I bought this for my chair seat to be replaced. Unfortunately the chair maufacturer, Okamura does not provide the seat for replacement. I don't know why they don't but every users who own want ot replace the seat to new one from worn seat. Anyway I tried to find appropreate materials for it and finally I found your product. Your product is enough hard, sturdy and seems to be duable. I'm satisfied with this and fast shipping as well.
