A tall mattress can turn an ordinary fitted sheet into a nightly hassle: shallow pockets may pull loose, bunch up, or expose the mattress corners. The right set needs a fitted sheet with enough pocket depth for your mattress and any topper, plus a fabric and set size that suit how you sleep. These picks cover mattresses up to 18–24 inches deep, with options in brushed microfiber and bamboo-derived rayon.

Our Picks: Best Sheets For Tall Mattress reviews
Hearth & Harbor Queen Sheets: Deepest Fit with Extra Pillowcases
This queen set is designed for mattresses from 18 to 24 inches deep, making it a strong option for a tall mattress or one paired with a thick topper. The fitted sheet measures 60 by 80 inches, and the set also includes a 90-by-102-inch flat sheet and four pillowcases.
The fabric is double-brushed microfiber. The product description says it is made to resist pilling, snagging, fading, stains, shrinking, and wrinkles, and recommends machine washing in cold water and tumble drying on low. Those care and durability features may appeal if you want a practical set for frequent use, though microfiber may not be the feel you prefer if you favor natural-fiber bedding.
Compared with the other options here, this set pairs a 24-inch pocket depth with four pillowcases. Check your mattress depth before buying: the listed fit range starts at 18 inches, so it may not be the best match for a shallower mattress.
Pros:
- Fits mattresses up to 24 inches deep
- Includes four pillowcases
- Double-brushed microfiber is described as soft
- Designed to resist common wear and laundry issues
Cons:
- Queen size only in the supplied product details
- Microfiber may not suit shoppers who prefer a different fabric feel
Verdict: Choose this queen set if your mattress is 18–24 inches deep and you want a deep-pocket microfiber option with four pillowcases.
Bedsure Full Sheets: A Moisture-Wicking Option for a Tall Full Mattress
This full-size set fits mattresses up to 21 inches thick. It includes a 54-by-75-inch fitted sheet, an 81-by-96-inch flat sheet, and two 20-by-30-inch pillowcases. The fitted sheet has full elastic, which is intended to help it stay in place around a thicker mattress.
Bedsure describes the brushed fabric as soft and adds a 3M Scotchgard moisture-wicking finish. That feature may be worth considering if you tend to sleep warm or want bedding designed to help manage moisture. The pintuck edges on the pillowcases and top sheet add a more decorative detail than the plainer styles in this list.
This is the only full-size option among these picks, but its maximum depth is three inches less than the 24-inch options. Measure your mattress and topper together; if the combined depth exceeds 21 inches, look at one of the deeper sets instead.
Pros:
- Fits full mattresses up to 21 inches thick
- Moisture-wicking finish is designed to help keep sleepers drier
- Full elastic is intended to help secure the fitted sheet
- Pintuck details add texture to the set
Cons:
- Does not fit mattresses deeper than 21 inches, according to the listed specifications
- Includes two pillowcases rather than four
Verdict: This is a sensible full-size pick for a mattress up to 21 inches deep, especially if moisture-wicking details and a decorative finish matter to you.
Hearth & Harbor King Sheets: Extra-Deep Coverage for Larger Beds
This king-size set has a fitted sheet made for mattresses 18–24 inches deep. It measures 78 by 80 inches, with a 105-by-102-inch flat sheet and four 20-by-40-inch pillowcases. The larger pillowcases are sized for king pillows.
Like the queen version, it is made from double-brushed microfiber. The product description highlights resistance to pilling, snagging, fading, stains, shrinking, and wrinkles, along with cold-water machine washing and low-temperature tumble drying. That makes it a practical option if you want a matching deep-pocket set for a tall king mattress without switching to a different fabric type.
The main difference from the queen set is the bed and pillowcase sizing, not the stated pocket depth or material. It starts at 18 inches deep, so check that your mattress is within the listed range rather than assuming a deep-pocket sheet will fit every mattress height.
Pros:
- Fits king mattresses 18–24 inches deep
- Includes four king-size pillowcases
- Double-brushed microfiber construction
- Designed to resist pilling, snagging, and fading
Cons:
- Listed fit range begins at 18 inches deep
- Microfiber is not a natural-fiber option
Verdict: Pick this set for a tall king mattress when you want 24-inch pocket depth, microfiber construction, and four king pillowcases.
AiAngu Bamboo-Derived Queen Sheets: Silky Feel for Deep Mattresses
AiAngu’s queen set is made from 100% rayon derived from bamboo and is sized for mattresses 18–24 inches deep. It includes a 60-by-80-inch fitted sheet, a 92-by-102-inch flat sheet, and two 20-by-30-inch pillowcases. The fitted sheet has a double-stitched elastic hem.
The product description emphasizes a smooth, breathable feel and moisture-wicking properties, positioning the fabric as an option for people who tend to sleep warm or prefer a silky drape. It also describes the fabric as twill woven and says the set is machine washable and resistant to fading and wrinkling. Rayon derived from bamboo is not the same as a sheet made from raw bamboo fiber, so check the material wording if that distinction matters to you.
Its 24-inch maximum depth matches the deepest options in this roundup, while the set includes fewer pillowcases than the Hearth & Harbor sets. It may suit you if fabric feel is a priority, but shoppers seeking a less smooth or more familiar microfiber feel may prefer another pick.
Pros:
- Fits mattresses 18–24 inches deep
- Rayon derived from bamboo with a silky-smooth feel
- Designed to wick moisture and promote airflow
- Double-stitched elastic hem on the fitted sheet
Cons:
- Includes two pillowcases
- The listed fit range starts at 18 inches deep
Verdict: Consider this set if you want a deep-pocket queen sheet in bamboo-derived rayon and prefer a smooth, breathable feel.
