California King Deep Pocket Sheet Set - Soft Breathable 1800 TC

Our review of the HYPREST California King sheet set finds it best for sleepers who need deep pockets and a soft, low-maintenance sheet they can use year-round. The biggest reason to buy is the combination of a true deep-pocket fitted sheet that fits mattresses up to 18' in and a lightweight, breathable microfiber weave that stays soft with washing. The set feels gentle against skin, resists obvious wrinkling, and keeps tuck-in security without frequent adjustments, which makes it a practical choice for busy households and thicker mattresses.

Key Features

• Deep pocket fitted sheet: The fitted sheet stretches to fit mattresses up to 18' deep so it stays in place on thick or pillow-top beds.
• Complete king set: Includes one flat sheet (108'x102'), one fitted sheet (78'x80') and two 20'x40' pillowcases, providing full bed coverage for California king beds.
• Soft microfiber fabric: Made from 100% microfiber, the sheets are soft to the touch and tend to get softer after each wash while maintaining a smooth feel.
• Breathable and moisture-wicking: The lightweight weave helps regulate temperature and wicks moisture for comfortable year-round use.
• OEKO-TEX certified: Manufactured under the Standard 100 by OEKO-TEX, indicating independent testing and adherence to textile safety standards.
• Easy care: Machine washable on a gentle cycle and tumble dry low, with fine stitching for durability and low maintenance.

Who It's For

This sheet set is ideal for owners of California king beds who need a reliable deep pocket sheet that will not slip off taller mattresses and for people who prefer a soft, lightweight microfiber that breathes. It is also a good match for couples or restless sleepers who want sheets that remain tucked under movement.

Shoppers who prefer heavier cotton percale, natural fibers like linen, or a plush, thicker feel may want to look elsewhere. If you prioritize a crisp, cool-to-the-touch natural fabric or want very thick hotel-style sheets, microfiber may not meet those specific expectations.
