Finding the best sheets for an extra-long twin bed starts with checking the fitted-sheet size and pocket depth. Twin XL sheets are made for a longer mattress than standard twin sheets, but pocket depth, included pieces, and fabric can vary. These five options include full sets, extra-deep designs, and a fitted sheet sold on its own, so you can choose what suits your bed and sleeping habits.

Our Picks: Best Sheets For Extra Long Twin Bed reviews
CGK Unlimited: A Soft, Straightforward Twin XL Set
This three-piece set is a practical pick if you want the main bedding pieces in one package. It includes a 39-by-80-inch fitted sheet, a 66-by-102-inch flat sheet, and one 20-by-30-inch pillowcase. The fitted sheet is designed for mattresses up to about 16 inches deep.
The fabric is double-brushed microfiber, which the brand describes as breathable, cool, and silky soft. Microfiber is a useful option if you prefer a smooth feel and want sheets that are easy to care for. The set is also positioned as an affordable choice for bedrooms, guest rooms, and dorm-style spaces.
One detail to keep in mind is the single pillowcase. If you use two pillows, you’ll need another case. And while the fitted sheet should suit many mattresses, it may not have enough depth for a thick mattress or a bed with a topper that adds height.
Pros:
- Includes a fitted sheet, flat sheet, and pillowcase.
- Fitted sheet is sized for Twin XL mattresses and fits up to about 16 inches deep.
- Double-brushed microfiber has a smooth, soft feel.
- A complete set for a guest room, dorm, or everyday bed.
Cons:
- Includes only one pillowcase.
- Not the best fit for mattresses deeper than about 16 inches.
Verdict: Choose this set if you want a soft-feeling, complete Twin XL set and your mattress is no more than about 16 inches deep.
DREAMCARE: Extra-Deep Fit With a Handy Side Pocket
The DREAMCARE set includes a fitted sheet, flat sheet, and two pillowcases. Its fitted sheet is designed for mattresses up to 21 inches thick, giving it more room than the CGK Unlimited or Amazon Basics options. A corner strap helps hold the sheet in place, while the elasticized edge is intended to create a snug fit.
The fitted sheet also has a side pocket for small items such as a phone, glasses, or a book. That can be useful in a dorm room or anywhere you want bedside storage within reach. The fabric is brushed microfiber polyester, described as wrinkle- and fade-resistant, with low-temperature washing recommended.
The deeper pocket is the main reason to choose this set, but it is still important to measure your mattress, including any topper. Its maximum listed depth is 21 inches, so it may not suit especially thick mattresses. The side pocket also adds convenience, but it won’t replace a bedside table for larger items.
Pros:
- Includes two pillowcases along with the flat and fitted sheets.
- Fitted sheet is designed for mattresses up to 21 inches thick.
- Corner strap helps secure the fitted sheet.
- Side pocket keeps a few small essentials close at hand.
Cons:
- Not intended for mattresses deeper than 21 inches.
- The side pocket is useful for small items, not bulky belongings.
Verdict: This is a strong option if your Twin XL mattress is unusually deep and you want a full set with a small storage pocket.
Moonsea: A Deep Fitted Sheet Set for Tall Mattresses
Moonsea’s set is designed for a Twin XL mattress with a fitted sheet measuring 39 by 80 inches. Its extra-deep pocket is intended to fit mattresses from 16 to 24 inches deep, making it the deepest-fitting option in this group. The set includes two pillowcases, but it does not include a flat sheet.
Like the DREAMCARE option, Moonsea adds a side pocket to the fitted sheet for small items such as a phone, remote, or glasses. The fabric is brushed microfiber polyester, and the product description says it is designed to wick away heat and moisture. It can be machine washed and tumble dried on low.
This design makes the most sense if your mattress is tall and you already have a flat sheet or do not use one. The listing calls it a three-piece set, but because the flat sheet is not included, check the contents carefully before ordering. Its 16-inch minimum pocket depth may also leave excess fabric on a thinner mattress.
Pros:
- Fitted sheet is designed for mattresses 16 to 24 inches deep.
- Includes two pillowcases.
- Side pocket provides convenient storage for small bedside items.
- Machine-washable microfiber is designed for simple care.
Cons:
- Flat sheet is not included.
- The deep-pocket design may be too roomy for a thinner mattress.
Verdict: Pick Moonsea if you need a very deep Twin XL fitted sheet and are comfortable supplying your own flat sheet.
FreshCulture: A Fitted Sheet for Replacing One Piece
FreshCulture sells a single fitted sheet rather than a full set. It measures 39 by 80 inches and is designed for mattresses up to 16 inches deep. That makes it a useful choice if your fitted sheet has worn out but your flat sheet and pillowcases are still in good shape.
The sheet is made from double-brushed fabric and has elastic around all four sides to help it hug the mattress. The brand describes it as soft and breathable, and says it is machine washable in cold water. A range of color options is listed, which can make it easier to coordinate with existing bedding.
The trade-off is simple: you only receive one sheet, so this is not a complete bedding solution unless you already own the other pieces. It also has a lower maximum pocket depth than the DREAMCARE and Moonsea options, so measure before choosing it for a thick mattress or one with a topper.
