Why Pocket Depth Matters More Than You Think
If your fitted sheet constantly slips off or feels loose and messy, the problem is usually not the size—it’s the pocket depth.
Many shoppers choose between “deep” and “extra deep” without knowing the difference, which often leads to:
sheets popping off at night
excess fabric bunching up
uncomfortable sleep
👉 The right pocket depth ensures your sheet stays snug, smooth, and sec