Bedsure Stay-Put Queen Sheets: Reinforced Fit for Mattresses up to 18 Inches
This queen set is made for mattresses, toppers, or air mattresses from 16 to 18 inches deep. It includes a 60-by-80-inch fitted sheet, a 90-by-102-inch flat sheet, and two 20-by-30-inch pillowcases. Its stated maximum depth is lower than the 21- and 24-inch options above, so it is best for a tall mattress that remains within that range.
The design uses reinforced corners and a 2-centimeter-wide, six-layer elastic band to help reduce shifting and popped corners. The fabric is described as wear-resistant and pet-friendly, and the materials are listed as certified to OEKO-TEX Standard 100. The set’s reinforced fit may be useful if a fitted sheet tends to move on your bed, but it cannot make up for a mattress that is deeper than the stated limit.
Compared with the other queen options, this set focuses on staying in place rather than covering the deepest mattresses or including extra pillowcases. Measure your mattress and topper together before choosing it.
Pros:
- Reinforced corners and a wide elastic band are designed to help keep the sheet in place
- Fits mattresses 16–18 inches deep
- Includes a full queen-size sheet set with two pillowcases
- Materials are listed as OEKO-TEX Standard 100 certified
Cons:
- Maximum listed depth is 18 inches
- Includes two pillowcases rather than four
Verdict: Choose this set if your queen mattress is no deeper than 18 inches and a reinforced, stay-put fit matters more than extra pocket depth.
How to Choose Sheets for a Tall Mattress
Measure the full mattress depth
Measure from the bottom edge of the mattress to the top surface, including any pillow top or attached cushioning. If you use a separate topper, include that too. Compare the total with the fitted sheet’s stated depth range. A sheet labeled for up to 18 inches may not fit a 20-inch mattress securely, even if it is called deep pocket.
Check the fitted sheet’s dimensions and fit range
Pocket depth is only one part of fit. Confirm the sheet is made for your mattress size—such as queen, king, or full—and check the fitted sheet’s listed length and width. If the product lists a range, make sure your mattress falls within that range rather than only under its maximum depth.
Choose a fabric that suits your sleep preferences
The sets here include brushed microfiber and rayon derived from bamboo. Microfiber is the choice in the Hearth & Harbor sets, while the bamboo-derived rayon set is described as smooth and breathable. The Bedsure full set adds a moisture-wicking finish. Fabric feel is personal, so use the material details to narrow your options instead of relying on pocket depth alone.
Consider how the fitted sheet stays in place
A fitted sheet with full elastic or reinforced corners may help it stay put, especially if your mattress has a smooth surface or you use a topper. Still, a secure design cannot replace the right pocket depth. If your sheet regularly slips, check both the mattress measurement and the construction details before switching to a new set.
Compare what comes in the set
Sets can differ in the number and size of pillowcases, as well as in flat-sheet dimensions. The Hearth & Harbor options include four pillowcases, while the other listed sets include two. Check whether the pillowcases match your pillows and whether the flat sheet dimensions suit your bed and preferred amount of coverage.
Review care instructions before buying
Care details vary by product. For example, the Hearth & Harbor sets specify cold-water machine washing and tumble drying on low, while the other descriptions note different care or wrinkle-resistance features. Follow the instructions supplied with the specific set to help maintain its fabric and fit.
Frequently Asked Questions
How deep should fitted sheets be for a tall mattress?
Choose a fitted sheet whose stated depth range includes your mattress’s total thickness. Measure the mattress with any topper in place, then allow for the pocket depth listed by the manufacturer. The options here range from a maximum of 18 inches to a maximum of 24 inches.
Will a 24-inch pocket sheet fit a mattress that is 18 inches deep?
It may, if the product’s stated fit range includes 18 inches. Some sets in this roundup list a range of 18–24 inches, while another is designed for 16–18 inches. Check the full range rather than relying on the maximum alone.
Should I include a mattress topper when measuring?
Yes. Measure the mattress and topper together if you plan to leave the topper on the bed. The combined depth is what the fitted sheet needs to cover.
Are all deep-pocket sheets made from the same fabric?
No. These choices include double-brushed microfiber, brushed fabric with a moisture-wicking finish, and rayon derived from bamboo. Check the product details for both the fabric and any added features so you can choose the feel you prefer.
Do deeper sheets always stay on the mattress better?
Not necessarily. The sheet needs enough pocket depth to cover the mattress, but a pocket that is much deeper than needed may not give the fit you want. Elastic construction and reinforced corners can also matter, so consider both fit range and design.
Which option is best for a king mattress?
The Hearth & Harbor king set is the only king-size choice in this list. Its fitted sheet is listed for mattresses 18–24 inches deep and the set includes four king-size pillowcases.
Which pick is best for a mattress deeper than 21 inches?
The Hearth & Harbor queen and king sets and the AiAngu queen set are listed for mattresses up to 24 inches deep. Confirm that your mattress size matches the set and that its depth falls within the product’s stated range.
Final Recommendation
For the broadest depth range, the Hearth & Harbor sets are the most straightforward choices: the queen and king versions both fit mattresses listed at 18–24 inches deep. Choose the queen or king size that matches your bed. If you prefer a smooth bamboo-derived fabric, consider AiAngu; for a full bed up to 21 inches deep, look at Bedsure’s moisture-wicking set. Measure your mattress and topper together before ordering to get the most reliable fit.
