California King Deep Pocket Sheet Set - Cooling, Fits 21in Mattresses

Our review of these California king deep pocket sheet sets finds them best for hot sleepers and anyone with a tall mattress or topper. The single biggest reason to buy is the combination of moisture wicking performance and a secure fit: the sheets use 3M Scotchgard enhanced moisture-wicking treatment to pull sweat away from the skin while a full elastic, deep pocket fitted sheet stays put on mattresses up to 21in thick. For sleepers who value consistent coolness and hotel-like softness without constant readjusting, these sheets deliver reliable daily comfort.

Key Features

• Moisture wicking: 3M Scotchgard enhanced treatment helps move sweat away so hot sleepers stay drier and cooler through the night.
• Deep pocket fit: The fitted sheet has full elastic and an extra deep pocket designed to fit mattresses and toppers up to 21in thick without slipping.
• Durable brushed fabric: Premium brushed 100% polyester fabric provides lasting softness and resists wear from regular use and washing.
• Classic pintuck design: Pintuck edges on the pillowcases and top sheet add a textured, dimensional look that elevates bedroom style.
• Complete four-piece set: Includes one flat sheet, one fitted sheet and two pillowcases sized for California king beds for simple setup.

Who It's For

This set is aimed at people with deep or pillow-top California king mattresses, and sleepers who tend to overheat overnight. The combination of deep pockets and moisture-wicking fabric makes it a practical choice for restless sleepers who need sheets that both stay in place and manage dampness.

Those who prefer natural fibers like cotton or linen, or who want an ultra-breathable percale weave, should look elsewhere. Also, shoppers seeking fitted sheet options for nonstandard mattress dimensions or specialty fabrics should verify fit and material preferences before purchasing.
