This chair was designed by Jorgen Rasmussen For Rabami. This is essentially an 1980s update of the 50s 'Kevi' chair. Same designer, different manufacturer. According to some sources this chair was distributed in the US by the Herman Miller company. Although this type of chair is now ubiquitous, it has its origins in Danish design. Of course right?
I had two of these chairs. The red one pictured needs a fix to its seat height adjuster and is offered for $100.
