Mellanni Extra Deep Pocket Full Fitted Sheet - Perfect Fit for Tall

In this review of the Mellanni Extra Deep Pocket Full Fitted Sheet the bottom line is straightforward: this sheet is built for very tall mattresses and sleepers who want a consistently snug fit. Designed specifically for mattresses up to 21 in deep, the sheet's Z-fold elastic edging and full 21 in pocket depth mean it stays in place on extra-tall beds, pillow tops and mattress toppers. The fabric is Mellanni's double brushed microfiber, which feels soft and cool to the touch while offering fade, stain and wrinkle resistance suitable for busy bedrooms.

Key Features

• Extra deep pocket: A full 21 in pocket fits 17-21 in mattresses including pillow tops and toppers without popping off the corners.
• Z-fold elastic edging: Elastic runs all around the perimeter so the fitted sheet stays secure and resists shifting over night.
• Brushed microfiber: Double brushed construction gives a silky soft feel that is cooler and more durable than many cotton sheets.
• Easy care: Machine washable in cold and quick to tumble dry low, the sheet resists fading, staining, shrinking and wrinkling for low-maintenance use.
• Versatile use: Sized 75 x 54 x 21 in for a Full bed and suitable for bedrooms, guest rooms, RVs, waterbeds and adjustable bases.
• Lifetime promise: The brand offers a customer-focused return policy for peace of mind if the fit or feel is not right.

Who It's For

This fitted sheet is ideal for anyone with an extra-tall mattress, such as owners of memory foam, pillow top, topper-enhanced or adjustable beds who need a reliable fitted sheet that won't pop off. It also suits renters and vacation properties that need durable, easy-care bedding that holds up to frequent laundering.

Shoppers with standard-thickness mattresses under 16 in may prefer a classic fitted sheet from the same line for a closer fit, and those who prefer natural fibers over microfiber should consider other materials; this model emphasizes performance and easy care over a cotton or linen feel.
