California Design Den Twin XL Deep Pocket Fitted Sheet - Soft 400 TC

In this review of the California Design Den Twin XL deep pocket fitted sheet, the bottom line is clear: college students and anyone with a taller mattress will appreciate the snug fit and breathable 100% cotton sateen. The reviewer found the sheet to be noticeably soft out of the package and to become even softer after washing, while the all-around elastic and generous depth keep it securely in place on mattresses up to 15 in deep. This single fitted sheet delivers cooling comfort and durable construction without extra pieces or frills.

Key Features

• Deep Pockets: The 15 in deep pocket design fits both low foam and taller mattresses and prevents popping off during the night.
• 100% Cotton Sateen: Long-staple Indian cotton gives a smooth, soft hand feel that becomes softer with each wash.
• 400 Thread Count: A balanced weight that produces a soft, breathable fabric with a subtle sheen and durable weave.
• All-Around Elastic: Premium elastic around the hem keeps the fitted sheet snug, reducing bunching and shifting on dorm beds.
• Certified Safe: Independently tested and Standard 100 by Oeko-Tex certified, indicating the fabric is free from harmful substances.
• Low Maintenance: Machine washable and designed to resist shrinking, pilling, and fading for easier care in shared living spaces.

Who It's For

The fitted sheet is ideal for students heading to dorms, anyone using a Twin XL mattress, and people who prefer natural, breathable bedding over synthetic alternatives. Its deep pockets and all-around elastic make it especially suitable for beds with mattress toppers or foam layers up to 15 in deep.

Those who need a full sheet set with pillowcases or prefer a very crisp percale finish should look elsewhere; this listing is a single fitted sheet in a soft sateen weave and not part of a packaged set. Also, shoppers seeking a bright, vivid blue should note this color is a gentle, muted pale blue rather than a bold or baby blue.
