Extra Deep Pocket King Bed Sheets 4-Piece Set - Fits 18-21in

In this review of the Extra Deep Pocket King Bed Sheets 4-Piece Set the bottom line is simple: this set is for anyone with a high-profile mattress who needs real depth and a tidy pillow closure. The reviewer found the defining benefit to be the 21in super extra deep fitted sheet that actually fits mattresses up to 23in and stays in place through the night. The fabric is soft microfiber and the package includes an oversized flat sheet and two zipper-closure pillowcases, making it a straightforward, practical upgrade for beds with toppers or pillow-top designs.

Key Features

• 21in Deep Pocket Fitted Sheet: Fits mattresses from 18 to 23in, so it accommodates high-profile and pillow-top mattresses without popping off.
• Super Oversized Flat Sheet: Extra-wide flat sheet designed to hang over more than standard flat sheets, providing full coverage for tall mattresses.
• 100% Ultra Soft Microfiber: The material delivers a soft, smooth feel that many users described as comfortable and cozy all night long.
• Zipper Closure Pillowcases: Hidden zippers keep pillows secure and create a neater appearance compared with flap closures.
• Low Care Maintenance: Machine washable and tumble dry low, the sheets claim to be wrinkle free, stain and fade resistant for easy upkeep.

Who It's For

This set is a clear choice for sleepers with thick mattresses, foam toppers or pillow-top layers who struggle with standard fitted sheets that slide off. Anyone wanting a tidy bed presentation will appreciate the zipper pillowcases and the oversized flat sheet that hangs lower than typical sheets.

Those who prefer natural fibers or seek a very cool, breathable sheet may want to look elsewhere, since this set is 100% microfiber and emphasizes softness over mattress-cooling performance. Shoppers who dislike zipper closures on pillowcases should note some customers reported mixed experiences with zipper durability.
