The materials and sturdiness of the chair is fine. However, putting it together takes two people and well into two hours. Trying to use a hex wrench and an allan wrench at the same time to tighten something is infuriating. If you are going to advertise 10-15 minutes and you have a chair then it shouldn't come in pieces A-M and 30 screws, nuts, bolts, wrenches, and screwdrivers. My husband and I were both sweating and cursing by the end of assembly.
