As with all products found on the internet there are some risks associated with purchasing your Eurotech Ergohuman online. The best way to eliminate the majority of these risks is to make your purchase with an Authorized Ergohuman Chair Dealer that has a history of strong customer service and good business relations. You may be asking, "how do I know if the authorized dealer is reputable?" This is what we are here for. Make sure that the website you are buying from has some type of reliability or satisfactory customer rating seal. A good example of this is the Better Business Bureau Online Reliability Program. These types of seals can usually be found on the website's footer or often on the left or right task bar. We also caution all buyers to beware of auction sites such as eBay. The sellers found on eBay are almost always unauthorized resellers. The danger in buying from unauthorized resellers is that you have no idea how old the Eurotech Ergohuman is and you can't be absolutely positive that it is new if they say it is new. The biggest reason to avoid unauthorized resellers is that they will not be able to issue the lifetime limited warranty offered by all Authorized Dealers of Eurotech Seating Products.
