Four small armchair

These are vintage armchairs with a minimalist design, typical of Italian or Northern European production between the late 1960s and early 1970s.
Here's a detailed description:
• Frame: Bent chromed steel rod sled base, lightweight and stackable.
• Seat and backrest: Padded and upholstered in burnt orange fabric (typical of 1970s colors), with ergonomic shapes and rounded edges.
• Armrests: Upholstered in the same fabric, attached to a metal support integrated into the frame.
• Style: Sober and functional, reminiscent of rationalist design and office or conference room products of the era.
