A refrigerator comprising a vacuum insulated structure, wherein the vacuum insulated structure comprises: a first cover member of a stamped unitary sheet defining a perimeter portion (66, 68) positioned at a first planar level and a deformation control member (82, 84) formed in the unitary sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion (66, 68); a second cover member; and a thermal bridge interconnecting the first cover member and the second cover member at the perimeter portions (66, 68) thereof to define an insulating cavity therebetween, wherein the insulating cavity is a sealed cavity having a vacuum drawn therefrom, and further wherein the first deformation control member is configured as a first rib defining an open interior portion extending axially outward of an inner surface of the first cover member, thereby reducing deformation of the first cover member in at least an area adjacent the deformation control member and to define a portion of a path for air flow out of the sealed cavity during a vacuum draw process, characterised in that: the first cover member is a unitary structural portion of an outer wrapper of the refrigerator that defines a rear wall, a top wall, and a bottom wall of the outer wrapper, wherein the second cover member defines a stepped area defined by a stepped segment of the second cover member within at least one of the rear wall and the top wall, the stepped area being a first stepped area, and the first cover member defining a second stepped area within the top wall of the unitary structural portion; the second cover member is a side wall (58, 60) of the outer wrapper of the refrigerator, the second cover member being coupled to the first cover member along bottom, rear, and side edges (68a, 68b, 68c) of the perimeter portion (66, 68); and the thermal bridge interconnects the first cover member and the second cover member between a front edge of the first cover member and both a top-front edge and a bottom-front edge of the second cover member. a first cover member of a stamped unitary sheet defining a perimeter portion (66, 68) positioned at a first planar level and a deformation control member (82, 84) formed in the unitary sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion (66, 68);
