Got two of these chairs. You need to attach seat with swiwel to legs. Should be a two minute exercise. In our case, swiwel was so stiff, we could not turn it. Googled manufacturer in Washington. Called them up and they patiently and kindly explained how to solve problem. (Place a towel on floor, put chair top on towel, sit on it and swiwel loosens)
Otherwise, great looking chairs delivered at an unbeatable price
