20x36 in: The larger dimensions fit standard king pillows and offer full coverage for head and hair throughout sleep.
• Hidden Zipper Closure: A zipper keeps the pillowcase securely on the pillow so it does not slip off during the night.
• Cooling Weave: The advanced silk weave helps hot sleepers stay cooler and improves overall sleep comfort.
• Beauty Benefits: The silk is described as infused with amino acids to support anti-aging, anti-crease and anti-acne outcomes for skin and hair health.
• OEKO-TEX Certified: The silk is sustainably sourced and certified for low chemical content, appealing to conscious buyers.

Who It's For

The SUNDAYSILKS king pillowcase is best for sleepers who want a premium bedding upgrade focused on beauty and comfort; people with frizzy hair, fine facial skin, or those who wake with creases will notice the benefits of the silk surface. It also suits hot sleepers who prefer a fabric that feels cool to the touch and stays smooth against the skin.

Shoppers who need heavy-duty, high-abuse bedding or who prefer extremely low-cost options may want to look elsewhere, and anyone who is concerned about careful laundering should note silk requires more delicate care than cotton blends to maintain longevity.
