These California Design Den Twin XL sheets are a 3-piece set made from 100% cotton sateen, delivering a soft, breathable, naturally luminous sleeping surface that fits mattresses up to 12".

Designed for everyday comfort, this Bright White Twin XL collection blends the crispness of fresh cotton with a subtle sateen sheen. The set includes a fitted sheet with all-around elastic, a roomy flat sheet, and an envelope-style pillowcase—each piece crafted to soften with repeated washing while maintaining durability. Independently tested and honored with the Good Housekeeping Seal, these sheets balance natural fiber performance with easy-care practicality.

How will these sheets feel on the bed?

The cotton sateen weave gives a smooth, slightly lustrous hand that begins with a fresh, crisp feel and becomes softer over time. Air channels in the natural cotton fibers help maintain breathability so you stay comfortable through different seasons.

• Sateen weave for a silky, smooth surface and subtle sheen.
• Starts crisp and softens with regular laundering.
• Lightweight cotton for balanced warmth and airflow.

Do these sheets fit my Twin XL mattress and stay in place?

The set is sized specifically for Twin XL beds and the fitted sheet includes all-around elastic to reduce slipping and bunching. The elastic is designed to accommodate mattresses up to 12" deep so the sheet tucks snugly and stays secure.

• Fitted sheet dimensions: 39" W x 80" L, fits up to 12" mattress depth.
• All-around elastic for consistent hold without exposed corners.
• Top/bottom tags simplify correct placement when making the bed.

How do I care for and maintain the cotton sateen fabric?

Care is straightforward: machine wash warm and tumble dry low, then remove promptly to minimize wrinkles. Expect a noticeable softening after the first few wash cycles; avoid judging texture immediately from the dryer—cotton relaxes and feels softer once cooled.

• Machine wash warm; tumble dry low and remove promptly.
• Fabric tested for pilling, tearing, fading, and shrinkage.
• Becomes more comfortable with each wash, similar to favored denim.
