What could cause a drawer in a bedside table to become stuck?
If the drawers have the more modern full extension ball bearing slides it is possible for the slider intermediate rail to get aligned to one end opposite it's normal operating position. This can cause the drawer to either not pull out all the way or not close all the way when you push/pull the drawer with gentle force. A higher force will cause the intermediate rail to slide on its balls instead of rolling thus getting the piece into it's proper position.
