Pair of 70's shell chairs, swivel, vintage

Pair of swivel chairs from the 70s in fabric, with chrome legs. Please note, there are stains on the fabric, side dents in the shells (where they meet the table), and one chair has a dent at the seat level, which is not visible once the seat cushion is placed. Everything is visible in the detailed photos, and the price reflects these defects. Dimensions: height 80.5 cm, width 55.5 cm, depth 54 cm, seat height 49 cm.
