Solid armchairs by UP Zavody made in 1930s. Heavy and sturdy construction. Very well preserved fabric, only minor sun fading on one chair. Inner filling is soft after one hundred years but still comfortable. Suitable for new upholstery. 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
