The frame of the laundry separated is made of cast iron and coated with a metallic paint, providing excellent rust resistance. It is also equipped with 6 horizontal bars, with 3 at the bottom, which makes the laundry cart more stable and effectively prevents the laundry bags from sagging. The unique frame design can prevent the wheels from soiling the walls, keeping the room clean and tidy.The laundry rolling cart is equipped with heavy-duty casters, which can smoothly transport the laundry sorter to the laundry room. The foam handle ensures anti-slip during use. There are four 360° swivel wheels at the bottom (two of which can be locked).
