California King Cooling Sheet Set - Soft Rayon Blend Spa Blue

In this review of the California King sheet set, the bottom line is simple: these are for sleepers who want a very soft, cooling-feeling sheet at an affordable price. The set stands out for its blend of 60% rayon derived from bamboo and 40% microfiber that creates a silky, smooth surface and a noticeably cool touch. While not traditional silk, the fabric is durable and machine washable, making it a practical choice for people who sweat at night or who prefer a softer-than-cotton hotel-style sheet.

Key Features

• Material blend: The 60% rayon derived from bamboo and 40% microfiber twill weave provides a smooth, silk-like feel while remaining stronger than typical cotton.
• Cooling performance: The fabric is designed to adjust temperature and absorb moisture, helping hot sleepers feel cooler and drier through the night.
• Deep pockets: The fitted sheet fits mattresses up to 16' deep and grips well, reducing slipping when you move in bed.
• Set contents: The Cal King four-piece set includes one flat sheet 108' x 102', one fitted sheet 72' x 84' x 16' and two pillowcases 20' x 40', offering full coverage for a Cal King bed.
• Care and durability: Unlike delicate silk, these sheets are machine washable on gentle and dryable at low temperature for everyday use.
• Safety certification: The fabric is Standard 100 by OEKO-TEX certified, indicating it has been tested for harmful substances.

Who It's For

These sheets are best for hot sleepers, people who prefer a silky, hotel-like texture, and anyone seeking an affordable upgrade from basic cotton without fragile laundry needs. The cooling and moisture-wicking characteristics make them a sensible pick for those who experience night sweats.

Shoppers who want crisp, heavyweight percale or those expecting a pure bamboo or pure natural fiber may want to look elsewhere; some customers note the feel and thickness lean toward microfiber rather than a wholly bamboo experience.
