A vacuum insulated cabinet structure includes first and second cover members having pre-deformed portions and perimeter portions. The perimeter portions of the first and second cover members are disposed along first and second planar levels and the pre-deformed portions of the first and second cover members include portions thereof extending outwardly relative to the first and second planar levels. A thermal bridge interconnects the first cover member and the second cover member at the perimeter portions thereof to define an insulating cavity therebetween. The insulating cavity is a sealed cavity having a vacuum drawn therefrom. The pre-deformed portions of the first and second cover members move inwardly towards the first and second planar levels under a force of the vacuum within the insulating cavity.
