I give them a plus for quality materials however they all have a wobble after assembling. Instructions we're okay but were not a detailed step by step. I tried different tactics within each step to include having someone sit in the chair before tightening all fasteners. Still no luck in getting a fully assembled chair without a wobble. Considering the number of parts that make up the chair I'm not really surprised. Assembly wasn't difficult, however, it took more time than I thought it would. Next time, I would buy a fully assembled chair with welded joints and pay the extra cost. The low price point was not worth my time nor the eventual post-assembly wobble.
