Set of 2 lounge chairs by Rudolf Wolf

This set of two rare lounge chairs was designed by Rudolf Wolf and produced by Elsrijk in the Netherlands in the 1950s. This minimalist yet comfortable set of early industrial chairs has a distinct metal frame and a striking blue color. The fabric of both chairs shows some small signs of wear on the upper corners of the backrest. There is also a steel tube with scribbled letters on it, but overall the set is in good vintage condition, as shown in the photos. Both chairs are marked Elsrijk underneath.
