where can I buy those chairs

The lounge chairs were designed by Milo Baughman in 1968. They are known as the Design Classic 989 lounge chair and still being made by their original manufacturer, Thayer Coggin. Thayer Coggin has retail partners across the US, Canada and Europe who sell these chairs: https://www.thayercoggin.com/products/989-design-classic-lounge-chair-satin-brass

And the coffee table? any pointers?

Shop for Plinth style coffee tables and you will find multiple offerings in various sizes and finishes
