Query: Worst. Machining. Ever.

This is absolutely the worst machining I have ever seen on a chair. What usually would be a fairly simple 20 min. assembly turned into a two hour long struggle trying to force screws into holes that are literally drilled at varying angles and degrees. I gave it three stars for being as comfortable as any comparably priced computer chair and negative two stars for being the most awful thing I have ever had the displeasure of assembling.
