California Design Den 840307131003 Cotton Sheet Set, 600 Thread Count, California King

Bedding shoppers often choose between a crisp, lightweight feel and a smoother, more substantial finish. This California King set brings together long-staple cotton and a 600-thread-count sateen weave for a soft hand and subtle sheen.

Its Dusty Navy Blue solid color adds a composed look to the bed, while the cotton fabric is naturally breathable for year-round use. The set is made for one California King mattress, with a fitted sheet designed for mattresses 8 to 16 inches deep.

The four-piece set includes a flat sheet, fitted sheet, and two king-size pillowcases. All pieces are machine washable and can be tumble dried.

Practical tips

Use the fitted sheet’s all-around elastic to secure it around the mattress, then use the head-and-foot indicator tags to orient it while making the bed. Its 16-inch pocket accommodates mattresses from 8 to 16 inches deep. This set is sized for a standard California King mattress, not a split King.

The finished flat sheet measures 108 by 106 inches, and the fitted sheet measures 72 by 84 inches. Each pillowcase measures 21 by 40 inches and has an open-end design. These dimensions help you match the set to your bed and pillow arrangement before making the switch.

For routine care, machine wash warm and tumble dry low. Removing the sheets promptly after drying can help reduce wrinkles. The fabric has also been tested for shrinkage, pilling, and fading.

Why it makes sense

The 100% long-staple cotton sateen combines a smooth feel with a structured weight and breathable construction. That makes the set a practical fit for sleepers who want the polished look of a subtle sheen without giving up cotton’s airy feel. The fabric is designed to become softer with washing, and the Good Housekeeping Seal adds a recognized point of reference when choosing bedding.

The set is OEKO-TEX STANDARD 100 certified, and its solid Dusty Navy Blue finish makes it easy to coordinate with a range of bedroom styles. Rather than buying pieces separately, you get a fitted sheet, flat sheet, and matching pillowcases in one coordinated California King set.

Buyer feedback often praises the softness, comfort, appearance, and fit, especially on deeper mattresses. Some customers say the sheets soften with washing, while opinions on long-term durability and wrinkle resistance vary. These are individual experiences, so care and laundering remain useful parts of getting the most from cotton bedding.

Key takeaways

This is a 600-thread-count, 100% long-staple cotton sheet set with a sateen weave, a smooth feel, and a subtle lustrous finish. The fitted sheet’s all-around elastic and 16-inch pocket are useful details for a secure fit on compatible California King mattresses. The four pieces coordinate in a solid Dusty Navy Blue color, and the set is machine washable for straightforward regular care.
