The "Tentazione" chair (model 684) by Mario Bellini for Cassina was designed in the 1970s. Rounded contours of white leather around a steel frame. Can be used as an armchair or dining room chair. The chairs do no longer have any marking, hence only attribute them to Bellini. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
