You have two options when you want to get a Ikea assembly in Vienna service. One is to have it assembled in the Ikea store but you have to purchase a delivery. The delivery cost starts at $89 and is based on the price of the product that you purchased but is not inclusive of tax. This delivery charge can fluctuate depending on your location or state. For instance, if you purchase a $89 delivery service, your assembly price for your flat-packed furniture would be around $1000 to $299. A $159 delivery service can cost your Ikea assembly in Vienna around $300 to $599. A $259 delivery will entitle you to a $600 to $999 assembly fee for your furniture. The price just goes on and on. The higher your delivery cost means the higher your assembly fee. If you think that Ikea is the one who assembles your furniture, you are wrong. The assembly is done by one of their partner companies. The delivery is from a separate delivery entity as well. That explains the high cost of their assembly services.
