California Design Den Cotton Sateen King Sheet Set — Deep Pocket 8"–16", 400TC Soft Sateen

These are a 4-piece king sheet set woven from 100% long-staple cotton sateen with a 400 thread count and deep-pocket fitted sheet to fit mattresses 8"–16".

California Design Den’s king-size sheet set pairs a silky-smooth cotton sateen face with durable construction meant for everyday use. Independently tested and Good Housekeeping award–recognized, the set includes a flat sheet, a deep-pocket fitted sheet with full elastic, and two king pillowcases. The weave gives a subtle sheen that softens after washes while the cotton base keeps the fabric breathable and easy to launder.

How will these sheets feel and perform night after night?

The sateen weave produces a soft, smooth finish that feels pleasant against skin and breaks in over time to become even more comfortable. Long-staple cotton fibers resist pilling and keep the hand soft while breathability helps regulate temperature.

• 400 thread count single-ply long-staple cotton for a silky hand
• Sateen weave for light sheen and softness
• Designed to become softer with regular washing
• Independently tested for pilling, fading, and shrinkage

Will the fitted sheet stay secure on my mattress?

The fitted sheet features an all-around elastic grip engineered to hold corners and sides in place on mattresses up to 16" deep. Built-in top and bottom tags make orientation easy when making the bed.

• Deep-pocket fitted sheet fits 8"–16" mattresses
• All-around elastic for even tension and a snug fit
• Top/bottom tags speed up bed making and alignment

How do I care for these cotton sateen sheets to keep them looking their best?

These sheets are intended for frequent home laundering and are made to stand up to regular washing and tumble drying. Use warm wash and low tumble dry; removing promptly reduces wrinkles and helps preserve the finish.

• Machine wash warm; tumble dry low
• Remove promptly from dryer to minimize creasing
• Fabric tested for fade and shrink resistance

What comes in the set and what are the finished dimensions?

The set is a 4-piece king collection: one flat sheet, one deep-pocket fitted sheet, and two king pillowcases with a classic open-end design. Finished sizes are tested and provided for accurate fit.

• Flat sheet: 112" W x 102" L
• Fitted sheet: 78" W x 80" L (fits 8"–16" depth)

Who is this for? These sheets suit sleepers who want the silky feel of a sateen finish with the breathability of 100% cotton and reliable daily performance. They’re ideal for people who prefer a softer, slightly lustrous bedding look, owners of thicker mattresses who need true deep pockets, and anyone seeking easy-care linens backed by third-party testing and a brand with a track record of donations and responsible packaging.
