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

In this review of the King size Bella Coterie fitted sheet the bottom line is simple: this is for sleepers who want a luxurious, cooling sheet that fits very deep mattresses. The reviewer found the 100% viscose from bamboo fabric immediately soft and noticeably silky to the touch, and its moisture-wicking properties made nights feel cooler. With an 18in extra deep pocket and a 400 thread count feel, this fitted sheet is best for those with plush pillow top mattresses or anyone who prioritizes a soft, breathable fabric; its OEKO-TEX 100 certification is an added reassurance.

Key Features

• 100% Bamboo Viscose: Provides a lightweight, silky feel that is hypoallergenic and cool to the touch for hot sleepers.
• 400 Thread Count Feel: Delivers a smooth, dense surface that becomes softer with each wash while retaining a premium hand feel.
• 18in Deep Pocket: Ensures a secure fit on thick pillow top mattresses and keeps the sheet tucked without constant readjustment.
• OEKO-TEX 100 Certified: Tested free of over 100 harmful chemicals so you can sleep on bedding with greater peace of mind.
• Moisture-Wicking Performance: Moves perspiration away from skin for a drier, more comfortable night when temperatures rise.

Who It's For

This sheet is ideal for couples and solo sleepers who need a deep-pocket fitted sheet for mattress depths up to 18in and who prefer a silky, cooling fabric. It suits people who value hypoallergenic, chemical-tested bedding and those who want sheets that soften with washing rather than becoming crisp or rough.

It may not be the top choice for shoppers who prefer heavier, high-structure cotton percale or those seeking a full sheet set rather than a single fitted sheet; shoppers wanting crisp, very matte finishes should look at different materials.

Pros & Cons

Pros

• Very soft, silky fabric that customers report becomes even softer after washes.
• Generous 18in pocket fits thick mattresses and holds well in place.
• Cooling and moisture-wicking properties good for warm sleepers.
• OEKO-TEX 100 certification offers reassurance about chemical safety.

Cons

• As a viscose fabric it has a drapey, silky hand that may not satisfy those wanting crisp percale texture.
• Only the fitted sheet is covered here, so matching flat sheets or pillowcases must be purchased separately if needed.
