This classic Itlalian club chair model 'M538', designed by Studio APA for Lenzi, is a distinguished piece of mid-century modern furniture from the 1960s. Renowned for its sculptural form and exceptional comfort, this lounge chair exemplifies this era's design style. 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
