Pair of chrome and leather "Libellula" chairs

Pair of chrome metal chairs with white dyed leather seat and backrest secured by a spring system for added seating comfort. The chair is named Libellula for its light and airy design. The designer is Giovanni Carini, manufactured by the Italian company Planula. They date from the 1970s-80s, in used condition, with a beautiful patina on the leather, a slight tear (see photos), and some oxidation on the chrome.
