California Design Den Organic Cotton Percale King Sheet Set, White — 300TC, GOTS Certified

These are 100% organic cotton percale king sheets in white, designed to deliver a crisp, breathable, and long-lasting bed linen experience.

California Design Den’s king-size sheet set uses a classic percale weave for a matte, cool hand feel that softens with repeated washing while maintaining structure and durability. GOTS certified and carrying the Good Housekeeping Seal, this four-piece collection includes a flat sheet, a deep-pocket fitted sheet with full elastic, and two envelope-closure pillowcases sized for standard king pillows.

What makes percale cotton different from other sheet weaves?

Percale is a plain, tight weave that produces a matte finish and a crisp, cooling touch, unlike the glossy, silky surface of sateen weaves. It’s favored by sleepers who want a fresh, airy surface that breathes well through the night and becomes softer over time without losing its structure.

• Crisp, matte finish — not shiny or slippery
• Breathable weave ideal for warmer sleepers
• Ages softer after repeated washing while staying durable
• 300 thread count for a balance of body and breathability

How do these sheets fit and care for a king mattress?

The set contains one fitted sheet with an all-around wide gripper elastic designed to secure mattresses up to 15 inches deep, a generously sized flat sheet, and two king pillowcases with envelope closures. Care is straightforward: machine wash warm and tumble dry low, remove promptly to reduce wrinkles and preserve the percale hand.

• Fitted sheet fits mattresses up to 15" deep
• Flat sheet dimensions: 112" × 102" for full coverage
• Pillowcases: 21" × 36" with envelope closure to protect inserts
• Machine wash warm; tumble dry low; remove promptly

Are these sheets sustainably made and tested for quality?

Yes — the fabric is GOTS (Global Organic Textile Standard) certified, which verifies organic fiber content and environmental/social responsibility in manufacturing. The set is independently tested and carries the Good Housekeeping Seal, which reflects durability checks such as resistance to shrinking, pilling, and tearing.

• GOTS certification for organic cotton and ethical processing
• Good Housekeeping Seal for independent quality testing
• Produced in a family-run factory with supply chain transparency
• Brand supports charitable donations and social responsibility

How will these sheets feel night after night?

On first use they feel crisp and cool—similar to a well-pressed cotton shirt—and they loosen into a softer, lived-in hand with regular laundering. The percale construction keeps airflow high, helping regulate temperature while providing a textured, breathable sleep surface that many people find refreshing.

• Starts crisp, becomes softer with washes
• Breathable surface reduces trapped heat
• Durable 300 thread count resists pilling and tearing
• Matte finish for a clean, hotel-like look

Who is this for: these king-size sheets suit sleepers who prefer a cool, airy, and structured cotton rather than a silky finish — ideal for warm-weather sleepers, fans of a classic hotel-style bed, and anyone prioritizing organic, third-party certified textiles. If you want white, responsibly made, long-lasting linen that softens over time while retaining a crisp profile, this set from California Design Den is a practical choice.
