A rare and beautifully shaped lounge sofa made by van Os Culemborg, The Netherlands. Designed by G. van Os during the 50s. This sofa has nicely shaped armrest and a beautifully curved frame. The sofa has new foam and new fabric. 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
