California Design Den Soft 100% Cotton Twin XL Sheet Set – 400 TC, Good Housekeeping Award Winner

Premium comfort you can count on

Discover the California Design Den Soft 100% Cotton Twin XL Sheet Set, designed to bring calm and everyday ease to your nights. Awarded in recognition of thoughtful design and performance, this 400-thread-count set uses a single-ply 100% long-staple cotton for a smooth hand feel that stays lightweight and breathable. The result is a refined, velvety surface that pairs well with many duvets and blankets, making it a versatile addition to a modern bedroom.

Complete 3-piece Twin XL configuration

This set includes a flat sheet, a deep-pocket fitted sheet with all-around elastic grip to fit mattresses from 8" to 15", and a standard pillowcase. Finished sizes are practical for bed making: flat sheet wide enough to tuck, fitted sheet snug at the corners, and a pillowcase sized for everyday comfort. Small details like top and bottom tags can help you speed up bed making without sacrificing style.

Soft comfort that lasts

The sateen weave delivers a silky, lustrous feel that softens with each wash while maintaining breathability for year-round comfort. The naturally smooth texture is gentle on skin, making it a comfortable option for restful nights and relaxed mornings alike.

Durable and easy to care for

Crafted from 100% cotton, this bedding is built to handle regular laundering while preserving its shape and sheen. It’s been tested for pilling, fading, and shrinkage, and it only gets softer over time—much like your favorite everyday apparel. For best results, wash warm, tumble dry low, and remove promptly to minimize wrinkles.

Craftsmanship you can trust

California Design Den has built a reputation since 2017 for thoughtful products and transparent practices. The thread count is independently verified, and the brand supports community impact with donations of sheet sets across the U.S. Each set is thoughtfully produced in a family-run factory in India and shipped in recyclable, plastic-free packaging, reflecting a straightforward commitment to responsible sourcing and quality.
