Mellanni Extra Deep Pocket Queen Fitted Sheet - Fits up to 21in

In this review the Mellanni Extra Deep Pocket Queen fitted sheet is evaluated for sleepers who need a reliable cover for very thick mattresses. The bottom line: this sheet's defining strength is its extra deep 21in pocket and Z-fold elastic edging, which stays put on 17-21in mattresses and makes it a sensible choice for memory foam toppers, pillow tops, adjustable beds and RV mattresses. The review focuses on fit, fabric feel and care, and whether this single-piece fitted sheet delivers practical value for everyday use.

Key Features

• Extra deep pocket: The 21in pocket design fits 17in to 21in mattresses so tall mattresses and thick toppers stay fully covered without popping off.
• Z-fold elastic edging: Elastic runs all the way around, not just the corners, keeping the fitted sheet secure and reducing shifting during the night.
• Brushed microfiber: Double brushed microfiber gives a soft, silky feel that is more durable and less prone to pilling than lower quality synthetics.
• Easy care: The fabric is fade, stain, shrink and wrinkle resistant and can be machine washed cold and tumble dried low for low-maintenance laundering.
• Versatile use: Sized 80in x 60in x 21in, it is suitable for bedrooms, guest rooms, RVs and adjustable beds, and works with mattress pads and toppers.
• Lifetime promise: The brand offers a lifetime return policy for customer satisfaction, allowing returns without hassle if expectations are not met.

Who It's For

This fitted sheet is for people with extra tall mattresses - think 17in to 21in thickness - including those who use memory foam toppers, double pillow tops, or substantial mattress pads. It is also a good pick for homeowners who want an easy-care, pet-friendly sheet that resists fade and stains and dries quickly.

Shoppers who prefer natural fibers or who need a fitted sheet for mattresses 16in and under should consider the brand's classic collection or other cotton options instead, since this extra deep microfiber sheet is optimized for deep pockets and synthetic fabric care advantages.

Pros & Cons
