Yes—there are sheets made for adjustable beds, and the right style depends on how your mattress moves. A split-head, or flex-top, king has a split near the head so each side can rise independently; a split king has two separate mattresses that move independently along their full length. Look for sheets labeled for your bed’s exact setup, plus a fitted sheet with deep pockets and secure elastic. Here are three options to compare, along with the fit details to check before you buy.

Best for Split-Head Beds: Sweet Home Collection Flex Top King Sheets
This four-piece set is designed for a split-head, or flex-top, king mattress. That layout lets the head sections move independently while the lower part of the bed stays joined. A standard fitted sheet may pull at the split when the bed moves, so a fitted sheet made for this mattress style can make a better match.
The set includes a deep-pocket fitted sheet with built-in corner straps. These features are intended to help keep the sheet in place as the adjustable base changes position. The brand describes the fabric as silky-soft, breathable, wrinkle-resistant, and easy to care for. Those are useful qualities for everyday bedding, though your comfort will depend on your own fabric preferences.
Compared with the Ready To Rest option below, this set does not provide a specific maximum mattress depth or split measurement in the supplied details. Check your bed’s dimensions and the current listing before ordering. It is also a four-piece set, so it may be less suitable if you want extra pillowcases included.
Pros:
- Made for split-head and flex-top king beds
- Built-in corner straps help limit shifting
- Deep-pocket design accommodates a mattress and topper
- Four-piece set includes the core bedding pieces
Cons:
- The supplied details do not specify the maximum mattress depth
- Includes fewer pieces than the seven-piece set below
Verdict: Choose this set if you have a split-head king and want fitted-sheet straps, but confirm the pocket depth and set contents suit your mattress and needs.
Best Seven-Piece Set: Sweet Home Collection Split King Sheets
This set is presented as a split king option and comes with seven pieces: a fitted sheet, a flat sheet, and four pillowcases for king sizes. Twin and Twin XL versions include two pillowcases instead, so check the selected size and package details before you order.
Its main practical feature is built-in elastic at the corners, designed to help hold the fitted sheet on an adjustable mattress. The product description also specifies extra-deep pockets and thick elastic, which may be useful if your mattress is tall or has a topper. The fabric is described as part of a 1500 Supreme Deluxe collection, but the supplied details do not name its fiber content.
This is the most complete set in the comparison for shoppers who want several pillowcases included. However, the listing information provided does not give an exact pocket depth or explain whether the fitted sheet is split at the head, separated along the full length, or offered in multiple configurations. Confirm that the size and sheet layout match your particular adjustable bed before purchasing.
Pros:
- Seven-piece set includes four pillowcases in king size
- Built-in elastic corners are designed to secure the fitted sheet
- Described as having extra-deep pockets and thick elastic
- Machine-wash and low-heat tumble-dry care instructions are provided
Cons:
- The supplied details do not state an exact pocket depth
- Confirm the fitted-sheet configuration for your specific split-bed layout
Verdict: This is a good option to consider if you want a fuller sheet set, but verify both the selected size and the split configuration before adding it to your cart.
Best Specified Fit for Flex-Top Beds: Ready To Rest Split Top King Sheets
Ready To Rest makes this four-piece set specifically for split-head, or flex-top, king beds. The fitted sheet has a 34-inch split at the top, a useful measurement to compare with your mattress before buying. The stated set includes a fitted sheet, flat sheet, and two king-size pillowcases.
The fitted sheet is listed for mattresses from 12 to 16 inches thick. That range makes this option easier to assess if you know your mattress depth. The fabric is described as brushed microfiber with a 1800 thread count, and the product information highlights breathability, wrinkle resistance, and machine washing.
Its clear split and depth specifications are helpful points of comparison against the other options here. On the other hand, the stated fit range starts at 12 inches, so shoppers with a thinner mattress should check the listing for compatibility. The set also includes two pillowcases, rather than the four provided with the king-size version of the seven-piece Sweet Home Collection set.
