Abstract: A refrigerator has a shelf seating protrusion and a separate shelf seating member. The shelf seating protrusion is not formed at an approximate mid-point, height wise, of a storage space defined by an inner casing. The shelf seating member may be coupled to the inner casing to support a shelf assembly. An arrangement of the shelf seating protrusions and the shelf seating member is configured to reduce deformation and cracking of the inner casing due to thermal impact in a manufacturing process or when items are stored on the shelf assembly.