Pros:
- Buy only the fitted sheet if that is the piece you need.
- Listed Twin XL size is 39 by 80 inches.
- All-around elastic is designed to keep the sheet in place.
- Available in a selection of colors.
Cons:
- Does not include a flat sheet or pillowcase.
- Designed for mattresses up to 16 inches deep.
Verdict: Choose FreshCulture when you need a replacement fitted sheet and your mattress is no more than 16 inches deep.
Amazon Basics: A Simple Easy-Care Twin XL Set
This three-piece set includes a Twin XL fitted sheet, flat sheet, and standard pillowcase. The listed sizes are 39 by 80 inches for the fitted sheet, 66 by 96 inches for the flat sheet, and 20 by 30 inches for the pillowcase. The fitted sheet has a 14-inch pocket and is described as fitting most mattresses up to 16 inches deep.
The set uses lightweight polyester microfiber, with all-around elastic on the fitted sheet. The product information lists warm machine washing and low-heat tumble drying. It also carries the MADE IN GREEN by OEKO-TEX label, which the listing describes as covering testing for harmful substances and production in safer workplaces with reduced environmental impacts.
This is a straightforward choice if you want a full set and prefer simple care. Its listed fitted-sheet pocket is shallower than the DREAMCARE and Moonsea designs, so it is less suited to a tall mattress. The single pillowcase may also be a limitation if you use two pillows.
Pros:
- Includes a fitted sheet, flat sheet, and pillowcase.
- Fitted sheet is listed as Twin XL at 39 by 80 inches.
- Microfiber is machine washable and can be tumble dried on low.
- MADE IN GREEN by OEKO-TEX certification is noted in the product details.
Cons:
- Includes only one pillowcase.
- Its 14-inch pocket is less suitable for deeper mattresses than the extra-deep options.
Verdict: Consider Amazon Basics if you want a basic, easy-care Twin XL set and have a mattress that works with its 14-inch fitted-sheet pocket.
How to Choose Sheets for an Extra-Long Twin Bed
Confirm the Mattress Length and Width
Check the label or measure your mattress before buying. The fitted sheets in these options are listed at 39 by 80 inches, so compare those dimensions with your mattress. A standard twin sheet may not be long enough for an extra-long twin bed, even if the width seems right.
Measure the Mattress Depth
Measure from the bottom edge of the mattress to the top surface, including any topper you plan to leave on the bed. The choices here range from a 14-inch fitted-sheet pocket to extra-deep designs intended for mattresses up to 21 or 24 inches. A pocket that is too shallow may pull loose; one that is much deeper than needed can leave extra fabric.
Decide Which Pieces You Need
Full sets usually include a fitted sheet, flat sheet, and one or two pillowcases. FreshCulture is a fitted sheet only, while Moonsea does not include a flat sheet. Check the package contents rather than relying only on the word “set,” especially if you want a coordinated replacement for every piece.
Choose a Fabric Feel That Suits You
All five options use microfiber, described in the product details as brushed or double-brushed. That construction is intended to give the fabric a smooth feel. If you are used to another fabric, consider whether you prefer a silky microfiber surface or want to keep using sheets made from your usual material.
Look at Fit Features and Care Instructions
All-around elastic can help a fitted sheet stay on the mattress, while a corner strap adds another way to secure it. Side pockets are handy for small items but are not essential for everyone. Also check the care directions: the listed products call for machine washing, with details such as water temperature and drying heat varying by set.
FAQs
What size fitted sheet fits an extra-long twin bed?
The fitted sheets in these products are listed at 39 by 80 inches. Check your mattress measurements and the sheet’s pocket depth before ordering, since mattress thickness can vary.
Are Twin XL sheets the same as twin sheets?
No. These products are labeled Twin XL and list fitted-sheet dimensions of 39 by 80 inches. Check the size label on your mattress and bedding before purchasing to avoid choosing a standard twin size by mistake.
How deep should the fitted-sheet pocket be?
Choose a pocket depth that matches your mattress, including any topper. For example, the Amazon Basics sheet has a 14-inch pocket, DREAMCARE is designed for mattresses up to 21 inches, and Moonsea is designed for mattresses from 16 to 24 inches deep.
Which option includes a flat sheet?
CGK Unlimited, DREAMCARE, and Amazon Basics include a flat sheet. Moonsea does not, and FreshCulture is a fitted sheet only.
Which set has the most pillowcases?
DREAMCARE and Moonsea each include two pillowcases. CGK Unlimited and Amazon Basics include one, while FreshCulture does not include pillowcases.
Do microfiber sheets need special care?
Follow the care instructions for the specific set. The product details generally call for machine washing and low-heat drying, but the exact washing directions can differ.
Final Recommendation
For a full set with extra room for a thick mattress, DREAMCARE is the most versatile choice in this group because it includes a flat sheet and two pillowcases and is designed for mattresses up to 21 inches deep. If your mattress is especially tall and you do not need a flat sheet, Moonsea offers the deepest listed pocket. For a standard-depth mattress, CGK Unlimited and Amazon Basics provide complete sets, while FreshCulture is best when you only need a replacement fitted sheet.