Pros:
- Designed for flex-top king beds, including beds described as Number beds
- Specifies a 34-inch top split
- Fitted sheet is listed for mattresses 12 to 16 inches thick
- Four-piece set has clearly stated sheet and pillowcase dimensions
Cons:
- Listed fit range may not suit mattresses thinner than 12 inches
- Includes two pillowcases rather than four
Verdict: Pick this set if your bed is a flex-top king and its 34-inch split and 12-to-16-inch mattress range match your measurements.
How to Choose Sheets for an Adjustable Bed
Identify Your Bed’s Split Style
Start by checking whether your bed is a split-head king or a split king. A split-head mattress has a division near the head, while a split king uses two separate mattresses that can move independently. These layouts need different fitted-sheet configurations. The phrase “adjustable bed sheets” alone may not tell you which one will fit, so check your mattress or base manual and compare it with the product listing.
Measure the Mattress and Topper Together
Measure the mattress from side to side and head to foot, then check its depth with any topper you plan to keep on the bed. A pocket that is too shallow can make the fitted sheet pull loose; a pocket that is much too deep may not hold as neatly. Compare your measurements with the product’s stated pocket depth or mattress-depth range. If no range is listed, look for confirmation from the seller before ordering.
Check the Split Measurement
For a flex-top bed, the length of the split matters. A sheet split that does not match your mattress can bunch, pull, or restrict movement near the head. The Ready To Rest set, for example, specifies a 34-inch top split. Measure your mattress’s split and compare it with the listing rather than assuming all flex-top designs are alike.
Look for Features That Help the Sheet Stay Put
Adjustable bases change the angle of the mattress, which can tug on bedding. Deep pockets, full elastic around the fitted-sheet edge, and corner straps or built-in elastic corners can help keep a fitted sheet secure. These features are not a substitute for choosing the correct size, so treat them as added support rather than a fix for an incompatible sheet.
Choose Fabric and Care That Suit You
Fabric affects how sheets feel, breathe, and fit into your laundry routine. The options here are described with features such as microfiber, softness, breathability, and wrinkle resistance, but your preferred feel is personal. Check the product details for fiber content and washing instructions if those matter to you. For example, the seven-piece set specifies machine washing in cold water and tumble drying on low.
Compare the Full Set Contents
Count the pieces you will actually use. A four-piece set may include the fitted sheet, flat sheet, and two pillowcases, while a larger set may include extra pillowcases. Also confirm that the listed size is the one you need; pillowcase counts can differ by size. A larger piece count does not necessarily mean a better fit for your adjustable bed.
Frequently Asked Questions
Are there special sheets for adjustable beds?
Yes. Some sheet sets are made for flex-top or split mattresses, and many use deep pockets, elastic edges, or straps to help the fitted sheet stay in place as the bed moves. The key is matching the sheet’s split style and dimensions to your mattress.
Can I use regular sheets on an adjustable bed?
You may be able to use regular sheets if they fit securely and allow the mattress to move without pulling loose. Sheets made for your specific split style, with a suitable pocket depth and secure elastic, can be a more suitable choice for beds that move often.
What is the difference between a split king and a split-head king?
A split king usually has two separate mattresses that move independently along their full length. A split-head king has a split near the head while the lower portion remains joined. Check which style you have before choosing fitted sheets.
How do I know what pocket depth I need?
Measure the mattress thickness and include any topper that will stay on the bed. Then compare that total with the sheet’s stated pocket depth or mattress-depth range. If the listing does not provide a clear range, confirm fit before ordering.
Do sheet straps stop fitted sheets from slipping?
Straps and built-in elastic corners are designed to help hold a fitted sheet in place. They may reduce shifting, but they cannot make an incorrectly sized or incompatible sheet fit properly.
Do split-top sheets work with every adjustable king bed?
No. Split-top designs can have different split lengths, and some king beds are split along the full length instead. Compare the sheet’s stated split measurement and mattress dimensions with your bed before buying.
Final Recommendation
Special sheets can make an adjustable bed easier to keep made, but the right fit depends on your mattress layout and measurements. The Ready To Rest set is the clearest option for shoppers who want a stated 34-inch split and a 12-to-16-inch mattress range. The first Sweet Home Collection set is designed for split-head king beds and includes built-in corner straps, while its pocket depth should be confirmed. If you want extra pillowcases, consider the seven-piece set after verifying its exact split configuration and size.
