Measurement method

Start with the product and space you actually have.

1
Measure the mattress. Record width, length, and full depth without relying on the label.
2
Add every layer. Toppers and pads change fitted-sheet pocket needs.
3
Choose coverage. Decide the side drop, foot drop, top alignment, and any tuck.
4
Read finished dimensions. Compare your target with the actual product specification.

Calculate a target size for your own mattressUse your measurements instead of relying on a nominal label.
