Just put together some of the pieces wouldn’t line up. Still trying to line up the bolts with the piece that bolts the back onto the base. Was able to get two of the bolts secure but one is still not lined up. With that being said, the base was wobbly but I pushed down on the center piece and it became more stable. I bought this chair for work. I am going to try and sit in it tomorrow. Hopefully I will Love it. If the pieces would line up I believe It would have made it much easier to put together. It took 2:people to put together due to the pieces not lining up. Instructions were fine for us two women.LOL
