Ebay.com, SeatingConcepts.com, and Amazon.com are three online retailers which sell parts for True Seating Concept chairs. Echairparts.com also sells generic chair parts that may be compatible with a True Seating Concepts chair.
In late 2015, eBay.com had the most choices and selection of parts, by several hundred, compared to other retailers. Amazon.com listed about a dozen parts, and SeatingConcepts.com listed contact phone numbers to inquire about which parts were available. Echairparts.com listed many dozens of various parts by category, as well as combination part kits and miscellaneous hardware items.
TrueInnovations.com is the parent company for True Seating Concepts chair products, but sells products to retailers and not directly to the public, according to its website.
