Fitted King Size Sheets Deep Pocket 400 TC Cotton - Sky Blue

In this review of the fitted king size sheet from California Design Den, the bottom line is simple: anyone with a deep mattress who wants a soft, natural cotton sheet that stays put will appreciate this single fitted sheet. The review focuses on the sheet's snug fit and fabric quality, highlighting the 400 thread count sateen made from long-staple 100% Indian cotton and an all-around elastic that prevents slipping on mattresses up to 16 in deep. The color is a muted pale sky blue with gray undertones, and the sheet is sold as one fitted piece measuring 78 in W x 80 in L.

Key Features

• Deep pocket fit: Premium all-around elastic and 16 in deep pockets keep the sheet securely in place on low foam and tall mattresses without bunching.
• 400 thread count sateen: A soft, smooth sateen weave offers a breathable surface that becomes softer with each wash for lasting comfort.
• 100% long-staple cotton: Natural cotton construction provides a cool, breathable sleep surface that avoids the plastic feel of synthetic microfiber.
• Color description: The sky blue shade is a serene pale blue with soft gray undertones for a muted, airy bedroom look rather than a bright or baby blue.
• Easy care and safety: Machine washable, resistant to shrinking, pilling, and fading, and Standard 100 by Oeko-Tex certified for low harmful substances.
• Durable construction: Quality stitching and long-staple yarns are designed to hold up over years of use without losing softness.

Who It's For

This fitted sheet is ideal for shoppers who sleep hot or prefer natural fibers, and for anyone with a mattress that needs a deep pocket solution; the 16 in depth and elastic all around make it a reliable choice for thicker foam or topped beds. Its muted sky blue works well for calm, minimalist bedrooms where a soft, neutral color is preferred.

People who want a full sheet set or prefer a brighter, more saturated blue should look elsewhere, since this listing is for a single fitted sheet and the color is intentionally pale with gray undertones. Buyers seeking high-gloss sateen shine or synthetic easy-dry performance from microfiber may also prefer a different material.

Pros & Cons

Pros

• Soft, breathable 400 thread count sateen made from 100% long-staple cotton that softens with washing.

• Oeko-Tex Standard 100 certification and durable construction mean safer materials and long-term use.
• The muted sky blue adds a calm, airy look without being overly bright.

Cons

• Sold as a single fitted sheet only, so additional flat sheets and pillowcases must be purchased separately.
• The pale blue is muted with gray undertones, which may not match expectations for a bright blue.
