Replacing Saarinen seat cushions  

Am in need of new seat cushions for 4 of my Knoll Saarinen tulip arm chairs. Seems no one appreciates the wonderful wear and tear in the original ones that are on them 🙁 and think I'm some eccentric middle age crazy who gave up a perfectly beautiful kitchen dinette set for something they see no value in (poor souls). Checking around I find just a few places that carry true Knoll Saarinen replacement cushions at a dear price of just under $300 a piece!!! I'm sure I can have someone make cushions for a lot less but I would like to keep true to the original. Am I stuck with buying expensive originals or is there someplace I can get them for a bit less? (Breaking the bank!!!) ~Elle
