Split Top King Size Bamboo Viscose Sheet Set - Grey Mist

In this review we look at the Bella Coterie split top king size sheet set in Grey Mist and why it stands out for sleepers who need both depth and temperature control. The bottom line: this set is best for hot sleepers with deep, plush mattresses who want a silky, lightweight feel - the 34in split and 18in deep pocket solve fit issues while the viscose made from bamboo fabric delivers a cooling, hypoallergenic surface that gets softer with every wash.

Key Features

• 100% Viscose from Bamboo: Provides a silky, breathable surface that helps regulate temperature so sleepers report feeling cool rather than overheated.
• 34in Split Top Design: The split top fitted sheet makes it easy to get in and out of bed and ideal for adjustable bed bases or couples who want independent access.
• 18in Extra Deep Pocket: Fits very plush pillow top mattresses without slipping off, keeping the fitted sheet taut through the night.
• 400 Thread Count Feel: A dense, smooth weave that softens with each wash and balances durability with a lightweight hand.
• OEKO-TEX 100 Certified: Tested to be free of over 100 harmful chemicals, offering reassurance for sensitive skin and health-conscious buyers.
• Moisture-Wicking and Hypoallergenic: Designed to move moisture away from the skin and minimize irritants for a more comfortable sleep experience.

Who It's For

This sheet set is ideal for hot sleepers, couples using adjustable beds, and owners of deep pillow top mattresses who need an 18in pocket and the convenience of a 34in split top. The silky viscose fabric also suits people with sensitive skin or those seeking a lightweight, breathable sheet that performs across seasons.

Shoppers looking for ultra wrinkle-resistant cotton-like crispness or those who prefer crisp percale over a soft, silky hand may want to consider other fabrics. Also, buyers who prioritize long-term proven durability over initial softness should note that customer opinions on longevity are mixed.

Pros & Cons

Cons

• Wrinkle resistance is limited compared with crisp cotton percale, so sheets may appear less smooth after washing.
