Compatibility & requirements

Choose this set for a Twin XL mattress measuring 39 x 80 inches. The fitted sheet’s all-around elastic is designed for a close fit, and its pocket accommodates mattresses 8 to 15 inches deep. Headside and footside indicator tags show how to orient the fitted sheet, which is useful when making the bed or changing sheets. The pillowcase is sized to fit either a standard or queen pillow. If you are comparing a coordinated set with buying bedding pieces separately, this option groups the flat sheet, fitted sheet, and pillowcase in one matching stripe print.

How to use it

Place the fitted sheet over the mattress, using the indicator tags to position the head and foot ends. The elastic runs all around the sheet to help keep it in place. Layer the flat sheet over the bed and use the included pillowcase for a standard or queen pillow. For everyday upkeep, machine wash and tumble dry at regular settings. The fabric has been tested for shrinkage, pilling, and fading, making its care details practical to consider as part of a regular bedding routine.
