Deep Pocket Fitted Sheet for Thick Mattresses
MildMate Deep Pocket Fitted Sheet is designed for thick mattresses, pillow-top beds, mattress toppers, adjustable beds, and extra-deep setups. Each sheet is made to your selected size and confirmed dimensions to help the fit stay smooth and secure.
Standard Construction (Default)
- Fits mattress depth up to 20 in / 51 cm
- Finished pocket depth approximately 22 in / 56 cm
- Under-tuck allowance approximately 2 in / 5 cm
- 360° full-perimeter elastic
Important: the standard 22 in / 56 cm finished pocket includes under-tuck fabric below the mattress edge. It should not be marketed as a default fit for a 22-inch-thick mattress.
Pocket Depth Formula
Confirmed mattress depth + approximately 2 in / 5 cm under-tuck = finished pocket depth
