King Fitted Sheet Deep Pocket 18"-21" Extra Deep Pocket Fitted Sheet, Gray Review (2026)
Updated September 14, 2026 · Research-based review
Our verdict
This gray King fitted sheet is a budget option for deep mattresses up to 21 inches, sold as a single replacement rather than part of a set. It suits fitting a thick mattress cheaply in a neutral color, but the listing does not name a brand or fabric type, so buyers are taking softness and durability on faith.

Who this sheet is built for
This is a single fitted sheet, not a bundled set with a flat sheet or pillowcases, aimed at buyers who already own the rest of their bedding and just need a replacement fitted sheet sized for a deep King mattress. The 18 to 21 inch pocket depth covers most memory foam and hybrid King mattresses, including many that carry a mattress topper, without needing the even deeper pockets that ultra thick mattresses require. The gray color is a practical choice for anyone who wants a neutral sheet that hides everyday wear, pet hair and lint better than a bright white sheet would between washes. Buyers furnishing a full new bedding set, or anyone who wants a named, established brand with a track record on fabric quality, should compare this against sheets from established linen brands before buying, since this listing does not identify either.
Pocket depth and what is not specified
The core, verified spec for this sheet is its 18 to 21 inch deep pocket, sized for King mattresses that are taller than a standard 10 to 14 inch mattress but not deep enough to need the 24 inch pockets some extra thick sheets offer. Unlike several other fitted sheets in this guide, the product listing for this sheet does not state a brand name or a specific fabric type such as cotton, microfiber or a percale weave, which makes it harder to predict how the fabric will feel or hold up over repeated washing compared with sheets that do list those details. That gap is worth factoring into the purchase decision, since fabric composition is normally one of the biggest drivers of how soft a sheet feels and how long it lasts before pilling or thinning. Buyers who want that certainty should prioritize listings that state a fiber content.
Living with it day to day
As a single item rather than a set, this sheet is best suited to replacing a worn out fitted sheet while keeping an existing flat sheet and pillowcases in the same or a coordinating color. The 18 to 21 inch pocket should stretch over most deep King mattresses without excessive slack, though buyers with mattresses right at or above the 21 inch limit, especially with an added topper, may find the fit tighter than sheets rated to 24 inches. Because fabric type is not specified, care instructions should be treated cautiously: a gentle, cool water wash and low heat dry is the safer default until the actual fabric behavior is known from experience with the specific sheet. The gray color is a practical everyday choice that should resist showing stains and pet hair as noticeably as a lighter colored sheet.
How it compares with other deep pocket sheets
Against the CGK Unlimited King fitted sheet in the same guide, which is confirmed to use a double brushed fabric and covers pockets up to 24 inches, this gray sheet has a shallower maximum pocket depth and an unconfirmed fabric type, making CGK the safer choice for very thick mattresses or buyers who want assurance about fabric quality. Compared with the Hearth and Harbor six piece sheet set, this listing is a single item at a lower price point rather than a full coordinated set. Against the two Split King sheets also reviewed in this guide, this sheet fits standard one piece King mattresses rather than the two piece mattresses used on adjustable bases, so the right choice depends entirely on the mattress setup at home.
Verdict and who should pick something else
This sheet is a reasonable, budget minded pick for anyone who needs a single replacement fitted sheet for a deep King mattress up to 21 inches and is comfortable buying without a stated brand or fabric type. It works best as a practical, no frills fix rather than a foundation for a new bedding set. Buyers who want documented fabric quality, a full matching set, or a pocket depth up to 24 inches for an especially thick mattress and topper combination should choose the CGK Unlimited sheet or a similarly detailed listing in this guide instead. Anyone shopping primarily on fabric feel and long term durability should treat the missing spec here as a real gap, not a minor detail.
Frequently asked questions
What mattress depth does this sheet fit?
The pocket is sized for King mattresses from 18 to 21 inches deep, which covers most memory foam and hybrid mattresses.
Does this listing include a flat sheet or pillowcases?
No, this is a single fitted sheet only, sold separately from any matching flat sheet or pillowcases.
What fabric is this sheet made from?
The listing does not specify a fabric type or fiber content, so softness and durability cannot be confirmed from the product page alone.
Is this sheet a good fit for a very thick mattress with a topper?
If the combined mattress and topper height is close to or above 21 inches, a sheet rated to 24 inches, like the CGK Unlimited option in this guide, is a safer choice.
