Set of 4 vintage High Ingram chairs (1980s)

Beautiful set of 4 High Ingram 3014 by Charles R. Mackintosh from 1984 by MDF Italia. Masters of the 20th century collection. Chairs made of open pore black lacquered ash wood. Soft cushion in pink-salmon-colored textured cotton fabric with weave. They are almost 40 years old. In excellent state of conservation. The wooden structure is ok, no rips or holes. There are very small dots on the fabric on 2 seats. Well-kept artifacts, as shown. Minimal signs of use. There are small and normal wear points on the wooden parts, near the corners. Not particularly obvious. They have the peculiarity that 2 chairs have a seat height of 46 cm, and two of 43 cm
