CozyLux King Sheet Set, 21-Inch Deep Pocket

A 21-inch deep pocket paired with elastic around the entire fitted-sheet opening is the standout feature here: the sheet is designed to cover thick mattress corners and help reduce shifting or corner lift during everyday use. This CozyLux king set also includes four pillowcases, which is handy if you want the bed to look coordinated without buying extra cases separately.

The microfiber is 90 GSM, so the feel is intentionally lightweight rather than thick or heavy. If you prioritize easy handling and faster drying, that design may suit your routine, if you prefer substantial, weighty bedding, this set may not feel right for you.

Where it shines

The deep pocket is aimed at mattresses with a total profile of 18 to 21 inches, including the mattress, pillow top, topper, and pad. Measure that full stack before ordering. On a tall bed, the extra depth can make it easier to tuck the fitted sheet over the corners, while the all-around elastic helps keep the opening in place as you move around during the night.

For example, when making a bed with a thick topper, the elastic runs around the whole fitted-sheet opening rather than only at the corners. That gives the sheet coverage across the mattress edge and is intended to reduce corner lift. The tradeoff is fit: on a shallower mattress, the extra fabric may sit looser. From the way it is set up, accurate mattress-height measurement matters more than simply choosing a king size.

Highlights

The six-piece set contains one fitted sheet measuring 78 x 80 inches with a 21-inch deep pocket, one flat sheet measuring 105 x 102 inches with a 4-inch top hem, and four king pillowcases measuring 20 x 40 inches. The pillowcases have 4-inch envelope closures, pillows and decor are not included.

One side has a clean matte finish, while the other is lightly brushed for a soft touch. The lightweight microfiber is intended to be easier to handle when washing, folding, and making the bed. OEKO-TEX Standard 100 certification is listed, with certificate number 24.HCN.57362. Dark gray gives the set a simple, coordinated look, and the product description notes that other color choices are available.

Care tips

Machine wash cold on a gentle cycle, tumble dry on low, and do not bleach. The care instructions are straightforward, and the lighter construction is described as supporting quick drying. It is still worth following the gentle-cycle guidance rather than treating the sheets like a heavy-duty bedding item.

When it makes sense

Worth considering if you have a king mattress with a total height of 18 to 21 inches, want four matching pillowcases in the set, and prefer lightweight microfiber with a soft, brushed side. Better avoided if your mattress is much shallower, since the fitted sheet may have excess fabric, or if your priority is a thick, heavy feel. Compared with buying a simpler set with fewer pillowcases, this one gives you four, compared with choosing bedding mainly for substantial weight, its 90 GSM construction points in a lighter direction.
