Extra deep fitted sheets are designed to cover taller mattresses and help reduce corner lift and slipping. For queen beds measuring 18 to 24 inches deep, the CGK Unlimited fitted sheets and four-piece set offer the deepest stated fit in this selection. Utopia Bedding’s queen sheet fits up to 21 inches, while its king option fits up to 15 inches and is better for shorter mattresses. Check your mattress height, including any topper, before choosing.

Utopia Bedding Queen Grey Fitted Sheet
Best for: Queen mattresses from 18 to 21 inches deep when you need a fitted sheet only. It measures 60 by 80 inches and has an all-around elastic edge intended to help it stretch around the mattress base.
The brushed microfiber polyester fabric is described as breathable and soft. Choose this option if your mattress falls within its stated depth range and you do not need a complete sheet set. Its pocket depth is less than the 24-inch maximum offered by the CGK Unlimited choices, so it may not suit taller mattress-and-topper combinations.
CGK Unlimited Dark Grey Queen Sheet
Best for: Queen beds measuring 18 to 24 inches deep, including setups with a mattress topper. The fitted sheet has elastic all around the edge, which the product description says is intended to hug the mattress and help limit slipping and bunching.
CGK Unlimited lists double-brushed fabric and says the sheet is machine washable and treated to resist tearing, shrinking, wrinkling, staining, and fading. This is a useful choice for shoppers wanting a single fitted sheet in dark grey with a deeper fit than the Utopia queen option. Avoid it if your mattress is outside the stated 18-to-24-inch range or you need a full set rather than one sheet.
CGK Unlimited White Queen Sheet
Best for: Shoppers who want a white queen fitted sheet for a mattress 18 to 24 inches tall. Like the dark grey version, it is sold as a single fitted sheet and uses all-around elastic for a secure wrap.
The listed features include double-brushed fabric, machine washing, and treatments intended to resist several forms of wear, including fading and wrinkling. Its stated depth range makes it a better fit than a 15-inch-pocket sheet for a taller mattress. Because it is a fitted sheet only, choose another option if you need coordinating flat and pillowcase pieces in the same purchase.
CGK Unlimited Four-Piece Queen Sheet Set
Best for: Queen beds with an 18-to-24-inch mattress, especially when the setup includes a topper, pad, pillow top, or added foam layer. This four-piece set is designed for extra height and has strong all-around elastic, according to its product description.
The listing also identifies the fitted sheet as adjustable-bed friendly, noting that it is designed to flex as the bed changes position. Choose this product if you want a set rather than a fitted sheet alone or need a sheet intended for a thicker, moving bed setup. Confirm that the mattress dimensions and depth fit the listed range before ordering.
Utopia Bedding King Grey Fitted Sheet
Best for: King mattresses up to 15 inches deep. The sheet measures 78 by 80 inches, is made of microfiber, and has all-around elastic to help it fit the mattress base.
This is the only king-size option in the selection, but its stated pocket depth is shallower than the queen sheets above. It is better suited to a king bed of moderate height than to an extra-tall mattress with a substantial topper. Check the bed’s total height before choosing it; do not assume that “king” sizing also means extra-deep pockets.
Buying Guide: How To Choose Extra Deep Fitted Sheets
How deep should the pocket be?
Measure the mattress from its base to its highest point. Include a mattress pad or topper if it will remain on the bed beneath the sheet. Compare that total with the product’s stated pocket range: the queen options here cover 18–21 or 18–24 inches, while the king sheet is listed for mattresses up to 15 inches.
Should you buy a fitted sheet or a set?
A fitted-sheet-only product is suitable when you need a replacement bottom sheet or already own the other bedding pieces. A set is more practical when you want multiple coordinated components; the CGK Unlimited option is listed as a four-piece set. Check the product listing for the exact included pieces before purchase.
What helps a sheet stay in place?
Look for a pocket depth that accommodates the full mattress setup and elastic around the entire edge. The products described here list all-around elastic. A sheet that is too shallow may be difficult to secure, while one that is much deeper than necessary may not provide the fit you want.
Does color or fabric change the fit?
Color does not replace checking size and pocket depth. The listed choices include grey, dark grey, white, and light blue. Fabric descriptions vary: the Utopia sheets list microfiber, while CGK Unlimited describes its fitted sheets as double brushed. Consider both the stated fit and your preferred color and material description.
Frequently Asked Questions
What does extra deep mean for fitted sheets?
It means the sheet is designed with deeper pockets to cover a taller mattress than a standard-height fit may accommodate. Check the listed depth rather than relying on the label alone.
Can these sheets fit a mattress with a topper?
The CGK Unlimited queen options list a depth range of 18 to 24 inches, and the product descriptions identify topper use as a suitable setup. Measure the mattress and topper together to confirm the total height.
Is the king Utopia sheet extra deep?
It has a pocket depth of up to 15 inches. It may work for a king mattress at or below that height, but it is shallower than the queen options rated for up to 21 or 24 inches.
Are all the products complete sheet sets?
No. Several products are fitted sheets only. The CGK Unlimited light-blue queen option is described as a four-piece sheet set.
