These are terrible chairs, of very low quality.  First, it was very difficult to assemble due to the poor manufacturing craftsmanship.  Secondly, the chairs are very flimsy, indicating they were made out of cheap wood.  Third, the chair can only swivel when you sit in it.  Otherwise, because it is so flimsy, the whole chair just turns whenever you try to move the back.  Then, two days after they were assembled, the wood on one of the legs split into two, rendering the chair totally non-functional.
