SmartSilk Collection for Kingsdown

SmartSilk Collection for Kingsdown - 100% Silk Lined Mattress Protector


Fits mattresses up to 17" thick

The SmartSilk™ Collection for Kingsdown 5 Sided Mattress Protector combines an all-natural silk liner with an all-natural soft cotton finish to provide you with a mattress cover that’s as cozy as it is effective. This breathable mattress protector is Certified Asthma & Allergy Friendly™ by the Asthma and Allergy Foundation of America and Asthma Canada for a healthier and cleaner night's sleep. 

Backed by The SmartSilk™ Shield Advantage—a proven barrier against allergens, dust mites and pet dander—you can finally get the quality sleep that you deserve.


Breathable 100% Cotton Quilted Outer Shell, Lined with 100% Pure Silk

Cotton is one of nature’s most breathable materials. Soft to the touch, it provides the perfect comfort in every season.

Temperature Regulating

Our mattress protector is designed to naturally regulate your body temperature, even when you’re under the covers.


SmartSilk™ hypoallergenic bedding is chemical free, resistant to mold and mildew, and provides a natural barrier to reduce your exposure to allergens.

Moisture Wicking

Silk is naturally non-absorbent and keeps moisture on the outside surface where it quickly evaporates.


Our breathable material keeps you cooler and more comfortable throughout the night.

Machine Washable

SmartSilk™ products have been tested and proven to be machine washable in cold water and can be dried at home at low temperatures. Use the delicate cycle to wash and a small amount of detergent for delicate fabrics.
