California Design Den 100% Cotton Sateen Twin Sheets — Bright White 3‑Pc Set, Soft & Breathable, Fits 12" Mattresses

These are a 3-piece twin sheet set from California Design Den made of 100% cotton sateen, delivering a crisp yet soft white bedding option that breathes and softens with each wash.

Designed for everyday comfort and easy care, this twin bedding set includes a fitted sheet, a flat sheet and a pillowcase sized to fit standard twin mattresses up to 12" deep. The sateen weave gives the fabric a subtle sheen and smooth hand, while the natural cotton fiber promotes airflow for a comfortable sleep environment through all seasons. Independently tested and awarded the Good Housekeeping Seal, the set ships in recyclable packaging and is produced in a family-run factory in India.

How will these sheets feel on the bed?

The sateen weave creates a silky, smooth surface with a soft, natural hand from 100% cotton. The set arrives with a slightly crisp finish that relaxes and becomes softer after several washes, balancing initial structure with long-term comfort.

Do these sheets fit my mattress and stay in place?

The fitted sheet is designed to fit mattresses up to 12" deep and includes all-around elastic to reduce slipping. Tagging on the top and bottom of the fitted sheet simplifies orientation when making the bed, and the envelope-style pillowcase keeps the pillow secure.
