King Size Bamboo Viscose Fitted Sheet 18in Deep Pocket - White

In this review the king size Bella Coterie fitted sheet is examined for hot sleepers and anyone after a luxury, cooling option that also fits deep mattresses. The bottom line: this 100% viscose made from bamboo fitted sheet stands out for its silky feel and moisture-wicking performance, making it the single best pick for people who prioritize softness and temperature regulation. Our review finds it especially useful for plush pillow-top beds thanks to the 18in deep pocket and consistently praised for durable comfort after repeated washes.

Key Features

• 100% Viscose from Bamboo: Provides a lightweight, silky surface that feels like premium bedding and becomes softer with each wash.
• Cooling and Moisture-Wicking: Hypoallergenic and breathable fabric helps hot sleepers stay cooler through the night by moving moisture away from skin.
• 400 Thread Count Quality: A higher thread count construction that delivers a smooth, substantial hand without feeling heavy.
• 18in Deep Pocket Fit: Extra deep pocket design accommodates thick pillow-top and plush mattresses without pulling off.
• OEKO-TEX 100 Certified: Tested free of more than 100 harmful chemicals so you can sleep on bedding with safer textile standards.
• Machine Washable Durability: Maintains softness and color through normal washing, making it practical for everyday use.

Who It's For

The Bella Coterie king fitted sheet is ideal for hot sleepers, couples who value a silky, smooth feel, and owners of deep pillow-top mattresses who need an 18in pocket. It particularly suits shoppers looking for hypoallergenic and sustainably minded textiles because the viscose derived from bamboo is lightweight and OEKO-TEX 100 certified.

Shoppers who prefer crisp, percale-cotton texture or need fitted sheets in non-standard mattress depths under about 18in should look elsewhere. Those wanting a full sheet set rather than a single fitted piece may prefer to purchase coordinated sets from other lines.
