Split Top King Size Bamboo Viscose Sheet Set Slate Blue - 18in Deep

In this review the Bella Coterie split top king size sheet set is evaluated for hot sleepers and owners of deep pillow top mattresses; the bottom line is that these sheets are best for anyone who wants a silky, cooling bedcover that fits up to 18in mattress depths. The reviewer found the fabric noticeably smooth and lightweight, praised its moisture-wicking feel, and observed that the 34in split on the top fitted section makes standing transfers and accessibility easier for couples or medical-style beds. Overall the set reads like a luxury everyday option that balances comfort and practical fit.

Key Features

• 100% Viscose from Bamboo: Provides a silky, breathable surface that helps regulate temperature and feels cool to the touch for hot sleepers.
• 400 Thread Count Feel: Offers a soft, substantial hand that becomes even softer after repeated washes without feeling heavy.
• 18in Deep Pocket Fitted Sheet: Designed to fit deep pillow top mattresses and stay secure through movement and nightly use.
• 34in Split Top Design: The split at the top allows easier entry and exit for shared beds where one side may need different access or bedding control.
• OEKO-TEX 100 Certified: Tested free of over 100 harmful chemicals, which gives peace of mind for sensitive skin and allergy-prone sleepers.
• Moisture-Wicking and Hypoallergenic: Lightweight construction helps move moisture away from the skin while remaining gentle for sensitive users.

Who It's For

These sheets are ideal for hot sleepers looking for a breathable, silky option that also fits very deep mattresses; couples who need a split top for easier bed access will appreciate the 34in split. People who prefer natural-derived fibers and care about chemical testing will value the OEKO-TEX certification and the bamboo-derived viscose construction.

Those who want total wrinkle resistance or expect cotton-like crispness should look elsewhere, and buyers seeking heavyweight, thermal winter bedding will find these too lightweight. Budget shoppers who prioritize long-term durability over initial softness may want to compare other options, since customer feedback on longevity is mixed.
