California Design Den 840307131065 California King Sheet Set, 600 TC Cotton Sateen

For a California king bed, this four-piece sheet set pairs a smooth cotton sateen feel with a fitted sheet designed for mattresses 8–16 inches deep. Its muted sage green shade adds a soft, cool-toned accent to the bedroom.

The fabric is made from 100% long-staple cotton with a 600 thread count. A sateen weave gives it a smooth hand and subtle sheen, while the cotton is naturally breathable for comfortable use throughout the year.

Choose this set if you prefer a silky-smooth surface and gentle luster over a more matte, crisp-feeling sheet style. The color has subtle blue undertones, for a calm seafoam look rather than a bright green or teal.

Everyday use

The set is made for one California king mattress and includes a flat sheet, a fitted sheet, and two king pillowcases. The fitted sheet measures 72 x 84 inches and has all-around elastic to hold it in place, its deep pocket fits mattresses 8–16 inches deep. Top and bottom indicator tags make it easier to orient the fitted sheet when making the bed.

The flat sheet measures 108 x 106 inches, and each open-end pillowcase measures 21 x 40 inches. The open-end design keeps the cases simple to use, while the coordinated solid sage green gives the bed a consistent look. This is a California king set for one mattress, not a split king set.

For care, machine wash warm and tumble dry low. Removing the sheets promptly from the dryer can help reduce wrinkles. The cotton sateen is tested for shrinkage, pilling, and fading, making straightforward machine care part of its everyday appeal.

Strengths

Long-staple cotton and a 600 thread count give the fabric a substantial, structured feel, while the sateen weave brings a smooth finish and soft sheen. The combination suits shoppers who want bed linens with a refined look and a comfortable hand without giving up the breathability associated with cotton. The fabric is described as becoming softer after washing, and its breathable feel supports use across the seasons.

The set carries the Good Housekeeping Seal and OEKO-TEX Standard 100 certification. It is also identified as a 2026 Oprah Daily Sleep Award winner. These documented distinctions add useful context for shoppers comparing cotton sheet sets, alongside practical details like the deep pocket, all-around elastic, and orientation tags.

What matters most

The fit is the key choice: this set is sized for a California king mattress, with a fitted-sheet pocket depth suited to mattresses from 8 to 16 inches. Matching the mattress size and depth to those measurements helps you choose a set designed for the bed you are making. The four-piece arrangement supplies the core layers—flat sheet, fitted sheet, and two pillowcases—in one coordinated set.

The fabric and color help narrow the decision further. Choose the cotton sateen if a smooth, subtly lustrous surface is your priority, a matte, crisper-feeling sheet style may better match a different preference. Sage green with cool, blue-toned undertones works well when you want a muted color rather than a vivid accent. Together, the California king sizing, 100% cotton construction, and easy-care instructions make the set practical for a regularly used bed.

Final verdict

This California king sheet set is a strong fit for shoppers who want long-staple cotton, a smooth 600-thread-count sateen weave, and a deep-pocket fitted sheet in one coordinated package. Its cool sage color brings a restrained touch of color, while the measured fit details and machine-wash care help make it an easy choice for updating an everyday California king bed.
