California Design Den Twin XL Cotton Sateen Sheet Set, Pink — 3-Piece 400TC Deep-Pocket

Soft 100% long-staple cotton Twin XL sheets in pink — a 3-piece set with a 400 thread-count sateen weave, deep-pocket fitted sheet, and a breathable lightweight feel.

These California Design Den Twin XL sheets combine a smooth cotton-sateen hand with durable everyday performance. Independently tested and recognized with the 2026 Good Housekeeping Best Bedding Award, the set is sized for extra-long twin mattresses and arrives in recyclable, plastic-free packaging. The fabric is single-ply long-staple cotton with a verified 400 thread count and a finish that becomes softer over repeated washes.

What pieces come in this Twin XL set and what are their finished sizes?

The set contains three essential pieces designed for an extra-long twin mattress: a flat sheet, a deep-pocket fitted sheet, and a standard pillowcase. Tags on the top/bottom edges help make bed-making quick and accurate.

• Flat sheet: 66" W x 100" L — generous length for bed tuck and layering.
• Fitted sheet: 39" W x 80" L — fits mattresses 8"–15" deep with all-around elastic.
• Pillowcase: 21" W x 30" L — standard open-end style for easy pillow insertion.

How does the fabric feel and perform after washing?

The single-ply long-staple cotton woven in a sateen finish offers a smooth, slightly lustrous surface that softens with each wash without losing structure. It’s been tested for pilling, fading, and shrinkage to hold up to regular home laundering.

• Lightweight, breathable cotton keeps the sheets comfortable across seasons.
• Softens over time like favorite denim while maintaining strength.
• Machine wash warm, tumble dry low; remove promptly to reduce wrinkles.

Will the fitted sheet stay snug on tall or thick mattresses?

The fitted sheet is cut with deep pockets and features all-around elastic to secure the sheet on mattresses from 8" to 15" thick. This design minimizes slipping and re-tucking, keeping the bed neat through the night.

• All-around elastic grip prevents corners from coming loose.
• Deep-pocket fit accommodates thicker toppers and mattress profiles.
• Top/bottom tags simplify correct placement and faster bed-making.
