Split-King Bedding Planner
Plan fitted sheets for two separate mattresses, shared or separate flat sheets, and the pillowcases you actually need.
Separate fitted-sheet requirements, shared/separate top-layer decisions, case count and an explicit Twin XL catalog boundary.
How this works
Model each mattress’s measured width, length and covered depth independently. With head ends aligned and no gap, combined width = leftWidth + rightWidth and bounding length = max(leftLength, rightLength); report any length difference rather than creating an imaginary single mattress. Two conventional Twin XL mattresses are 38 × 80 inches each, totaling 76 × 80. Independent adjustment requires separate fitted-sheet decisions even when the total resembles King. Shared flat-sheet preference is one top sheet with enough actual width, head allocation and tuck; separate preference is two measured flat sheets. Pillowcase count is the entered pillow count, with actual pillow dimensions. Nominal matches identify references only; the current Abeero Home catalog has no Twin XL fitted-sheet match.
Combined geometry is not a recommendation for a one-piece King fitted sheet. No unsupported Twin XL alternative is substituted.

Common questions
What sheets do I need for two independently adjustable Twin XL beds?
Plan one correctly specified fitted sheet per 38 × 80-inch mattress, checking each covered depth. Choose one shared or two separate flat sheets by preference, then cases for your actual pillows. Abeero Home currently has no Twin XL fitted-sheet option.
Can two regular Twin sheets substitute for Twin XL?
No substitution is recommended. Conventional Twin is 38 × 75 inches; Twin XL is 38 × 80. The five-inch length difference matters independently of the combined width.
Can I use one King fitted sheet because the total is 76 by 80?
Do not assume that. Independent movement and two separate mattresses need separate fit decisions; a one-piece King fitted sheet is not promised to work. Seek explicit product/base manufacturer support.
Should the top sheet be shared or separate?
That is a preference. A shared sheet needs fabric for the combined span and desired tuck and may move with either half; separate sheets give each side its own fabric allocation. Actual flat-sheet measurements decide coverage.
Are the mattresses required to be identical?
No. Enter each side independently. The result reports unequal lengths and depths rather than forcing both mattresses into a Twin XL reference.
How many pillowcases come with the plan?
The required count is your entered pillow count, not an invented set quantity. Included cases are exact-variant facts and may not match your pillows; use the pillowcase checker.
