Extra Deep Pocket King Size Sheets 21 Deep Pocket - Calm Grey

In this review of the Extra Deep Pocket King Size Sheets 21 King Sheet Set, the bottom line is simple: these sheets are for anyone with a high-profile mattress who wants a soft, no-fuss bedding solution. The biggest reason to buy is the true 21' deep pocket design combined with an oversized flat sheet that actually covers tall mattresses, which solves the common problem of fitted sheets popping off or flats not hanging far enough. The set feels plush thanks to 100% ultra soft microfiber and includes two zipper pillowcases that keep pillows neatly enclosed.

Key Features

• 21' Super Extra Deep Pocket Fitted Sheet: Fits mattresses from about 18 to 23' deep so it stays in place on high-profile and pillow-top beds.
• Super Oversized Flat Sheet: The custom-fit flat sheet measures W 122 x L 110 to drape fully over tall mattresses and hang over the sides for tidy coverage.
• 100% Ultra Soft Microfiber: The fabric gives a soft, cozy feel that many customers describe as comfortable and sleep-enhancing.
• Two Zipper Closure Pillowcases: Hidden zipper closures keep pillows secure and present a neater look compared with flap closures.
• Easy Care: Machine washable, tumble dry low, wrinkle resistant and fade resistant for a low maintenance bedding option.

Who It's For

This set is best suited for owners of high-profile mattresses, pillow-top beds, foam toppers or layered sleep systems who need extra fabric to keep sheets neat and secure through the night. Couples who share a deep king mattress and want full coverage from a single oversized flat sheet will appreciate the generous dimensions.

Shoppers with standard or very thin mattresses may find the 21' pocket and oversized flat sheet more fabric than necessary and could prefer a traditional 14' fitted sheet set. If you want natural fibers only, note these are 100% microfiber rather than cotton or linen.

Pros & Cons

Pros

• Very deep fitted sheet holds well on tall mattresses and layered toppers.
• Oversized flat sheet provides generous side and end coverage for tidy bedding.
• Soft microfiber delivers a comfortable, smooth sleep surface with minimal break-in.
• Zippered pillowcases offer a neater, more secure pillow enclosure than flap styles.

Cons

• Some users report mixed sizing impressions: the flat sheet can be very wide for certain beds and a few have had issues with zipper durability.
• Microfiber may not be preferred by those who want natural fiber sheets for breathability.
