California Design Den King Duvet Cover — Indigo Dusty Blue, 400‑Thread Cotton Sateen, OEKO‑TEX

California Design Den’s Luxury Indigo Dusty Blue King Duvet Cover is a 400-thread-count cotton sateen cover designed to protect your comforter while giving your bedroom a calm, modern indigo tone.

This king duvet cover blends breathable, soft cotton with a refined indigo dusty blue shade—subtle grey undertones, no purple or deep navy—so it coordinates easily with linens and décor. The cover is sold separate from the comforter (one duvet cover, 106" W x 90" L) and features practical details to secure your insert and make laundering simple. It carries OEKO-TEX STANDARD 100 certification and the Good Housekeeping Seal, reflecting quality testing and award recognition.

How will this duvet cover change the look and feel of my bedroom?

The indigo dusty blue provides a serene, contemporary palette that pairs with neutrals and richer accent colors. The sateen weave adds a subtle sheen for a cleaner, elevated appearance without feeling glossy.

• Refined indigo with soft gray undertones for modern calm
• Sateen finish offers a smooth hand and soft luster
• Matches the brand’s sheet and pillowcase sets for coordinated styling

What features keep my duvet insert secure and easy to care for?

This cover is built with user-friendly fastenings and internal ties to stabilize the insert, so you won’t wake to a shifted comforter. Cotton sateen is machine washable and dries on regular settings, making upkeep straightforward.

• Button closures along the base for a neat finish
• Four internal ties anchor your insert and reduce movement
• Durable, colorfast fabric resists fading in normal home laundering

Is this duvet cover safe, high-quality, and ethically made?

• OEKO-TEX STANDARD 100 certification for tested textiles
• Awarded the Good Housekeeping Seal and GH Best Bedding recognition
• Family-owned manufacturing with quality checks and sustainable packaging efforts

What size is the king duvet cover and will it fit my comforter?

The cover measures 106" wide by 90" long — a common king size intended to fit most standard king comforters. Measure your insert before ordering to ensure the best fit and loft when zipped inside.

• Dimensions: 106" W x 90" L (king size)
• Sold as cover only; insert/comforter not included

Who this is for: This duvet cover is intended for sleepers who want a breathable, soft cotton cover with a modern indigo hue and practical construction.
