This is a Knoll Handkerchief Chair by Lella and Massimo Vignelli in Red, introduced in 1983. The price listed is for each chair. These chairs are very resilient, and stackable with a generous seat size and the organic lines suggestive of a handkerchief in the wind. These examples are in very good condition, with some signs of regular wear over the years. See photos.

Each chair measures 29.5 inches tall by 23 inches wide and 22.5 inches deep. As noted, the price listed is for one chair. Multiple chairs are available.
