A flexible ring mold for shaping heat softened glass sheets is provided with an inner ring having a plurality of posts which help support the ring mold and maintain the mold's generally planar configuration during the initial lifting and shaping of a supported glass sheet. Prior to the entire glass sheet being pressed against an upper mold surface, the ring mold is separated from the support posts.
