If your Mom has to use a step stool to be able to get into bed something needs to be done because this is an extreme fall risk!
While you could cut off the legs of the bed to get the mattress closer to the floor, a better solution might be to replace the box spring with a Bunkie Board.
Bunkie Boards are only a couple of inches thick and can get the mattress approximately 6 inches closer to the floor. And, make it a whole lot safer for Mom or Dad to get in and out of bed! Amazon carries Bunkie Boards and the prices are reasonable, under $100.
