Extra Deep King Sheet Set - 6 Piece Breathable Cooling Navy

In this review the Extra Deep King Sheet Set is evaluated for sleepers who own very tall or pillow-top mattresses and want a soft, secure sheet set without fuss. The biggest reason to consider these sheets is the extra deep fitted sheet that reliably fits mattresses with pockets from 18 to 24 in, so the set stays put even with thick toppers. The six-piece arrangement includes four oversized pillowcases and a roomy flat sheet, delivering a breathable, microfiber feel that reviewers repeatedly note as softer than cotton and comfortable for nightly use.

Key Features

• Extra deep fitted sheet: Fits mattresses with pockets 18, 20, 21, 22 and 24 in deep, so it works with tall mattresses and thick toppers without slipping off.
• Secure elastic edge: Stretchable elastic around the fitted sheet gives a snug tug that keeps the sheet anchored at all four corners during sleep.
• Six-piece set: Includes one flat sheet, one extra deep fitted sheet and four oversized pillowcases with secure enclosures for a complete bed setup.
• Microfiber softness: The fabric is very soft with a light, cozy hand that reviewers feel is even softer than cotton.
• Great for pillow-top or memory foam: Designed to accommodate 3 in to 4 in toppers and memory foam layers without coming loose.

Who It's For

This sheet set is a strong choice for owners of extra tall mattresses, double pillow-top beds, or anyone who uses a thick mattress topper or memory foam layer and needs sheets that will not pop off the corners. Couples who toss and turn or people who dislike constantly re-tucking sheets will appreciate the deep pockets and elastic fit.

Shoppers who prefer a crisp cotton feel might look elsewhere, since these are microfiber sheets with a softer, less crisp hand. Also, those wanting fitted sheets for shallower mattresses under 18 in may find the extra depth unnecessary.

Pros & Cons

Pros

• Deep pockets fit mattresses up to 24 in and keep the fitted sheet in place.
• Four oversized 20 x 40 in pillowcases provide secure enclosures and a consistent look.
• Microfiber construction yields a very soft, breathable sleep surface that many reviewers prefer to cotton.

Cons

• The microfiber hand is softer and less crisp than cotton, which may not match every sleeper's preference.
