Deep Pocket King Sheet Set Dark Grey - Fits Mattresses up to 21 in

In this review of the deep pocket king sheet set in dark grey, the bottom line is simple: these sheets suit sleepers who need a secure, soft cover for thick mattresses and who run warm at night. Our review finds the set stands out for its moisture-wicking finish and extra-deep fitted sheet, which together keep a pillow-top or topper in place while helping hot sleepers stay drier. The feel is plush from the brushed polyester and the pintuck edging gives a subtle, hotel-like look without being fussy.

Key Features

• Moisture-wicking 3M Scotchgard: Helps pull sweat away from skin so hot sleepers can sleep cooler and drier through the night.
• Deep pocket fit: Full elastic and a deep pocket secure the fitted sheet to mattresses and toppers up to 21 in thick so it resists shifting.
• Brushed polyester softness: The premium brushed fabric provides durable softness that remains comfortable after washing.
• Pintuck edging: Decorative pintuck details on the top sheet and pillowcases add texture and a refined bedroom aesthetic.
• Complete 4-piece set: Includes one flat sheet, one fitted sheet, and two pillowcases sized for king bedding needs.

Who It's For

These sheets are best for people with thick mattresses or mattress toppers-especially those with pillow-top beds-who need fitted sheets that stay put. They are also a good match for sleepers who tend to feel warm, since the 3M-enhanced moisture-wicking treatment helps manage overnight sweat.

Shoppers who want natural fibers or a very crisp percale feel should look elsewhere, as this set is 100% polyester with a brushed finish that favors softness over breathability of cotton. If you need fitted sheets for thin or low-profile mattresses, the extra-deep fit may feel generous in size.
