California King Bamboo Sheets - Soft Cooling 100% Viscose

Our review finds these California King sheets best for sleepers who want a silky, naturally cooling set made from pure viscose derived from bamboo. The single biggest reason to buy is the genuine 100% organically grown viscose fabric that delivers resort-grade softness and moisture-wicking cooling without blends; it feels like silk and gets softer with washing while offering OEKO-TEX Standard 100 safety testing. For anyone seeking a deep-fit, long-lasting sheet set with a luxury sateen feel, these sheets are a strong contender.

Key Features

• 100% Viscose Derived from Bamboo: Provides a sensuous, silky handle and becomes softer with each wash while remaining free from blended fibers.
• Complete 4-Piece Set: Includes a fitted sheet, flat sheet and two envelope-style pillowcases with overlapping closures for a neat, secure fit.
• Cooling and Breathable: Naturally thermo-regulating and moisture-wicking, making these sheets a good choice for hot sleepers or warm nights.
• Deep Fitted Pockets: Fully elasticized fitted sheet fits mattresses up to 16 in thick for a snug, no-slip fit.
• 300 Thread Count Sateen: Sateen weave provides a silky smooth surface while balancing softness and pilling resistance compared with ultra high thread counts.

Who It's For

These sheets suit people who prioritize a silky, cooling sleep surface and prefer bedding made from a single, naturally derived fiber. They are especially well suited to hot sleepers, those with sensitive skin looking for OEKO-TEX tested fabric, and owners of deep mattresses who need generous pocket depth and a secure elasticized fit.

Shoppers seeking crisp, cotton-style sheets with a matte finish or those who expect perfect wrinkle resistance may want to consider other materials; opinions on wrinkles are mixed. Also, buyers who prefer blended-performance fabrics for extra stretch should note these are pure viscose, not mixed with other fibers.
