California Design Den 1000 TC King Sheet Set — 100% Long-Staple Cotton Sateen, Deep-Pocket 16"

These California Design Den king sheets are a heavyweight 1000 thread-count sateen set made from single-ply long-staple cotton for a smooth, substantial feel that softens with washing.

Designed for sleepers who want the look and durability of premium cotton without slippery thinness, this 4-piece king bedding set pairs a luminous sateen finish with a structured, weighty hand. Independently tested thread count, OEKO-TEX STANDARD 100 safety certification, and recognition from industry reviewers signal the set’s quality and responsible production. The collection includes a deep-pocket fitted sheet built to stay in place, a generously sized flat sheet, and two king pillowcases finished with classic hems.

How do these sheets feel and perform night after night?

The sateen weave gives a soft shimmer and a smooth surface while the single-ply long-staple cotton provides body and resilience. Expect the set to feel substantial rather than flimsy, and to relax into greater softness with repeated laundering. Breathable natural fibers help regulate temperature for year-round comfort without sacrificing structure.

• 100% long-staple cotton with a sateen weave for a smooth hand
• Substantial weight — not thin or silky-slippery
• Softens over time while retaining shape and comfort
• Designed for all-season use with natural breathability

What pieces are included and will they fit my mattress?

The set contains four items sized for a king bed: one flat sheet, one deep-pocket fitted sheet, and two king pillowcases. The fitted sheet is made to accommodate thicker mattresses with a gripping elastic that runs all the way around to hold mattresses up to 16 inches deep. Clear top/bottom tags make sheet placement and bed-making quicker.

• Flat sheet: 112" W × 102" L for full top coverage
• Fitted sheet: 78" W × 80" L fits up to 16" mattresses
• Pillowcases: 21" W × 41" L with side opening and 4" hem
• All-around elastic and placement tags for ease of use

How should I care for these sheets so they last and stay soft?

These cotton sheets are built for regular use and become softer with washing. Follow standard cotton care — machine wash warm and tumble dry low — and remove promptly to minimize wrinkles. OEKO-TEX certification means the fabric has been tested for harmful substances, and the set has been evaluated for pilling, fading, and shrinkage to support longevity.

• Machine wash warm; tumble dry low and remove promptly
• Becomes softer after repeated washes, similar to high-quality denim
• Designed and tested for low pilling, fading, and shrinkage
• OEKO-TEX STANDARD 100 certified for fabric safety
