For a deep double bed, choose sheets by checking the mattress size and total depth, including any topper. The CGK Unlimited Extra Deep Full Sheet Set is best for a 18–24-inch mattress, while its fitted-sheet-only option suits shoppers who need to replace just that piece. The two standard CGK sets fit mattresses up to about 16 inches, and Bedsure offers a soft microfiber set with no pocket-depth measurement listed.

| CGK Dark Grey 4-Piece Set | Mattresses up to 16 inches | Up to about 16 inches |

CGK Unlimited Extra Deep Full Sheet Set
Best for: Full or double beds with a mattress 18–24 inches deep, including setups with a topper, pillow top, mattress pad, or added foam layer. The listed fit range makes this the clearest choice among these products for a particularly thick mattress.
The four-piece set is designed with an all-around elastic fitted sheet to help limit corner lift, slipping, and bunching. It is also described as adjustable-bed friendly, which may suit beds that move between positions. Choose this set when the mattress depth falls inside its stated range; a mattress shallower than 18 inches may not need extra-deep pockets.
CGK Extra Deep Full Fitted Sheet
Best for: Shoppers who need a deep-pocket fitted sheet without replacing their flat sheet and pillowcases. It is made for mattresses 18–24 inches deep, and the listed all-around elastic is intended to help the sheet hug the mattress.
The manufacturer describes the fabric as double-brushed and machine washable, with treatments intended to resist tearing, shrinking, wrinkling, staining, and fading. This is a single fitted sheet, not a complete bedding set. Avoid it if you need a flat sheet and pillowcases included or if your mattress is outside the stated depth range.
CGK Unlimited White Full Sheet Set
Best for: A standard-depth full or double mattress measuring up to about 16 inches. The four-piece set includes a fitted sheet, flat sheet, and two pillowcases. Listed dimensions are 75 by 54 inches for the fitted sheet, 96 by 81 inches for the flat sheet, and 20 by 30 inches for each pillowcase.
The sheets are described as breathable, cooling, and silky soft. Choose this set if your mattress and any added bedding stay within the approximately 16-inch limit. It is not the best fit for a mattress deeper than that; consider an extra-deep option instead.
CGK Unlimited Dark Grey Full Sheet Set
Best for: Buyers who want the same stated dimensions and depth range as the white CGK set in dark grey. This four-piece set includes a fitted sheet, flat sheet, and two pillowcases. Its fitted sheet is listed at 75 by 54 inches and is designed for mattresses up to about 16 inches deep.
The brand describes the set as breathable, cooling, and soft. It is a straightforward alternative when color is the main difference that matters. Avoid choosing it for a thicker mattress or topper combination that pushes the total depth beyond the stated fit range.
Bedsure Full Size Microfiber Sheet Set
Best for: Shoppers seeking a soft-feeling polyester microfiber set with decorative details. It includes four pieces, and the product description highlights fabric brushed on both sides, plus a ruched hem on the pillowcases and flat sheet.
The listed material is 100% polyester. The product details provided do not specify a pocket depth, so confirm the fit information on the product listing before selecting it for a deep mattress. This is a less certain choice than the CGK options when mattress depth is the deciding factor.
Buying Guide: How To Choose Sheets For A Deep Double Bed
How deep is your mattress with bedding added?
Measure from the bottom edge of the mattress to its top surface. Include a mattress topper, pad, or other layer that the fitted sheet must cover. Compare that total with the product’s stated pocket-depth range. A set listed for mattresses up to about 16 inches is not equivalent to one designed for 18–24 inches.
Do you need a complete set or only a fitted sheet?
A four-piece set is useful when you need a flat sheet and pillowcases along with the fitted sheet. A fitted-sheet-only product can be more practical when your other bedding is still in good condition. Check the product contents rather than assuming every listing includes the same pieces.
Is “double” the right size to search for?
These listed products are labeled full size. In U.S. bedding searches, “double” is often used for the full-size bed category, but check the fitted-sheet dimensions against your mattress before buying. This matters especially if your mattress has unusual dimensions or a thick profile.
What else should you compare?
- Fit range: Match the pocket depth to the complete mattress setup.
- Fabric: Compare the listed microfiber or polyester details and the feel you prefer.
- Secure fit: Look for descriptions of all-around elastic if staying in place is a priority.
- Set contents: Confirm whether the listing includes a flat sheet and pillowcases.

It depends on the combined depth of the mattress and topper. Measure both together and compare the total with the sheet’s stated maximum depth.

No. It is listed as a fitted sheet only, so it does not include a flat sheet or pillowcases.
