My office chair, which I am very comfortable in, has served me well. However, over the years has started to wear out. First the cloth arm rest cushions. These I ended recovering using the leather from an old black leather jacket I no longer needed. Then, more recently, the chair would not stay elevated because the pneumatic piston that holds the height, developed a leak through one of its seals. This, in itself would have been enough to get rid of the chair, had I not found EChairParts.com. They were helpful in determining what replacement gas cylinder I would need to order. Installing the replacement gas cylinder was easy and straight forward. I’m just pleased to know that a company such as this exists and will sell to the consumer. These days, far too many products, that can be fixed simply get thrown away.
