They were purchased from IKEA several years ago but are no longer available. We really like these chairs and have used them on several projects- good price, very comfortable, have held up well over the years. You might check with IKEA in the spring to see if they have restocked them.

These chairs look similar to some of the reading area chairs at the newly opened central San Diego Public Library. Maybe you can check with the architects/designers? http://www.sandiego.gov/public-library/about-the-library/projects/newcentral.shtml#details
