California Design Den XL Twin Sheets Set – 600TC 100% Cotton Sateen, All-Around Elastic, White

Elevate your sleep with the California Design Den XL Twin Sheets Set

Discover a refined blend of comfort and durability in a white twin XL sheet set crafted from 100% long-staple cotton. The 600 thread count is realized through a single-ply construction that delivers a balanced feel: plush enough to feel luxurious, yet light enough to breathe with you through the night. A subtle, luminous sheen catches the light, signaling quality without sacrificing everyday practicality. Independently verified by labs, this set also earned recognition from a leading home care authority, underscoring its thoughtful design.

The practical design supports real-life routines, from late-night study sessions to early-morning rises. The smooth surface feels naturally breathable and gentle on skin, making it appealing for year-round use. The white shade provides a timeless backdrop for any bedroom style, and the fabric’s durability means you can expect softness to persist after repeated washes.

What’s included and how it fits your bed

• 3-piece Twin XL set: 1 flat sheet, 1 deep-pocket fitted sheet with all-around elastic that fits mattresses 8–15 inches deep, and 1 standard pillowcase. Flat sheet measures 66" W x 100" L; Fitted sheet 39" W x 80" L; Pillowcase 21" W x 32" L.
• Deep-pocket fit and elastic edge: keeps the sheet snug through the night, helping to reduce wrinkles and shifting.

Built for longevity and easy care

• OEKO-TEX STANDARD 100 certified, independently tested for safety and harmful substances.
• Durable long-staple cotton with a thread count that remains true within a small tested range (+/-5%).
• Fabric tested to resist pilling, fading, and shrinkage; machine wash warm and tumble dry low for best results.
• Visibly smooth finish that softens with every wash, while maintaining structure for a crisp, tidy bed.

Beyond the fabric itself, the California Design Den brand emphasizes transparency and responsibility. Since 2017, the company has prioritized quality and ethical production, partnering with a family-run factory in India. The brand’s commitment is reflected in charitable efforts totaling thousands of sheet sets donated across the U.S., a testament to its focus on comfortable sleep for more people.
