The chair assembly went well except for the arms.  They took a little finesse to get them attached. We had to put the bolts in each end and leave them very loose in order to start both ends. Once each end of the arm (bolt) was started then they were tightened a little bit alternating the tightening until they were both tightened well. The assembled chair is great and I use it daily at my desk. (My wife assisted in the assembly. We followed the steps in the assembly booklet. It was easier for us because we are both retired engineers. We also have assembled all sorts of furniture throughout the past 30 years. )
