This Lounge chair by Hans Eichenberger has a high quality chrome plated tubular base and a two tone brown leather adjustable seat and back. The chair has a Bauhaus style design with a nice modern touch. The brown color of the seat contrast really nicely to the stitched tick Cognac Color leather and the frame. It remains in good vintage condition with wear consistent with age and use, preserving a beautiful patina, it has no damages. 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 have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
