Our Picks: Best Twin Xl Sheets For Split King reviews
CGK Unlimited Split King Set: A Complete Microfiber Bedding Bundle
This set is a practical pick if you need more than fitted sheets. It includes two Twin XL fitted sheets, a flat sheet measuring 102 by 108 inches, and four pillowcases sized 20 by 40 inches. The fitted sheets are listed for mattresses up to about 16 inches deep, making the set suitable for many split-king arrangements.
The fabric is double-brushed microfiber, which the product description characterizes as lightweight, soft, breathable, and cooling. Microfiber offers a smooth feel, but it has a different texture from cotton. If you specifically want natural-fiber bedding, one of the cotton two-packs below may be a better fit.
CGK Unlimited also identifies this set as OEKO-TEX MADE IN GREEN certified. That may appeal if responsible manufacturing is part of your shopping criteria. With four pillowcases included, it is especially useful when you want extra cases or have several pillows on the bed.
Pros:
- Complete set with a flat sheet, two fitted sheets, and four pillowcases
- Fitted sheets accommodate mattresses up to about 16 inches deep
- Brushed microfiber is designed to feel lightweight and soft
- OEKO-TEX MADE IN GREEN certification is stated in the product details
Cons:
- Microfiber may not suit shoppers who prefer cotton
- The product description says “about” 16 inches, so check your mattress depth carefully
Verdict: Choose this set if you want a full split-king bedding bundle with extra pillowcases and a soft microfiber feel.
Shunjie.Home Cotton 2-Pack: Breathable Twin XL Fitted Sheets
This two-pack is focused on the part of a split king that needs to fit each mattress separately: the fitted sheets. Each sheet measures 39 by 80 inches, the standard Twin XL dimensions listed in the product details, and has a 16-inch pocket. The package contains two fitted sheets, not a flat sheet or pillowcases.
The fabric is described as 100% pure cotton made from organic long-staple cotton, with a 600 thread count and sateen weave. The brand presents the material as cool and breathable, with a smooth feel. Cotton is a natural-fiber alternative to the microfiber sets in this lineup, though the hand-feel of a sateen weave may differ from a crisp percale cotton sheet.
For everyday use, the all-around elastic and “FOOT” tag are practical details: elastic is intended to hold the sheet in place, while the tag helps identify the correct direction when making the bed. The care instructions call for machine washing on a gentle, cold cycle and tumble drying on low.
Pros:
- Two separate Twin XL fitted sheets for a split king
- 100% cotton fabric with a sateen weave
- 16-inch pockets and elastic around the sheet
- Foot tag helps with orientation during bed-making
Cons:
- Does not include a flat sheet or pillowcases
- Limited to the beige color listed in the product title
Verdict: Pick this two-pack if you want cotton fitted sheets only and already have a flat sheet and pillowcases.
P Pothuiny Split King Set: Microfiber Bedding with Two Pillowcases
This five-piece set includes a 108 by 102 inch flat sheet, two Twin XL fitted sheets, and two envelope-style pillowcases measuring 20 by 40 inches. Each fitted sheet is listed at 39 by 80 inches with a pocket for mattresses up to 16 inches deep. That split layout lets each side of an adjustable bed move independently.
The sheets are made from brushed microfiber. The product description presents the fabric as lightweight and breathable, with a soft feel intended for use across seasons. Reinforced all-around elastic is designed to help the fitted sheets stay on the mattresses as the adjustable bases move.
Compared with the CGK Unlimited set, this option includes fewer pillowcases but still provides a flat sheet and both fitted sheets. Its teal color may be a useful choice if you want bedding with more color than the white or beige options elsewhere in this list. As with other microfiber choices, it may not be the right match if you favor cotton.
Pros:
- Includes the flat sheet and two fitted sheets needed for a split king
- Comes with two envelope-style pillowcases
- Fitted sheets have reinforced elastic and pockets up to 16 inches
- Teal color provides an alternative to neutral shades
Cons:
- Includes fewer pillowcases than the CGK Unlimited set
- Microfiber will not provide the feel of cotton bedding
Verdict: Consider this set if you want a coordinated microfiber bundle with a flat sheet, two fitted sheets, and two pillowcases.
Shunjie.Home Egyptian Cotton 2-Pack: Cotton Fitted Sheets for Adjustable Beds
This white two-pack contains two Twin XL fitted sheets, each measuring 39 by 80 inches with a 16-inch pocket. Like the other fitted-sheet-only option, it is meant for shoppers who already have a flat sheet and pillowcases or want to choose those separately.
The product details describe the fabric as 100% Egyptian cotton with a 600 thread count and a satin process. The sheets are also described as OEKO-TEX certified. A 360-degree elastic edge is intended to hold each sheet on the mattress, while the listed pocket depth makes it important to compare the sheet with your mattress and any topper.
