California Design Den King Cotton Sateen Sheet Set - Ivory 4-Pc, 400TC, Deep Pockets

These are California Design Den’s 100% long-staple cotton sateen king sheets: a 4-piece, 400-thread-count set in ivory with deep pockets that won the 2026 Good Housekeeping Best Bedding Award.

Designed for everyday comfort and easy care, this king sheet set includes a flat sheet, a deep-pocket fitted sheet that fits mattresses 8"–16" and two king pillowcases. The single-ply long-staple cotton and sateen weave create a smooth, lightly lustrous surface that becomes softer with each wash while remaining breathable and durable for regular laundering.

How will these sheets feel night after night?

The sateen weave gives a silky, smooth hand with a subtle sheen, while the long-staple cotton maintains strength and breathability. Expect a softer, lived-in feel after repeated washing without losing structure.

• 400 thread count, single-ply long-staple cotton for a soft yet durable fabric
• Sateen weave for a smooth, slightly lustrous finish
• Fabric softens with each wash while remaining breathable

Will the fitted sheet stay secure on my mattress?

The fitted sheet has all-around elastic grip and deep pockets designed to fit mattresses from 8" to 16" thick, helping reduce slipping and shifting. Top/bottom tags make orientation and bed-making straightforward.

• All-around elastic for a snug fit around the mattress
• Deep pockets accommodate 8"–16" mattress depths
• Top and bottom tags simplify correct placement

How easy are these sheets to care for and maintain?

These sheets are made for routine home laundering and are tested for fading, pilling and shrinkage. Follow machine wash warm and tumble dry low instructions; removing promptly helps minimize wrinkles.

• Machine washable warm; tumble dry low recommended
• Pre-tested for pilling, fading, and shrinkage to withstand regular use
• Softens over time similar to familiar wardrobe pieces like denim

What does the ivory color and set include?

The ivory tone is a pale, neutral shade without creamy or buttery undertones, offering a luminous, calming backdrop for bedroom decor. The 4-piece king set contains one flat sheet, one deep-pocket fitted sheet, and two king-size pillowcases with open-end design.

• Ivory shade: pale and neutral, free from yellow or butter tones
• Set contents: 1 flat sheet (112" x 102"), 1 fitted sheet (78" x 80"), 2 pillowcases (21" x 40")
• Classic open-end pillowcases and finished sizes printed for easy reference

Who is this for: These sheets suit anyone seeking a breathable, soft cotton sateen set with a refined look and reliable fit—especially people with deeper mattresses or those who prefer bedding that becomes softer with use. The Good Housekeeping recognition and independent thread-count verification appeal to shoppers who value tested quality and responsible production practices. California Design Den’s recyclable packaging and history of charitable donations also make this set a thoughtful choice for socially conscious buyers.
