Spare parts for Ikea armchair Lillberg wanted

I have been an absolute fan of Ikea for many, many years. My favorite piece is a Lillberg armchair. Recently, I moved and to my dismay, the screws and the long "Metalldinger, die den Sessel zusammenhalten" have been lost. The IKEA store couldn't help me and neither did my email to IKEA, since the Lillberg series is no longer being produced. Can someone help me? I want to be able to use my beloved armchair for a long time and would be very sad if I had to throw it away because of the missing spare parts. Thank you very much! Elisabeth

The long "metal things" are cross captive bolts (available in a short version with one hole or longer versions with double holes) - see e.g.

scheulenburg-direkt.de/Media/pdf/08_Quermutterbolzen.pdf

maybe Ikea can do something with this name?
