Set sofa banquet armchairs 1974

Untraceable set of two armchairs and a sofa (2 seats) bucket from 1974. They are unique because they are made exclusively and artisanally for the showroom of a publishing house. Chrome base, fiberglass shell and Alcantara cover. The covers can be dismantled very simply (zipper) for dry cleaning (which has just been done). Very good condition, perfect seat without sagging. Both chairs swivel on themselves. Here are all the dimensions: Armchairs. Height at the backsplash 94cm. Seat height 40cm. Width 74cm. Depth 90cm. Sofa. Height at the backsplash 97cm. Seat height 40cm. Width 150cm. Depth 90cm. Attention, if delivery by me, the whole can not be mounted upstairs, thank you.
