1. A vehicle interior system comprising
a base having a curved surface;
a cold-formed glass substrate disposed on the curved surface, the glass substrate comprising a first major surface, a second major surface opposing the first major surface and facing the curved surface, and a minor surface connecting the first major surface and the second major surface, a thickness defined as a distance between the first major surface and the second major surface, a width defined as a first dimension of one of the first or second major surfaces orthogonal to the thickness, and a length defined as a second dimension of one of the first or second major surfaces orthogonal to both the thickness and the width;
an adhesive disposed between the curved surface and the glass substrate; and
at least one stress-reduction component in a location that reduces an amount of adhesive stress in one or more areas of the adhesive;
wherein the thickness is 1.5 mm or less, the width is in a range from about 5 cm to about 250 cm, and the length is from about 5 cm to about 250 cm
wherein the at least one stress-reduction component comprises one of an area of the curved surface comprising a radius of curvature that is larger than that of another area of the curved surface and a hot-formed area of the cold-formed glass substrate, and
wherein the second major surface comprises a first radius of curvature of 500 mm or greater.
