Coastal Blue Bamboo Viscose King Sheet Set - Cooling 18in Pocket

In this review the Coastal Blue Bella Coterie king sheet set stands out as a strong option for hot sleepers who also want a luxurious feel. The single biggest reason to buy is the 100% viscose made from bamboo fabric, which reviewers repeatedly praise for feeling like cool silk against the skin and for reliable temperature regulation. Lightweight, hypoallergenic and moisture-wicking, this set aims to keep sleepers comfortable year-round while the 18in deep pocket fitted sheet accommodates thick, plush mattresses.

Key Features

• 100% Viscose from Bamboo: Feels silky and smooth on contact, delivering a cool sensation that many customers describe as like cool silk on the skin.
• 400 Thread Count: Offers a dense, soft weave that tends to get softer with each wash and delivers a premium tactile experience.
• 18in Deep Pocket: The extra deep fitted sheet fits high-profile and pillow-top mattresses without slipping off during the night.
• OEKO-TEX 100 Certified: Tested free of over 100 harmful chemicals, providing peace of mind for sensitive skin and health-conscious shoppers.
• Thermoregulating and Moisture-Wicking: Lightweight construction helps dissipate heat and wick moisture, useful for warm sleepers or humid climates.

Who It's For

The Coastal Blue king sheet set is best for sleepers who prioritize softness and cooling performance, especially those who run hot at night or who prefer a silky, drapey feel instead of crisp cotton. It is also a good match for households seeking hypoallergenic bedding and chemical-free certification.

Shoppers who need exceptionally high durability over many years or wrinkle-resistant performance should compare options; some customers report mixed durability impressions and the fabric naturally shows softer, more relaxed drape rather than a pressed, wrinkle-free finish.

Pros & Cons

Pros

• OEKO-TEX 100 certification reduces concerns about harmful chemical residues.

Cons

• Durability reports are mixed among customers, so long-term wear may vary depending on care.