Its main distinction from the beige Shunjie.Home cotton two-pack is the stated Egyptian cotton fabric and white color. Both are cotton options with 16-inch pockets, so the choice comes down to the listed material, color, and your preference. The brand describes these sheets as durable and resistant to common wear, but proper care is still important; follow the product’s care guidance when available.
Pros:
- Two Twin XL fitted sheets for a split-king setup
- 100% Egyptian cotton with a 600 thread count, as described by the brand
- 16-inch pockets and elastic around the full edge
- OEKO-TEX certification is stated in the product details
Cons:
- Does not include a flat sheet or pillowcases
- Only the white color is specified in the product title
Verdict: Choose this two-pack if you want white Egyptian cotton fitted sheets and do not need the rest of a sheet set.
How to Choose Twin XL Sheets for a Split King
Confirm the Mattress Size
A split king typically uses two separate Twin XL mattresses, so each fitted sheet needs to match one mattress rather than cover the full bed. The options here list fitted sheets measuring 39 by 80 inches. Check the dimensions of your own mattresses before ordering, especially if they are a nonstandard size.
Measure Mattress Depth
Fitted-sheet pocket depth matters because a mattress that is too deep can pull the corners loose, while a very deep pocket on a thinner mattress may not fit as snugly. The products in this roundup list pockets of 16 inches or up to about 16 inches. Measure from the mattress base to the top of the mattress, including any topper you keep on the bed, and compare that total with the listed pocket depth.
Choose a Full Set or Fitted-Sheet Pair
The CGK Unlimited and P Pothuiny options include a flat sheet and two fitted sheets, along with pillowcases. The Shunjie.Home products include two fitted sheets only. A fitted-sheet pair can be a sensible choice if you already own the other pieces or want to mix colors and fabrics; a complete set is more convenient if you are replacing most of your bedding at once.
Decide Between Cotton and Microfiber
The microfiber options are described as soft, lightweight, and breathable. The cotton options offer a natural-fiber alternative, and both Shunjie.Home listings specify a 600 thread count. Fabric feel is personal, so consider what you already like sleeping on rather than relying on thread count alone. The cotton products use different descriptions—one identifies long-staple cotton and a sateen weave, while the other identifies Egyptian cotton and a satin process.
Check How the Sheets Will Work with an Adjustable Base
With a split king, the two fitted sheets cover separate mattresses, allowing each side to move on its own. Features such as all-around elastic or reinforced elastic are intended to help keep sheets in place. If you adjust the bed often, pay close attention to a secure fit and make sure the pocket depth suits your mattress setup.
Consider Care and Color
The cotton two-pack in beige lists machine washing on a gentle, cold cycle and tumble drying on low. For other options, check the package or product listing for complete care instructions before washing. Color also affects how easily a set coordinates with your existing bedding: this selection includes white, beige, and teal options.
Frequently Asked Questions
Do split-king beds need Twin XL sheets?
Most split-king setups use two separate Twin XL mattresses, so each side needs its own Twin XL fitted sheet. Check your mattress measurements to confirm that the 39-by-80-inch dimensions match your bed.
Can I use regular king sheets on a split king?
A regular king fitted sheet is designed to cover one continuous mattress and may not fit two mattresses that move independently. For a split king, use separate fitted sheets made for each side. A king-size flat sheet may be used across the bed if its dimensions suit your setup.
Do these products include two fitted sheets?
Yes. All four options list two fitted sheets. The CGK Unlimited and P Pothuiny products also include a flat sheet and pillowcases, while both Shunjie.Home products are two-packs of fitted sheets only.
Will a 16-inch pocket fit my mattress?
It may, but measure the full depth of your mattress and any topper first. Three products list a 16-inch pocket, while the CGK Unlimited set says it fits mattresses up to about 16 inches deep.
Which options are made of cotton?
The two Shunjie.Home fitted-sheet pairs are listed as cotton. One is described as 100% pure cotton made from organic long-staple cotton; the other is described as 100% Egyptian cotton. The CGK Unlimited and P Pothuiny sets are made from brushed microfiber.
Which set is best if I need pillowcases and a flat sheet?
The CGK Unlimited set includes a flat sheet, two fitted sheets, and four pillowcases. The P Pothuiny set includes a flat sheet, two fitted sheets, and two pillowcases. The Shunjie.Home options include fitted sheets only.
Final Recommendation
For a complete split-king bundle, the CGK Unlimited set stands out for its two fitted sheets, flat sheet, and four pillowcases. If you want cotton and only need fitted sheets, compare the two Shunjie.Home pairs based on their listed fabric descriptions and color. The P Pothuiny set is another complete option, with two pillowcases and a teal microfiber finish. Before choosing, measure both mattresses and any toppers to confirm the 16-inch pocket depth will work for your bed.
